Abstract

Industrial gas is modern industry's most invisible infrastructure. Oxygen that cuts steel, nitrogen trifluoride that etches chips, high-purity hydrogen that drives fuel-cell vehicles, liquid helium that cools MRI magnets — these gases permeate every manufacturing process via pipelines, liquid tankers or cylinders, silently and without fanfare. Industrial gas is both an essential input of the steel era and an indispensable consumable in semiconductor precision manufacturing; it is also the core infrastructure that surfaces when the hydrogen economy emerges.

In 2025, China's industrial gas market broke through the RMB 200 billion mark. Electronic specialty gases accounted for approximately RMB 35–40 billion, bulk industrial gases approximately RMB 120–130 billion, on-site gas services approximately RMB 40 billion, and retail gases approximately RMB 20–30 billion. The global triad — Linde, Air Liquide and Air Products — together still hold more than 60% share in China. However, the catch-up momentum of domestic players is not to be underestimated: Hangyang (Hangyang Co., Ltd.) holds the top position among domestic companies in both bulk gas and on-site manufacturing capabilities; Guanggang Gas has penetrated deeply into the semiconductor electronic bulk-gas segment; Huate Gas has achieved over 90% customer coverage among domestic 8-inch and 12-inch IC fabs for electronic specialty gas certified product lines; and Nanda Optoelectronics has built a supply position in advanced-node materials through precursors and hydrogen-based specialty gases. These four companies form the nucleus of what may be called China's "domestic four horsemen" in the industrial gas localization push.

This report systematically analyzes China's industrial gas sector across twelve dimensions — product classification, global landscape, policy environment, market size, supply-chain structure, key players, regional industrial belts, sub-segment deep dives, technology evolution, risk factors, five-year forecasts and conclusions — and offers major trend judgments for 2026 through 2030.

Core conclusion 1: Electronic specialty gas localization is the sector's greatest structural opportunity. Domestic content rose from under 5% in 2020 to roughly 25% in 2025, driven by the national semiconductor strategy and fab expansion. Beneficiary companies include Huate Gas, Nanda Optoelectronics, Sinochem Bluestar (Haohua) and Jinhong Gas. By 2030 domestic content could exceed 50%.

Core conclusion 2: On-site gas contracts are the most important incremental revenue source going forward. Every new 12-inch fab demands hundreds of millions of Nm³/year of ultra-high-purity gas; the semiconductor expansion wave will drive a surge in long-term on-site contracts of 15–20 years. Guanggang Gas, Hangyang and Yingde Gases are all actively positioning.

Core conclusion 3: Hydrogen energy is the most explosive new track for industrial gas within five years. China's hydrogen energy policy has moved from "pilot exploration" to "orderly breakthrough." Green hydrogen cost continues to fall; Linde, Air Liquide, Air Products and domestic players are all doubling down on hydrogen.

Core conclusion 4: Competition in bulk gas is bifurcating toward two poles — ultra-large on-site manufacturing serving major industrial clients (competed by Linde, Air Liquide, Hangyang and Yingde) and digitally-enabled retail delivery for small and medium customers (entered by some regional operators via platform models). The traditional wholesale middleman tier faces pressure.

Chapter 1　Definitions and Classification: The Internal Map and Full Supply-Chain View of Industrial Gas

Industrial gas spans products from bulk oxygen worth less than RMB 1 per Nm³ to isotope specialty gases priced at thousands of RMB per kilogram — a value density spread of three to four orders of magnitude. To understand competitive dynamics, it is essential to map out the sector's internal taxonomy.

Bulk Industrial Gases: The Derivative Economics of Air

Bulk industrial gases are primarily the products of cryogenic air separation (ASU). Air is roughly 78% nitrogen (N₂), 21% oxygen (O₂) and 0.93% argon (Ar), plus trace rare gases (neon, krypton, xenon). Cryogenic separation compresses, liquefies and fractionates air into its constituent elements. The technology is mature; capital costs are high but marginal unit costs fall sharply with scale.

Major products and downstream uses:

Industrial oxygen (O₂) — China consumes over 200 million tonnes of oxygen equivalent annually. Steelmaking (blast furnace lancing: ~55–60 Nm³/tonne crude steel) is the largest end market; glass melting, non-ferrous smelting and medical use are secondary. Coal-to-chemicals (gasifier oxygen) is another major application.

Industrial nitrogen (N₂) — Inert protection and high-purity carrier gas. Semiconductor fabs require high-purity nitrogen (≥99.9995%) for virtually every process step. Food packaging (nitrogen flush), chemical inert protection, cryogenic freezing (fresh food, biomedical storage) are other applications.

Industrial argon (Ar) — Key noble gas for metallurgy (stainless steel AOD refining), semiconductor (sputtering), precision welding and photovoltaic single-crystal silicon growth (Czochralski puller). China's argon demand grows ~8–10%/year due to PV and semiconductor expansion.

Carbon dioxide (CO₂) — A chemical by-product rather than an ASU product. Food-grade CO₂ (carbonated beverages, fresh-produce atmosphere packaging), welding shield gas and oilfield EOR are major uses; CCUS adds new significance. Kaimete Gas (002549) is a leading domestic food-grade CO₂ supplier.

Industrial hydrogen (H₂) — Mainly derived from industrial by-products (ammonia synthesis off-gas, chlor-alkali by-product, coke-oven gas). Green hydrogen from electrolysis is entering the supply mix as renewable energy costs fall.

Electronic Specialty Gases: The Blood of Semiconductor Manufacturing

Electronic specialty gases (e-spec gases) are produced by complex chemical synthesis and precision purification, requiring purity typically ≥6N (99.9999%) up to 9N (99.9999999%). They are the most technically demanding and highest-value segment of industrial gas.

Core applications in semiconductor manufacturing: NF₃ (CVD chamber cleaning and DCS), C₂F₆ and CF₄ (plasma etch), NH₃ (ALD nitrogen source), SiH₄ (CVD silicon source), KrF and ArF excimer laser gases (photolithography light source), PH₃, AsH₃, B₂H₆ (ion implant dopants, highly toxic), ClF₃ (specialty cleaning gas).

Three distinctive characteristics of e-spec gases drive their high value: (1) extremely tight purity requirements — ppb-level metallic contamination can scrap a wafer batch; (2) a large and diverse product portfolio — an advanced-node fab typically needs 50+ distinct e-spec gases; (3) long customer qualification cycles — replacing a supplier takes 12–18 months of rigorous testing, creating strong customer stickiness and pricing power.

On-Site Production vs. Retail Gas: Two Business Models

On-site (on-site production) — The gas company builds and operates production equipment inside the customer's plant, delivers gas via pipelines under a long-term contract (typically 10–20 years), billed per unit consumption. This is essentially industrial gas "SaaS." Primary customers: large steel mills, large chemical parks, semiconductor fabs, large medical campuses.

Retail (merchant gas) — Gas is produced centrally, filled into high-pressure cylinders or cryogenic liquid tankers and delivered by truck to many smaller customers. Higher unit margins than on-site; competitive on delivery network rather than scale.

Full Supply-Chain View

Upstream: ASU equipment (Hangyang, Sichuan Oxygen, etc.), specialty-gas chemical feedstocks (fluorspar, anhydrous HF), high-pressure vessels (GB-spec cylinders, cryogenic tanks, tube bundles), compressors and liquefaction equipment.

Midstream: Gas production (ASU, electrolysis, chemical synthesis), purification (distillation, adsorption, membrane), gas filling, specialty-gas R&D.

Downstream: Metallurgy, chemicals, electronics/semiconductors, healthcare, food & beverage, welding/cutting, new energy (hydrogen, battery materials).

Chapter 2　Global Landscape: The Triad's World Map and New Challengers

The global industrial gas market (~USD 200–230 billion in 2025) is one of the most highly oligopolistic sectors in industry. Linde, Air Liquide and Air Products together control roughly 65–70% of the global market, a concentration level rare in industrial goods. The root cause: high capital intensity of on-site production (a large ASU can cost RMB 1–20 billion), long-contract customer lock-in (10–20 years), and strong economies of scale (unit cost drops sharply as plant size increases).

Linde (NYSE: LIN) — Global No. 1

Linde was formed in 2018 from the merger of German Linde AG and US Praxair (~USD 85 billion deal), instantly becoming the world's largest industrial gas company by far. FY2025: ~USD 34 billion revenue, adjusted EPS ~USD 14.61, strong free cash flow. Operations in ~100 countries, >70,000 employees. In electronics gas, Linde's "Spectra Gas" brand is among the most important ultra-high-purity specialty gas suppliers globally, covering everything from NF₃ to ArF excimer laser gas mixtures and liquid helium. Linde also operates the world's largest liquid hydrogen production and distribution footprint (US, Germany, Netherlands, China). In China, Linde operates dozens of ASU and specialty-gas facilities serving top-tier customers including Baowu Steel and SMIC.

Air Liquide (Paris: AI) — European Champion

Air Liquide entered China in 1916 — more than a century of presence. FY2025: ~EUR 26.9 billion revenue (+2% comparable), Group operating margin exceeding 20% for the first time in its history, net profit >EUR 3.5 billion, a record. Asia-Pacific delivered EUR 5.12 billion (+1.0%). China Industrial Merchant +2.6%. Air Liquide operates ~140 facilities in 40+ Chinese cities, employs >5,600 in China. In 2025, Air Liquide announced a ~EUR 25 million investment to electrify (steam-to-electricity) its Yulin, Shaanxi ASU, reducing annual CO₂ emissions by ~224,000 tonnes by end-2027.

Air Products (NYSE: APD) — Green Hydrogen Frontrunner

Air Products is the world's largest industrial hydrogen supplier. FY2025 (year end September 30): ~USD 12 billion operating revenue. The GAAP result includes ~USD 3.7 billion pre-tax charges for asset and business disposals; underlying operations remain solid. New management targets 30% operating margin, annual capex cut from USD 5.1 billion to USD 2.5 billion, 3,600 headcount reduction saving USD 250 million/year by 2030. Air Products continues to advance the NEOM green hydrogen project in Saudi Arabia and maintains on-site gas contracts with Baowu and CATL in China.

Taiyo Nippon Sanso (TSE: 4091), Messer, Iwatani

Taiyo Nippon Sanso (TNS/Matheson) — Japan's largest and the world's fourth-largest industrial gas company (now a Mitsubishi Chemical Group subsidiary). Major global NF₃ and high-purity SiH₄ supplier serving Samsung, TSMC and China fabs.

Messer Group — Europe's third-largest independent gas company; niche presence in China via joint ventures.

Iwatani (Japan) — The world's most commercially advanced liquid hydrogen supply chain: operated Japan's first LH₂ transport vessel pilot, built a 180+ station hydrogen station network in Japan. A benchmark for hydrogen energy commercialization globally.

Global Landscape Mapped to China

Foreign companies (Linde + Air Liquide + Air Products + TNS + others) hold ~60–65% combined China share; domestic companies ~35–40%. The split is uneven: domestic companies may hold >40% in bulk gas but still <30% in electronic specialty gas. The overall figure masks this structural divergence.

Chapter 3　PEST Analysis: A Systematic Review of Driving and Constraining Forces

Political and Policy Forces

Semiconductor national strategy and "Big Fund" — National IC Investment Funds I (RMB 140 billion, 2014), II (RMB 200 billion, 2019) and the rumored Fund III (~RMB 300+ billion) fund domestic fab expansion. Each new 12-inch fab demands: ~200–500 million Nm³/year high-purity N₂, ~5,000–10,000 tonnes/year Ar, ~200–500 tonnes/year NF₃. In 2025, SMIC, Huahong, Hefei ChangXin, CXMT and others continue capacity expansion, directly driving e-spec gas demand and creating the market base for Guanggang, Huate and Nanda Optoelectronics to grow.

Hydrogen energy policy deepening — China's Energy Law (effective 2025) legally mandates "orderly promotion of hydrogen energy development." The National Energy Administration (NEA) published the China Hydrogen Energy Development Report (2025) in April 2025, and in June 2025 issued a notice organizing hydrogen energy pilots covering seven scenarios: production, storage-transport, pipeline, liquid hydrogen factories, hydrogen storage, industrial use and transportation. Policy has moved from "pilot exploration" to "orderly commercial breakthrough."

Electronic specialty gas localization "15th Five-Year Plan" target — The 2026–2030 plan targets domestic content in e-spec gases >50% by 2030. MIIT's key R&D programs, first-batch application insurance subsidies and local semiconductor materials funds accelerate progress. Joint qualification labs between fabs and domestic suppliers compress certification timelines.

US export controls — ongoing friction — Since 2022, US controls on China semiconductor supply chains have escalated. While industrial gases themselves are not fully controlled, some high-end e-spec gas formulations (ArF excimer laser gas) carry latent risk. In H1 2026, discussions around expanding controls on electronic chemicals intensified. This pressure has accelerated domestic qualification at Huate, Nanda Optoelectronics and Jinhong.

CCUS and industrial green transition — China's 2030 peak/2060 carbon neutrality targets create both pressure (ASUs are power-intensive) and opportunity (CO₂ capture, green hydrogen, green steel). Multiple major CCUS pilots launched by state enterprises in oil fields (Shengli, Huadong, Changqing) and coal-fired power plants (CHN Energy Taizhou).

Economic Forces

Semiconductor up-cycle pulling e-spec gases — NAND and DRAM prices rebounded in 2024–2025; logic chip utilization recovered with AI computing demand. NF₃, C₂F₆ and NH₃ volumes and prices stabilized and edged up from end-2024. For e-spec companies, this opened a precious window of simultaneous volume and price recovery during the new-capacity ramp-up phase.

Structural divergence in traditional bulk gas downstream — Steel output (~1 billion tonnes, near-flat growth) weighs on oxygen demand; PV, lithium batteries, display panels (new industries) are the incremental bright spots.

Gas price "W-shaped" recovery — Retail oxygen bottomed at ~RMB 0.3–0.4/Nm³ in 2024 (oversupply), recovering to ~RMB 0.5–0.6/Nm³ by 2025. On-site contract prices are locked; retail prices are more volatile.

Power cost pressure — Power accounts for 50–60% of ASU operating costs. Industrial electricity price increases of 20–30% in coastal regions since 2020 have eroded margins for companies without green-power procurement agreements. Sichuan's hydropower-based electricity price advantage (RMB 0.38–0.45/kWh) is a key competitive edge for Qiaoyuan Gas (Sichuan).

Industrial gas financial characteristics: high asset intensity, low marginal cost, superb cash flow quality, differentiated ROCE

Industrial gas is capital-intensive (a 100,000 Nm³/h ASU costs RMB 1–2 billion to build), but once commissioned, incremental unit gas production costs mainly electricity; fixed costs are depreciation, labor and maintenance. This means utilization-rate improvements translate almost directly to EBITDA margin expansion. Long-contract, investment-grade customer receivables create cash flow quality that resembles bond-like annuity streams. The global triad's ROCE (12–20%) reflects decades of this compounding. Domestic companies are climbing toward that level as on-site contract portfolios mature.

Social Forces

Aging population drives healthcare gas demand — China's 65+ population ~15–16% in 2025; hospital construction continues. Medical oxygen (ICU, surgery, hyperbaric oxygen), MRI liquid helium demand grows steadily with high margin and stickiness.

Consumer upgrade drives food-grade gas — Fresh e-commerce and cold-chain logistics expansion boosts CO₂ (carbonation, atmosphere packaging) and liquid nitrogen (quick-freeze) demand. Kaimete Gas benefits from this trend.

Industrial safety regulation tightening — Stricter hazardous chemical production oversight since 2024 forces equipment upgrades; leading companies benefit from compliance-driven market consolidation.

Urbanization, manufacturing upgrading as long-term structural drivers — As China's manufacturing base shifts from commodities to precision, each factory's gas consumption moves from "low-cost bulk" toward "high-purity specialty" — unit gas value improves even if total volume slows.

Technology Forces

Ultra-large ASU (≥120,000 Nm³/h) domestic production — Hangyang can now independently design and build 120,000 Nm³/h ASUs, breaking foreign monopoly on the largest-scale on-site projects.

E-spec gas ultra-purification toward 9N — Domestic leaders have achieved 7N (99.99999%) in volume production; 8N–9N iteration is the 2025–2028 key technical race.

Green hydrogen cost falling — NEA estimates ALK electrolysis production cost ~RMB 17/kg at RMB 0.25/kWh electricity, approaching coal-derived gray hydrogen parity. The commercial tipping point approaches.

Digital operations and AI optimization — Digital twins, IIoT and AI-based load scheduling reduce ASU energy consumption by 5–10% in commercial deployments (Yingde × Lingyang, Hangyang new stations).

Chapter 4　China Market Size: The Three-Layer Structure of a RMB 200 Billion Market

Total Scale: Crossing the RMB 200 Billion Mark in 2025

China's industrial gas market in 2025: RMB 200–250 billion overall (neutral estimate ~RMB 200–230 billion). Breakdown: electronic specialty gas ~RMB 35–40 billion (CAGR ~15–20%); bulk industrial gas ~RMB 120–130 billion (CAGR ~5–7%); on-site service ~RMB 35–45 billion (CAGR ~10–12%); retail gas ~RMB 20–30 billion (CAGR ~3–5%). China accounts for ~14–16% of global market, the world's second-largest single-country market after the US.

Sub-Segment Divergence

Bulk gas (~RMB 120–130 billion): Dominated by oxygen, nitrogen and argon; steel and chemicals are the largest downstream. Growth is moderate; new-energy manufacturing (PV, batteries) provides incremental demand. The competitive logic is "scale wins" and "contract locks." Dominant players: Linde, Air Liquide, Air Products, Hangyang, Yingde Gases.

Electronic specialty gas (~RMB 35–40 billion): Fastest growing; CAGR >15%. NF₃ is the highest-volume single product domestically; fluorinated etch gases (C₂F₆, CF₄, CHF₃) follow; photolithography laser gases (KrF/ArF) still predominantly imported. Every percentage-point of domestic share gain represents ~RMB 300–400 million of incremental domestic market.

On-site service (~RMB 35–45 billion): Annuity-like cash flows with high visibility. Semiconductor fab ramp-ups in 2025 released concentrated on-site demand; Guanggang, Hangyang and Yingde all signed new contracts.

Localization Rate: Electronic Specialty Gas — Historical Milestone

Bulk gas: >60% domestic — ASU equipment: Hangyang holds >70% of the domestic market. Total bulk gas domestic production: >60%.

E-spec gas: ~20–25% domestic — 2020: <5%; 2022: ~14%; 2024: ~20%; 2025: ~22–25%; 2030 policy target: >50%. The "structural divergence" caveat: NF₃ domestic content may already be 40–50%+; KrF/ArF photolithography gas is still <5% domestic.

Market Share

Linde: ~18–22%; Air Liquide: ~10–13%; Air Products: ~5–8%; TNS and other Japan: ~4–6%; Hangyang: ~8–10%; Yingde: ~6–8%; Guanggang Gas: ~1–2%; Huate Gas: ~1–2%; other domestic: ~15–20%.

Chapter 5　Supply Chain Analysis: Six Key Nodes from ASU to End Delivery

Node 1: Air Separation Equipment — The Hardware Origin of Bulk Gas

A complete cryogenic ASU consists of: air compressor (centrifugal turbine or piston compressor, the single highest-energy-consumption component); air pre-cooling and purification (molecular sieve removes H₂O, CO₂, hydrocarbons); plate-fin heat exchanger (cryogenic cold box); distillation columns (double-column separation); cryogenic liquid storage and vaporization systems. Hangyang dominates China's ASU market (>70% domestic share) and in 2025 delivered multiple 100,000 Nm³/h-class ultra-large ASU projects in Yangtze River Delta and Pearl River Delta steel and chemical parks.

Node 2: On-Site Gas Service — The Core Commercial Moat

Key competitive dimensions: capital cost control (total investment for a 100,000 Nm³/h ASU is RMB 10–20 billion); long-contract negotiation (price, minimum take-or-pay, term); operational efficiency (energy optimization = direct margin); financing cost (lower cost enables more competitive pricing, a structural advantage for the global triad). Yingde Gases (privatized 2018, ~120+ on-site facilities in mainland China, >20% of China independent on-site gas market) is the leading domestic pure-play on-site operator. Hangyang's gas service business became its largest revenue segment in 2025 (61% of total revenue). Qiaoyuan Gas (300842) dominates Southwest China with water-powered electricity cost advantage.

Node 3: Electronic Specialty Gas Synthesis and Purification — The Highest Technical Barrier

Synthesis: fluorine chemistry (HF, fluorspar derivatives) as raw materials for NF₃, C₂F₆, CHF₃. Purification: from ~99.99% crude to ≥99.9999% e-spec quality requires multi-stage cryogenic distillation, deep molecular sieve adsorption (achieving 1 ppb H₂O removal), all-metal-free PFA tubing systems, and online QMS feedback control. Qualification: "Evaluation → Qualification Lot → Production Qualification → Approved Supplier" — typically 12–18 months, large time and resource investment per product.

Node 4: Storage and Transport Equipment — The Vascular System

High-pressure cylinders, cryogenic liquid tankers (20–45 m³ liquid capacity), cryogenic storage tanks, ultra-cold liquid hydrogen tanks (-253°C, extreme insulation requirements). Smart cylinder IoT (RFID, QR codes, pressure sensors) is being widely deployed; China's SAMR has pushed IoT cylinder management standards since 2025.

Node 5: Logistics and Distribution Network — Source of Regional Moats

Cryogenic liquid gas has an economical transport radius of 300–500 km — explaining why gas markets have strong regional character. In many provincial markets, 2–3 players hold 80% share; no single national player exceeds 20%. Qiaoyuan in Sichuan, Jinhong in the Yangtze River Delta: textbook regional moat examples.

Node 6: Retail Gas and Value-Added Services

Retail is the lowest-margin but most numerous customer segment: tens of thousands of small welding shops, hospitals, labs and food manufacturers. Digital retail (app-based ordering, cylinder IoT tracking, platform aggregation) is reshaping this tier, reducing intermediary layers. Value-added services (gas solution design, equipment maintenance outsourcing, safety training, usage analytics) improve customer retention and differentiate premium suppliers.

The sector's entry barriers deserve a dedicated note: high capital intensity, long-contract customer lock-in, and the "certification maze" for e-spec gases collectively mean that very few "pure new entrants" have succeeded in this industry. Successful domestic players all trace roots to state-owned gas spinoffs (Hangyang, Sichuan Oxygen), regionally-built networks (Qiaoyuan, Jinhong) or upstream chemical extensions (Haohua, Nanda Optoelectronics).

Chapter 6　Key Company Profiles: Twelve Players' FY2025 Portraits

Hangyang Co., Ltd. (002430): Integrated Champion

The only domestic company with full national competitive capabilities in both ASU equipment manufacturing and downstream gas operations. FY2025: revenue RMB 15.08 billion (+10.0%), net profit RMB 949 million (+2.9%), gas service revenue RMB 9.21 billion (+13.7%, 61% of total), overseas revenue RMB 973 million (+30.0%). The gas business became the largest revenue driver as the company accelerates its transformation from "equipment maker" to "comprehensive gas service provider."

Guanggang Gas (688548): Electronic Bulk Gas Specialist

Positioned as China's leading electronic bulk gas specialist, leveraging Guangzhou Iron & Steel Group heritage to serve semiconductor and electronics industrial parks with ultra-high-purity on-site bulk gas. FY2025: revenue RMB 2.42 billion (+15.3%), net profit RMB 286 million (+15.4%), asset-liability ratio 32.2%. Reversed seven consecutive quarters of "revenue growth without profit growth." New electronic bulk gas projects signed in Shenzhen, Nantong and Guangzhou for expanding wafer fabs.

Huate Gas (688268): Electronic Specialty Gas Width Champion

The widest product portfolio of e-spec gases among domestic companies; >90% coverage of domestic 8-inch and 12-inch IC fabs. FY2025: revenue RMB 1.42 billion (+1.7%), net profit RMB 135 million (-26.8%). The profit decline reflects high depreciation from newly-commissioned production lines — not volume erosion. Photolithography gas volumes grew significantly; fluorinated and hydrogen gas products maintained market leadership. The "certification width" moat: replicating 90%+ fab coverage would take any new entrant 5–10 years and tens of billions of RMB; the barrier is time itself.

Nanda Optoelectronics (300346): Technical Depth Pioneer

Dual-core in precursor materials (ALD/CVD metalorganic precursors) and electronic specialty gases (hydrogen-type special gases: PH₃, AsH₃, B₂H₆). Born out of Nanjing University's chemistry department, holding core patents in metalorganic precursor synthesis. 9M FY2025: revenue RMB 1.88 billion (+6.8%), net profit RMB 301 million (+13.2%). H1 precursor gross profit contribution +50%+ YoY; ARC, BF₃ and other new IC products +60%+ YoY. Entered qualification cycles at TSMC Nanjing and SMIC.

Kaimete Gas (002549): CO₂ Specialist Pivoting to Semiconductor Gases

Specialty in food-grade CO₂ and industrial hydrogen; now pivoting toward electronic bulk and specialty gases. FY2025: revenue RMB 627 million (+6.6%), net profit RMB 68.6 million (turned profitable from RMB -49 million in prior year), non-GAAP net profit +3720%, admin expenses -36%. CO₂ revenue RMB 217 million (+14.6%), hydrogen RMB 215 million; together 69% of sales. E-spec revenue ~2% only, but the loss of Yueyang Electronic Gas subsidiary narrowed significantly.

Jinhong Gas (688106): Yangtze River Delta Comprehensive Gas Platform

The Yangtze River Delta's most important comprehensive gas supplier, covering 100+ products and a distribution network centered on Suzhou/Zhejiang/Shanghai. FY2025: revenue RMB 2.78 billion (+10.0%), net profit RMB 132 million (-48.7%). The 49% profit decline reflects newly-commissioned capacity entering depreciation without full volume ramp and aperiodic bulk gas price depression. Growth logic is "build scale first": once prices recover and capacity fully ramps, scale effects convert to earnings leverage.

Qiaoyuan Gas (300842): Southwest High-Margin Specialist

Deep-rooted in Southwest China (Sichuan base), combining on-site and retail gas. 9M FY2025: revenue RMB 797 million, net profit RMB 181 million, net margin 22.7% — among the highest in the industry. Core advantage: Sichuan hydropower electricity price (RMB 0.38–0.45/kWh vs. national ~RMB 0.55–0.70/kWh). Strategy: "organic expansion + cross-provincial M&A" extending the Sichuan base into Guizhou, Yunnan and Chongqing.

Yingde Gases (Privatized): China's Flagship Independent On-Site Producer

China's largest independent industrial gas producer; top-3 globally for independent on-site services. Taken private in 2018 (PAG-led MBO from Hong Kong Stock Exchange); IPO plans mooted multiple times but not yet executed as of H1 2026. 120+ on-site facilities in mainland China serving Baowu, Hualing, Anyang Steel and others. >20% of China's independent industrial gas market. 2025 "LEAP" five-year strategy: business expansion (semiconductor parks), management upgrade (digital operations), capital action (IPO or strategic financing). Partnership with Alibaba's Lingyang for AI-based gas station digital twin. Differentiated from Hangyang: pure on-site operator with no equipment manufacturing.

Haohua Science & Technology (600378): State-Level Fluorine E-Spec Gas Platform

The most important fluorine-based e-spec gas platform in China, with its subsidiary Sinochem Bluesky (PERIC Special Gases) operating China's largest NF₃ production line. The Hohhot base (Inner Mongolia): NF₃ Phase 1 (7,500 tonne/year) and NH₃ (10,000 tonne/year) came on stream in 2025. With domestic production of NF₃ now scaling up, Haohua has moved from import-substitution to export-competitive logic.

Yake Technology (002409): Semiconductor Materials Platform

Transformed from traditional organic chemicals to a semiconductor materials platform; e-spec gases (C₄F₈, NF₃) and precursors are key growth businesses. Semiconductor materials segment continued strong growth in 2025; qualification push for high-end etch gases and ALD precursors ongoing.

Linde (China), Air Liquide (China), Air Products (China)

The three foreign giants maintain deep roots in China with decades of local investment, long-term contracts and local teams. Linde's China revenue is estimated >RMB 10 billion, the largest single foreign player. Air Liquide operates 140+ facilities across 40+ cities. Air Products holds major on-site contracts with steel and semiconductor clients. In the highest-end e-spec niche (KrF/ArF photolithography laser gases, ultra-pure rare gas blends), foreign companies still have an advantage domestic players are not yet fully positioned to replace.

Chapter 7　Regional Industrial Belts: The Geographic Map of Gas Production

Zhejiang Hangzhou — Hangyang's R&D and manufacturing headquarters; the national center for ASU equipment expertise with a supplier cluster of heat exchangers, valves and compressor components.

Guangdong (Guangzhou/Shenzhen) — Electronic bulk gas hub for the Pearl River Delta. Guanggang Gas (688548) is the dominant domestic player; Shenzhen's semiconductor design and manufacturing cluster drives strong demand. Linde and Air Liquide both operate key facilities.

Jiangsu Province — The most concentrated province for domestic e-spec gas localization. Nanjing: Nanda Optoelectronics (precursors + H-type special gases) + TSMC Nanjing fab. Suzhou: Jinhong Gas headquarters + semiconductor and optical electronics cluster. Wuxi/Nantong: Huahong Wuxi 12-inch fab ramp-up + semiconductor packaging parks.

Sichuan (Chengdu/Leshan/Zigong) — Southwest industrial gas hub. Qiaoyuan Gas headquarters; hydropower electricity advantage (RMB 0.38–0.45/kWh). Service area extends to Guizhou, Yunnan and Chongqing.

Inner Mongolia/Xinjiang — Strategic bases for green hydrogen and fluorine-based e-spec gases. Haohua/PERIC's NF₃ + NH₃ production in Hohhot leverages local fluorite resources and energy advantage. Xinjiang's ultra-cheap solar electricity (potentially RMB 0.15–0.20/kWh) makes it a top candidate for green hydrogen scale-up.

Central China (Wuhan/Changsha) — Traditional steel and chemicals gas market; growing photonics and new-energy manufacturing (CSOT, BOE Wuhan) creating new high-purity gas demand.

Shandong/Henan — Major northern bulk gas consumption bases for chemicals (Wanhua Chemical, Luxi Chemical) and coal-to-chemicals.

Foreign giants' China footprints — Linde: Shanghai, Shenzhen, Wuhan, Tianjin, 30+ plants; Air Liquide: 140+ facilities across 40+ cities; Air Products: key on-site bases in East and South China. The three giants collectively represent hundreds of billions of RMB of accumulated investment in China.

Bulk Industrial Gases (O₂/N₂/Ar/CO₂/H₂): Volume Game

Bulk gas is the largest segment by volume (~RMB 120–130 billion, 2025). Stable base: steel remains the #1 oxygen consumer. Growth engine: PV silicon ingot and battery material production driving argon and nitrogen demand. Competition logic: "scale wins," "long contracts lock customers."

Argon is the performance star: PV (Czochralski puller requires high-purity Ar protection), semiconductor (sputtering, CVD), specialty welding — demand growing ~8–10%/year. Argon supply tightened 2023–2025, prices above historical averages, benefiting large ASU operators. Regional price differentials are significant: semiconductor clusters in Yangtze River Delta command premium argon pricing; Sichuan/Inner Mongolia have lower costs.

Electronic Specialty Gases (NF₃/SiH₄/KrF/Xe/NH₃ etc.): Certification Race

NF₃: 25,000–30,000 tonne/year global demand; China is the largest consumer (35–40%). Domestic production by PERIC (Haohua), Huate and others is scaling; NF₃ domestic content among certified fabs may already exceed 40–50%. A landmark in the localization story.

Fluorinated etch gases (C₂F₆, CF₄, CHF₃): Huate Gas, Jinhong Gas certifications mature; some fabs at 100% domestic procurement.

Excimer laser gas (KrF/ArF): Still dominated by Linde and TNS. Domestic qualification window estimated 2027–2028. This is the most critical remaining "fort" to be taken in the localization campaign.

Rare gases (Xe, Kr, Ne): By-products of large ASU micro-recovery. Ukraine's role in global Ne/Kr/Xe supply disrupted since 2022; China is building domestic purification capacity as domestic ASU scale grows. Helium: 100% import-dependent (US, Qatar, Australia, Russia); most fragile supply item in China's manufacturing supply chain.

High-purity NH₃: Large breakthrough with PERIC's 10,000 tonne/year plant; key challenge is ultra-purification to ppb-level metal impurity control.

Hydrogen Energy Gas: From Industrial By-Product to Green Infrastructure

China 2024 hydrogen production/consumption: >36.5 million tonnes/year, #1 globally; but ~80% is "gray" (chemical by-products, coal gasification). Green hydrogen (electrolysis): <2% of total in 2025 but growing ~40%/year. First commercial liquid hydrogen plants commissioned 2025 (primarily for aerospace and heavy-duty FCEV fueling stations). ALK electrolyzer: essentially fully domestic (Longi Hydrogen, Sungrow, etc.). PEM electrolyzer: rapid domestic progress, costs falling toward RMB 5,000–8,000/kW.

Fuel cell vehicles: 540+ hydrogen fueling stations commissioned by end-2024; ~24,000 FCEV commercial vehicles in service. Hydrogen heavy-truck demonstration corridors (e.g., Shanghai–Ningbo) launched in 2025.

CO₂ Capture and CCUS: On the Eve of Scale-Up

China CCUS operating and under-construction capture capacity >3 million tonnes CO₂/year by 2025. Key projects: Sinopec Shengli oilfield (EOR, 1 Mt/year), CHN Energy Taizhou power plant (0.5 Mt/year). CO₂-EOR economics: each tonne CO₂ injected yields ~0.4–0.8 barrels incremental oil, making CCUS self-funding at USD 50–80/barrel oil prices. Green steel (hydrogen direct reduction iron, DRI) is industrial gas's most significant long-term new demand horizon: each tonne of DRI requires ~55–60 kg H₂; scaling to 10 Mt DRI/year demands ~500,000–600,000 tonnes H₂/year.

Medical Gas: High-Margin Stable Growth

Medical oxygen (ICU, surgery, hyperbaric chambers), N₂O (anesthesia), medical CO₂ (laparoscopic surgery), medical air — regulated by the Chinese Pharmacopoeia, requiring medical device production licenses. High barrier, strong customer stickiness, higher margin than industrial uses. Aging population and healthcare infrastructure expansion drive steady demand. Liquid helium (MRI magnet cooling): 100% import-dependent, most fragile supply item.

Welding Gas: Traditional Bulk with Digital Transformation Opportunity

The largest single-application retail gas market. Main products: Ar or Ar/He for TIG/MIG welding; CO₂/Ar mix for MAG; acetylene for flame cutting. Market is highly fragmented (thousands of regional distributors). Laser cutting is displacing traditional acetylene flame cutting, pressuring acetylene but creating high-purity N₂ demand. Brand-chain retail consolidation is the emerging trend.

Food-Grade Gas: Cold-Chain Economy's Gas Foundation

CO₂ and N₂ are the primary food industry gases. MAP (Modified Atmosphere Packaging) penetration rose from ~15–20% in 2015 to ~35–40% in 2025, driving sustained demand for food-grade CO₂/N₂ blends. Food-grade CO₂ must meet GB 10621 (purity ≥99.9%, total sulfur ≤0.1 ppm, benzene ≤0.02 ppm), creating a higher barrier than industrial CO₂.

Rare Gases (Xe/Kr/He): Scarcity-Driven Pricing

Noble gases are the highest value-density industrial gas products. Xe is ~0.09 ppm in atmosphere; producing one m³ liquid xenon requires processing ~10 million m³ of air — economically viable only at very large ASU scale. The Ukraine conflict since 2022 disrupted up to 25–30% of global Ne/Kr/Xe supply, driving prices sharply higher and accelerating China's domestic purification capacity build-out. Helium requires specific natural gas reservoir geology (US, Qatar, Australia, Russia); China has no meaningful domestic production and faces structural supply-chain vulnerability.

Chapter 9　Technology Evolution: The Long March from 120,000 Nm³/h ASU to 9N Specialty Gas

Ultra-Large ASUs: Pushing the Scale Frontier

Hangyang's 120,000 Nm³/h capability breaks the historical dependency on foreign engineering for the largest on-site projects. Key technical challenges: large turbine compressor axial clearances (micron precision at thousands of rpm); super-cold large heat exchanger thermal efficiency (near-zero temperature-difference design); large distillation column stable operation (gas-liquid two-phase distribution in packing/distributor design). These remain areas of gap between Chinese and world-class technology, driving Hangyang's ongoing R&D investment.

E-Spec Gas Ultra-Purification: Exponential Challenge from 7N to 9N

From 5N (99.999%) to 7N (99.99999%): impurity concentration drops 100× (10 ppm → 0.1 ppm). From 7N to 9N: another 100× reduction (100 ppb → 1 ppb). At ppb levels, any micro-contamination source (metal oxide particles from tube walls, valve material leachate, residual gas in fill system) can reject the batch. Mainstream 7N purification routes: multi-stage cryogenic distillation; deep molecular sieve adsorption (TSA/PSA, removing H₂O and O₂ to 1 ppb); all-metal-free PFA/PVDF piping; inline QMS (quadrupole mass spectrometry) closed-loop control.

Hydrogen Liquefaction and Green Hydrogen Technology

Liquid hydrogen (LH₂): boiling point -253°C (57°C colder than liquid nitrogen), requiring extreme thermal insulation. Production via Claude Cycle liquefaction; world-class plants achieve 8–10 kWh/kg H₂. China's first commercial LH₂ plants commissioned 2025; efficiency gap vs. Linde/Iwatani is narrowing. Green hydrogen cost structure: power ~70–75% of cost. Break-even vs. coal-derived gray hydrogen (RMB 10–12/kg) expected ~2027–2028 in best-resource provinces (Inner Mongolia, Xinjiang).

Digital Operations: From Automation to Intelligence

AI-based advanced process control (APC) in large ASUs achieves ~3–8% energy savings. Digital twins enable virtual optimization simulations without plant shutdown. Predictive maintenance (vibration sensors + ML models) reduces unplanned downtime by 30–50%. Smart cylinder IoT: RFID + pressure sensors enable real-time tracking, automated reorder, full lifecycle management. 2025: SAMR IoT cylinder management standards rolled out nationwide.

Electronic Specialty Gas Quality Monitoring and Supply Chain Traceability

Online APIMS (atmospheric pressure ionization mass spectrometry) or CRDS (cavity ring-down spectroscopy) for real-time outlet gas quality monitoring. Full-batch traceability from raw material through synthesis, purification, filling to delivery — required by customers (wafer fabs) and essential for root-cause analysis in quality incidents. The global leaders (Linde, TNS) have mature digital supply chain management; domestic companies are catching up.

Semiconductor Process Shrink Drives E-Spec Gas Demand Structural Shift

Smaller nodes = more process steps = higher total gas consumption per wafer. Specific high-impact products: TMA (trimethylaluminum) for ALD high-k dielectrics; WF₆ for tungsten contact fill (tighter tolerances as via dimensions shrink); HBr (high-purity hydrogen bromide) for selective etch in advanced logic; increasingly stringent requirements on ultra-high-purity Ar and N₂ carrier gases (ppb→ppt metal level). Process node upgrades therefore create internal demand growth even without fab capacity expansion.

Carbon Footprint Management: New Competitive Dimension

Major semiconductor customers are beginning to include supplier carbon footprints in procurement criteria. Air Liquide's Yulin ASU electrification (2025 announcement, 2027 completion: -224,000 tonnes CO₂/year). Qiaoyuan's hydropower-based electricity gives it a natural low-carbon product advantage. Green electricity procurement (direct purchase agreements, green certificates) is becoming a new competitive variable for gas companies.

Chapter 10　Risk Analysis: Six Shoals of the Industrial Gas Industry

Risk 1: Semiconductor Cyclical Downturn — E-spec gas demand tracks fab utilization rates near-linearly. If AI chip demand disappoints, inventory rebuilds and fabs cut output, e-spec gas volumes and prices will both decline. Companies with heavy depreciation from recent expansion (e.g., Huate Gas) are most exposed in a downturn.

Risk 2: Power Cost Spike — Power is 50–60% of ASU operating cost. Industrial electricity price increases of 20–30% in coastal regions since 2020 have already eroded margins. Extreme drought (reducing hydro power output) is a cyclical shock specific to Southwest China operators like Qiaoyuan Gas.

Risk 3: International Supply Chain Disruption — Helium: 100% import-dependent, highly concentrated global supply with unpredictable geopolitical risk. High-end turbine compressors: Siemens, Ansaldo still referenced for leading-edge designs. KrF/ArF laser gases: globally concentrated among Linde, TNS, Kanto Denka.

Risk 4: US Export Control Expansion — Industrial gases are not currently on the Entity List, but high-end e-spec gas formulations (ArF laser gas blends) carry latent risk. A "black swan" expansion of controls would create short-term supply shocks but paradoxically accelerate domestic substitution — the long-term effect would benefit domestic e-spec gas companies.

Risk 5: Safety Accidents and Major Compliance Events — High-pressure cylinders (explosion risk), liquid oxygen (strong oxidizer), liquid hydrogen (extremely flammable, 4–75% explosion range), AsH₃/PH₃ (acutely toxic), NF₃ (supports combustion at high temperature). A major accident triggers industry-wide safety inspections and production shutdowns. Regulatory scrutiny of hazardous chemicals has intensified since 2024. Compliance capability is increasingly a competitive differentiator — when competitors are forced to halt operations, compliant leaders absorb displaced customers.

Risk 6: Customer Concentration and Long-Contract Maturity Risk — A single large 10–20 year on-site gas contract that terminates (customer re-tenders, builds own facility, or shuts down) represents large sudden revenue loss. Mid-tier gas companies with >30–40% revenue from a single customer are especially vulnerable. Semiconductor fab on-site contracts are more technically binding but are still subject to fab utilization variability.

Comprehensive risk profile: Moderate-to-low systemic risk (demand diversification across multiple non-synchronized cycles, long contracts provide resilience) + differentiated non-systemic risk by sub-segment and company type (e-spec companies face higher technical validation and semiconductor cycle risk; pure bulk companies face price cycle and new-entrant competition risk; pure on-site companies face contract maturity concentration risk).

Chapter 11　2026–2030 Forecasts: Four Core Change Curves for Five Years

Curve 1: Total Market — From RMB 200 Billion to RMB 300–350 Billion

CAGR estimate: 7–10%. Upside: e-spec gas demand from fab expansion (CAGR ~15–18%), hydrogen energy commercialization, on-site contract pipeline at historical highs, medical gas steady growth, green steel hydrogen demand acceleration. Downside: bulk gas downstream (steel, building materials) near-zero growth, gas price cyclicality, new entrants in regional markets, rising capital costs constraining new on-site investments, possible semiconductor cycle downturn. Neutral CAGR 8%: 2030 market ~RMB 330 billion. Optimistic (CAGR 10%): ~RMB 350 billion. Conservative (CAGR 7%): ~RMB 310 billion.

Curve 2: E-Spec Gas Domestic Content — From 25% to 50% (Historical Inflection)

Path is non-linear with specific technical milestones:

2025–2026: NF₃, C₂F₆, NH₃, PH₃ certified products scale up; target ~30% domestic content. Key transition: "few fab certifications" → "mainstream fab procurement."

2026–2028: KrF/ArF excimer laser gas and ultra-high-purity SiH₄ (9N) are the critical assault targets. If achieved, domestic content could jump from 30% to 40%. Huate Gas and Nanda Optoelectronics are the most likely companies to reach this milestone; Haohua is advancing fluorine-based high-end specialty gases in parallel.

2028–2030: Noble gas (high-purity Kr, Xe) purification/recovery and ultra-high-purity precursors are the final frontier. Whether the 50% target is truly achieved hinges on sustained policy support and R&D intensity in this phase.

The structural caveat: 50% aggregate domestic content does NOT mean every product reaches 50% — some standard products (NF₃, C₂F₆) may already be 50%+ domestic by 2028; photolithography laser gases may still be <10% domestic by 2030. The aggregate number masks substantial product-level divergence.

Key policy catalysts: joint fab-supplier qualification labs can compress certification timelines from 18 to 12 months; MIIT "first-batch application insurance" reduces fab risk cost for adopting unqualified domestic materials; supplier localization KPIs being embedded in some fabs' operating guidelines under supply-chain security pressure.

Curve 3: Hydrogen Energy Gas — From "Track" to "Infrastructure"

Hydrogen energy as an industrial gas growth curve will undergo the transition from "policy track" to "commercial infrastructure" in 2025–2030. Commercial viability threshold: green hydrogen cost ≤RMB 15/kg, achievable in Inner Mongolia/Gansu/Xinjiang ~2027–2028. At that point, commercial scale-up moves beyond subsidies.

Highest-priority hydrogen consumption scenarios: green steel (hydrogen direct reduction of iron, replacing coke); hydrogen heavy-duty trucking (on economically-viable routes, total lifecycle cost approaching diesel); industrial hydrogen replacing gray hydrogen in ammonia and methanol synthesis (reducing carbon footprint).

Gas companies' role: build and operate large-scale green hydrogen supply stations (replicating the on-site gas model — long-term supply contracts with industrial customers). Capital deployed by Linde, Air Liquide, Air Products, and Hangyang signals this is the next major frontier battle in the China market.

Specific 2026–2030 forecasts: hydrogen energy gas share of total industrial gas revenue: 3–5% in 2025 → 8–12% by 2030; absolute market size RMB 30–50 billion by 2030 (CAGR 25–35%). True large-scale breakout (RMB 100B+ market for hydrogen energy gas) will likely occur post-2030 once hydrogen metallurgy scales up.

Curve 4: Competitive Landscape — Domestic Players from 40% to 50%

By 2030, domestic industrial gas companies' combined market share is projected to rise from ~40% to ~50–55%. Structure of share shift: on-site bulk gas domestic share rises from ~40% to 45–50% (Hangyang and Yingde new contract pipeline); electronic specialty gas domestic share rises from ~25% to 40–50% (certified product expansion and capacity ramp-up); retail gas domestic share already >60%, digital platforms drive further optimization.

Foreign triad's moat in premium e-spec (photolithography laser gas) and large comprehensive on-site projects remains significant in the near term. But the overall trend is gradual and irreversible share erosion for foreign players. This will play out not as "displacement" but as "domestic players capturing the majority of incremental market growth" — while foreign absolute revenue scale may not shrink, relative share will gradually decline. This "coexistence equilibrium" is the most common competitive steady-state in mature industrial goods markets.

Chapter 12　Conclusions: The Quiet Transformation of an Industry

Industrial gas is the quietest revolutionary in industry. It does not announce itself, does not make headlines, yet day after day in semiconductor fab cleanrooms, in the chill haze around liquid hydrogen tanks, in front of the oxygen lance at electric arc furnaces, it determines where the frontier of advanced manufacturing lies.

Reviewing the twelve chapters of this report, the logic of China's industrial gas industry can be distilled into a few clear narrative threads:

Thread 1: The triad's foundations hold — but the distance is now visible to the naked eye

Linde, Air Liquide and Air Products' >60% China share was not achieved overnight; it is the product of decades of sustained investment. Air Liquide has been in China since 1916. Linde combines Praxair's global engineering heritage with cutting-edge electronics gas technology. Air Products takes the most aggressive stance in green hydrogen globally. Their moat is a composite of capital, technology, engineering capability and customer relationships that will not be shaken in the short term.

Yet the distance is now visible. Hangyang's 120,000 Nm³/h ASU capability means the largest domestic projects can now be built entirely with domestic equipment. Guanggang Gas and Huate Gas are dismantling fab-by-fab the historic lock-in of foreign e-spec gas suppliers. Nanda Optoelectronics is cracking the "all-import" regime for advanced-node precursor materials. These are early signals of an industry undergoing transformation.

Thread 2: E-spec gas localization is this generation's most important domestication battle

Mirroring the path of display panels, solar cells and power batteries, the trajectory is: enter from easy products (NF₃, C₂F₆), advance toward harder ones (KrF/ArF laser gas, ultra-high-purity precursors). The goal (>50% domestic content by 2030) is clear; the pace is difficult, but the direction is irreversible. Every qualified new product line is a direct displacement of foreign supplier share. Participants — Huate Gas, Nanda Optoelectronics, Haohua, Jinhong, Yake Technology — are trading time for access passes, and each pass counts.

Thread 3: Hydrogen energy is industrial gas's second growth curve — not science fiction

What is different this time: solar electricity costs have reached historic lows, removing the critical constraint on green hydrogen cost (power cost). China has the world's largest hydrogen consumption scenarios. The Energy Law and NEA pilot framework are in place. Industrial gas companies are natural builders of hydrogen energy infrastructure — they have long-contract on-site operating experience, large facility O&M capability, and established long-term industrial customer relationships. Moving from industrial gas to hydrogen supply is a "horizontal drift" of the business model, not a disruptive reinvention.

Thread 4: The domestic four horsemen represent four different localization paths

Hangyang: full-chain integration from equipment to service — unique in combining ASU manufacturing and gas operations; moat from full-chain technical control and equipment cost leadership.

Guanggang Gas: vertical specialization in electronic bulk gas on-site — follows fab expansion, charges premium for high-purity requirements, secures certainty via long contracts.

Huate Gas: certified product width moat — invested time to achieve >90% fab coverage certifications; represents the "widest product portfolio" path.

Nanda Optoelectronics: technical depth path from university spinoff — leverages Nanjing University chemistry heritage, specializes in the highest-barrier, least-localized precursors and high-toxicity specialty gases.

The quiet transformation of industrial gas has been underway for many years and will continue for many more. History has proven repeatedly that when a country accumulates sufficient engineering capability and scale economics, even an oligopolistic industry structure is gradually reshaped by the weight of time. Industrial gas will be no exception.
