-
2025 Q4 2025
- PetroChina commissioned a 200 MW power-to-gas facility in Inner Mongolia in October 2025, producing 30,000 tonnes of hydrogen annually for local refineries and chemical plants.
Emerging opportunities added
- Green Hydrogen Exports The global green hydrogen trade is projected to reach 10 million tonnes annually by 2030, with Asia-Pacific and Europe as primary importers. Saudi Aramco’s USD 5 billion NEOM Green Hydrogen Project, operational since Q1 2025, exports 650 tonnes of ammonia-derived hydrogen to Japan and South Korea monthly. This initiative demonstrates the viability of long-distance hydrogen supply chains, with TotalEnergies and PetroChina exploring similar ventures in Oman and Australia.
- Sector Coupling and Circular Economy Integration Power-to-gas is enabling cross-sector synergies, such as converting biogenic CO₂ from waste-to-energy plants into synthetic methane. In Q2 2025, Equinor and a consortium of Nordic utilities launched a pilot in Norway that captures 50,000 tonnes of CO₂ annually from a waste incineration plant, producing 15 million cubic meters of synthetic natural gas. This model aligns with circular economy principles and could unlock USD 12 billion in annual revenue by 2035, according to IEA estimates.

Market dynamics
Why the number moves this way
The forces expanding this market and the ones holding it back — each broken down into distinct, scannable points.
Growth drivers
Pulling the market up
- Renewable Energy Integration The global renewable energy capacity reached 3,870 GW in 2025, creating a surplus that necessitates storage solutions. Power-to-gas converts excess electricity into hydrogen or methane, addressing curtailment losses estimated at 7% of total renewable generation in Europe during 2025. Companies like Equinor are leveraging offshore wind farms in the…
- Government Subsidies and Carbon Pricing The EU Emissions Trading System (ETS) price exceeded €90 per tonne in Q2 2025, making synthetic fuels competitive with fossil alternatives. In the U.S., the 45V hydrogen tax credit, finalized in December 2025, offers up to USD 3 per kg of green hydrogen, catalyzing investments by ExxonMobil and Chevron in power-to-gas projects along the…
- Industrial Decarbonization Demand The steel sector alone accounts for 7-9% of global CO₂ emissions. In March 2025, ArcelorMittal commissioned a 100 MW power-to-hydrogen plant in Hamburg, reducing blast furnace emissions by 20%. Similarly, the chemical industry’s shift toward green ammonia synthesis is driving demand for hydrogen derived from electrolysis, with a projected 12%…
- Grid Stability and Energy Security Power-to-gas systems are being deployed to stabilize grids with high renewable penetration. In Australia, AEMO’s 2025 Integrated System Plan identifies 5 GW of power-to-gas capacity as critical for managing the 80% renewable energy target by 2030. Projects like the Asian Renewable Energy Hub in Western Australia, backed by BP and PetroChina,…
Restraints
Holding it back
- High Capital Expenditure The average cost of a 100 MW power-to-gas facility exceeds USD 500 million, with electrolysis units alone accounting for 60% of expenses. Despite declining electrolyzer costs—down 40% since 2020—financing remains a barrier for mid-sized utilities. The U.S. DOE’s USD 7 billion Hydrogen Hubs program, announced in October 2025, aims to mitigate this but …
- Infrastructure and Supply Chain Bottlenecks The global electrolyzer manufacturing capacity stood at 12 GW annually in 2025, insufficient to meet the 50 GW target set by the Hydrogen Council for 2030. Delays in securing critical components, such as PEM stacks and high-purity membranes, have pushed back commissioning timelines for projects like Shell’s Holland Hydrogen I, origi…
- Regulatory and Certification Gaps The absence of standardized certification for green hydrogen and synthetic methane creates market uncertainty. In Europe, the RED III directive, finalized in April 2025, introduces a framework for renewable fuels of non-biological origin (RFNBOs), but member states are still transposing these rules into national law. This lag has slowed offta…
Trends
What we're watching

Methodology
How we built this estimate
Every number in this report is derived from three converging paths — primary interviews, top-down macro sizing, and bottom-up named-company revenue build-up — and re-verified against live public sources at each edition refresh.
-
Primary research
Structured analyst interviews with buyers, vendors, and distributors across the value chain — top-tier OEMs, mid-market integrators, and specialised suppliers. Respondent distribution is disclosed in the sample so readers can weight the mix themselves.
-
Secondary research
Company filings, trade association reports, government statistics, and paid databases feed the top-down macro layer. Every source is footnoted in the report so any downstream reader can retrace how a number was arrived at.
-
Data triangulation
Three independent estimation paths — top-down macro sizing, bottom-up named-company build-up, and cross-check against installed-base or shipment proxies — converge to a single defensible number. Divergences greater than 8% trigger a re-review.
-
Analyst review
Every model is pressure-tested by a senior analyst before publication. Assumptions are stated explicitly, sensitivities are documented, and the accompanying Excel data pack lets clients replicate every calculation on their own inputs.
