Green Hydrogen Project Risk, Arcelor Mittal Rejects €1.3 B, 223 DOE Grants Cut, and LEAG Halts German Hub (2021 to 2026)

Project Viability Risks, 266 GW Canceled Amid Policy and Cost Headwinds

The clean technology sector shifted from a period of ambitious project announcements between 2021 and 2024 to a phase of widespread cancellations and delays from 2025 to 2026, driven by a collision of macroeconomic instability and acute policy reversals. This created a systemic repricing of risk, forcing developers to abandon projects that were no longer financially viable under their original assumptions.

Pre-2025 Expansion and Early Warning Signs

The period leading up to 2025 was characterized by large-scale project announcements, particularly in the US and European offshore wind markets. However, signs of economic stress emerged as early as 2023. The UK’s fifth Contract for Difference (Cf D) auction failed to secure any bids for offshore wind, a direct result of government-set prices being too low to cover developers’ inflated costs. In the US, Ørsted began signaling severe financial pressures on its Ocean Wind 1 & 2 projects, while Ford paused work on its $3.5 billion EV battery factory, citing concerns over operational costs. These events were precursors to the larger wave of cancellations that followed.

The 2025-2026 Great Unwinding

From 2025 onward, economic headwinds intensified and were compounded by significant political shifts, leading to a cascade of project terminations. A December 2025 analysis found that 1, 891 power projects totaling 266 GW of capacity had been canceled in the US alone. This “great unwinding” affected all major clean technology segments.

• Industrial Decarbonization: Arcelor Mittal dropped its major green steel transformation in Germany, turning down €1.3 billion in subsidies due to high energy costs. Similarly, German energy firm LEAG indefinitely postponed one of Europe’s largest green hydrogen hubs.
• Offshore Wind: The sector was hit particularly hard, with Ørsted discontinuing the 2.6 GW Hornsea 4 project in the UK, and Invenergy canceling its 2.4 GW Leading Light Wind project in New Jersey.
• Hydrogen and CCUS: Policy reversals directly caused cancellations. Exxon Mobil halted its Baytown blue hydrogen facility after the US administration pulled federal funding, while Air Products canceled its Massena green hydrogen plant due to changes in tax credit viability. The US clean energy policy shift also saw the Department of Energy rescind $3.7 billion for carbon capture demonstrations.

Arcelor Mittal and Ørsted Lead Cancellations as Billions in Funding Are Pulled

A surge in project cancellations across offshore wind, industrial decarbonization, and carbon capture illustrates a systemic repricing of risk, as developers can no longer absorb escalating costs and policy uncertainty. The write-downs and terminated agreements from market leaders like Ørsted and Equinor, alongside the withdrawal of billions in government funding, mark a definitive end to the era of assuming continuously falling costs.

Offshore Wind’s Economic Reckoning

Offshore wind developers faced a perfect storm of rising interest rates, persistent supply chain inflation, and fixed-price power purchase agreements (PPAs) that made projects unbankable. Ørsted ceased development of its 2, 248 MW Ocean Wind 1 & 2 projects, incurring a $4 billion impairment. Equinor and BP terminated their PPA for the 1, 260 MW Empire Wind 2 project, citing the same economic pressures. This trend was global, with En BW halting its 3 GW Mona and Morgan projects in the UK and India’s SECI canceling 4.5 GW of tenders due to a lack of developer interest.

Industrial Decarbonization Funding Reversals

Projects to decarbonize heavy industry proved highly vulnerable to both market conditions and policy reversals. The cancellation of the German Arcelor Mittal project highlighted how even significant subsidies could not overcome poor market fundamentals. In the US, the impact was more direct. The Department of Energy announced the termination of financial awards for 223 climate-related projects in September 2025, claiming savings of $7.56 billion. This followed an earlier cancellation of $3.7 billion in awards for 24 carbon capture and clean energy demonstration projects, directly impacting companies like Calpine and Exxon Mobil.

US and Germany Face Setbacks as Policy Volatility Derails Major Projects

While project development was globally distributed between 2021 and 2024, the 2025-2026 period saw a concentration of high-profile failures in the United States and Germany. In these regions, abrupt policy shifts and persistent economic challenges combined to create an untenable investment climate for capital-intensive, long-duration clean energy projects.

US Market Disrupted by Policy Reversals

The United States experienced the most acute policy-driven disruption. The change in administration in 2025 led to the direct termination of federal support mechanisms that were foundational to project economics. The US EPA terminated the $7 billion Solar for All program, and the DOE rescinded billions in funding for carbon capture and hydrogen, directly leading to the cancellation of the U.S. Steel Carbon Capture and Exxon Mobil Baytown hydrogen projects. Furthermore, the cancellation of the environmental review for the 6.2 GW Esmeralda 7 Solar Complex effectively halted what would have been the nation’s largest solar project, signaling a hostile federal posture toward large-scale renewables.

Germany’s Industrial Strategy Under Pressure

In Germany, project cancellations were driven more by intractable economics than by direct policy reversal. The country’s high industrial electricity prices and uncertain market outlook for green commodities proved insurmountable. The decision by Uniper‘s potential client, Arcelor Mittal, to halt its green steel project despite a €1.3 billion subsidy offer is the clearest signal of this challenge. The indefinite postponement of LEAG’s green hydrogen hub for similar reasons demonstrates a systemic issue for Germany’s industrial decarbonization strategy, which relies on the availability of cost-competitive renewable energy.

SWOT Analysis: Green Industrial Project Risks and Opportunities

The analysis reveals that while strong long-term demand for decarbonization remains a core strength, immediate threats from policy volatility and macroeconomic pressures have exposed significant weaknesses in project financing models and supply chain dependencies. This has forced a market-wide recalibration of risk and return expectations.

$7.6 B in Grants Cut, Arcelor Mittal Signals Flight to Policy Stability

Moving forward, the most critical factor for project success will be securing flexible offtake agreements and operating in jurisdictions with durable, inflation-adjusted policy support. The era of relying on cheap capital and stable government backing has ended, and developers must now prioritize resilience and risk mitigation in their project planning and site selection.

If Policy Volatility Persists

If abrupt policy shifts continue, especially in the US, capital will increasingly flow toward regions with more stable, long-term regulatory frameworks. Watch for developers to demand more robust contract terms, such as inflation indexation and protections against changes in law, in all future PPAs and offtake agreements. Projects dependent on subsidies without these protections face a high probability of cancellation. The current green hydrogen risk environment shows that projects cannot proceed based on policy assumptions alone.

If Macroeconomic Pressures Ease

Should interest rates and supply chain costs stabilize, watch for a potential wave of M&A activity as financially strong companies like ACWA Power or integrated energy majors acquire distressed assets from canceled or stalled projects. A new cycle of final investment decisions could begin, but project economics will be reset at a new baseline. Expect PPA prices for offshore wind and offtake agreements for green hydrogen and steel to be significantly higher than those seen in the 2021-2023 period, reflecting the market’s costly lessons on risk.
