Mandates Create Offtake Certainty for CO2-Based E-Fuels

ReFuelEU Aviation, which entered force in 2025, sets a 2% sustainable aviation fuel blending obligation rising to 70% by 2050, with a nested 1.2% sub-mandate for synthetic Power-to-Liquid e-fuels by 2030. For carbon-capture operators and e-fuel producers, these percentages translate directly into guaranteed offtake volumes: airlines and fuel suppliers face non-compliance penalties if they fail to meet the trajectory. The regulation defines renewable fuels of non-biological origin—often derived from captured CO2 and green hydrogen—as central to long-term decarbonisation, giving project sponsors a predictable revenue floor and allowing lenders to model cashflows with greater confidence.

Parallel changes under the revised Renewable Energy Directive (RED III) reinforce the commercial signal. RED III, passed into German national law in early 2024 and now being transposed across the EU, raises the union-wide renewable energy target to 29% and tightens sustainability criteria for biofuels and synthetic fuels alike. Crucially, it introduces a 42% sub-target for renewable hydrogen in industry by 2030 and a 1% mandate for renewable fuels in maritime transport by the same year, broadening the addressable market for CO2-utilisation technologies beyond aviation.

Price Discovery and Demand Signals Still Evolving

Despite the regulatory tailwind, commercial viability hinges on closing the cost gap between fossil jet fuel and synthetic alternatives. Industry estimates place current e-kerosene production costs several multiples above conventional kerosene, driven by high electrolyser capital expenditure, renewable electricity prices and CO2 capture expenses. AI-driven price forecasting models are beginning to integrate these variables—tracking renewable power curves, carbon credit markets and electrolyser learning rates—to offer offtake counterparties better visibility on future e-fuel pricing, though the models remain sensitive to policy volatility and technology scale-up assumptions.

Investor appetite is climbing nonetheless. Offtake agreements signed in 2023 and early 2024 by airlines and fuel blenders signal willingness to lock in future volumes at premium prices, de-risking first-mover projects. The blend trajectory’s step changes—2% in 2025, 6% in 2030, 20% in 2035—create discrete investment windows, and developers report that clarity on CO2 sourcing (whether biogenic, direct air capture or industrial point sources) is now as critical to project finance as electrolyser efficiency.

Outlook: From Compliance to Commodity

As RED III and ReFuelEU become operational across member states, the CO2-utilisation value chain is transitioning from pilot scale to industrial planning. Factsheets published by Germany’s NOW GmbH in late 2024 outline how national implementation will interact with EU-wide targets, helping developers navigate double-counting rules and greenhouse-gas accounting methodologies. Market participants expect the next wave of final investment decisions to emerge in 2025 and 2026, particularly for integrated facilities combining renewable power, electrolysis, CO2 capture and Fischer-Tropsch or methanol synthesis. The challenge will be moving from compliance-driven niche supply to a liquid, price-competitive commodity market—a journey that hinges as much on capital deployment and infrastructure build-out as on continued regulatory certainty.
