Low-Carbon Aviation Energy – Aviation energy solutions reducing CO₂ emissions.

Low-carbon aviation energy in Europe encompasses a range of solutions aimed at reducing the sector's significant greenhouse gas emissions, extending beyond just liquid sustainable aviation fuels (SAF). While SAF is the primary and most immediate tool for decarbonization, particularly for medium and long-haul flights, the broader low-carbon energy portfolio also includes emerging and disruptive technologies like green hydrogen and battery-electric propulsion.

The immediate focus is on SAF because it is a "drop-in" fuel, meaning it is compatible with existing aircraft engines and airport refueling infrastructure with minimal to no modification, enabling immediate CO

  reductions. Pathways like HEFA (from used cooking oil) and eventually PtL (Power-to-Liquid) are central to this strategy. PtL, in particular, relies heavily on the large-scale, low-cost supply of renewable electricity and green hydrogen—both key forms of low-carbon energy in their own right—positioning them as foundational to the future of liquid SAF production.

Beyond liquid fuels, significant research and innovation effort is directed toward hydrogen-powered aircraft and electric aircraft. Hydrogen energy is being explored for future regional and short-haul flights, supported by EU-funded initiatives like Clean Aviation. While battery-electric propulsion is largely confined to small, short-range aircraft (like eVTOLs), it represents another crucial pillar in the long-term, low-carbon energy mix. The transition to truly low-carbon aviation energy requires a coordinated strategy that not only scales up SAF production but also simultaneously develops the necessary infrastructure, regulatory framework, and aircraft technology for these more radical, zero-emission propulsion systems.
