Aviation technology startup Metafuels announced that it has raised $24 million in a Series A funding round, with proceeds aimed at accelerating the commercialization of its synthetic sustainable aviation fuel (e-SAF) technology, which converts green methanol into jet fuel.
Fuel accounts for the vast majority of the aviation sector’s emissions. Generally produced from sustainable resources, like waste oils and agricultural residues, sustainable aviation fuel (SAF) is seen as one of the key tools to help decarbonize the aviation industry in the near- to medium-term. According to a recent report by the International Air Transport Association (IATA), however, while SAF production nearly doubled in 2025, it still accounted for just 0.6% of airlines’ total fuel consumption. Efforts to meaningfully increase the production of SAF face barriers including high initial costs and feedstock challenges.
Founded in 2021 and based in Zurich, Metafuels develops technology to produce synthetic jet fuel from captured CO₂ and green hydrogen, with the goal of making e-SAF cost-competitive with conventional jet fuel over the long term.
In addition to providing a more cost effective process for producing SAF, Metafuels noted that its technology also addresses concerns related to constrained supply of waste oil and fats that challenge other production pathways, with e-fuels not limited by feedstock availability.
The company said the new capital will support the development of its methanol-to-jet demonstration plant in Switzerland and support plans for a commercial-scale e-SAF facility at the Port of Rotterdam, which will produce its “aerobrew” e-SAF product, marking the initial deployment of its technology at industrial scale.
Saurabh Kapoor, Chief Executive Officer of Metafuels, said:
“If sustainable aviation fuel is to become a true alternative to fossil jet fuel, it has to work at industrial scale and competitive cost. Methanol-to-jet makes that possible. With aerobrew, we are building a technology that allows airlines to decarbonize without changing how they operate, with the potential to reshape the future of flight.”
The Series A round was led by UVC Partners, with participation from existing investors including Energy Impact Partners (EIP), Contrarian Ventures, RockCreek, Verve Ventures, and Fortescue Ventures.
Johannes von Borries, Managing Partner at UVC Partners, said:
“This investment supports the implementation of a unique technology with the potential to scale and drive down the cost of SAF to the point where it becomes an economical alternative to fossil fuels.”
