Metafuels, a Swiss startup based in Würenlingen, is at the forefront of developing sustainable aviation fuels (SAFs) using e-methanol at the Paul Scherrer Institute. By utilizing methanol synthesis instead of the conventional Fischer-Tropsch process, Metafuels aims to produce e-SAFs more efficiently and cost-effectively. The startup's pilot project and demonstration plant have shown promising results, with projections suggesting significant cost savings and efficiency gains compared to traditional methods. With a diverse team and collaborations with the Paul Scherrer Institute, Metafuels is deploying advanced technologies like AspenTech's digital twin to enhance its production process and refine its e-SAF product, Aerobrew. Metafuels has successfully raised $22 million in funding, with plans to establish e-SAF facilities in Denmark and The Netherlands. The startup is actively engaging in early offtake conversations and forming partnerships with airlines, fuel suppliers, airports, and corporate travelers. Metafuels also intends to commercialize its technology through licensing agreements, offering opportunities for global market expansion. Overall, the innovative approach of Metafuels in producing e-SAFs through methanol synthesis showcases a positive sentiment towards sustainable aviation and technological advancement in the industry.
