What is XFuel anyway? 🚀🌳⛽

Our mission is to decarbonise the transportation industry, and we devote our technology, time and talent to advancing the transition to sustainable low-carbon fuels.

For the world to reach net-zero, we urgently need sustainable liquid fuel replacements now. Over the last 10 years, XFuel has developed and patented technologies to produce sustainable low-carbon road, marine and aviation fuels only from wastes of biogenic and non-biogenic origin.

Our road and marine fuel is a drop-in replacement to fossil fuels, not requiring blending, engine modifications or infrastructure investment in energy distribution or storage. Our project capital requirements are up to 5x lower, and our production costs are comparable or lower than fossil fuel market prices. We have a pilot plant in Mallorca, Spain which demonstrates our technologies producing up to 1mil litres of fuel, and have a modular approach to scaling up production in our commercial projects.

XFuel’s goal is to build, own and operate plants globally, becoming the full-stack sustainable fuel company for the 21st century. We are rising to the challenge of decarbonising the transportation industry and we are looking for passionate people to help us get there. We hope to find people that reflect our mission, vision, values and drive.
