Sustainability In The Air

In this episode, we talk to Amy Hebert, Chair of the Board and CEO at Arcadia eFuels, who discusses the rapidly growing field of sustainable aviation fuel (SAF), with a focus on e-fuels. eFuels are produced with electricity from renewable sources, water and CO2 and are a sustainable alternative to fossil fuels. Hebert discusses her entry into the field, driven by the untapped potential for carbon-neutral fuels despite existing technologies like Gas to Liquids and green hydrogen electrolysers. Arcadia, her company, aims for rapid market entry and large-scale e-fuel production, targeting significant reductions in CO2 emissions. She highlights challenges in securing long-term offtake agreements and the evolving understanding of e-fuels in the market. Hebert also acknowledges the current resource intensity of e-fuels and the high costs of SAF production, emphasising the need for smaller-scale projects and technological advancements. She shares that Arcadia has not yet started producing SAF, with production expected to begin around late 2026 or early 2027. The conversation covers the importance of securing long-term commitments for green hydrogen, engaging with potential customers, and exploring innovative financing solutions. Amy's vision is to enable airlines to use 100% eSAF, facilitating responsible and cost-effective air travel.If you LOVED this episode you’ll also love the conversation we had with Gene Gebolys, President and CEO at World Energy, the world’s first producer of sustainable aviation fuel (SAF) that has been in the business of renewable fuels for over 25 years.
