Rather than compete with fossil fuels from the start, Stephen identified high-purity methane for lab-grown diamonds as a beachhead market—where Circularity’s product is 80–90% cheaper than incumbents while proving the core technology needed for clean liquid fuels. Stephen earned a chemistry PhD at Oxford and built deep expertise in synthetic fuels during his U.S. Air Force career, including overseeing jet fuel quality control in the Middle East and launching the Air Force’s e-fuels program. His insight: build a fuels company that doesn’t begin with fuel. Today, Circularity Fuels operates demonstration reactors in diamond facilities and is scaling toward biogas-to-SAF production using the same reactor platform. The company has raised $3M in venture funding, including from DCVC, plus $5M in grants from ARPA-E, NSF, and the California Energy Commission. MCJ is proud to be an investor.","meta_description":"Dr. Stephen Beaton is Co-founder and CEO of Circularity Fuels, which develops compact reactors that turn waste carbon streams into high-value fuels and ch…","key_points":[],"chapters":[],"topics":[],"duration_seconds":3223,"processing_state":"not_requested","actions":[{"name":"request_transcript","method":"POST","url":"https://stenobird.com/v1/public/podcasts/inevitable-16764/episodes/why-circularity-fuels-started-with-diamonds-to-scale-sustainable-jet-fuel/transcription-requests","description":"Idempotently request low-priority transcript generation for this episode."},{"name":"read_markdown","method":"GET","url":"https://stenobird.com/podcast/inevitable-16764/why-circularity-fuels-started-with-diamonds-to-scale-sustainable-jet-fuel.md","description":"Read the agent-friendly Markdown representation of this episode resource."}]}}
