Why Surf Air Mobility sees Hawaii as the ideal proving ground for electric aviation

2026-10-2955:30

In this episode, we speak with Louis Saint-Cyr, President of Airlines at Surf Air Mobility, to explore how electric aircraft could transform regional aviation. He discusses: Why electrification over SAF: SAF, Saint-Cyr argues, is geared towards larger aircraft and long-haul flying. For a nine-seat island operator, electric aircraft tackle three things at once: carbon, operating cost, and alignment with Hawaii's legislated path to 100% renewable electricity by 2045.Hawaii as the ideal proving ...

Why VAERIDION believes a 100% electric nine-seater aircraft can beat every alternative on cost

2026-10-1543:55

In this episode, we speak with Ivor van Dartel, CEO and co-founder of VAERIDION, which is developing the Microliner, a 100% electric, nine-passenger fixed-wing aircraft. He discusses: Why VAERIDION chose electric aircraft: Despite leading hybrid-electric work at Airbus, Ivor argues that hybrids carry twice the system complexity and still burn fuel. The Microliner has range limits, but within them he believes it will be unbeatable on unit economics, just as electrification has won on cost in r...

Why Gevo believes low-carbon ethanol and carbon capture are the foundation for scaling alcohol-to-jet SAF

2026-09-1750:03

In this episode, we speak with Paul Bloom, CEO of Gevo, who shares how low-carbon fuels, carbon capture, and technology are coming together to accelerate aviation’s path to net zero. He discusses: Why Gevo stepped away from the DOE loan guarantee: The DOE loan guarantee was always one of several potential financing options for Gevo. When enhanced oil recovery (EOR) for Gevo’s CO2 co-product became a requirement, the lack of oil and gas infrastructure in North Dakota made it difficult to secur...
