Booking your first zero-emissions flight

What this episode covers

Jayant Mukhopadhaya, a researcher at the International Council on Clean Transportation (ICCT), explains the viability of zero-emissions aviation, noting that battery electric aircraft are limited to short regional routes due to current energy density, requiring a doubling of battery capacity to reach viable ranges. He contrasts this with hydrogen technologies, where fuel cells serve smaller aircraft while liquid hydrogen combustion targets larger single-aisle planes, though both face significant infrastructure hurdles. The discussion highlights that electric aircraft offer superior energy efficiency but cannot replace long-haul flights, which will likely rely on sustainable aviation fuels (SAFs) to achieve net-zero emissions by 2050.
