In aviation, there’s a crowd of low-carbon technologies vying for a slice of the market. On one hand, the long-haul portion of the market will likely rely on sustainable aviation fuels (SAFs) which still emit greenhouse gasses but could be offset to net-zero. On the other hand, there’s a big share of air traffic that could go completely zero-emissions with the help of batteries and hydrogen. So how soon could you book a ticket on a zero-emissions flight? And what routes are possible? In this episode, Shayle talks with Jayant Mukhopadhaya, a researcher at the International Council on Clean Transportation (ICCT). Jayant recently authored two reports on electric aircraft and hydrogen aircraft. Shayle and Jayant dig in on some tough questions: Can electric aircraft take incremental steps into the market given the limitations of current battery energy densities? Or do they need a technology breakthrough? How do hydrogen fuel cell, compressed hydrogen combustion, and liquid hydrogen combustion compare? How do airports need to prepare for hydrogen fueling?
