On the Catalyst with Shayle Kann podcast this week:
There’s a crowd of low-carbon technologies vying for a slice of the aviation market. On one hand, the long-haul portion of the market will likely rely on sustainable aviation fuels (SAFs), which still emit greenhouse gases but could be offset to achieve 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 will you be able to 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. Jayant recently authored two reports, one on electric aircraft and one on 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 cells, compressed hydrogen combustion and liquid hydrogen combustion compare?
- How do airports need to prepare for hydrogen fueling? Hint: Terminal-sized upgrades.
