Hydrogen-Powered Aviation with Beyond Aero

My Climate Journey

Eloa Guillotin is the Co-founder and CEO of Beyond Aero.

The topic of aviation emissions is complex. Flying is in many ways a crucial part of our global society, and although COVID lockdowns temporarily reduced frequent flying, the reliance on air travel in modern society is indisputable.

Aviation accounts for over 2% of global emissions. Lithium-ion batteries are heavy, which doesn't really pair well with flight. Sustainable aviation fuel is one potential solution and has promise as a drop in replacement for kerosene. But what about hydrogen?

Beyond Aero, under Eloa's leadership, is exploring hydrogen as a fuel source for small business or private jets. This episode dives into the potential of hydrogen for this aircraft category, France's commitment to hydrogen aviation, how Beyond Aero has designed its solution and how Eloa sees the market evolving.
