Flying without emissions: how hydrogen is greening aviation

A 20-seater plane powered by a zero-emissions hydrogen fuel cell engine just made its first test flight. We talk to the company behind it, that believes all planes can be made zero-emissions.

In a recent test flight, ZeroAvia, an engine builder, made history by flying a 20-seater aircraft completely powered by green hydrogen, a zero-emissions fuel. The breakthrough test, which is the largest aircraft to ever be flown using hydrogen power, is a promising step towards a zero-emissions future for the aviation industry.

In this episode of Radio Davos, Val Miftakhov, the CEO of ZeroAvia, talks about the company's mission to develop zero-emission planes, the potential for commercial airlines to adopt this technology, and the role of customer demand and government regulation in achieving a more sustainable aviation industry. The episode also explores the challenges and opportunities in transitioning to zero-emission aviation.

However, persistently high inflation, and uncertainty related to Russia’s invasion of Ukraine and other conflicts, pose significant threats to the industry’s continued recovery.
