The Allplane Podcast #79 - a critical assessment of sustainable aviation technologies, with Michael Barnard

Michael Barnard is one of the most outspoken experts in the field of renewable energy and decarbonization technologies and, as it couldn’t be otherwise, has also had a close look at the different projects that are claiming to take aviation towards the path of sustainability.

In this long and gripping conversation, Michael doesn’t mince words when talking about some of the trends and themes that are sweeping through the world of aviation, from eVTOLs to hydrogen.

Michael has also taken the bold step of publishing his forecasts about the evolution of air traffic demand all the way up to the year 2100, a prediction which diverges considerably from those made public by official industry bodies and other analysts and that he aims to revise regularly as new data comes available.

He also shares some insights about what he sees are promising areas of growth in sustainable aviation. Not for nothing he is an advisor to several startups that are developing solutions in the field of electric aviation.

Whether you agree or not with Michael’s views on the industry, what I am sure is that today’s episode won’t leave you indifferent, it may even make some uncomfortable, but will certainly provide food for thought to anyone interested in the different projects, technologies and companies that are currently trying to shape the future of aviation for decades to come.

Tune in for a rather unconventional and, straightforward chat about sustainable aviation!
