Hydrogen fuel cells combine hydrogen and oxygen to create a flow of electrons around a circuit to power a motor. and as we all know, hydrogen plus oxygen equals h20. the problem is... we can't do much about the fundamental properties of hydrogen. volumetrically, we need to compress it to get sort of in the ballpark of not quite a third of the efficiency of fuels that we use. that means that we need often very large, very heavy tanks, because they need very thick walls to deal with the incredibly high pressures we need them at. what you end up with is an aeroplane that can't have any passengers...

Than conventionaljet fuel, but backers of hydrogen planes believe it will eventually become cheaper than traditional flight. zeroavia isn't the only company racing to reimagine air travel, though. aerospace giants like airbus and boeing are also developing hydrogen planes. but there are still questions over how sustainable they'll actually be. we're going to be using some fairly exotic materials that are very energy intensive to arrive at. what energy are you using to build the fuel cell? what materials are you using? how much energy are we sinking into this technology to get something out? ze...

ZeroAvia's UK managing director talks powering on in spite of naysayers, the role of 'clean sky thinking', and being asked 'what about the Hindenburg?'
