Hydrogen. 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 cant 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 cant have any passengers in. This is the challenge faced by zeroavia, one of several companies working to make hydrogen powered flight a reality. They retrofit existing planes with hydrogen engines. The company had several successful test flights with this plane last year
Some harmful emissions. Then theres electric. But although batteries are getting far more efficient, the size that youd need to power a passengerjet would be way too heavy. And theres one potential solution thats getting people really excited hydrogen. Hydrogen fuel cells combine Hydrogen And Oxygen to create a flow of electrons around a circuit to power a motor.

One startup thinks it has a solution for both sides. Chicago-based Celadyne has developed a nanoparticle coating that can be applied to existing fuel cell and electrolyzer membranes. The material could drastically improve the durability of existing fuel cell designs while also improving the efficiency of hydrogen production by 15% to 20%, said Gary Ong, the company’s founder and CEO.
