Hydrogen Fuel
« on: January 23, 2017, 10:40:47 AM »
I'd like to get a couple of different people's inputs on these questions.

Do you believe Hydrogen is a practical fuel source?
If not, do you believe it can become one?
Why or why not?

Nice homework question.
Think about generation.
Then think about storage and delivery.
Let's not mention safety
Development Chemists do it on Scale, Research Chemists just do it!

Hydrogen fuel, you mean, for rockets? Definitely yes, for >50 years, and irreplaceable.

Oh, for other uses? That could prove to be one of the most expensive errors in human research, unless someone eventually finds a decent storage method (or until humans find an even more expensive error, of course). The progress of lithium batteries has made hydrogen less seducing in the last years.

I still see a future for hydrogen fuel: at aeroplanes. Hydrogen's energy per mass unit improves the range and flight duration. Car fuel cells are already light enough for slower aeroplanes: helicopters far better than kerosene right now, 500km/h planes easy, 1000km/h planes not quite good. Design examples there with 100kg/100kW fuel cells, the last ones with up-to-date 50kg/100kW, including my tank design for liquid hydrogen.
