Originally published at: Beyond Aero Concludes Hydrogen Aircraft Design Review
The company said it is targeting certification under transport-category standards for its hydrogen jet program.
To my mind, this seems to be a significant improvement over batteries. Refilling is much faster than recharging and the energy density of hydrogen is much higher than batteries. Of course, a tank capable of safely carrying a gas pressurized to 700 bar is going to be heavy (eating into the energy density calculation), there are probably safety concerns around hydrogens transparent flame, and I’m sure that somebody will share the multitude of issues I’ve missed. Regardless, even with the well earned skepticism that comes from decades of broken promises in aviation, this brings me a little happiness.
