UK Government to aid hydrogen aircraft development with £3m ZEFI fund
The UK Government has today (June 30) unveiled the launch of a first round £3m ($4m) Zero Emission Flight Infrastructure (ZEFI) competition. Keep up to date through me at the Hydrogen Aviation https://bit.ly/32dolZb Professionals Group

Speaking of electric aircraft, this UK project to convert a 9-passenger twin-engine propeller plane to battery-hybrid just shifted to hydrogen fuel cell power! See here or here.
They are expecting the range to plummet compared to the standard gas powered version: to 100-135nm from 639-728nm (plus 45 min reserves), but they think some of their customers can use that. Note that propeller airplanes have a very serious noise problem, but they do get good range and fly below cloud-top level (iirc, above the clouds, water vapor from engine exhaust counts as a human-caused greenhouse gas whereas at low altitudes, water vapor is a normal part of air).
Note that the range problem with hydrogen is caused by the very poor density (energy/volume), and the heavy tanks which are required for the high pressure of gaseous H2. If ammonia were used instead, energy/mass would be the limiting factor; ammonia has 43% of the energy mass density of gasoline, so we'd expect the range to be over 280 miles.
Ammonia is a better fuel than H2, in many applications, including aviation; it just needs more grass-roots support.
