"But unless my calculations are wrong — which I hope they are, by at least three orders of magnitude — if we gave up burning fossil fuels today, we would have to reduce our energy consumption overnight to 6% — six percent — of what we currently consume"

Aviation-fuel and generating capacity
I wrote in my last piece on aviation fuel that I thought that electrolysing the amount of hydrogen needed to fuel the world's jetliner fleet would use more electricity than the world's entire generating capacity, but that I would have to run the numbers. Well, now I have.

Researchers demonstrate hydrogen as a viable aviation fuel
Researchers from Swansea University are celebrating their role in a major aviation milestone following the successful completion of a four-year international program led by Rolls-Royce and easyJet to demonstrate hydrogen as a viable aviation fuel. The program has culminated in a world-first achievement: a modern aero engine running on 100% hydrogen at full takeoff power, proving the potential of hydrogen to play a transformative role in future zero-carbon aviation.

Reducing aircraft soot might not actually reduce the climate effects of contrails
Reducing aircraft soot emissions may not reduce contrail clouds, according to in-flight observations of emissions from a passenger jet with modern "lean-burn" engines, reported in Nature. Contrails from aircraft contribute to the climate-warming impacts of aviation. The findings demonstrate that more work is needed to understand and reduce the climate impact of jet engine emissions.

American Airlines and Google say AI helped airplanes reduce contrails that trap heat
American Airlines and Google said Thursday that they significantly reduced the climate impact of some of the airline's flights using an AI-based forecasting tool to help prevent contrails.
