That's terrific! The energy content in H2 beats anything except nuclear
power, and wouldn't it be great to fly a 72 ton glider around with unlimited launch and retrieve capability? But one statement in the article has me perplexed: "Current hydrogen extraction is highly energy intensive, so ways to harvest “green hydrogen” using water electrolysis are being explored." I believe that it takes more energy to extract the hydrogen from water than is realized by burning the hydrogen. I have no idea of the energy cost to liquefy and distill hydrogen. Can anybody shed some light on that? I can see giant smoke stacks spewing sooty black smoke into the air due to burning coal to generate the electricity to compress the air to harvest the hydrogen. Well... Maybe not. Perhaps covering Europe with wind mills to make the electricity and using sailing ships to deliver the H2 around the world. Credit to Dr. Seuss and Rube Goldberg for the inspiration.
