it's nearly impossible to store it as a liquid because of the pressures involve

It's maintaining the temperature that is challenging with LH2

Hydrogen got the Apollo missions to the moon and back. You aren't suggesting that, in 2019- 50 years later- H2 cannot be stored? Guess what- we have carbon fibre now. Even better than whatever they used 50 years ago.

fact that it likes to leak through almost anything at those pressures

Mike Strizki, one of the top H2 pioneers in the world, has stored H2 made from excess solar energy in old propane tanks since around 2005. You can see his system and the tanks in videos at his website - http://hydrogenhouseproject.org

It really doesn't matter what anyone thinks about this matter, China is moving to literally own the entire hydrogen industry as you read this. They can get things done- they are building Hydrogen Cities and Hydrogen Corridors now. China's Father of Battery EV's has called for a pivot to H2.
