1) 2nd law/Carnot efficiency for internal combustion engines or gas turbines does not apply to electrochemistry. Hydrogen fuel cells often "toss away" less than 1/2, not 3/4 of heat engines' +embodied energy".
2) 700Bar gaseous #H2 storage is good for many end uses; liquified #LH2 is a special case.
3) Underground #GH2 storage similar to current seasonal natgas case enables seasonal energy storage & dunkelflaute mitigation.
Hey peeps, any comment on why the 8MW Calistoga hydrogen fuel cell microgrid doesn't include auto-bumpless transfer for grid to islanded microgrid mode if the T&D line goes down?
FCW appears to say it only works on a PSPS event signal from PG&E!
Hey Canary Media, if an 8MW liquid-hydrogen-fueled Plug Power fuel cell can perform bumpless transfer from grid to islanded microgrid mode↙️ in Calistoga, CA, it would be technical malpractice to not have spent a few extra dollars & program black-start capability into the system!↘️ All the necessary hardware is already there!
Please verify that your statement is true.

I could have saved SwRI’s client NYSEARCH a lot of money by showing them this 1968 NASA report⬇️: solubility of hydrogen in liquified natural gas (methane) is well below 1% (≈0.06% v/v).
So it is basically impossible to store economically useful amounts of #hydrogen in #LNG.

Researchers at the University of Tsukuba have reported on the structure and light energy transfer efficiency of a protein complex crucial to the photosynthesis of purple sulfur bacteria thriving in high-salt, high-alkaline environments. Cryo-electron microscopy observation and computer analysis revealed that this unique protein complex significantly enhances energy conversion ability. The findings are published in the journal Nature Communications.

#Battery based #EV are a fad, scam and duds. Absolute cul-de-sac stopping us from implementing real solutions to get away from hydrocarbon-based ICEs.
We could absolutely switch/transition to #LH2 ICEs from diesel ICE tech (higher press manifolds than #gasoline), and do that for a long while, before we get to some Clarkes-3rd-Law solution (lol).
