#H2History
B-57 airplane with one engine modified by NACA-Lewis to run on liquid hydrogen fuel. Helium was used to pressurize the H2 tank.
First flight: 23Dec1956.

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.

#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).

Today is the anniversary of the #Apollo11 Moon landing!
At Kennedy #Space Center’s Visitor Complex, it’s possible to visit the #Apollo / Saturn V Center, where a #SaturnV #rocket is on display, with its stages separated.
These are the 5 J-2 engines that powered the S-II stage that was the second stage on the Saturn V.
They burned liquid hydrogen (#LH2) and liquid oxygen (#LOX). This high-energy combination of propellants made it much easier for the United States to build a successful #Moon mission, whereas the Soviets were forced to stick with hypergolic fuels or kerosene, making lunar missions impractical.
