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.

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.

@ScribblersEmporium

What "storage problem"?

Cost-effective gaseous #GH2, liquid #LH2 and cryo-compressed hydrogen #CCH2 storage methods are available for moderate amounts of H2.

Several avenues of underground storage are good for seasonal storage (think summer - winter) of massive quantities of hydrogen.

The working groups cover the GH2related topics: production, transport and infrastructure, market stimulation, cross-cutting issues. Additionally, participation in scientific conferences and other events may be funded.
