    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.

    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.

    CPKC $CP hydrogen fuel cell locomotive & gaseous hydrogen #GH2 tender enter mainline service, carrying Glencore Elk Valley metallurgical coal.

    N America needs #hydrogen #fuelcell trains, as only 1% of track is electrified. Electrification costs USD$1-$8MM/mi.
