In reply to the discussion: Biden administration adds exemptions into new climate rules for hydrogen energy [View all]Miguelito Loveless
(4,728 posts)39. But, in using H2 for power
the most common way is to convert electricity to H2, store it, then convert back to electricity on demand. That is essentially using H2 as a storage medium, i.e., a battery. Yes, you can burn H2 to make heat, or in a redesigned combustion engine, but you are now back at square one in terms of efficiency, with higher cost, than if you had simply used the electricity to directly charge a chemical battery or run a heat pump.

And hydrogen leaks twice as much as methane, by it's very nature as the smallest element

And then fuel cells lose about 40%-60% of the 34kWH in the H2 converting it into electricity? /nt

Which is still less than the energy lost by our current long distance delivery systems...

59% is losses in the power plant itself in converting the fuel's energy to electricity at the power plant and net of

Correct, I personally believe only a Green H2 economy is worthy of pursuing....

Yes, and other uses where easily transportable fuel for combustion or on-site electric generation is needed.

Yes, no one is suggesting H2 should replace batteries, or any other form of energy storage.
Think. Again.

Yes, and in situations where batteries are not viable due to weight or volume or non-existent power grid lines...

Hydrogen containment tanks are made of materials that are impervious to embrittlement....

Yes, they can be. And older existing lines can even be coated to be impervious.

Yes, but Lithium is not infinite nor renewable, while Hydrogen basically is....

The Hydrogen economy infrastructure would be a cost of doing business....
