25. Yes, the Hydrogen would not replace batteries...

...I don't think it's an either/or situation, but the lighter weight and better energy retention of H2 compared to batteries would make H2 as an energy storage medium more transportable and it can also be usable in combustion engines when those designs are preferable.

We are going to need every non-CO2 energy tech we have, very soon, and luckily we do have a variety of both energy production and energy storage techs to fit all the various situations, restrictions, and uses we will be dealing with.

Edit to add: I mentioned in an earlier reply that I donct consider Hydrogen made using fossil fuels in any way as a worthwhile pursuit. I believe all our H2 attention should be focussed on building out a Green H2 economy only.

Natural gas leaks are 28X as powerful as CO2.... Think. Again. Jan 3 #12

And hydrogen leaks twice as much as methane, by it's very nature as the smallest element NickB79 Jan 4 #17

And then fuel cells lose about 40%-60% of the 34kWH in the H2 converting it into electricity? /nt nmmi Jan 4 #18

Which is still less than the energy lost by our current long distance delivery systems... Think. Again. Jan 4 #23

59% is losses in the power plant itself in converting the fuel's energy to electricity at the power plant and net of nmmi Jan 4 #24

Correct, I personally believe only a Green H2 economy is worthy of pursuing.... Think. Again. Jan 5 #37

That doesn't alter the fact Miguelito Loveless Jan 5 #44

The tanks are Miguelito Loveless Jan 5 #36

Yes, they can be. And older existing lines can even be coated to be impervious. Think. Again. Jan 5 #42

That means digging up old lines and replacing them Miguelito Loveless Jan 6 #48

No, if the cost is 2 million, that's what it is, not more. Think. Again. Jan 6 #53

The issue is not flammability Miguelito Loveless Jan 5 #38

Any transfer of energy results in a loss... Think. Again. Jan 4 #21

True, Miguelito Loveless Jan 5 #26

Lithium can be recycled from batteries Miguelito Loveless Jan 5 #35

The additional energy cost is far lower Miguelito Loveless Jan 6 #47
