Batteries are more efficient in personal transport and farm equipment, than any H2 fuel cell. Also easier to re-fuel and maintain. Claims have been made about trains and heavy trucking, but so far maintenance costs have made them far more expensive than their battery counterparts.

Combusting H2 means all of the headaches of ICE engines, greater inefficiency than fuel cells/batteries, plus lots of brand new infrastructure costs.

Steel smelting is a definite yes.

By virtue of the second law of thermodyamics, hydrogen is an extremely dirty fuel. NNadir Friday #1

It's also the most abundent element of the universe BumRushDaShow Friday #2

Yes, but on earth it is chemically bound. Looking at it... NNadir Friday #3

Hydrogen is not a "form of energy", it is an energy storage medium... Think. Again. Friday #5

Hydrogen is the most abundant element in the universe GoreWon2000 Friday #8

Yes, we need to make some very big progress building out non-CO2 emitting electrical production. Think. Again. Friday #10

Simple math Miguelito Loveless Saturday #16

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

Which is still less than the energy lost by our current long distance delivery systems... Think. Again. Saturday #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 Saturday #24

Yes, the Hydrogen would not replace batteries... Think. Again. Saturday #25

The problem is Miguelito Loveless Sunday #34

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

That doesn't alter the fact Miguelito Loveless Sunday #44

Correct, directly powering your home from solar makes the most sense... Think. Again. Sunday #45

To me, marine and flight uses Miguelito Loveless Yesterday #51

Yes, and other uses where easily transportable fuel for combustion or on-site electric generation is needed. Think. Again. Yesterday #54

The environmental impact for lithium-ion Miguelito Loveless Sunday #31

Yes, and H2 can be used when weight and volume are considerations... Think. Again. Sunday #40

So far, Miguelito Loveless Sunday #46

Yes, passenger vehicles are better for batteries... Think. Again. Yesterday #49

My losses are much lower Miguelito Loveless Sunday #29

Yes, no one is suggesting H2 should replace batteries, or any other form of energy storage. Think. Again. Sunday #33

But, in using H2 for power Miguelito Loveless Sunday #39

Yes, and in situations where batteries are not viable due to weight or volume or non-existent power grid lines... Think. Again. Sunday #43

It doesn't make much sense does it madville Saturday #20

A loss of energy also occurs when it is transferred into batteries... Think. Again. Saturday #22

It must be stored either in liquid form Miguelito Loveless Sunday #28

Hydrogen containment tanks are made of materials that are impervious to embrittlement.... Think. Again. Sunday #32

The tanks are Miguelito Loveless Sunday #36

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

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

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

The issue is not flammability Miguelito Loveless Sunday #38

Precisely. Miguelito Loveless Sunday #27

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

True, Miguelito Loveless Sunday #26

Yes, but Lithium is not infinite nor renewable, while Hydrogen basically is.... Think. Again. Sunday #30

Lithium can be recycled from batteries Miguelito Loveless Sunday #35

Yes, with additional energy costs. Think. Again. Sunday #41

The additional energy cost is far lower Miguelito Loveless Yesterday #47

The Hydrogen economy infrastructure would be a cost of doing business.... Think. Again. Yesterday #52
