Hydrogen is only a "dirty fuel" when made using methane or with a "dirty" electricity source.

Green Hydrogen (which doesn't use fossil fuels at all to be produced) does not emit any CO2 at all.

By virtue of the second law of thermodyamics, hydrogen is an extremely dirty fuel. NNadir Jan 2025 #1

It's also the most abundent element of the universe BumRushDaShow Jan 2025 #2

Yes, but on earth it is chemically bound. Looking at it... NNadir Jan 2025 #3

Hydrogen is not a "form of energy", it is an energy storage medium... Think. Again. Jan 2025 #5

Hydrogen is the most abundant element in the universe GoreWon2000 Jan 2025 #8

Yes, we need to make some very big progress building out non-CO2 emitting electrical production. Think. Again. Jan 2025 #10

Except when it leaks NickB79 Jan 2025 #11

Natural gas leaks are 28X as powerful as CO2.... Think. Again. Jan 2025 #12

And hydrogen leaks twice as much as methane, by it's very nature as the smallest element NickB79 Jan 2025 #17

Simple math Miguelito Loveless Jan 2025 #16

And then fuel cells lose about 40%-60% of the 34kWH in the H2 converting it into electricity? /nt nmmi Jan 2025 #18

Which is still less than the energy lost by our current long distance delivery systems... Think. Again. Jan 2025 #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 2025 #24

Yes, the Hydrogen would not replace batteries... Think. Again. Jan 2025 #25

The problem is Miguelito Loveless Jan 2025 #34

Correct, I personally believe only a Green H2 economy is worthy of pursuing.... Think. Again. Jan 2025 #37

That doesn't alter the fact Miguelito Loveless Jan 2025 #44

Correct, directly powering your home from solar makes the most sense... Think. Again. Jan 2025 #45

Yes, and other uses where easily transportable fuel for combustion or on-site electric generation is needed. Think. Again. Jan 2025 #54

Yes, and H2 can be used when weight and volume are considerations... Think. Again. Jan 2025 #40

So far, Miguelito Loveless Jan 2025 #46

Yes, passenger vehicles are better for batteries... Think. Again. Jan 2025 #49

My losses are much lower Miguelito Loveless Jan 2025 #29

Yes, no one is suggesting H2 should replace batteries, or any other form of energy storage. Think. Again. Jan 2025 #33

But, in using H2 for power Miguelito Loveless Jan 2025 #39

Yes, and in situations where batteries are not viable due to weight or volume or non-existent power grid lines... Think. Again. Jan 2025 #43

A loss of energy also occurs when it is transferred into batteries... Think. Again. Jan 2025 #22

It must be stored either in liquid form Miguelito Loveless Jan 2025 #28

Hydrogen containment tanks are made of materials that are impervious to embrittlement.... Think. Again. Jan 2025 #32

The tanks are Miguelito Loveless Jan 2025 #36

Yes, they can be. And older existing lines can even be coated to be impervious. Think. Again. Jan 2025 #42

That means digging up old lines and replacing them Miguelito Loveless Jan 2025 #48

No, if the cost is 2 million, that's what it is, not more. Think. Again. Jan 2025 #53

The issue is not flammability Miguelito Loveless Jan 2025 #38

Precisely. Miguelito Loveless Jan 2025 #27

Any transfer of energy results in a loss... Think. Again. Jan 2025 #21

True, Miguelito Loveless Jan 2025 #26

Yes, but Lithium is not infinite nor renewable, while Hydrogen basically is.... Think. Again. Jan 2025 #30

Lithium can be recycled from batteries Miguelito Loveless Jan 2025 #35

Yes, with additional energy costs. Think. Again. Jan 2025 #41

The additional energy cost is far lower Miguelito Loveless Jan 2025 #47

The Hydrogen economy infrastructure would be a cost of doing business.... Think. Again. Jan 2025 #52
