Biden administration adds exemptions into new climate rules for hydrogen energy [View all] BumRushDaShow Jan 3 OP

By virtue of the second law of thermodyamics, hydrogen is an extremely dirty fuel. NNadir Jan 3 #1

It's also the most abundent element of the universe BumRushDaShow Jan 3 #2

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

Hydrogen is not a "form of energy", it is an energy storage medium... Think. Again. Jan 3 #5

Hydrogen is the most abundant element in the universe GoreWon2000 Jan 3 #8

Yes, we need to make some very big progress building out non-CO2 emitting electrical production. Think. Again. Jan 3 #10

Well... BumRushDaShow Jan 3 #6

His background is in chemistry. He's in the pharmaceutical industry. His journal is worth a scroll nmmi Jan 3 #14

As explained in the article... Think. Again. Jan 3 #4

Except when it leaks NickB79 Jan 3 #11

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

A small mistake you made... Think. Again. Jan 4 #19

Green hydrogen is the future GoreWon2000 Jan 3 #7

When will the scam that is the "hydrogen economy" Miguelito Loveless Jan 3 #13

If you're Anti-Hydrogen, whatever you do - DO NOT LOOK AT CHINA or India Caribbeans Jan 4 #15

Simple math Miguelito Loveless Jan 4 #16

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

Yes, the Hydrogen would not replace batteries... Think. Again. Jan 4 #25

The problem is Miguelito Loveless Jan 5 #34

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

Correct, directly powering your home from solar makes the most sense... Think. Again. Jan 5 #45

To me, marine and flight uses Miguelito Loveless Jan 6 #51

Yes, and other uses where easily transportable fuel for combustion or on-site electric generation is needed. Think. Again. Jan 6 #54

The environmental impact for lithium-ion Miguelito Loveless Jan 5 #31

Yes, and H2 can be used when weight and volume are considerations... Think. Again. Jan 5 #40

So far, Miguelito Loveless Jan 5 #46

Yes, passenger vehicles are better for batteries... Think. Again. Jan 6 #49

My losses are much lower Miguelito Loveless Jan 5 #29

Yes, no one is suggesting H2 should replace batteries, or any other form of energy storage. Think. Again. Jan 5 #33

But, in using H2 for power Miguelito Loveless Jan 5 #39

Yes, and in situations where batteries are not viable due to weight or volume or non-existent power grid lines... Think. Again. Jan 5 #43

By very expensive tanker trucks Miguelito Loveless Jan 6 #50

It doesn't make much sense does it madville Jan 4 #20

A loss of energy also occurs when it is transferred into batteries... Think. Again. Jan 4 #22

It must be stored either in liquid form Miguelito Loveless Jan 5 #28

Hydrogen containment tanks are made of materials that are impervious to embrittlement.... Think. Again. Jan 5 #32

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

Precisely. Miguelito Loveless Jan 5 #27

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

True, Miguelito Loveless Jan 5 #26

Yes, but Lithium is not infinite nor renewable, while Hydrogen basically is.... Think. Again. Jan 5 #30

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

Yes, with additional energy costs. Think. Again. Jan 5 #41

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

The Hydrogen economy infrastructure would be a cost of doing business.... Think. Again. Jan 6 #52
