There is a place for #hydrogen. But blindly applying it everywhere turns it into a solution looking for a problem.

"According to the Renewable Energy Institute (REI), a Japanese environmental think tank, this push to use hydrogen in every conceivable energy sector is actually doing more harm than good. "

Everybody knows - I hope everybody knows - that fully two thirds of the energy you pour into the gasoline / diesel tank of your ICE car gets lost as heat. It's like buying three pounds of vegetables and immediately throwing out two before you start to cook with the remaining pound.

Turns, out, #hydrogen cars have the same inefficiency: 34% - 37%.

Battery e-cars have a 87% efficiency. The same solar field can power nearly three times more EVs than hydrogen cars.

@martinvermeer @CelloMomOnCars
And for the foreseeable future the H2 you are burning ( or fuel-celling) has taken between 11 and 13kg of CO2 emissions to produce.

So the full system efficiency of hydrogen at the moment makes it one of the worst possible fuels around.

Future engineering developments and delivery of genuine green ( renewable generated) H2 will help but it has a loooong way to go before it can compete with battery electric in terms of full system energy efficiency.

@helvick @martinvermeer

Yes, and meanwhile we need all the clean energy we can generate to run our heat pumps, our cooking stoves, our battery electric cars. The speed of the energy transition is important too.

@CelloMomOnCars @helvick @martinvermeer And there is no possibility of that happening without energy storage. And energy storage at the scale needed is impossible unless #hydrogen is used. Which means that hydrogen is fundamental to green energy.

In reality, anti-hydrogen people are at best clueless, at worse actively against progress.

So, @helvick @martinvermeer

You do realise that this @Hypx is paid to hype hydrogen, right?

It's now resorting to the equivalent of advertising toothpaste by saying: " You stupid a**hole, don't you SEE that my toothpaste is the best?"
