The main reason the hydrogen hype is in overdrive: Big Oil n Gas wants to make money converting fossil gas into hydrogen.

"Before looking at why legacy #automotive companies, resource tycoons and the politicians that represent them, have been such huge advocates for hydrogen-powered vehicles, it’s important to firstly outline why #hydrogen cars are so fundamentally flawed and will never come close to competing with #battery electric vehicles."

The madness of Big Auto's push for hydrogen-powered cars

The battle between hydrogen and electric vehicles has been more about preserving entrenched energy monopolies and less about science. The war is now over but some continue to push the hydrogen pipe dream.

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. "

Japan Tried to Build a Hydrogen Society. It Backfired Spectacularly.

Seemed like a good idea at the time.

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.

@CelloMomOnCars Yep, the moment you burn stuff, you're losing... although those fuel cells aren't too good either at 60% efficiency.

@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 @CelloMomOnCars For the foreseeable future, EVs are unsustainable and enormously environmentally destructive. Nor is the grid zero emissions either.

This is a common double standard: #hydrogen cannot be accepted because it is not yet green. But dirty electricity and batteries are fully acceptable for now. This is the delusion that #EV companies want you to believe.
