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.

If manufactures weren't so obsessed with SPEED in EVs the motors can deliver more mileage. 1000 horsepower is obscene. Most gas cars in the size range are 175 to 225 HP.

If manufacturers weren't so obsessed with PROFIT the world would be a better place.

Lithium could be spread over a lot more EVs.
Walkers and bikers wouldn't be bullied - and killed - by SUVs.
We would all get fewer speeding tickets.

A long time ago I figured out - for fun - how much #horsepower you need for a medium-sized car to cruise the nation's highways.
Spoiler: 76 HP.

How much horsepower do you <em>need</em>?

One very important item in the "Performance Specification" page of any car is the power of the engine. CelloMom explores what exactly you ...

@CelloMomOnCars That seems quite generous.
We haven't had a car for some years now but when I first met my wife she owned one with a 41 HP engine. We lived in the UK and it took us around much of the country, including hilly areas, without any problems caused by lack of power. Acceleration was fairly gradual but it was definitely capable of exceeding the 70 mph speed limit (though not uphill).

The 76HP is for a "medium" (for the US) car like a Toyota Camry to go up a 6% grade at 65mph.

More than 150 HP is a boys' dream implanted by the car industry.

Your story reminds me, my husband has stories of his grandfather taking his car (ancient in the 1970s) up the hill at Newton Poppleford (near Sidmouth) and rather literally going backward as he shifted gears -- I'm sure that car had less than 41HP!
