Very interesting alternative to electric vehicles!!
Also avoids the well documented problems with hydrogen fuel cell systems.

Isn't hydrogen the one that goes kaboom?

The future is with giant twisted elastic bands

The point is that the hydrogen sits in a big pressurised tank nowhere near the sparky bits.

The F1 teams are actively looking into Hydrogen fuelled engines to replace petrol now. Wont happen for a while but it's where they want to go.

Good, an alternative to electricity...

Hang on, how do you make hydrogen.

With reusable and surplus energy.

One problem the grid has is uneven loads, hydrogen production can act as a variable load getting power generation into their sweet spots.

You could run wind or nuclear at a high level for the peaks but generate green hydrogen instead of ramping up and down.

Right. Free energy. Got it.

So what happens when off-peak capacity is being used for fuel production...?

Peaks in energy usage can be levelled by switching excess capacity to generating hydrogen.

Currently the grid spin up power stations to supply peaks as having excess power sent to the grid can fry it. The classic example is they spin up coal fired stations for the Eastenders/Corrie cuppa - thousands of kettles going on for tea in the interval they would use cleaner nuclear but they take too long to spin up so effectively end up as too expensive for a short burst.

It does when you make an atomic bomb out of it, but that's now considered outdated technology...
