Hydrogen cars *are* electric cars, they just use a much less efficient way of getting energy from one place to another than a battery.
Yes thanks for stating the obvious.

As I’m sure you know R+D can lead to potential opportunities and uses outside of the original scope of R+D, so if a government or private company is willing to use road vehicles as a test bed for potential future technology, again I see no downside to that.

Hydrogen certainly has some future esp in liquid storage form for energy storage and heavy use.

I just think it's poor tech for cars and not likely to get much better at a time when full battery cars are improving vastly.

For people actually open-minded about hydrogen vehicle technology rather than those that just endlessly criticise it, you may find it interesting to look at the Chinese company Grove Hydrogen Automotive (www.grove-auto.com). It is great to see what they have achieved so far.

A poor website...

Grove Auto said:
It's the most abundant element in the universe, it weights half that of oxygen and it's loaded with energy.
Err, no...

Grove Auto said:
As little as 5kg of Hydrogen can power our some of our cars for 1,000 kms:
The Toyota Mirai will do 500km on 5kg and is the most efficient HFC on the market.

We have one of the highest compositions of Carbon Fibre seen in a volume production car.
They must have sold loads! Or none...

At Grove we value your safety as much as we do our planet, Granite like all Grove cars achieves a 5 star CNCAP Rating.
And so safe! Oh wait, that's China NCAP...

Small steps but in the right direction.

An interesting step forward, and also good to read that hydrogen-ready boilers would only need very minor modifications to be able to convert to complete hydrogen.

I disagree that heat pumps must have highly insulated homes, but that's just a small point.

It still doesn't address the terrible efficiency of cracking hydrogen in the first place.

Hydrogen is not a fuel it's an energy store, so the energy has to come from somewhere else. Why not run the boilers directly from the electricity used to crack hydrogen? The only advantage is the ability to store excess night electricity, but that's no different to other thermal or electrical stores.

Seems to be some progress being made in the storage aspect at least, the article does mention how the costs and efficiencies in the production of Hydrogen are coming down as the technology improves (same as BEV and ICE cars before them?).

It seems to have some place in our post fossil fuel world, if no for personal transport then commercial?

I see that scheme is being promoted by a gas supplier. What a shock. Smells of desperation.

Starting to see viable heat exchanger boiler replacements at decent prices now. Gas companies should be as worried about the long term as petrol/diesel suppliers.
