Harry's not your average youTuber to get a personal flight with Lord Bamford in his helicopter and then a one to one interview about their hydrogen engine developments.

Don't get me wrong, it's all good news for the climate etc.
But it does help when your son owns a hydrogen fuel company. www.ryzehydrogen.com

For someone with a big engine building business, using hydrogen for internal combustion makes sense. For the rest of us, less so.
There was no mention of the energy cost of making hydrogen, compressing it, transporting it, they did mention having to compress it further to put it into the fuel tanks, then expand it again without energy recovery before burning it.
If you are going to burn stuff in an engine, much better to use methane made in an AD plant from WASTE - manures, food waste and the like.
Hydrogen, being the smallest molecule, is very difficult to keep confined. Tanks are extremely high pressure, and very heavy and expensive for the amount of fuel they contain.
Hydrogen can have a role in energy storage, but it will be a fairly modest role.
Lord B talks about battery prices not coming down - they have dropped 10 fold in the last 12 or so years, and are still dropping. He does not understand what rare earth elements are, classing Lithium as one whereas Rare earth elements are a defined area of the periodic table, and lithium is a metal, and a relatively common one at that.

Absolutely brilliant, british engineering at its bestThe world seems to be obsessed with electric/battery vehicles and have such a blinkered view on it all . Well done lord Bamford and keep beating the drum for hydrogen
Think New Holland were the first to develop hydrogen powered tractors. Would be over 10 years ago now.
Not heard a great deal about them recently.

Let's hope it starts off the right sort of boom for renewables.

There’s already a massive government funded hydrogen test program going on on one of the Scottish islands. They’re using solar, wind and hydro electric to manufacture and store hydrogen through the day then the hydrogen is used at night for heating the homes and power generation.
Hydrogen will DEFINITELY play a massive part in the not to distant future as it’s a much easier way of storing and transporting carbon neutral energy.

hydrogen will work best when it is stored as water and split into H2 and O on the vehicle
until that process is in commercial development then its a non runner as renewable

I had a pony who could do that. Gelding, unfortunately, so not fully renewable.

I do think that hydrogen is important and great to see engines developed to run on it.
But currently, it's said online that 95% of hydrogen is made from fossil fuels and hydrogen from electrolysis method is 4x more expensive to make than from fossil fuels (before you factor in the power consumption).
So I think making of the hydrogen in a carbon neutral way at a reasonable price maybe a fair hurdle to get over.
It's alright having these fancy hydrogen buses in cities, but if the hydrogen comes from fossil fuels, then it's not great.

Where would you get the energy to split the water on a vehicle? If you have it on the vehicle, just use it to turn the wheels, don't mess about making hydrogen then burning it.
Test tube clone possible.

Nearly all the worlds engine manufactures have hydrogen fuel cell programs underway and several are already producing hydrogen cars on a commercial basis, Toyota and Hyundai. Interestingly British Rail have been running an experimental hydrogen fuel cell train for several years.

Although Hydrogen Cells as a power production look good, the negatives are listed in sjt01 post above. The devil is in the detail, and the production of hydrogen fuel is far from CO2 neutral, it also has very high energy consumption. We may as well use CNG as the stepping stone for trucks, tractors, plant, buses etc.

Wow, everyone invest heavily in hydrogen mining- it's the fuel of the future.
Why the fudge would you want a fuel cell to power a train- just power it with overhead electrical lines.
Lithium, despite being called a 'rare earth' material, is plenty common enough.
