Hydrogen Vs BEV cars.

A new study shows Earth may hold an untapped energy source — trillions of tons of hydrogen gas buried deep beneath the surface.
Best of all? It could power the world for centuries on end.
According to research led by Geoffrey Ellis of the U.S. Geological Survey, these hidden reserves could provide enough energy to reduce global reliance on fossil fuels for 1,000 years.
Formed naturally through geochemical processes, this geologic hydrogen is estimated to total around 6.2 trillion tons (5.6 trillion metric tons), with significant potential to serve as a low-carbon energy resource.
While hydrogen reserves have already been identified in places like Albania and Mali, researchers believe similar deposits exist worldwide. However, much of this hydrogen is likely buried too deep or located offshore, making large-scale extraction a challenge. Even so, the study, published in Science Advances, suggests that tapping into just 2% of the estimated reserves could meet the world’s hydrogen needs for 200 years, helping achieve net-zero carbon goals.
The energy contained in these reserves exceeds that of all proven natural gas deposits, highlighting the potential of hydrogen as a clean alternative. However, experts like Prof. Bill McGuire of University College London warn that developing the infrastructure to extract hydrogen at scale would require a massive global effort. Despite these challenges, the study underscores the need for further research into geologic hydrogen, which could play a critical role in the transition to sustainable energy

See my post above. I’d highly commend the Naked Scientists podcast on this and other fronts as well.

Trouble is that the places where people want to put solar farms in the UK are in the south and east as that's where it's most sunny, but that's also where the best farmland is and Grade 1 land growing wheat can produce something like 50x the calories/acre of a typical sheep farm. Now Grade 1 land can produce more sheep than the average hill farm, but there's still no comparison to what it can produce under cereals. People don't appreciate just how much better prime farmland is compared to the average, and it seems ... suboptimal to take it out of cereal production in favour of PV, which is the usual choice in this country.

You’re right on the money here. I haven’t seen the calorie comparison before. Once the infrastructure for a solar farm is in place, scaling must be easy. If we had joined up thinking from different government departments the solution is obvious, developing 10% bigger solar farms further north will not be 10% more expensive and the good land can grow good quality grains. It’s not rocket science, but one department is energy and the other is agriculture so its a crap shoot as to what decisions will ever be made.

It will happen one day, and hydrogen will be king

Absolutely, but in 5 to 10 years time. In the meantime the climate is going downhill fast. We need to ditch fossil fuels wherever possible NOW. We can’t sit on our hands and wait for large scale technology to catch up. I still want to be able to take ski holidays in Europe, but last years experience of watching a piste melt away in the middle of February at over 1000m altitude was heart breaking.

So skying is more important or the loss of money
