Use surplus electricity from wind turbines to isolate and liquify hydrogen?

That is the 'super power' quoted in the report.

There is no doubt in my mind that this is possible, but to then send the hydrogen down a pipe and use it to create heat to heat people's homes??? You might as well just connect the wind turbines to air source heat pumps for heating and then to A/C units when they need cooling.
Agree however hydrogen will have applications say in the likes of heavy trucks and tractors where you need an intense power source and long range.

The proposed use of hydrogen in this way represents a herculean pain in the chuff as hydrogen itself is a pants way to store or transport energy.
Heavy vehicles also ready run on hydrogen- only it is hydrogen attached to much larger molecules containing carbon- hydrocarbons. These molecules contain dozens of carbon-hydrogen bonds and are very convenient because they are all basically liquids at typical temperatures. If you want to run a process like combustion on pure hydrogen you are relying on the measly wussy chemical bond between two hydrogen atoms.
It would be far far better to use a molecule other than one comprised only of hydrogen as a fuel source. Wind power can be used as can be any source of high end process heat. Some substitutes may be: DME, ammonia, methanol or similar, all made from water and the air making them totally carbon free.

I've raised the methanol route before but met no enthusiasm.

There's some sort of pinch point ahead in Ye Greate Decarbonising Planne because air source heat pumps, although good, require upgrades to larger radiators in addition to costs and upheavals of installing the pumps themselves. If domestic systems already have natural gas boilers, then it's thought a swap can be made for hydrogen without those additional costs.

Its amazing how strong concrete can make a structure if you place plenty of it on any type of ground.

They sure put plenty concrete in the bases here in the peat.!

300ton i beleve holding big turbines up no far from me on boggy moorland!

Isn’t concrete meant to be carbon unfriendly stuff

id imagine so yeah. but those thats collecting the big payout for them being there aint worried about that & after all generating power this way is pretty much the way to go isnt it?
id put a 100 of the buggers up right across the vast moorland where only a tiny part is used for all of these ones

Good, so those of us with oil fired heating systems can just switch to a biodegradable alternative and carry on as normal?

ive got a hefty piece of land here thats pretty much a peat bog, thankfully its in HLS & i hope this can be continued into something similar inside ELMS as there is bugger
all else you can do with it. rough grazing for a few months of the year & thats pretty much it
EDITED
but the birds n other wildlife thrive in it for the rest of the year. big ticks public good keeping at as a wildlife intended...

As long as it doesn't contain palm oil, or soya oil. It can contain rendered oils from abattoir waste, though. (That's a personal choice.)
And, as long as it a) doesn't choke the burners (some makes are more delicate than aircraft standard, from what the engineer said), and b) stays stable in wet and cold weather.

Think about the carbon used in building a 2,000Mw coal fired power station.
Then think about the ton of coal fed into the furnaces every 10 seconds.

Taken from the Solar Power Portal;
During 2020, I have been writing extensively about the sheer volume of new large-scale solar planning activity, across both new pre-application screened/scoped sites and with full planning applications, heavily weighted to 49.9MWp-dc occurrences.
In fact, during November alone, 1.2GW of new UK solar farm capacity was added to the pipeline, a record amount in any single month. At the end of November, the UK pipeline had grown to 13.4GW. Incredibly, more than half of the 13.4GW capacity was added during the first 11 months of 2020. 2019 – the first real year of planning rebound – saw about 2.9GW of new sites captured.
Here is the latest graphic charting the growth of the UK utility-scale pipeline, right up to the end of November 2020, taken from the December 2020 release of the UK Large-Scale Solar Farms: The Post-Subsidy Prospect List report available on subscription through the link here.
Since April 2020, new site identification of large-scale solar farms in the UK has been operating at a blistering pace, with the past few months seeing 800-1200 MW per month added to the pipeline.
During 2019 and 2020, more than 10GW of new site capacity has been identified by planners in the UK – a massive amount by any standard. Of the current 13.4GW pipeline capacity, about 8.4GW (245 sites) is at pre-application stages (screening/scoping). The rest is in the planning system, with about 3.23GW having been approved (subject to conditions being discharged).
