The best back-up power for the long term will be green hydrogen, and action is needed now to commercialise this technology as fast as possible.
Hmm - I'm yet to be convinced that this should the current focus... though this is the one application in which I do see a future for hydrogen as long/medium term storage. I'm not saying it shouldn't have effort put into it, but it does seem to be the focus of too many headlines.
I'd be happier to see much faster movement on the low hanging fruit (like planning laws, regionalised pricing etc), with a focus on cutting the amount of time we need to burn anything at all.
Yes, we'd like to get to the point where we can generate and store hydrogen effectively over a period of months, but that's not going to happen faster than we can get the rest of the systems in place. About the only thing slower will be retrofitting 20+million homes with better insulation and more efficient heating systems.
We do really need to stop the price gouging by the gas plant operators, and get NESO to treat demand management as an equally valid method of balancing the grid.
On the 8th of January there were two ways that the grid was balanced:
- DFS was called upon, incentivising consumers to reduce usage, or increase export. NESO paid 90p/kWh (of which I saw 72p)
- Gas peaker plants were called upon, and were paid £5.75/kWh

That's an insane difference for the same power from different places. The result of the low offer to consumers is that only a quarter of those who took part last year bothered.
Yes, DFS is probably worth a little less to NESO, because it's not "guaranteed" power, but whilst an individual consumer might vary behaviour from one week to the next the aggregate behaviour is consistent.
