Hydrogen from unused electrical power generation

[patman post]

Interesting:

Tesla recently became the first party to trade flexible power in the UK's Balancing Mechanism (BM), which uses the National Grid's new control room API. This marked the first time that Tesla, which was able to acquire an energy generation license in June, was able to help balance supply and demand in Britain's electricity market.

The government today [14/7/2020] announced it will relax planning legislation to make it easier to construct large batteries to store renewable energy from solar and wind farms across the UK.
There is currently 4 GW of storage projects in planning which could power a combined 6 million homes, in addition to the 1 GW of battery storage already in operation.

Another mechanical (rather than chemical development) is the use of liquid air — a sort of update to Dinorwig. In the system, electricity is used during periods of low demand to compress and liquify air, which is stored ready to be fed back through turbines to generate electricity when demand is greatest...

This 50 megawatt-hour facility has been in operation in UK for over 2 years.

Batteries are still an infant application of storage technology:

Carnegie Road is Ørsted's first standalone, large-scale battery energy storage project at 20MW, although the renewable energy company also has a 2MW battery located behind the meter at its Burbo Bank offshore wind farm. This project supports the 90MW wind farm's production scheduling as well as providing some grid services.

The project in Japan will be completed by the end of March 2022.

Dinorwig Power Station in a mountain has been operating since 1984. But it was a massive engineering project.
Water is pumped up to a reservoir during off-peak times and released through turbines during period of high demand — ie, pumping is generally done when electricity is cheaper and generation when it is more expensive.

Off-site battery manufacture and hydrogen production appear to be less disruptive and less expensive energy storage systems..

Currently there seem to be few feasible ways of storing electrical energy for later use over the grid.

There are and some are already in place in the UK, (Japan is also widening there use.)

Wind farms across England and Scotland were handed £9.3 million to switch off their turbines to balance supply and demand and stabilise the grid.
National Grid made constraint payments to more than 80 wind farms, compelling them to switch off so supply didn't outpace demand on the windy, sunny weekend. That includes £6.9 million handed to 66 Scottish wind projects and £1.9 million paid to 14 offshore wind plants in England.
The total constraint payments for the day was more than double the previous record—£4.8 million paid to windfarm operators on 8 October 2018, when it was too windy. Last year, 86 windfarms were paid £136 million in constraint payments.

Currently there seem to be few feasible ways of storing electrical energy for later use over the grid. Admittedly Tesla has shown vast batteries arrays, but they seem for the future. More immediately, could potential unwanted electricity be used to generate hydrogen that would be stored for use when required by cars, vans, trucks, trains, etc, rather than switching off...?

Abso fucking lutely


Honda in Swindon know how to store it. Dip some carbon rods in the sea around the base of those offshore towers and have them crack the bloody seawater into hydrogen and oxygen, pipe the two to a facility near some unpopulated shore and let BOC do the rest like they have for decades.


But no, these wankers prefer the European Union answer of bribe them not to turn.
