Power Storage Is The Next Big Net Zero Challenge

The title of this post, is the same as that of this Opinion from Bloomberg.

This is the sub-heading.

Britain’s pioneering plans for renewable energy show the global need could be massive. The means don’t yet exist.

The opinion is very much a well-written must-read.

One new project the article mentions is a 30 GWh pumped storage project at Coire Glas in the Scottish Highlands, that is planned by SSE.

I discuss this scheme in The Coire Glas Pumped Storage Scheme.


Bloomberg didn’t say it, but this pumped storage scheme could give the UK energy security.

  1. No brainer but watch the environmentalist movement rise up in anger over it despite its essential to get to net zero.

    Good though it is still only enough energy storage for about an hour of demand this time of the year.

  2. Well even as you were writing this post the ITT had just gone out, so it looks as though the next phase is underway.
    Along with Cruachan 2 this is a sorely needed development and we could really do with one more decent sized facility on top of these two. Batteries are not the answer and with the dependence on intermittent wind, if we’re going to need more a stable power source.

    • Coire Glas has all the planning permissions, so hopefully it will run smoothly.

      Cruachan 2 doesn’t add to the storage, but it does increase the power output, so it will be available for a shorter period of time.

      Does that mean, the two go well together?

      We need batteries everywhere. There will smaller lithium-ion ones to stabilise things at a local level and bigger ones up to about half a GWh sitting on sites about the size of four tennis courts close to major substations. New entrants Energy Dome, Gravitricity, Highview Power, RheEnergise and a few others will be able to handle the latter.

      • I suppose I should have made it clear that my comments about batteries was intended to rebut those who believe batteries are the universal panacea to shore up a power supply based by ever increasing amounts of wind and other intermittent forms of generation.
        If you had said, we need energy storage, as opposed to batteries, everywhere I would be in agreement with your concluding remarks.
        I still believe that there remains a role for tidal power generation. There may be questions around its environmental impact and of course the capital cost may be viewed as a negative but the fact that it is more predictable than the wind and shouldn’t be overlooked.

  3. I worked for Frederick Snow and partners and was shown all their plans for the Severn Estuary, which would have created 10% of the UK’s power. Their plan from the sixties would also have created an airport in the middle to replace Heathrow for flights to and from the West and a second road crossing.

    Dusted down and updatedfor the 21st Century, it could be really something.

    • Won’t wash with the environmentalists and therein lies the irony that even green goals are going to be nigh on impossible to achieve.

      Personally I’d just dust down the AGR plans they’ve served us extremely well.
