See the discussion earlier in the thread for the discussion surrounding tidal energy and storage. All storage is expensive, as mentioned above I sense there is a hope millions of individuals' batteries (car, home) will add up sufficiently to kick the state's investment further down the track.roubaixtuesday wrote: ↑9 Dec 2022, 8:41amBiospace wrote: ↑8 Dec 2022, 11:26pm
What do I think are large storage technologies? In which case the Wikipedia page encapsulates things fairly well. Or what do I think would work best as large scale storage for the UK? For both nuclear and renewables? We don't yet know how well organised our production side will be, but we do know there is a lot of wind generation already and there is going to be a lot more. Storage a technology which is in development, not yet tried on a large scale. There are a lot of unknowns.
My thoughts: liquid fuel takes up a relatively small volume, does not leak energy and inefficiencies of production necessitate use of surplus-only energy. Could work well for inter-seasonal storage. Batteries are going to be widely owned for personal transport, it will make sense to use them using the Smart Grid despite the environmental costs. Good for lopping off those demand spikes, good for involving the public in an energy discussion. Tidal barrages and lagoons are yet to be trialled on a large scale, tides are totally predicable and reliable for daily production, we have good access to a lot of coastline potential. Added storage comes at a low marginal cost, in large quantities.
There's a lot left out in the above, it's a huge subject with a long way to go. Use of geothermal energy, larger grids and less waste will likely all play a part in reducing storage demands.
What liquids do you think can be used for storage?
What is the basis for "Added storage comes at a low marginal cost, in large quantities." - AFAICT the whole problem with storage is that it's ruinously expensive in large quantities, or indeed not feasible at all.
Liquid fuels as a form of energy storage? Many would work, this whole subject is under consideration. From https://www.scmp.com/business/article/3 ... ning-giant, this comment "For DRI to be economically sustainable in Asia, the price of each tonne of carbon dioxide emitted would need to rise to US$100, and the price of green hydrogen fall to US$1 per kilogram" shows how the market is a primary driver of behaviour.
As I'm sure you know, carbon trading in itself is a hotbed of discussion for many.
