Yeah, pumped hydro has response times on the order of 10s of seconds, but the capacity is only useful for short term generation. For example, the UK has 24 GWh

Yeah, pumped hydro has response times on the order of 10s of seconds, but the capacity is only useful for short term generation. For example, the UK has 24 GWh of installed PHES capacity. Last year the UK used ~915 GWh per day on average, so best case about ~40 minutes worth of consumption.
PHES is for peaking and grid stability, not long term storage.
- CBarkleyU 4y agoWhat is long term storage in the context of renewables? Scaling UKs PHES capacity times 40 so that it lasts a whole day doesnt seem like an impossible task. I might be naive, but it seems extremely possible, given how those 24 GWh capacity were achieved with little to no political support.
