Whilst PHES has an important role to play, I doubt its feasibility and affordability to address intermittency and fluctuation in seasonal demand for energy at high latitudes. For example, UK electricity generation from CCGT between 5 and 16 December 2022 was about 6 TWh. And the maximum monthly demand for natural gas in winter in the UK (eg 60 TWh in January) is nearly three times the summer minimum. UK total PHES capacity is currently less than 30 GWh. UK gas storage capacity is of the order of 10 TWh, considered by at least some people to be inadequate as a strategic reserve. And gas storage (which could be hydrogen or other synthetic low-carbon fuel in future) is much cheaper than PHES or batteries.
