First of, the UK are investing in battery storage, there’s already a rollout of grid-level battery systems across the country*.
None of them hold capacity for longer than 2 hours before they need to start discharging. In fact, the record breaking duration is 6 hours. This is great as a short buffer, but it’s not “storage”.
To put this in perspective, last year the UK went 2 weeks without any significant wind, so a 2 hour buffer is nothing. This is why Hydrogen is still being kept as an option for long term storage.
