That’s simply not true, or at least not today.

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.

The ratio between GW and GWh is always an optimization of the fixed costs vs potential profit.

A 4 hour battery can run at 50% for 8 hours or 25% for 16 hours.

The determining factor is what the market needs.
