‘Four storage solutions to help Britain keep the lights on deep into the future’ says the paper’s sub-heading.

What about actual reliable power for heating, transport, industry, commerce, hospitals, shops, services etc.?

Soaring energy bills rooted in a global gas supply crunch have focused minds on the age-old problem: how can we better store power? says The Guardian.

Attention has turned to the closure of the Rough gas storage facility in the North Sea in 2017, which left the UK with only enough storage to meet the demand of four to five winter days.

But while gas is being phased out, Britain’s growing reliance on renewables, such as offshore wind and solar, does not solve the problem of intermittency – what happens when the wind does not blow or the sun does not shine.

The key to securing enough affordable, low-carbon energy is more storage to make the most of the renewable energy available. A storage boom has been forecast over the coming decade as governments race to meet their climate targets.

Their four suggestions:
— ‘Gravity’ storage
— Concentrated solar power storage
— Green hydrogen
— ‘Cryogenic’ batteries

If anyone finds any or all of these a convincing and/or ‘affordable’ alternative to existing fuels as a storage medium, please explain why.
