UK’s giant battery ‘farms’ spark fears of explosions even worse than the Beirut port blast

The report says these batteries are not covered by the Control of Major Accident Hazards regulations, meaning they’re now popping up all over the place, sometimes near people’s homes. Any problems however serious have to be faced by the local fire services. Lithium-ion storage battery fires are far from rare, as well as notoriously violent, fiercely hot and difficult to deal with.

The first thing you notice is the noise – a strange, low-octave hum growing louder as you approach across the fields, says the Mail on Sunday (via The GWPF).

It’s coming from a group of bland metal cabins sitting on land that was once used to grow wheat and barley.

Yet these new agricultural buildings are nothing to do with food production. Instead, they contain huge batteries storing electricity for the National Grid – a new form of crop for farmers scrambling to cash in on the ‘green’ energy revolution.

And, according to a troubling new report from leading physicists, these vast batteries amount to electrical bombs with the force of many hundreds of tons of TNT.

With the potential for huge explosions, fires and clouds of toxic gas, they could devastate towns and villages nearby, says Wade Allison, emeritus professor of physics at Oxford University and co-author of the report.

The batteries, designed as reservoirs of spare electricity for when the wind doesn’t blow or the sun fails to shine, are spreading around the British countryside. And this, says Prof Allison and his fellow scientists, could spell catastrophe.

It’s like a potential bomb,’ he says. ‘When batteries catch fire, you can’t just squirt water on them and put out the flames. It’s evident from our research that nothing has been done to tackle this problem.’

The issues arise when these batteries, made of lithium ions – which are also used in mobile phones on a much smaller scale – overheat.

If just one cell becomes faulty, it can lead to a domino effect called thermal runaway, which spreads to neighbouring cells, causing a battery fire.

The resulting blazes are difficult to control because they don’t require oxygen to keep burning and need tens of thousands of gallons of water to extinguish. Temperatures have been known to hit 660c – enough to melt aluminium.

Mail on Sunday said nearby residents, who were ordered to stay indoors, had their homes rocked by the explosion.

This is not nimbyism at all,’ Prof Allison adds. ‘This is a potential Grenfell Tower-like fire. People will be killed.’

A Mail on Sunday investigation has identified nearly 400 battery sites – from Newquay to the Scottish Highlands – which are either operational or in development.

And thanks to a relaxation in planning laws, 104 of these have been proposed in the past year alone – including in the village of Stocking Pelham in Hertfordshire’s Ash Valley.

When The Mail on Sunday visited, we were struck by the noise from the nearly four-acre plant.

The hum came mostly from the air-conditioning units keeping 150,000 battery cells cool in what look like white holiday cabins. ‘Keep out’ signs on the perimeter fence warned of 33,000 volts.

But the site wasn’t supposed to look like this at all, reveals Jo van Riemsdijk, a 48-year-old mother- of-two who lives nearby.

‘We were told that the first battery plant would be virtually hidden,’ she says.

‘The cabins were supposed to be a greeny-brown and the developers were supposed to plant trees to shield them.

‘What we have is a series of hideous white boxes that are very obvious. They make a hell of a noise.’

Yet there are plans for a second plant on a 3½-acre site close by and another proposal for a third to be housed on a nearby solar farm – just a field away from Mrs van Riemsdijk’s home.
