‘Bombs’ are designed to store and quickly release copious amounts of energy, so are the mega-batteries said to save wind and solar from their hopeless intermittency.

The notion is that giant lithium-ion batteries will quell the power delivery chaos that comes with attempting to rely wholly weather-dependent wind power and wholly sunshine-dependent solar power; thereby bringing stability and security to plenty a power grid teetering on the brink of collapse, all the consequence of our “inevitable transition” away from reliable and dependable power generation sources, like coal and gas.

But there’s nothing ‘stable and secure’ about lithium batteries.

As Samsung mobile phone owners are painfully aware, lithium batteries have a horrifying habit of spontaneous ignition. STT has fond memories of watching fellow airline passengers being berated for having a Samsung 7 in their pocket.

And there have been plenty of incidents where the lithium batteries in Tesla’s electric cars have exploded in flames.

Now, it’s grid-scale explosions and conflagrations that we need to be concerned about, not just the odd exploding Telsa S and Samsung 7.

Here’s a little saga from the land Downunder, where a giant Tesla decided to release a whole of ‘wonderful green’ energy in a furious hurry.

A toxic blaze at the site of Australia’s largest Tesla battery project is set to burn throughout the night.

The fire broke out during testing of a Tesla megapack at the Victorian Big Battery site near Geelong.

A 13-tonne lithium battery was engulfed in flames, which then spread to an adjacent battery bank.

More than 150 people from Fire Rescue Victoria and the Country Fire Authority responded to the blaze, which has been contained and will be closely monitored until it burns itself out.

“If we try and cool them down it just prolongs the process,” the CFA’s Assistant Chief Fire Officer Ian Beswicke said.

“But we could be here anywhere from 8 to 24 hours while we wait for it to burn down.”

The Tesla battery is expected to become the largest battery (or bomb) in the southern hemisphere as part of a Victorian Government push to transition to renewable energy.

Ambulance Victoria members are also on site monitoring the health of firefighters.

A toxic smoke warning has been issued near Geelong.

Residents have been warned to close windows, close fireplace flues and bring their pets inside in the Batesford, Bell Post Hill, Lovely Banks and Moorabool areas.

No-one was injured and the site has been evacuated.

Australian Energy Market Operator (AEMO) said the battery had been isolated and disconnected from the main electricity grid and “there are no implications” for supply.

The Tesla battery was paid for by renewable energy company Neoen.

Neoen Australia’s Managing Director, Louis de Sambucy said Neoen and Tesla were working closely with emergency services on site to manage the situation.

Ian Beswicke: Yeah, the plan is that we’ll let the battery bank burn itself out. Now it’s about 15 metres long by three metres high by three metres wide. There’s another one right beside it that is currently burning as well. So we cannot put them out with water or anything else. The best way to deal with these things is to let them burn until they are burnt out. If we try and cool them down, it just prolongs the process. So by letting them burn, and this wind is helping us by keeping it burning fairly freely, but we could be here anywhere from eight to 24 hours whilst we wait for it to burn down.

So, there you have it – when one of these ‘planet saving miracles’ spontaneously bursts into a lethally toxic fireball, it’s a case of burn, baby burn!  No point attempting to extinguish the blaze, just keep clear of the toxic fumes and let it eventually burn itself out.

And here are a couple more for your “Blazing RE Battery” scrapbook – care of the team from Jo Nova.

Big batteries could be bigger bombs than Beirut Fertilizer

It turns out storing Megawatts of high density energy in a confined space is “like a bomb”. Who could have seen that coming, apart from everyone who understands what a megawatt is?

Clean, green, noisy and explosive.

And they are “unregulated” in the UK.

UK’s giant battery ‘farms’ spark fears of explosions that can reach temperatures of 660C

…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.’

Given the size of the proposed plants, Prof Allison says this could, in theory, lead to an explosion several times bigger than the one that destroyed the harbour in Beirut last year.

The threat of fire is not merely theoretical. South Korea saw 23 battery farm fires in just two years. A recent battery fire in Illinois burned for three days and thousands of residents were evacuated.

Such blazes release highly toxic gases. One – hydrogen fluoride – is lethal if inhaled, and causes irreversible health effects after an hour of exposure, according to Public Health England.

Meanwhile 3 – 4,000 people were evacuated in Morris Illinois the week before last, as 100 tons of batteries burned. The fire burned for days. They could not use water or foam, and in the end, the burning batteries were smothered with 28 tons of cement.

These were run of the mill cell-phone and car batteries.
