German energy storage giant Sonnen has unveiled a new home and small commercial battery storage range, Sonnerbatterie 10, which includes a “performance” model that can store up to 55kWh, and a three-phase “island” solution that can power a house through a blackout. The new batteries, unveiled in Germany on Wednesday, have been developed as a “modular storage concept” with a storage capacity ranging from 5.5kWh to 27.5kWh for the sonnenBatterie 10 and 11kWh to 55kWh for the sonnenBatterie 10 performance. The “island solution,” which is officially called the Sonnen Protect 8000, is offered in the new range as an optional extra that provides three-phase full home backup in the event of a power failure.

“We are entering into a nearly exponential growth phase”, says Prof Paul Shearing. He’s an expert on emerging battery technologies at University College London. He expects electric vehicles alone to drive European battery demand up by a factor of 10 this decade. But this explosion in demand will only be possible if we can make batteries cheaper, more durable and more efficient. That is a big ask for any technology but fear not, Mr Musk’s proposed “battery day” comes thanks to a whole cascade of breakthroughs.

Construction is beginning on the world’s largest liquid air battery, which will store renewable electricity and reduce carbon emissions from fossil-fuel power plants. The project near Manchester, UK, will use spare green energy to compress air into a liquid and store it. When demand is higher, the liquid air is released back into a gas, powering a turbine that puts the green energy back into the grid. A big expansion of wind and solar energy is vital to tackle the climate emergency but they are not always available. Storage is therefore key and the new project will be the largest in the world outside of pumped hydro schemes, which require a mountain reservoir to store water. The new liquid air battery, being developed by Highview Power, is due to be operational in 2022 and will be able to power up to 200,000 homes for five hours, and store power for many weeks. Chemical batteries are also needed for the transition to a zero-carbon world and are plummeting in price, but can only store relatively small amounts of electricity for short periods.
