The UKs largest council-owned battery storage site, the 30MW Fideoak Mill site, is now fully operational. Located at South Somerset District Council’s (SSDC) site in Taunton, an additional £2.5 million of investment has allowed the council to commission a further 5MW, making it the largest site of its kind in the UK. It uses Kiwi Power’s proprietary hardware Fruit, which has been installed on all 22 battery units at the site. These will allow the batteries to provide balancing services to National Grid and participate in any of the UK’s 15 flexibility markets. Thomas Jennings, head of optimisation at Kiwi Power, said that councils were looking to make the most of sustainability investments in an effort to meet “increasingly stringent targets.”

The humble house brick has been turned into a battery that can store electricity, raising the possibility that buildings could one day become literal powerhouses. The new technology exploits the porous nature of fired red bricks by filling the pores with tiny nanofibres of a conducting plastic that can store charge. The first bricks store enough electricity to power small lights. But if their capacity can be increased, they may become a low-cost alternative to the lithium-ion batteries currently used. Strictly speaking, the power bricks are supercapacitors rather than batteries. Supercapacitors store electricity as a static charge in solids, rather through chemical reactions as in batteries. The advantage of supercapacitors is that they charge and discharge far faster than batteries, but to date they can only hold a small fraction of the energy. Researchers around the world are working to increase the energy density of supercapacitors, as well as the charging speed of batteries. Finding better ways to store electricity is a crucial part of fighting the climate crisis, as it would allow abundant but intermittent renewable energy to be stored until it is needed.
