University of Oxford wins funding to investigate grid energy storage, with potential for significant carbon emissions savings
“This project will enable greater grid carbon emissions savings by demonstrating how energy storage may best be sited and controlled from an environmental perspective”.
To move away from fossil-fuelled generation to clean sources of energy such as wind and solar, substantial amounts of energy storage could be required to meet net-zero targets. Energy storage systems such as batteries are key to providing grid stability and ensuring that energy is available when it is needed.
However, it is not clear whether the financial and environmental benefits of grid storage currently align. For example, if storage is placed far from excess renewable generation, on the other side of a congested network, then it may be charged from fossil-fuelled power stations.
