Researchers look at electricity grid resilience using advanced batteries


A new research partnership, from Loughborough University and the University of Warwick, will show how advanced lead batteries can support electricity grid energy storage and plug-in to more renewable and other storage requirements for low carbon energy systems.

The project is being supported by the Consortium for Battery Innovation (CBI).Demand for batteries as a storage technology is steadily growing across the globe in order to support greater levels of grid flexibility, reliability and decarbonisation as more renewables are integrated into the grid and in the face of extreme weather events.

By developing more advanced levels of modelling and prediction of lead battery behaviour for utility grid storage, the research is geared towards facilitating higher uptake of lead batteries to support the energy grid.

Professor Dani Strickland, of Loughborough’s School of Mechanical, Electrical and Manufacturing Engineering, said: “The availability of low-cost powerful microprocessors is fuelling an explosion in our capability to monitor, understand and impact battery degradation in real world situations at low cost.

“This project is exciting because it will use expertise in the partner organisations to transition lead acid batteries to the world of big data and smart energy storage.

“Loughborough are very excited to be part of this project and consortium. The battery cycling facilities at Warwick University are some of the best in the UK.

“Our ability to access the data from their testing will give us the opportunity to gather and analyse data in ways that would not have possible without this consortium.

“In particular, on improving our understanding of battery mitigation control strategies using advanced battery monitoring.”

Europe’s energy storage transition over the last few years has witnessed tremendous growth, increasing from 0.55 GWh 2016 to 5.26 GWh by the end of 2020, with front-of-the-meter deployments such as utilities leading the way, representing more than 50% of installed capacity.

These energy storage systems require high-performing, reliable and affordable batteries to ensure the smooth generation and storage of energy for regional and national electrical grids.

Professor Richard McMahon, from the University of Warwick, said: “We are really pleased to be working with the CBI on the use of lead batteries in energy storage applications.

“Lead batteries have key benefits of safety and recyclability but there is work to be done to understand how best to manage lead batteries in energy storage service to optimise efficiency and prolong life.

“This knowledge will show owners and operators of storage facilities that lead-based systems provide a safe and cost-effective solution.”

By combining innovative research techniques such as electrochemical impedance spectroscopy, researchers will study and predict the performance and lifetime of lead batteries in various utility duty cycles.

The model developed by researchers will be compared to data gathered from actual lead batteries in the field, significantly aiding the understanding of how the technology is used in utility grid applications and how these factors impact battery lifetime.
