In this episode, Katharine Blacklaws speaks to experts from Leeds City Council, the University of Leeds and Star Refrigeration about the GeoGrid innovation project. Together, they explore how geothermal heat storage could transform heat networks by storing low-cost, low-carbon heat underground for months at a time. They discuss how seasonal heat storage could reduce electricity demand at peak times, lower operating costs, improve energy security and help scale heat networks as the UK electrifies heat.
