A recent study from the University of Nottingham in England highlights the extensive storage capacity demands the UK will face for decarbonizing domestic space heating. Lead researcher Bruno Cardenas emphasized the significant challenge of deploying enough storage to meet future heat pump-driven demand. The research projects a 26% increase in annual electricity demand and a 70% rise in peak load when heat demand is fully electrified. To address this, the study suggests a need for substantial investment in long-duration energy storage solutions like hydrogen caverns and compressed-air energy storage (CAES). The model presented envisions a scenario with 175 TWh of combined storage capacity, emphasizing the importance of preparing for future energy demands and addressing peak usage periods. Cardenas also underlines the necessity to take immediate action to ensure the availability of sufficient long-term storage solutions due to the lengthy timeline associated with developing new technologies. While batteries were not considered in this study, their role in providing short-term flexibility was acknowledged. The analysis stresses the need for proactive measures to manage future demand spikes and highlights the importance of energy storage in supporting the transition to a decarbonized heating system in the UK.
