Heat Battery for Electrical Grid Energy

Summary

This document, from Lawrence Livermore National Laboratory, outlines a concept for a heat battery system designed to provide cost-effective energy storage for renewable electricity generation in the United States. The challenge is to overcome the non-dispatchable nature of renewables and the high cost of current battery solutions, with global electricity consumption expected to more than double by 2050. The proposed heat battery system aims for national deployment by 2040 with a total cost not exceeding US$100 billion, while ensuring consumer utility bills do not increase by more than 5%. Key performance targets include greater than 95% recharging efficiency, greater than 70% discharging efficiency, and the ability to regulate grid voltage and frequency within 10-60 seconds. Each battery factory is targeted to cost US$4 million or less to install.
