The Inflation Reduction Act of 2023 is a game changer! It extended the 30% investment tax credits for solar, wind, geothermal, and electric vehicles, with new requirements. More importantly, it expanded the technologies that qualified for 30% ITC to energy storage systems, and specifically, thermal energy storage systems. It also has a bonus ITC of 10% if the systems met US content requirements. Most ice storage systems, or thermal batteries, will receive a 40% ITC, which makes a chiller plant with storage less costly than a chiller without storage. The goal is to be 100% renewable energy on the grid by 2050. That cannot be achieved without energy storage. Electric batteries are very expensive, degrade over time, and use scarce materials. Thermal storage systems use water. They have been utilized for over 30 years and are proven, reliable, and cost-effective, especially now with a 40% tax credit. Thermal batteries can only reduce peak electric demand by 40% by turning off the chillers and electric batteries will need to operate the lights, pumps, fans, and plug loads. NREL is encouraging hybrid batteries for buildings—thermal batteries and electric batteries.
