Energy storage plays a key role in DoD mission readiness because it allows excess energy that is generated from renewable sources to be stored either for future use during events such as grid outages, or to generate savings and revenue by participating in utility ancillary service programs. It also enables seamless transitions between alternative generation sources to provide continuous supplies of power and energy.
Of the different categories of energy storage, including mechanical, electrical, thermal, and electrochemical (battery), Battery Energy Storage Systems (BESS) have made significant advancements in capacity, cost, and market penetration in electric-utility applications. ESTCP is evaluating BESS technologies and applications to improve DoD installation energy security, reliability, and resilience.
In addition to electrical system applications, ESTCP is also demonstrating thermal energy storage technologies with HVAC applications. Thermal-energy storage projects can be found under the HVAC topic.
