A Landmark 5.8 GWh Thermal Energy Storage Project
In a major development for the long-duration energy storage (LDES) sector, Antora and Pratt Energy have officially announced a massive 5.8 GWh multi-day thermal energy storage project. Located at Pratt Energy's biorefinery in Pratt, Kansas, this facility represents one of the largest thermal storage deployments to date, highlighting the growing viability of non-electrochemical storage solutions.
Storing Electricity as Heat in Solid Carbon
Antora’s innovative thermal battery technology operates by storing excess renewable electricity as heat within solid carbon blocks. When energy is required, the stored heat is converted back into electricity and thermal energy. This unique approach allows the system to deliver power 24/7, effectively bridging the gap during periods of low renewable generation and providing true multi-day storage capabilities.
Antora’s thermal batteries store electricity as heat in solid carbon blocks, delivering it 24/7 under a long-term heat offtake agreement.
The project is backed by a long-term heat offtake agreement, ensuring stable revenue streams and demonstrating the commercial readiness of thermal LDES technologies in industrial applications. By integrating seamlessly with the biorefinery's operations, the system will optimize energy use and reduce the facility's carbon footprint.
Financing and Community Impact
The substantial project is supported by robust third-party equity financing led by Copenhagen Infrastructure Partners (CIP), with additional participation from Grok Ventures and the University Pension Plan Ontario (UPP). This strong financial backing underscores investor confidence in thermal storage as a critical component of the future energy mix.
Beyond its technological and environmental benefits, the Kansas project is expected to generate significant local economic activity. The construction and operation phases will create over 100 jobs and include various community initiatives, reinforcing the role of LDES projects in driving regional economic development while advancing the clean energy transition.
