CO2 based Utility-Scale Long Duration Energy Storage

Project description

Long-duration energy storage for the renewable revolution

The rapid expansion of renewable energy sources has brought us closer to a sustainable future. However, the intermittent nature of renewables demands efficient energy storage solutions. Conventional methods fall short when it comes to storing energy for extended periods, hindering the seamless integration of clean power into the grid. In this context, the EIC-funded CO2 Battery project uses CO2 as a working fluid. With a remarkable 75 % round-trip efficiency and a cost-effective CAPEX of EUR 183 per kilowatt hour, this technology empowers utilities, power producers and renewable energy developers to store massive amounts of energy for over 30 years. Its modular, site-independent design and reliance on common materials like steel, water and CO2 make it a vital solution for the energy transition.

Objective

CO2 Battery is a Long Duration Energy Storage system based on a closed thermodynamic loop that uses CO2 as working fluid. Thanks to the properties of carbon dioxide, the system allows to store energy efficiently and cost effectively. CO2 Battery metrics are:
- Round-trip efficiency (RTE) = 75% without degradation over time
- CAPEX = 183 /kWh (First-of-its-kind) able to drop to 103 /kWh with a capacity of 50 plants per year
- Lifetime = 30+ years
- Modular and site independent
- No rare material hard to supply or dismantle: it uses only steel, water and CO2.
CO2 Battery makes the energy transition possible, since the technology can store massive amounts of intermittent renewable energies. Customers are Utilities & Independent Power Producers, Renewable Energy developers, Large C&Is and energy transport and distribution operators. All of them need efficient systems to store energy for periods longer than 4 hours.
