Problem
The increasing reliance on intermittent renewable energy sources like solar and wind necessitates scalable and cost-effective long-duration energy storage solutions. Existing battery technologies face limitations in terms of cost, scalability, and environmental impact, hindering the widespread adoption of renewable energy and grid decarbonization.
Solution
Energy Dome offers a long-duration energy storage system based on a thermodynamic cycle that uses liquid CO2 as the working fluid. The system charges by compressing CO2 and storing it in a liquid state within a "Dome" gasholder. When energy is needed, the liquid CO2 is evaporated and expanded through a turbine, generating electricity and returning the CO2 to the gasholder. This closed-loop process utilizes off-the-shelf components and sustainable materials, providing a scalable, reliable, and cost-effective solution for storing renewable energy. The technology enables efficient energy retention and dispatch, facilitating grid decarbonization and enhancing energy reliability.
Target Audience
The primary target audience includes utility companies, independent power producers (IPPs), and grid operators seeking long-duration energy storage solutions to integrate renewable energy sources and enhance grid stability.
