Imagine a giant thermos that stores energy by turning carbon dioxide into a liquid and then back into a gas. Instead of using expensive chemicals or rare metals, it uses simple materials like steel and water. It acts like a massive rechargeable battery for the city, keeping wind and solar power ready for when the sun isn't shining.
Renewable energy is intermittent, causing electricity price crashes and grid instability. Current storage solutions are too expensive, degrade quickly, or rely on rare materials, making long-duration storage (8+ hours) economically unviable.
A closed thermodynamic loop energy storage system using liquefied CO2 as the working fluid. It consists of modular plants built from steel, water, and CO2.
If you are a grid operator dealing with unstable electricity prices and intermittent renewables — this project developed a CO2-based storage system that offers a levelized cost of storage of 68 €/MWh for 10-hour storage.
If you are a developer dealing with energy waste during peak production hours — this project developed a modular storage solution with a round-trip efficiency greater than 75% to save power for later sale.
If you are a factory owner dealing with high energy costs and a need for backup power — this project developed a system with a lifespan of over 30 years and a CAPEX of 183 €/kWh for the first-of-a-kind plant.
The CAPEX for the first-of-a-kind plant is 183 €/kWh, which is significantly lower than the 300 €/kWh typically seen for Li-ion batteries.
Yes, the system is modular, and installing modules in parallel allows the plant to reach the desired capacity for any specific application.
Based on available project data, the technology is developed by Energy Dome SPA, but specific licensing terms are not detailed in the report.
The use of off-the-shelf mature technologies and a simple process leads to a plant lifespan of more than 30 years.
No, the plants are constructed using only steel, CO2, and water, ensuring CAPEX stability by avoiding rare or critical materials.
The project is led by a single Italian SME, Energy Dome SPA, which holds 100% of the industry ratio. This lean structure suggests a fast-track commercialization path where the coordinator maintains full control over the IP and deployment strategy without the complexity of a multi-partner academic consortium.
