MAN Energy Solutions and Energy Dome Collaborate on CO2 Battery Technology
MAN Energy Solutions and Energy Dome, an LDES solution provider based in Milan (Italy), have entered into a Memorandum of Understanding (MoU) for a non-exclusive collaboration. Both companies are committed to exploring the potential of integrating their individual technologies and competencies to further optimize Energy Dome’s CO2 Battery technology, a pioneering long-duration energy storage system addressing the increased need for energy storage solutions worldwide.
Matteo Falco, Head of Industries, Region Europe at MAN Energy Solutions, said: “Long-duration energy storage systems are vital to the success of the energy transition as they are the perfect complement to clean yet volatile renewable energies. Unfortunately, energy storage is lagging behind alternative energy production and preventing its widespread implementation. Various technologies with different capacities and characteristics must be utilized to bridge this gap. This is why we are very excited to embark on this new collaboration with Energy Dome. Together, we will leverage our collective strengths and expertise to accelerate the deployment of sustainable energy storage plants.”
Claudio Spadacini, CEO of Energy Dome, said: “In order to shift to fully renewable and sustainable energy, we need efficient and cost-effective ways to store it. Our CO2 Battery is a concrete solution that will change how sustainable, long-duration energy storage is adopted, making it more accessible and impactful for communities worldwide. The combination of MAN Energy Solutions' advanced turbomachinery know-how with our cutting-edge battery design ensures that anyone considering the adoption of our technology solution can do so with confidence.”
Energy Dome’s technology is based on a closed thermodynamic transformation of CO2 between its gaseous and liquid states. When operating in charge mode, the CO2 is withdrawn from an atmospheric gasholder, the Dome, and compressed into an inter-refrigerated compressor, driven by a motor. The heat generated from the compression is stored in a thermal energy storage system, whereas the CO2 is liquefied and stored in vessels under pressure at ambient temperature with zero atmospheric emissions. This allows for high-density energy storage without using extreme cryogenic temperatures. In discharge mode – whenever energy is needed – the CO2 is heated up, evaporated and sent into an expander before it flows back into the Dome. The expander drives the generator in order to feed climate-neutral electricity into the grid.
