About the Company

Founded by a seasoned entrepreneur and a team of highly skilled engineers in process engineering and turbomachine and in intellectual property, EnergyDome has ideated and patented a revolutionary technology for large-scale and long-duration energy storage: The CO2 Battery.

About the Solution

The CO2 Battery is a proprietary technology based on a thermodynamic process that uses CO2 to store electricity cost-effectively with unprecedented round-trip efficiencies. With EnergyDome’s technology, it is possible to store large quantities of energy for long periods of time anywhere, without any site dependency, and deliver all the typical services of utility-scale storage systems, including grid regulation services. EnergyDome’s technology is particularly designed to just use readily available, off-the-shelf equipment—allowing for very fast commercialization of this solution.
