Energy Dome is developing a long-duration system that stores energy by manipulating CO2 in various states. Sauer Energy says the company launched its first commercial long-duration CO2 storage plant in Sardinia on June 8, 2022. This the first known grid-connected storage application of this type, and this is therefore a significant moment.
How Commercial Long-Duration CO2 Storage Works
The Energy Dome system draws CO2 gas from atmospheric storage in charging mode. Then it compresses the gas in an inter-refrigerated container, while storing the thermal heat generated elsewhere. The storage system then curates the compressed gas in liquid form for future use.
When the interconnected customer electricity grid places an order, the Energy Dome evaporates the liquid CO2 back to gaseous state. The expanded stream flows through a preheated turbine generating electricity for the customer. Meanwhile the gas returns to atmospheric storage without any leakage loss.
Long duration storage hence lends itself to peak grid-load balancing, and emergency power during short duration outages. It uses an abundantly available resource freely available from nature, and should cause no pollution under correct use.

Sardinia is the second-largest island in the Mediterranean, and a province of Italy. The mother nation’s energy is vulnerable, because it is heavily dependent on imported oil and gas. However, the island itself encourages renewable energy through financial incentives.
The Energy Dome demonstration project impressed Sardinian authorities, because the system can deploy rapidly unlike other types of peaking stations. The company has secured its first order for a 20MW, 5-hour facility, and is preparing for projects in Italy, Germany, the Middle East and Africa.
This seems like a great component for the renewable energy mix the world needs urgently now. We particularly like it because it is a giant battery, functionally speaking. And batteries and renewable energy are our two great passions.
