Energy Dome: Long-duration energy storage innovator 

Energy Dome is a company with revolutionary technology for large scale and long duration energy storage. 

Founded by Claudio Spadacini, Dario Rizzi and Francesco Oppici, Energy Dome is changing how we store energy and helping the environment by making solar and wind power available all day, every day. 

The company created a CO2 Battery, a long-duration energy storage system that makes energy storage viable globally today. 

It works based on a thermodynamic process that uses CO2 to store electricity cost-effectively with unprecedented round-trip efficiencies.

The company says that with this 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, maximising investment returns for customers.

Claudio Spadacini, founder and CEO of Energy Dome, says, “We offer our customers unparalleled flexibility and value. They can enter into long-term capacity offtake agreements with Energy Dome, where we will fund, build, own, and operate the CO2 Battery for the customer under a Storage-as-a-Service model.”

He adds, “This allows the customer to have reliable, clean and affordable power far below the cost of pumped hydro or Lithium Ion. Alternatively, the customer can opt to buy the CO2 Battery directly from Energy Dome with a performance guarantee under an Original Equipment Manufacturer model.”
