Energy Dome, a long duration energy storage company, on July 25 announced a global commercial partnership with Google using Energy Dome’s CO2 battery technology “to enable carbon-free energy for the grids that powerGoogle’s operations.”
Alongside the commercial agreement, Google has made a strategic investment in Energy Dome.
Google’s first commercial long-duration energy storage deal “is part of a growing portfolio of advanced energy technologies needed to realize its ambition to run its operations on 24/7 carbon-free energy by 2030,” Energy Dome said.
“The selection of Energy Dome’s proven and market-ready CO2 battery technology reflects its ability to be deployed at the scale, speed and affordability required on a global basis,” Energy Dome said.
Energy Dome’s CO2 battery is capable of continuously dispatching energy for periods of 8 to 24 hours, unlocking enough firm electricity to meet both the baseload and flexibility requirements of large energy users, it noted.
“The modular, site-independent product design uses off-the-shelf equipment without supply chain bottlenecks, ensuring a highly scalable solution to store massive amounts of energy efficiently and cost-effectively,” the company said.
Furthermore, the mechanical components of the technology help stabilize the grid by providing natural inertia from rotating machinery.
“This is especially important given the concurrent ramp-up of solar and wind (which lack inertia) with the ramp-down of legacy fossil-fuel power stations, whose inertia is lost when the plants are decommissioned. The CO2 battery thus contributes to maintaining grid resiliency by acting as a shock absorber to smooth out sudden changes in frequency.”
The commercial agreement aims to develop CO2 battery projects in all the key geographical strategic areas, including Europe, the U.S., and the Asia-Pacific region, with the goal of scaling up deployment at a rapid pace to meet Google’s 2030 carbon-free energy goals.
A pipeline of sites and projects has been identified in the partnership, which are currently in development and contracting stages.
Beyond the commercial collaboration, Google has also made an investment in Energy Dome. The investment coincides with the company entering a growth phase of commercial deployment, and multiple projects already contracted, including with Alliant Energy in the U.S., Engie in Italy, and NTPC in India.
By investing directly in the Milan-based scaleup, Google is reinforcing its long-term commitment to accelerating the commercialization of this proven technology.
The Public Service Commission of Wisconsin recently approved plans to construct a first of its kind long-duration energy storage system of its kind in the United States that will use Energy Dome’s CO2 battery.
