Google Signs Long Duration Energy Storage Partnership

Google has signed its first partnership with a long-duration energy storage (LDES) company, Energy Dome to support multiple commercial deployments worldwide to help scale the company’s CO2 battery technology.

The company has developed a 20MW/200MWh battery, which it claims has a lifetime of more than 30 years. According to Energy Dome, the technology does not rely on any critical minerals, only using water, steel, and CO2. It has a deployment time of under two years, with every component used in the system standard, which improves economies of scale.

“The programmatic and strategic deployment of our technology at scale to help Google reach carbon-free energy represents the core of our industry-first agreement. We’re proving that a 24/7 cost-effective and carbon-free energy supply is achievable with the right technology and partnership model,” said Claudio Spadacini, founder and CEO of Energy Dome.

In addition to the commercial partnership, Google has also made a direct investment in the company. The partnership is part of a broader push by Google to invest in LDES technology. It plans to support a growing range of LDES technologies currently under development through both commercial agreements to support more mature technologies, such as Energy Dome’s, in addition to earlier-stage investments.
