Trump announces trade deal with EU following months of negotiations
Investing.com -- Google (NASDAQ:GOOGL) announced a new partnership with Energy Dome on Friday to deploy long-duration energy storage (LDES) technology globally, marking the tech giant’s first step into this clean energy sector.
The collaboration includes both a commercial partnership and an investment in Energy Dome, though specific financial details were not disclosed. Google plans to support multiple commercial projects worldwide to deploy Energy Dome’s CO2 Battery technology, which can store excess clean energy and dispatch it back to the grid for 8-24 hours.
Energy Dome’s technology works by using carbon dioxide gas in a dome-shaped battery. When renewable energy is abundant, the system compresses CO2 into a liquid. When power is needed, the liquid expands back into a hot gas under pressure, spinning a turbine to generate carbon-free electricity.
The Italian company has already demonstrated its technology’s viability by operating a commercial demo facility that has been injecting electricity into the Italian grid for over three years. Energy Dome has also secured contracts for commercial-scale projects in Italy, the US, and India, and currently operates a full-scale 20MW-200Wh commercial plant.
Google stated that these projects could unlock new clean energy for grids where the company operates before 2030, supporting its 24/7 carbon-free energy goal. The tech giant emphasized that LDES technologies can cost-effectively integrate growing volumes of renewables onto power systems and contribute to more flexible, reliable grids.
According to the LDES Council, deploying up to 8 terawatts of LDES by 2040 could result in $540 billion in annual savings globally, partly due to their ability to optimize grid operations.
Google indicated it plans to support additional LDES technologies through both commercial agreements and earlier-stage investments as part of its broader clean energy portfolio, which includes enhanced geothermal, advanced nuclear, and fusion technologies.
