Google invests in carbon dioxide battery for renewable energy storage
Google has partnered with Italian startup Energy Dome and invested in its long-duration energy storage (LDES) technology. The deal involves using Energy Dome's carbon dioxide battery to store excess renewable energy and dispatch it when needed. Unlike lithium-ion batteries, which can only store energy for up to four hours, Energy Dome's CO2 battery can store and continuously dispatch energy for 8 to 24 hours. This allows Google to rely more on renewable power even when there is no wind or sun. The technology uses compressed carbon dioxide gas to store energy and then expand it back into a hot gas to generate electricity. Google believes that this partnership and investment can help it achieve its goal of operating on renewable energy 24/7 by 2030, as Energy Dome's technology has the potential to "commercialize much faster" than some of Google's other clean tech investments.
