Executive Summary

Google is backing CO2 batteries and gas plants with carbon storage to secure cleaner, reliable power for data centers as demand rises

  • Google is investing in Energy Dome CO2 batteries for long-duration backup power at data centers
  • The Sardinia pilot stores 2,000 tons of CO2 and can generate 200 MWh of electricity
  • CO2 batteries are presented as a longer-lasting lower-cost alternative to lithium-ion storage
  • Alliant Energy is also moving ahead with a CO2 battery project in Wisconsin for 18,000 homes
  • Google and Broadwing Energy plan a 400 MW gas plant in Illinois with about 90 percent CCS
  • The Illinois project will store captured CO2 in ADM's EPA-approved Class VI site in the Mount Simon formation
  • Google says the CCS project is intended to help support reliable power for its expanding data centers
