The Columbia Energy Storage Project would store excess energy from the electric grid by converting carbon dioxide gas into a compressed liquid form and then converting that liquid back into a gas, powering a turbine to generate electricity, according to the Department of Energy.
Alliant Energy’s revolutionary Columbia Energy Storage Project, using Energy Dome’s safe, reliable CO2 battery, represents a significant advancement in energy storage while bolstering the power grid to benefit Wisconsin customers.
The gas will be stored in what officials call an “energy dome.” An Italian company named Energy Dome has already worked on the technology in a smaller-scale demonstration site in Sardinia, Italy. The Columbia Energy Storage Project would store excess energy from the electric grid by converting carbon dioxide gas into a compressed liquid form.

Alliant Energy filed an application with the state Public Service Commission on Aug. 7 to build a long-duration energy storage system in Columbia County.
Columbia County is currently home to a coal-fired power plant owned and operated by Alliant Energy, with partial co-ownership from WEC Energy Group — parent company of Wisconsin Public Service and We Energies — and Madison Gas and Electric. That plant is slated to come offline by mid-2026.
Then, when the stored energy is needed, the system converts the liquid CO2 back to a gas, which powers a turbine to create electricity. The energy storage system will be built south of Portage, Wisconsin in the town of Pacific and near Alliant Energy’s existing Columbia Energy Center.
The global industrial and commercial energy storage market is experiencing explosive growth, with demand increasing by over 250% in the past two years. Containerized energy storage solutions now account for approximately 45% of all new commercial and industrial storage deployments worldwide. North America leads with 42% market share, driven by corporate sustainability initiatives and tax incentives that reduce total project costs by 18-28%. Europe follows closely with 35% market share, where standardized industrial storage designs have cut installation timelines by 65% compared to traditional built-in-place systems. Asia-Pacific represents the fastest-growing region at 50% CAGR, with manufacturing scale reducing system prices by 20% annually. Emerging markets in Africa and Latin America are adopting industrial storage solutions for peak shaving and backup power, with typical payback periods of 2-4 years. Major commercial projects now deploy clusters of 15+ systems creating storage networks with 80+MWh capacity at costs below $270/kWh for large-scale industrial applications.
Technological advancements are dramatically improving industrial energy storage performance while reducing costs. Next-generation battery management systems maintain optimal operating conditions with 45% less energy consumption, extending battery lifespan to 20+ years. Standardized plug-and-play designs have reduced installation costs from $85/kWh to $40/kWh since 2023. Smart integration features now allow multiple industrial systems to operate as coordinated energy networks, increasing cost savings by 30% through peak shaving and demand charge management. Safety innovations including multi-stage fire suppression and thermal runaway prevention systems have reduced insurance premiums by 35% for industrial storage projects. New modular designs enable capacity expansion through simple system additions at just $200/kWh for incremental capacity. These innovations have improved ROI significantly, with commercial and industrial projects typically achieving payback in 3-5 years depending on local electricity rates and incentive programs. Recent pricing trends show standard industrial systems (1-2MWh) starting at $330,000 and large-scale systems (3-6MWh) from $600,000, with volume discounts available for enterprise orders.
