As we endeavor to meet our voluntary Clean Energy Vision environmental stewardship goals, we will need to Think beyond. Be bold by investing in innovative solutions and technologies like the Columbia Energy Storage Project. The proposed project in Pacific, Wisconsin, is a storage system that would be the first of its kind in the United States.
With an innovative design by Energy Dome, the system stores energy by compressing carbon dioxide (CO2) gas into a liquid. When we need that energy, the system converts the liquid CO2 back to a gas, which powers a turbine to create electricity. This highly efficient, zero-emissions, closed-loop battery system can power approximately 20,000 Wisconsin homes for 10 hours on a single charge. Pending approval, we expect the system to be operational by the end of 2026.
Additionally, to advance innovation in infrastructure (SDG 9) we made use of federal funding opportunities, and the United States Department of Energy awarded the project a $30.7 million grant. Through collaborative and innovative practices, the Columbia Energy Storage Project represents a significant advancement toward a more sustainable, reliable, cost-effective and clean energy (SDG 7) future.
