PVS Chemicals, Inc. (PVS) is partnering with Energy Systems Group, LLC (ESG), a leading sustainable energy solutions provider and wholly owned subsidiary of CenterPoint Energy, Inc., to significantly improve sustainability at its sulfuric acid plant, located in Chicago, Illinois. The companies plan to do this by capturing waste steam to generate 2.6 MW of renewable electricity through a steam turbine generator in the new onsite Waste Heat to Power (WHP) Plant. The $14.2 million project, signed in June 2022, will generate renewable energy that is expected to cover approximately 95% of all plant electricity needs. The project should also eliminate over 12,700 tons of CO2 emissions per year, lessen utility interruptions from voltage trips, and reduce purchased water and chemical consumption.
Currently, a significant portion of this steam has no beneficial use. Using this steam to generate power onsite avoids the purchase of electricity from the grid, which has a high carbon and greenhouse gas (GHG) footprint. In total, PVS expects to reduce by 115% against the current carbon footprint associated with electric power.
