Powerspan develops and commercializes proprietary, multi-pollutant control and carbon dioxide (CO2) capture technology for electric power plants.

Our technologies enable new and existing power plants to meet environmental requirements in a cost-effective manner. Our patented Electro-Catalytic Oxidation (ECO®) multi-pollutant technology provides high removal of sulfur dioxide (SO2), nitrogen oxides (NOx), oxidized mercury, and fine particulate matter (PM2.5) from coal-fired power plants, while our ECO-SO2 scrubbing technology provides equivalent multi-emissions control, but without NOx removal. Our ECO2 carbon capture technology is designed as an add-on system that can be deployed when needed.

We have commercially demonstrated our multi-pollutant control technology and have pilot tested our post-combustion carbon capture technology, both with successful results.

We continue to dedicate our resources to developing and commercializing advanced, clean energy technologies. As electric utility companies balance the need to produce affordable electricity with environmental requirements, we are uniquely positioned to provide the critical technology and expertise required to meet these challenges.

Powerspan is a Rockport Capital and Angeleno Group portfolio company.
