Powerspan’s history dates back to 1994 when co-founders S. Edward Neister, a physicist; Nathaniel M. Johnson, an electrical engineer; and Frank Alix, a nuclear engineer with experience in venture investing, founded Zero Emission Technology Inc. The company’s initial product was designed to improve the performance of a power plant’s existing particulate control equipment.

As we grew, our technology evolved into an integrated multi-pollutant control process, in anticipation of requirements related to the Clean Air Act. Reflecting our focus on next generation clean energy technology for the electric power industry, Zero Emissions Technology became Powerspan Corp. in 2000.

Since then we have field tested our multi-pollutant control technology, which we now offer commercially. Since 2004, we have been developing and testing a carbon capture process for power plants and today, we are considered a leading provider of carbon capture technology.

The timeline below chronicles our history and highlights significant company, technology, and partner milestones.
