InvestorsSales inquiry Recover & capture carbon FuelCell Energy’s scalable and affordable carbon capture solution captures carbon emissions from existing coal or gas-fired power plants, while simultaneously producing power. The solution is scalable so the amount of carbon capture can be increased over time. The fuel cells also destroy approximately 70% of the plant’s smog-producing pollutants. The capability to efficiently and affordably capture carbon while simultaneously producing power enables emission compliance in a manner that provides a revenue stream and returns on capital from the sale of power produced by the fuel cells. 123 Learn about our fuel cell carbon capture collaboration with ExxonMobil Fuel Cell Carbon Capture Television Ad Fuel Cell Manufacturing Video Manufacturing Tomorrow’s Energy- Energy Factor by ExxonMobil FuelCell Energy delivers efficient, affordable and clean solutions to enable a world empowered by clean energy.
