Officials from Danbury-based FuelCell Energy contributed to the clean coal discussion at the recent National Coal Council’s Annual Spring Meeting.  They highlighted the company's fuel cell carbon capture solution that captures carbon emissions from coal-fired power plants in an affordable way, while simultaneously producing power.  FuelCell Energy says about 70 percent of the smog producing nitrogen oxide in the coal flue gas is destroyed by the fuel cells.  Vice President of Advanced Applications & Technology Development Tony Leo told the gathering that the benefits are industry-changing from an environmental, economic and energy standpoint.
