The environmentally friendly system will increase municipal revenues, reduce landfill wastes and lower greenhouse emissions by nearly 5.5 million tons annually, while decreasing the city’s energy costs by about $800,000 a year. The system includes a 900-kilowatt fuel cell power plant, manufactured by FuelCell Energy (NasdaqNM: FCEL), that will generate electricity without combustion using methane, a biogas produced naturally on site by the organic materials contained in wastewater.

Small-scale cogeneration in Europe may be more widely applied than previously assumed, according to the ‘COGEN Challenge’ project team, which has registered the 500th cogeneration unit on its on-line database. Policymakers should therefore be more confident in the promotion of cogeneration and include it as a central part of their energy planning, says the team.
