The science of capturing gas from wastewater treatment plants to be used as fuel for vehicles and generators has been well developed. However, some utilities are turning to fuel cells to produce electricity directly from biogas — without relying on combustion.Fuel cells operate on the same principle as common batteries used in consumer electronics. Batteries create an electric current when charged particles move between two dissimilar materials — for example, nickel and cadmium — through a medium known as an electrolyte.The Direct FuelCell offered by Connecticut-based FuelCell Energy works by converting methane to hydrogen and carbon dioxide using a nickel-based
