biogasCo-Energy Canada uses our same power-plants, used in conjunction with anaerobic digesters, for biogas CHP. Utilizing bio-gas serves two important purposes. First, the system provides a societal benefit by converting unwanted waste to a valuable gaseous fuel consisting of approximately 55% methane and 45% carbon dioxide. In the case of dairy applications, the biogas cogeneration plant also rids the environment of a greenhouse gas pollutant that is twenty times more harmful than carbon dioxide. Second, the biogas fuel is used to generate clean, cost effective power in a system that is qualified to operate under strict air quality requirements for NOx, CO and VOC’s.

Anaerobic digesters operate on the principle that bacteria, in the absence of air (anaerobic), can convert organic matter to methane and carbon dioxide. The process works best when the waste slurry is heated. For dairy manure the desired temperature is approximately 38C while crop waste requires a temperature near 57C. Heat to the anaerobic digester is provided by the power-plant engine’s water jacket with no additional fuel consumption.

Our Biogas CHP units features a family of MAN natural gas-fired reciprocating engines that have been specifically engineered and modified for lower heat content fuel. They have compiled decades of efficient, reliable operation, (mainly in Europe) using these biogas fuels. The biogas CHP units have been further improved to increase the time between routine maintenance and to maximize the amount of heat made available. This heat is sent to the anaerobic digester from the engine’s jacket to maintain digester effectiveness and reliability.
