The 2G biogas CHP container module is a professionally designed technology package that features an MAN® cogeneration gas engine integrated into a unique biogas cogeneration system, which is specially developed for high-efficiency energy conversion of biogas. This plant can generate enough electrical energy to power approximately 8% of the University's energy requirements and the thermal energy is utilized to heat the digester, buildings, and other facilities within the University campus. Any excess power generated is sold to the grid. Compared to conventional gas engines, the 2G biogas CHP container module offers higher efficiency, reliability, durability, extended life, and lower maintenance costs.

 

The complete gas treatment, including cooler, dryer/dehumidification, and H2S removal system, was supplied by 2G Energy Inc. The customer also opted for the 2G Thermal Heat Distribution System that includes a Hydronic Junction to ensure that the CHP maintains optimal thermal performance in different load situations. This advanced technology decouples the primary heating source circuit from the secondary consumer circuit, thereby achieving consistent function in all operating states. The 2G THDA's provide the most energy-efficient heat transfer and allow for tighter temperature control due to the infinite system's ability to regulate temperatures gradually. The controls and switchgear, including utility interconnection, are also provided by 2G Energy. Additionally, 2G Energy installed a fully enclosed flare specifically designed for biogas applications. All of 2G's flare systems, vapor combustors, and solutions meet EPA regulation 40 CFR 60.18 and are BACT-approved.

This CHP cogeneration plant has been installed in Oshkosh, Wisconsin, supplying the University Campus with electricity and thermal energy. The University of Wisconsin Oshkosh decided to build their own dry fermentation anaerobic bio-digester. The first dry digester in the nation, converting food and yard waste into biogas. The renewable energy facility is designed by BIOFerm Energy Systems (Viessmann Group), a leading expert that delivers a wide array of turnkey energy solutions using biomass and organic waste as the primary feedstock. The combined heat and power plants utilizes the 2G patruus 370 rated 370 kW/h and a capacity of 3,071 MW p.a. Electrical Power and 474 kWh/th Thermal Power.
