The biogas cogeneration plant allows the simultaneous production of electricity (CHP or cogeneration) and heat (hot water or steam). The electricity can be used to power the surrounding equipment or injected into the national grid. CHP maximises the fuel and converts it into electricity with 35% efficiency and into heat with 50% efficiency.
CHP is well suited for commercial applications at hospitals, nursing homes, laundries, and hotels where hot water demand is high. CHP can be used as well at institutions, such as colleges and schools, prisons, and residential and recreational facilities.
The French Energy Transition Law sets a target of 10% of gas consumption and 40% of electricity from renewable energies by 2030.
Since December 13, 2016, a decree fixes the new rules for the electricity feed-in tariffs generated from methanisation, which has helped reassure potential investors. It is more suited to the current economic realities.
For installations with a maximum electrical power of 80 kW or less, the resale tariff is 0.175 € / kWh. For installations with an electrical power between 80 kW and 500 kW, the tariff is 155 € / Mwh. Farmers are also entitled to a premium of 0.05 € / kWh if they transform more than 60% of the residues from their activity. Starting at € 220,000, a farmer can now install a 22 kW power station on his farm. To achieve the objectives of the Energy Transition Law, the Government also decided, in February 2016, to extend the duration of electricity purchase contracts produced by methanisation from 15 to 20 years.
The biogas cogeneration plant has 3 main parts: biogas treatment, the engine and the control unit. The cogeneration specialist Cédric Colferai illustrates how it operates step by step, in a video published by Biogas Channel.
To know more about CHP technologies and performance features, read the Catalog of CHP Technologies published by the United States Environmental Protection Agency (EPA).
A biogas cogeneration system has two parts: one for the fermentation and production of biogas, which includes one or more fermenters, and the other to transform biogas into energy, which is the actual cogeneration system. Fermenters have a key role in the initial phase of biogas production, but energy performance and the overall financial performance of the factory depend upon the technological quality and solution of the cogeneration group. The ECOMAX® Biogas and ECOMAX® Landfill Lines have been designed to enhance biogas energy. The biogas siphoned into the Linea ECOMAX® modules allow production of electrical and thermal energy.

MTM ENERGIA customizes, manufactures and installs “turnkey” cogeneration plants with all the necessary components ready for testing. Systems do not consist of standard modules. Everything is sized and designed to meet the specific needs of each client.
Micro CHP plants supplied and installed by MTM Energia are small, lightweight and reliable. It is specially designed to improve the energy impact of small civil, industrial or commercial realities with significant energy consumption such as hotels, swimming pools, retirement homes, sports centers, small industries, etc.
The plant is delivered with everything and is placed in a special area made available by the customer. At this point the plant is ready to be connected to the electrical grid, to the fuel supply duct and to hot water connections. Each system is completely independent.

SYNGASMART® is a line of made in Italy micro-CHP systems, engineered and developed by RESET, for woody biomass Combined Heat and Power generation. These systems can be defined as thermoelectric machines based upon the pyro-gasification process, which can be briefly described as the use of high temperatures in an low-oxygen environment to covert woody feedstock (for example woodchips) into a synthesis gas called syngas. This fuel is composed predominantly of flammable gases such as hydrogen (H2), carbon monoxide (CO) and methane (CH4): through gasification, it is possible to convert nearly any dry organic matter into a clean burning fuel that can replace fossil fuel in most use situations.
Depending on the needs, the plants develop 30 kW, 49 kW, 50 kW, 60 kW, 100 kW, 120 kW.

The Cleanergy GasBox™ generates electricity and heat from biogas. The heart of the technology is the Stirling engine, first designed in the early nineteenth century. Now, with the advantage of modern manufacturing capabilities, this energy-producing technology is efficient, viable and proven.
The GasBox™ requires minimal-to-no gas cleaning which allows for small and mid-size wastewater treatment plants to achieve the power-generating benefits of biogas utilization. The GasBox™ can also run on biogas with a methane concentration as low as 18%, which alleviates the need at larger plants to burn off this biogas with a natural gas supplement.
