Clarke Energy to supply Gas-fired CHP and Gen-set to Biogas development in Maine
Biogas producer Peaks Renewables has contracted Clarke Energy USA to supply a natural gas fired combined heat and power (CHP) system and a 500-kW Kohler Power backup gas generator.
The CHP system will deliver 280 kW of electricity and approximately 1.5 MMBtu of thermal energy, which will be used to process hot water at a biogas plant in Maine, where Peaks Renewables has partnered with the dairy industry to produce renewable natural gas at an anaerobic digestion facility using cow manure. The high efficiency of the system will help reduce carbon emissions and save fuel costs.
“Our anaerobic digestion facility will enable us to treat farm waste sustainably and in parallel generate renewable natural gas which will help to reduce carbon emissions,” Ryan Morris, Peaks Renewables said. “We selected Clarke Energy to supply both our CHP plant and back up gas generator to deliver fuel efficiency and resilience to our operations.”
Bright Future with Many Energies: Kohler leader details Microgrid, Biofuel efforts
In the digester, owned and operated by Peaks, the manure will be heated and decomposed to create biogas. This gas will be refined to pipeline quality and the renewable energy credits will be sold to third parties. The natural gas will be purchased by Summit Natural Gas of Maine.
The CHP system will also have a black start capability, enabling restoration of electric power without the need to rely on an external electric power transmission network. The CHP system, together with the KOHLER generator will ensure energy efficiency and resilience for the project.
Clarke Energy, which is owned by Kohler Power, has completed several projects bringing gas-fired power to biogas and biomass facilities. Recently, Clarke worked with LMS Energy to supply it with a 1.1-MW Jenbacher biogas engine installed at a landfill site in Brisbane, Australia.
