GreenGas Resurrects Two AMM Projects in Germany
Green Gas Germany has announced the acquisition of two AMM to energy projects, 20 kilometers west of Dortmund in the northern Ruhr region. The installations, first operational in 2004, drain methane from mines closed in the 1980s. The methane is used to power combined heat and electricity production (CHP), with a total estimated installed capacity of 2 MW electrical power.
The CHPs at the Lothringen site are currently shut down because of low methane concentrations, but Green Gas Germany plans to restart production with patented technology that can utilize coalmine gas with methane contents below 20%. When fully operational, both sites where mitigating more than 5 million m3 AMM annually. Both projects benefit from the attractive German Renewable Energy System, which guarantees stable electricity prices for a time frame of 20 years.
