Captured Landfill Methane (CLM)
Our CLM Division generates baseload renewable power from across 122 sites through the extraction and combustion of CLM, a naturally occurring gas from the decomposition of organic matter contained in the waste of landfill sites. The generation of power from landfill gas abates the impact of methane emissions on climate change as well as providing an efficient and secure source of local power generation.
A network of pipelines and gas wells are installed on the landfill site allowing the management and collection of the gas. The gas is delivered into the gas utilisation compound where reciprocating engines use the extracted gas as a fuel source, converting thermal energy into mechanical power and electricity. These engines are reliable and well-suited for CLM generation, with the majority being containerised which allows for easy relocation. This enables us to match the engine capacity to the available gas on site and allows us to optimise our engine overhaul strategy.
