In cooperation with our partner Evo Energy Technologies we supplied the CHP system. The custom-built 2G combined heat and power engine was the first of its kind within the South East Water network. The 2G cogeneration engine is a key tool in South East Water’s strategy to minimise carbon emissions and meet their Emissions Reduction Pledge by 2025.
 

The cogeneration engine helps South East Water meet roughly 40 per cent of the electricity demand at their Mount Martha WRP, requiring less coal-produced power from the electricity grid, and help the environment by minimising carbon emissions. The Mount Martha Water Recycling Plant has two anaerobic digesters that operate a biological process whereby organic matter is converted to produce biogas (predominantly methane). The 2G cogeneration engine uses all the biogas (as well as natural gas) to not only produce heat for the treatment process, but also electricity that can be used elsewhere in the treatment plant.
 

The 2G Cogeneration engine installed at the Mount Martha WRP is an agenitor 408 delivering an electrical output of 360 kW. The unit is installed in a 9.0m x 3.0m x 3.2m Super Silent (45dBa at 10m) Highline Container module, with two tank Activated Carbon biogas scrubbing systems for removal of H2S and siloxanes and a H2S Gas Dehumidification System.
