Green Gas Grid Injection

Project Description

To increase the sustainable development and reduce the environmental footprint, Penare farm in Higher Fraddon, United Kingdom, decided to invest in a biogas plant. An anaerobic digester converts organics material including local food waste and agricultural waste, into gas and electricity. Gas is fed into the national grid and to a local CHP to produce heat and electricity, ensuring proper operation of the plant. Per hour 450 Nm³ raw biogas is upgrade to 250 Nm³  biomethane. Equivalent to the consumption of natural gas by 2000 households.

DMT Environmental Technology supplied the biogas upgrade installation, to export the Green Gas to the national grid and fuel the CHP installed on site. For this project, CSH delivered an oil injected rotary screw compressor package, which we installed in DMT’s biogas upgrade enclosure.
