How does it work?
Infinis’ focus is on electricity generation from landfill gas (LFG) and LFG management. LFG is one of the naturally occurring products of decomposing organic matter in landfill sites. Methane comprises around 60% of LFG which is one of a number of gases which contribute to global warming. Methane is a highly potent greenhouse gas with a contribution to global warming which is over 20 times greater than that of carbon dioxide.
Infinis extracts the gas by sinking wells into the landfill site. The gas is then drawn into the well head and flows into a network of gas collection pipes. These wells are monitored on site and by real-time reporting to track the volume and composition of the LFG collected.
Conversion into electricity
The gas plant centrally collects the LFG from a network of pipes and removes the moisture. Gas composition is monitored on an ongoing basis. The LFG is then burnt in a gas engine which drives an alternator and electricity is generated.
Feed into grid
The electricity is then fed into the electrical distribution network (National Grid). The proximity of landfill sites to populated areas enables efficient energy transfer, reducing transmission losses and easing grid capacity problems. This is why Infinis is essentially an embedded generator.
The generation of power from LFG therefore abates the global warming impact of the methane emissions as well as providing an efficient and secure source of local power generation.
