Abstract
A biogas collection and purification system that includes a plurality of sources of biogas and a network of conduits configured to convey the biogas from the sources to a central processing facility for processing the biogas into methane. The central processing facility removes impurities to convert biogas to biomethane and may include an H2S removal stage; an activated carbon scrubber; a gas drier; and a carbon dioxide removal stage. The facility also has a biomethane gas compressor configured to deliver the biomethane for use in power plants, for CNG production. Ancillaries to the system include fuel cells for direct electricity generation from biogas/biomethane.
Claims20
A method of managing biogas production, the method comprising:
- receiving, at a central processing facility, biogas from each of a plurality of remote biogas sources, wherein each of the plurality of remote biogas sources are connected to the central processing facility by a network of biogas aggregation conduits;
- processing the biogas to form processed biogas;
- providing, to one or more targets, a controlled amount of the processed biogas based, at least in part, on a predicted amount of the biogas available at each of the plurality of remote biogas sources and biogas hold-up present in the network of biogas aggregation conduits.
