Methane Energy Generation Project Phase 4

This project aims to build off the previous design (WA-RD 901.1) to create an energy recapture and generation system applicable to the Safety Rest Area’s (SRA) or other public facilities operated by the Washington State Department of Transportation (WSDOT). This system uses methane generated in the wastewater conveyance process to create electrical energy to run the SRA with the possibility to send excess electricity to the grid. This project revolves around two high-priority problems: (1) reduce greenhouse and prevent harmful gas release into the atmosphere, and (2) quell operational and capital costs at SRA’s while fulfilling regulatory requirements. Currently, methane, as well as other environmentally impactful gasses such as hydrogen sulfide (H₂S) and carbon dioxide (CO₂), escape into the atmosphere without treatment at the sewer facilities located at Safety Rest Area’s (SRA) that are operated by the Washington State Department of Transportation (WSDOT). Utilizing sewer system gases at SRA’s could potentially allow for significant operational cost reductions for WSDOT, as they maintain and operate numerous facilities, as well as reducing greenhouse gas emissions.
