Biogas Cleanup System at Lulu Island Wastewater Treatment Plant

Construction will start this summer on a Biogas Cleanup System at Metro Vancouver’s Lulu Island Wastewater Treatment Plant.
This new system, which is expected to take 14 months to construct, will clean surplus, untreated digester gas (or biogas) to pipeline quality biomethane and inject it into Fortis BC’s natural gas grid.
In the wastewater treatment process, biogas is generated as a by-product. The biogas is used as a fuel for plant and process heating needs and any surplus biogas is flared. With the new Biogas Cleanup System, this surplus biogas is purified and sold to Fortis BC, and offered as a sustainable energy source.
Fortis BC will use the purified gas as part of its renewable natural gas program. The new system will employ a water scrubbing technology that is chemical free, self-contained, and environmentally friendly.
This project supports Metro Vancouver’s commitment to protect public health and the environment. This innovative treatment system will result in a decrease in the flaring of digester gas, a reduction in regional greenhouse gas emissions, and the reuse of a sustainable resource. The system will produce enough renewable natural gas to heat 400 homes and gas production will increase as our local population grows.
