A sewage heat station or a biomass plant placed near the Marine Drive SkyTrain station are two suggested options for a $100-million plan to green the Cambie Street corridor.
According to Chris Baber, the City of Vancouver's neighbourhood energy manager, a study found those two options as potentials for the plan, which aims to replace all heating boilers in the corridor with a network of heated water pipes pumped out by the proposed south Vancouver plant. Boilers are expected to be switched out as they expire.
A sewage line currently runs directly underneath Cambie, and heat generated by that line could be converted at a plant to potentially feed the entire corridor. Another option is a biomass plant, which would burn or gasify wood waste to generate heat.
Both options could potentially reduce 80% of existing emissions, Baber said.
The funding should be recuperated through heating bills, Baber said, and he expects the project to be completed around 2016.
