FIRM: GHD LIMITED
CLIENT/OWNER: METRO VANCOUVER
LOCATION: RICHMOND, BRITISH COLUMBIA
Metro Vancouver is exploring options for hydrogen production from their wastewater
treatment plants (WWTPs) to achieve carbon neutrality goals. Two pathways
were identified: electrolysis of purified final effluent and electrolysis of ammonia
recovered from digester supernatant centrate. The latter provides the additional
benefit of reducing nitrogen discharge to receiving waters.
GHD completed a study to assess the technical and economic feasibility of the two
hydrogen production pathways at the Lulu Island WWTP and developed conceptual
designs for both pathways. Evaluation included equipment, electricity consumption,
carbon intensity, GHG emissions, carbon credits and hydrogen end uses.
JUDGES’ COMMENTS
The feasibility assessment of two different pathways for green hydrogen
production at waste water treatment plants is critical foundational work
for accelerating the adoption of greener energy solutions.
This is a highly creative and innovative project, producing hydrogen
from municipal wastewater. It can generate a new circular economy of
waste to energy. Super interesting!
