So far it looks like building a Green Thermal Utility in Saint John to cool and heat uptown buildings with ocean water is feasible. The system of sucking up and storing water from the Bay of Fundy in a thermal unit would be the first of its kind in North America. Managing Director, David Stewart says the payback period for a centralized system would be about 10 years.
Stewart says there may be significant funding available through both federal and provincial programs if the project moves forward. Saint John could be cooling and heating five of its uptown buildings with seawater by 2012. The feasibility study is expected to be complete by years end, along with a detailed technical concept and piping installation as well as heat exchangers.
