temporalEnbridge Inc. is emerging as major corporate venturing partners in the Canadian cleantech scene. It has already acquired more than $3 billion in renewable energy assets — a combination of solar, wind, geothermal and run-of-river hydro. It has invested in concentrated solar PV manufacturer Morgan Solar and hydrogen tech firm Hydrogenics. It has pursued innovative waste-heat capture at its compressor stations in combination with fuel cell technology. Now, it is throwing its financial support behind flywheel storage innovator Temporal Power.

Temporal, based in Mississauga, Ontario, announced this week it has completed a $10 million Series B equity financing, with Enbridge Emerging Technology Inc. one of the lead investors along with Northwater Intellectual Property Fund (which was also lead investor in the company’s Series A financing in July 2011). Northwater Capital, it should be noted, is the money behind NRStor, a company with plans to develop Canada’s first energy storage park. NRStor, using Temporal Power flywheels, has already won a contract with Ontario’s Independent Electricity System Operator, which will see the flywheels being used to provide regulation services on the provincial grid. Annette Verschuren, former CEO of Home Depot Canada, is heading up the NRStor initiative.

Temporal Power describes its flywheel technology as a  ”quantum leap forward” because of its capability of storing 50 times more energy than most flywheels and enabling a power output that is five times higher per unit than its nearest grid-scale competitor. “Using its proprietary flywheel energy storage technology, Temporal Power’s scalable power storage plants offer utilities and power generation companies the ability to deliver efficient and cost-effective fast response capabilities for balancing energy and improving power quality on the electrical grid,” the company said in a statement.
