Nova Scotia Power has partnered up with Dublin, Ireland-based OpenHydro Group to install a 1-megawatt tidal turbine to the seabed in the Bay of Fundy. It’s OpenHydro’s first installation of its 1-MW machine and is expected to be fully operational later this fall. Over two years the two companies will collect operational data, including impacts on environment, robustness of equipment, and power generation. The sub-sea base was manufactured by a local company in Dartmouth, Nova Scotia.

The OpenHydro turbine is one of three being tested under a Nova Scotia government pilot program, which aims to tap the immense tidal-energy potential in the Bay of Fundy. The Electric Power Research Institute has identified the Bay as one of the best — if not the best — sites in North America to develop tidal-energy projects. In fact, it’s capable of realistically generating 300 megawatts of tital power. U.K.-based Marine Current and B.C.-based Clean Current are the other two turbine concepts slated for testing.

I’ve often wondered about the wisdom of trying to co-locate offshore wind turbines with wave-energy technology as a way of saving on transmission-line costs and creating a capacity factor that’s much higher than the two technologies on their own. Back in July I e-mailed Francis Farley, inventor of the Anaconda wave power converter — basically a snake-like machine that captures the kinetic energy in the waves as its various segments bob up and down. I asked Farley what he thought about the idea of pairing his system with offshore wind. “You have a good point,” he said. “There would be some economies in combining offshore wind with wave energy, and some sites would have both.”

I dropped the idea, thinking it might be good fodder for a column at a later date. Then I noticed this week that Eric Stoutenburg, a researcher at Stanford University, came to a similar conclusion in a research paper that he presented this week at the American Geophysical Union’s fall meeting in San Francisco. “If wave energy wants to get off the ground, it might have better potential to develop in the shadow of an offshore wind plant,” Stoutenburg told Cleantech Group.

Finavera Renewables, a Vancouver-based wind and wave power developer, has enough troubles these days. The publicly traded company has shares trading at 5 cents and as an untested newcomer to the developer scene it’s considered much riskier than more established rivals when it comes to raising money, whether that be equity or debt. Not good when you’re staring in the face of the worst credit-crunch and financial-sector meltdown in at least a generation.

Nothing a prescription of Ativan can’t deal with, right? But then the California Public Utilities Commission comes along and nixes a wave-energy power purchase agreement between Finavera and Pacific Gas & Electric, which agreed to buy electricity from the Canadian company’s 2-megawatt wave project — the first commercial wave contract in the country, experts say. It was to use Finavera’s AquaBUOY technology, devices that turn the kinetic energy of vertical wave motion into emission-free electricity.

Greentech Media has the messy details here. The bottom line is that the commission declared the power-purchase price too high and the technology too unproven to proceed. Finavera has since put on a brave face, saying it will focus its efforts on projects under development in Canada and Ireland. But as nobel or attractive or economic any of those projects could be, the sad reality is that in this market at this time there’s not much wiggle room for setbacks.
