Wave Power Industry Buoyed by the Push for Renewable Energy - but Hurdles Remain
Submitted by Daniel Jarvis.
Wave power has been wanting for attention and capital, with most green and green eyes focused on biofuels, biomass bioenergy, solar and wind. Will wave power ever get its due? In the United States, the fact that the US Federal Energy Regulatory Commission (FERC) is proposing to shorten the permitting process for pilot ocean projects to as little as six months is a hopeful sign.
Harnessing the continual and limitless energy of ocean waves and currents into 100% renewable energy seems like an opportunity to good too be true. In Canada, while remaining a very promising prospect, wave energy projects face a daunting federal, provincial and even municipal regulatory and licensing burden, which has a significant commercial impact. There has also been relatively little federal or provincial support in the past for wave energy, compared to other renewable energy areas.
However, the tide seems to be slowly changing, with federal budget commitments in 2007 to renewable energy and changes to the Capital Cost Allowance (CCA) for businesses to allow a 50% accelerated CCA for eligible equipment (including some equipment that generates electricity using wave or tidal energy) on a straight line basis if purchased within the specified time period.
In BC, an Innovative Clean Energy Fund of $25 million was announced under the BC Energy Plan to help promising clean power technology projects succeed. Ocean (wave and tidal) energy projects are potential candidates of the Fund, but at this point are considered more of a future supply option with great potential, rather than an immediate commercially viable option.
The BC government estimates the cost of ocean energy production at $100 - $360 / megawatt hour, compared to $75 - $91 for Biomass and $700 - $1700 for solar. To test the waters, Canada’s first free-stream tidal power project has been installed at Race Rocks, located ten nautical miles southwest of Victoria, through a partnership between the Lester B. Pearson College of the Pacific, the provincial and federal government, EnCana Corporation and Clean Current Power Systems Incorporated. In addition, BC Hydro is developing a Standing Offer Program to acquire clean electricity from projects up to 10 MW, but it is believed that ocean energy projects will not be eligible at this point under the program which requires proven, commercial technology.
Industry is also moving forward on its own, despite the current regulatory hurdles. Finavera Renewables Inc. is proposing to operate a 5 megawatt wave power plant project off on the west cost of Vancouver Island in the District of Ucluelet. Finavera’s AquaBuOys would be moored several kilometres offshore and convert the vertical component of wave kinetic energy into pressurized seawater by means of two-stroke hose pumps. The pressurized seawater would be directed into a conversion system consisting of a turbine driving an electrical generator, and the power generated transmitted to shore by means of a secure, undersea transmission line. When operational, the 5 megawatt generator would produce enough electricity to power up to 1500 homes.
