Innovative `Wave Energy' Project Announced
DEEP RIVER, Conn., Sep 7, 2004 (BUSINESS WIRE)
Energetech America LLC today announced plans for a "first of its kind" wave energy project in the United States. Planned for an area more than a mile off the southern coast of Rhode Island, "GreenWave Rhode Island" is an estimated $3.5 million project to convert ocean waves into clean electricity.
The pilot project, planned to operate for three years, has received $1 million in planning and development funds from the renewable energy funds of three New England states (Rhode Island, Massachusetts and Connecticut). Company officials said the facility is planned as a not-for-profit operation intended to demonstrate the commercial viability of its wave energy technology. Research for the project is being conducted by the University of Rhode Island (URI), world-renowned for oceanographic science and education.
Energetech has developed a unique technology using an "oscillating water column" (OWC) as a key component. For two decades, the OWC has been the world's foremost wave energy technology, demonstrating proven results in numerous projects. Energetech's technology enhances OWC's commercial viability. In brief, the up-and-down movement of waves forces air to rush into a hollow chamber where it is compressed, turning a turbine and powering the generator. The structure, with its four legs resting on small pads on the ocean floor, is stabilized by cables moored to the seabed.
Plans call for electricity to be transmitted via a cable under the seabed to an existing transmission line on the mainland, where it interconnects with the New England power system. GreenWave Rhode Island will produce up to 500 kilowatts of electricity, enough to power approximately 300 average households.
"The impact of traditional power plant emissions on air quality and climate combined with dwindling supplies of fossil fuels make it imperative that government and industry accelerate the development of clean, 'green power' technologies," said Janice McClanaghan, Director of the RI State Energy Office. "If approved, this project presents an opportunity for developing a promising and abundant renewable resource."
"Moving America forward on a path toward greater energy independence that will create new jobs and lead to a healthier environment cannot be achieved by the work of a single state," said Rob Pratt, Director of the Massachusetts Renewable Energy Trust. "We are proud to participate in this multi-state coalition working to advance wave energy technology, which has enormous potential to help us build a cleaner energy future."
Dr. Denniss said the keys to a successful project include a favorable wave climate, proximity to the area's electric power system, and suitable bathymetric conditions (contour of the ocean floor). The company examined the waters off New England's four coastal states and found the Point Judith, Rhode Island, area ideally suited for the project. Based on URI research, the best location is a quarter-square-mile area more than a mile from the mainland. URI researchers are analyzing that area to help identify the best spot for the project.
The structure will measure approximately 100' X 120' X 40' high above the water surface. It will be designed by internationally renowned marine engineers according to a rigorous marine engineering design code to withstand the area's sometimes severe storms. Denniss said a visual study by an independent environmental company confirms that the distance of the project from shore will make it barely visible from most locations. Plans call for the structure to be fabricated in Rhode Island and floated to the site, where installation will take about one week.
Dr. Denniss, an expert in oceanography and ocean energy systems, said the project will preserve marine life and not interfere with recreational or commercial uses of coastal waters. Energetech expects to submit an application with state and federal permitting authorities late this year. Green- Wave Rhode Island must undergo a comprehensive review by state and federal permitting authorities to ensure it complies with environmental, navigational and other applicable regulations. The project is expected to being operations in 2006.
Later this year, Energetech is expected to begin operations at its Port Kembla, Australia project, which received government approval in 2003. Preliminary work is also underway on projects in Canada, Spain and other locations.
