Ocean Renewable Power Company has received $2.248m from the US Department of Energy as part of the $125m set aside for 41 "transformational" energy technology projects.
The company will develop a deployment and retrieval capability that will reduce costs for cross-flow design marine hydrokinetic systems in which a turbine generates power from tides and/or rivers.
The turbine blades will employ active pitch control for thrust generation and gives better efficiency in power generation mode.
If the development is successful, it could lower the cost of the installation process. The turbine could be put in the water near the shore, self-propel to the deployment location, and hold itself in place on the seafloor through redirected downward thrust.
