Technology Description:

The Ocean Renewable Power Company (ORPC) will develop an innovative, self-deploying MHK power system, which will reduce the operating costs and improve the efficiency of MHK systems by up to 50%. ORPC’s system is based on pitch control of the blades of a cross-flow turbine, in which the tidal flow passes across the turbine blades rather than in a radial fashion. This system will allow the turbine to self-propel itself to the deployment location, and lower itself to the sea floor remotely. This innovative approach will allow for lower costs of deployment and retrieval, reduced requirements for sea-bed foundation construction, as well as increased turbine efficiency. The ORPC team will design, build, and test a model scale of the MHK system to demonstrate the benefits of using a self-deploying turbine, before completing the design and cost analysis of the full-scale commercial system. Successful deployment of this system would significantly reduce the LCOE associated with MHK systems, making the technology a viable renewable resource to generate electrical power.

Potential Impact:

If successful, the ORPC's innovations could reduce operations and maintenance costs for a typical MHK project by a factor of 2 and increase its energy efficiency by up to 50%.


Increased utilization of renewable energy resources could improve grid resiliency by having more power generation options available.


Greater use of MHK systems could lessen use of fossil-fuel based power and reduce CO2 emissions.


This project will foster a U.S.-led industry in marine hydrokinetics by overcoming maintenance and operations costs that contribute to the current high LCOE associated with MHK systems.
