As power generators across the world look toward renewable energies, the marine hydrokinetic (MHK) sector is quickly becoming an area of emphasis within the hydropower and larger renewable energy industry.

"There are clearly lots and lots of good ideas out there to harness hydrokinetic energy, but we also know cost reduction remains a major challenge," U.S. Department of Energy Secretary Ernest Moniz said recently. "That's exactly the kind of innovation we'd like to move forward in." We remain really strong in overcoming the scientific and technological challenge."
