On April 30, the Department of Energy announced that it would provide up to $13 million for approximately 10 marine and hydrokinetic (MHK) energy system projects. Eligible projects must either attempt to increase the power-to-weight ratio of a system or attempt to improve system reliability. The funding opportunity has three different aspects: advanced controls, next-generation power take-offs, and optimized structures. Up to six advanced control projects will receive between $500,000 and $2 million each; these projects must optimize energy capture and system load. Up to two next-generation power take-offs projects designed to improve system reliability will be awarded $3 million each. Up to two optimized structure projects will be awarded $1 million each; these projects must attempt to mitigate extreme condition risks. Those interested in applying must submit a letter of intent by May 13.
