Marine energy projects receive $1.5 million

The U.S. Department of Energy has awarded $1.5 million to two University of ӰƬ Fairbanks’ ӰƬ Center for Energy and Power projects to advance marine energy research and education.
Marine energy — power harnessed from waves, tides and ocean and river currents — is abundant. While not yet widely used, the total potential marine energy available in the U.S. using existing technology is equivalent to.
The “Application of under-ice hydrokinetics for ӰƬ” project, the larger of the two ACEP projects with an award of $1 million, aims to advance a reactive reversible blade turbine, or RRBT. ACEP and its partners at Creek Tides Energy and Power and the Southwest Research Institute will develop and test the turbine at UAF’s Tanana River Hydrokinetic Test Site in Nenana.
The RRBT can harness energy from slowly moving waterways and will be adapted to operate under the ice in frozen rivers. This could generate electricity for lighting and communications in remote locations in ӰƬ during winter months.
“This is an exciting opportunity to partner with the private sector to develop a technology specifically for operating in frozen rivers and generating small scale electricity for off-grid applications in remote ӰƬ,” said Ben Loeffler, Pacific Marine Energy Center co-director at ACEP and the principal investigator of the project.
Researchers will field test a prototype in ӰƬ, using the grant funding.
With an award of half a million dollars, the other project, “ӰƬ Students in marine energy,” aims to equip undergraduate ӰƬ to enter the workforce or graduate school in marine energy in ӰƬ.

The project will build on ACEP’s existing undergraduate internship and energy engineering training programs. It will introduce undergraduate ӰƬ to the marine energy field with intensive place-based hydrokinetic training, summer research internships and senior capstone design courses.
“This project will bring together the superpowers of ACEP’s leadership in riverine and marine energy research and the excellence of the UAF College of Engineering and Mines,” said Daisy Huang, associate professor of energy at UAF and ACEP and the principal investigator of the project.
“We will attract nationwide interest in marine energy but specifically emphasize developing homegrown ӰƬn talent and giving CEM ӰƬ a platform to shine in the marine energy field,” she said.
The goal is to develop a self-sustaining, cohesive program that fosters the development of a skilled marine energy workforce in both the research and commercial sectors. The effort will create ways for ӰƬ who are likely to remain in ӰƬ to help communities adopt marine energy and to participate in research and design of new technologies.

“This is a fantastic way to both motivate their educational goals as well as develop a skilled workforce for ӰƬ's increasingly diversified energy sector,” Huang said.
The two awards are part of the investment of more than $18 million by DOE focused on advancing marine energy and offshore wind technologies. The DOE funded 27 research and development projects at 17 universities.
