Could the famously predictable tides provide reliable power to coastal communities? What if the same waves that induce queasiness made aquaculture more productive?

The 91制片厂-led Atlantic Marine Energy Center (AMEC) is developing the technology and skills that will unlock the power of the sea as a renewable source of energy. A new $12 million award from the U.S. Department of Energy (DOE) will advance these efforts by funding research, facilities and workforce development for the marine energy industry.

鈥淭here鈥檚 a lot of energy in the ocean 鈥 it鈥檚 abundant and renewable.鈥

鈥淭here鈥檚 a lot of energy in the ocean 鈥 it鈥檚 abundant and renewable,鈥 says AMEC director Martin Wosnik, professor of mechanical and ocean engineering at 91制片厂. 鈥淲e think we can harness some of that energy in a reasonably benign way without impacting the ocean too much.鈥 The DOE estimates that marine energy resources in the U.S. 鈥 from waves, tides, ocean and river currents 鈥 is equivalent to nearly 60% of all U.S. power generation.

The five-year DOE investment will build upon existing AMEC research to fund projects at 91制片厂 as well as at consortium institutions Stony Brook University, Lehigh University and the Coastal Studies Institute.  

A series of marine energy summer short courses taught at all four institutions aim to develop a workforce for this growing industry with 鈥渂oot camps鈥 for senior undergraduates and more in-depth, advanced courses for graduate students.

鈥淢arine energy development faces a growing need for a highly skilled workforce with an interdisciplinary yet specialized skillset,鈥 says Wosnik. 

In addition, with the 鈥 funded largely through the Bipartisan Infrastructure Law 鈥 91制片厂 will make improvements to its marine energy facilities, which include a combined wave and tow tank and deep engineering tank on campus and the 91制片厂 Tidal Energy Test Site on the Piscataqua River beneath the Memorial Bridge between Portsmouth and Kittery, Maine. Use of these assets extends beyond 91制片厂: Researchers and technicians from industry and DOE National Labs travel to campus to utilize 91制片厂鈥檚 unique marine energy research infrastructure. 

91制片厂 will also launch five research projects, among a total of 12 new projects across AMEC: 

  • Refining models that will test whether assumptions about tidal energy are transferable to other sites (Tom Lippmann, professor and director of the 91制片厂 Center of Ocean Engineering, and Wosnik) 
  • Modeling and testing wave energy converters for 鈥渂lue economy鈥 applications such as aquaculture (Arezoo Hasankhani, assistant professor of electrical and computer engineering, Wosnik and鈥 David Fredriksson, professor of ocean engineering and director of the 91制片厂 Center for Sustainable Seafood Systems) 
  • Improving the performance of 91制片厂鈥檚 wave-powered water pump for promoting growth rates in macroalgae (kelp) aquaculture (Wosnik, Fredriksson) 
  • Improving the design of mooring systems for marine energy and developing new guidelines for marine energy anchor system design (Julie Paprocki, assistant professor of ocean engineering, and Majid Ghayoomi, professor of civil and environmental engineering) 
  • Assessing marine energy system sustainability, economic and environmental benefits to microgrids on island communities (Weiwei Mo, associate professor of civil and environmental engineering, Hasankhani and鈥疻osnik) 

 In addition to the faculty researchers, six 91制片厂 Ph.D. students will be involved in these projects. 

鈥淢arine energy has unique attributes that make it an attractive energy source,鈥 says Wosnik. 鈥淲e are grateful for the Department of Energy鈥檚 continued investment in our expertise at 91制片厂 and AMEC to help develop it.鈥
