The Advanced Research on Integrated Energy Systems (ARIES) platform, operated by the National Laboratory of the Rockies, provides laboratory capabilities for validating and testing marine energy technologies before they are deployed in ocean environments. Wave energy converters and related systems can be integrated with storage and hybrid generation assets, which represent emerging technologies that require thorough testing in controlled settings.
ARIES combines several specialized tools to replicate real-world conditions. The large-amplitude motion platform (LAMP) simulates ocean wave movements across six degrees of freedom, allowing researchers to test how wave energy converters physically respond to ocean conditions and measure their energy-capture performance. Complementary dynamometers at the facility validate power take-off systems by producing the rotational forces that drive electrical generation. Additionally, grid emulators replicate power system integration, enabling researchers to test how marine energy devices interact with various configurations of batteries, electrolyzers, and other grid-connected systems.
The platform addresses a significant need for remote and offshore applications. Hundreds of microgrids across U.S. coastlines and islands have limited or no connection to the main electrical grid, creating potential opportunities for marine energy solutions. These applications include powering autonomous underwater vehicles, supporting ocean sensing and aquaculture operations, and providing electricity to isolated communities and military bases. Testing marine energy systems at ARIES before deployment helps confirm their long-term viability and technical performance.
Power electronics represent a critical focus area at ARIES, as wave energy produces variable and unsteady power that must be converted and filtered for reliable grid use. The facility has validated systems such as the hydraulic and electric reverse osmosis wave energy converter (HERO WEC), where researchers developed improved charge controllers to manage energy flow between offshore generators and onshore batteries. The National Laboratory of the Rockies has also launched educational webinars and established partnerships with Department of Energy programs to help communities and companies integrate marine energy into their microgrid infrastructure.
