Tidal Energy Could Cover 57% of US Electricity Demand, NREL Study Finds
Exxon and Chevron’s $26.5 Billion Quarter Draws Trump’s Ire REalloys is establishing a comprehensive,… Haley Zaremba is an energy journalist and researcher with more than a decade of professional experience covering global energy systems, land and natural resources, and… An Alaska-based tidal energy company is testing a new kind of small, modular turbine in the waters off of Massachusetts to try to take advantage of the United States’ vast and untapped tidal power potential.
The turbine is being piloted in the strong tidal currents of Cape Cod to test the technology’s performance and durability in real-world conditions in order to explore whether it could be suitable for commercial scaling.
Tapping into the country’s tidal energy potential could be a major game changer for decarbonization and energy security in the United States.
In 2021, the National Renewable Energy Laboratory (NREL) found that the total energy potential of marine sources in the United States amounts to approximately 2,300 terrawatt hours per year, or 57 percent of the whole country’s electricity output in 2019.
As such, “even if only a small portion of the technical resource potential is captured, marine energy technologies would make significant contributions to our nation’s energy needs,” thereportfound.
Despite the country’s vast tidal energy potential, the United States currently haszero commercially operating tidal power plants.
The model currently being tested in the tidal canals of Cape Cod could therefore be an important first step toward tapping into this vast clean energy potential and bringing the technology one step closer to becoming a commercial reality.

Most tidal energy prototypes are large models affixed to the sea floor.
The model being tested at the Marine Renewable Energy Collaborative’s (MRECo) Bourne Tidal Test Site (BTTS) is much smaller and modular, which could lend itself to simpler installation, scaling, and maintenance for potential commercial applications even in remote coastal communities.
This testing site is small-scale and exploratory in nature, but could create valuable data for future tidal energy research and design.
“Our goal is to make marine energy easier to build, deploy, and maintain in remote areas,” Lance McMullan, Sitkana founder and CEO, was recentlyquotedby Interesting Engineering.
