The National Renewable Energy Laboratory (NREL) in Golden, Colorado, conducted a study supported by the U.S. Department of Energy's Water Power Technologies Office (WPTO) to evaluate the potential of tidal energy in Alaska's Railbelt region. The study focused on the Cook Inlet, which holds significant tidal energy resources and flows into the Railbelt grid serving a large portion of Alaska's population. Tidal energy systems were identified as a predictable and renewable energy source that could help balance the grid with its unique generation patterns. By developing a power systems model, researchers estimated that the Cook Inlet could potentially generate up to 300 megawatts of tidal energy, offering a sustainable power source for cities like Anchorage. The study also emphasized the environmental benefits of tidal energy, highlighting its ability to reduce carbon emissions by up to 37% and exceed the current electricity consumption of the Railbelt grid. Moreover, the excess energy generated could be utilized for producing clean fuels like hydrogen or ammonia, presenting economic opportunities for Alaska. The research outlines a positive outlook for tidal energy's integration into the power grid, projecting it to fulfill a significant portion of the Railbelt's electrical demand by 2035. This collaboration between NREL and local utilities aims to pave the way for a greener and more sustainable energy future in Alaska's Railbelt region.
