The Marine Energy Technologies Acceleration Act aims to enhance the United States' competitiveness in marine energy technologies. The primary goal is to promote the development and deployment of marine energy sources, such as wave and tidal energy, to diversify the nation's energy portfolio and support economic growth. Key provisions of the Act include the establishment of the Marine Energy Acceleration Fund, which will receive billion to support various initiatives. This fund will finance at least twenty demonstration projects that connect marine energy systems to existing power grids.
