A system for generating electricity from an underwater stream for generating electricity for the electric grid or for producing hydrogen includes an underwater turbine. The underwater turbine includes an upper pontoon, a lower pontoon, and a pylon structure that extends between and interconnects the upper pontoon and the lower pontoon. The underwater turbine also includes a single propeller assembly rotatably coupled to the lower pontoon. Rotation of the propeller operates a generator to generate electricity. The underwater turbine can be moored to a sea floor via a mooring weight. An optional friction winch is operable to raise or lower the underwater turbine relative to the sea floor.
