Method and apparatus for generating green electrical power. During a hydrogen gas storage mode, an electrolyzer generates a stream of hydrogen gas from water supplied by a water source and using power from an input power source. A hydrogen tank temporarily stores the stream of hydrogen. During a power generation mode, a fuel cell converts the stream of hydrogen gas from the tank into output electrical power by combining the hydrogen with oxygen. An inverter conditions and supplies the electrical power to a local load. A controller circuit uses a system parameter to adaptively switch between the storage mode and the power generation mode. In some cases, external power is supplied during the generation and storage of the hydrogen gas from an electrical grid or a local renewable source such as a set of solar panels. Respective grid-tied, solar-tied, grid-only, off-grid, and electric vehicle charging configurations are provided.
