Abstract:
An energy stand-alone supply providing electrical power to a load having an electrical power need using an energy supply source providing a source electrical power, wherein a time-variable discrepancy between said source electrical power provided by said energy supply source and said electrical power need, the energy stand-alone supply maintaining the provided electrical power between two pre-determined, the energy stand-alone supply comprising:a buffer receiving a source electrical power from an energy supply, the buffer further providing electrical power to a load according to an electrical power need of said load; a first power converter connected to said buffer and providing a converted electrical power using at least one part of the source electrical power in response to a first control signal; a hydrogen generator receiving said converted electrical power and generating hydrogen using said provided converted electrical power; a hydrogen storage storing the generated hydrogen provided by said hydrogen generator; a hydrogen conversion device receiving at least one part of said hydrogen of said hydrogen storage and providing a generated electrical power in response to a second control signal; a second converter receiving said generated electrical power and providing a converted electrical power of the generated electrical power to said buffer; a control unit providing said first and second signal, the control unit enabling the maintaining of the provided electrical power between the two pre-determined according to a control scheme.
