System and method for renewable energy based EV charging and hydrogen fueling

A system for electric vehicle charging and hydrogen fueling at a charging station located at a renewable energy microgrid, the system comprising:

• an electrolyzer that receives power by excess energy generated by a renewable resource of the renewable energy microgrid, and operates to produce hydrogen gas from water, wherein the renewable energy microgrid operates independently of a central grid;
• a compressor that receives power by the energy generated by the renewable resource of the renewable energy microgrid, and operates to compress the hydrogen gas;
• one or more pressure vessels that store the compressed hydrogen gas;
• a hydrogen fuel dispenser of the charging station that receives supply of at least a first portion of the compressed hydrogen gas from the one or more pressure vessels for fueling a fuel cell electric vehicle at the charging station;
• a fuel cell that receives at least a second portion of the compressed hydrogen gas from the one or more pressure vessels, and operates to generate electricity based on the at least second portion of the compressed hydrogen gas;
• and
• an electric vehicle charging dispenser of the charging station that receives supply of the generated electricity for charging a battery of a battery electric vehicle at the charging station.
