Power-to-gas to meet transportation demand while providing ancillary services to the electrical grid

Power-to-gas is a versatile and effective form of energy storage by which electrolysis generates hydrogen. The produced hydrogen thus becomes an alternative energy vector, which can be contained within the natural gas infrastructure or other storage medium. By means of the rapid response of polymer electrolyte membrane (PEM) electrolyzers, Power-to-Gas is also able to offer important and high value auxiliary and regulatory power services, as well as energy transformation. In this paper, the authors use the General Algebraic Modeling Simulation to develop a simulation of a 2MW Power-to-Gas system that produces hydrogen to meet the demand of a hydrogen fueling station, while providing ancillary service to the electrical grid.
