Opportunity of Hydrogen Production in Renewable Power Plants: Case of Island of Mauritius

Excess power is an inherent feature of renewable energy systems where the produced renewable energy exceeds the demand load and the storage systems are fully charged. In contrary to the grid-connected renewable systems where the excess power is feed into the grid, in case of standalone system the excess power is either dumped or used for green hydrogen production. This paper presents a heuristic size optimisation algorithm for the sizing of water electrolyser which minimises the levelised cost of hydrogen production. The algorithm is used to investigate the potentials of using the excess power of PV-battery system designed for Island of Mauritius for hydrogen production.
