An integrated wind-hydrogen plant model with energy storage is developed. • A multitude of plant configurations were considered in a liberalized electricity market. • Optimum electrolyser and battery sizes – 3496 kW × 81 units and 360 MWh (60 units). • Minimum H 2 cost achieved varies from $3.37/kg H 2 – $9.00/kg H 2.

At present, the types of large-scale energy storage system in commercial operation have only pumped hydro energy storage (PHES) plants and compressed air energy storage (CAES) power plants. Mechanical energy storages, characterized by low energy storage density, is the basic property of PHES and CAES plants [3] .
