A Hybrid Wind-Hydrogen System (HWHS) can perform energy arbitrage to maximise revenue, i.e. produce electricity when the tariff rates are high and hydrogen when the tariff is low. Another operational strategy can be to maximise the production of green hydrogen. 

When making HWHS investment decisions, the operational objective impacts the optimal sizing of the wind turbine, electrolyser, and hydrogen tank. Zheng et al. (2022) demonstrate this using a multi-objective HWHS optimisation that considers both the investment phase and the operational strategy. But while there is an optimum investment strategy for each operational objective, Zheng et al. (2022) suggest that it may be helpful to design for flexibility as the system’s operating strategy is likely to change throughout its lifetime.
