Abstract
One of the main advantages of fuel cell based mobility over other sustainable mobility
concepts is the flexible production of hydrogen via electrolysis. To date, it is unclear how
electrolysis at hydrogen refueling stations should be operated in order to achieve the
lowest possible costs despite the constraints of hydrogen demand. This study proposes and
evaluates an intelligent operating strategy for electrolysis capable of exploiting times of
low electricity prices while participating in the spot market and maximizing wind energy
utilization when combined with a wind farm. This strategy is based on a simulation model
considering imperfect forecasts (e.g. of wind availability or energy prices) and non-linear
electrolyzer behavior. Results show that this approach reduces hydrogen production
costs by up to 9.2% and increases wind energy utilization by up to 19%, respectively.
