The Renewable Case Study looks at hybridizing a Wind plant with battery storage and hydrogen production for both storage and sales.
The simplest wind-battery-hydrogen plant is modeled as a wind plant with battery and a PEM electrolyzer in dispatches/renewables_case/wind_battery_PEM_LMP.py. The electricity flow from the wind is split among charging the battery, producing hydrogen via the PEM and selling directly to the grid. This model is built using the :ref:`windpower`, :ref:`battery`, :ref:`pemelectrolyzer` and :ref:`electricalsplitter` unit models.
The hydrogen can be used for power production as well, by adding the :ref:`hydrogentank` and :ref:`hydrogenturbine` unit models to the flowsheet. The conceptual design optimization code for this model is found at dispatches/renewables_case/wind_battery_PEM_tank_turbine_LMP.py.
