Anthropogenic climate change is one of the greatest challenges that humanity faces today. While burning fossil fuels for energy has lead to many societal advancements, it has also released record amounts of carbon emissions into the atmosphere. To meet future energy demands and reduce carbon emissions, the continued growth in wind energy is imperative. However, wind's variability and transmission constraints limit how much wind energy we can harness. When the available wind power exceeds our ability to utilize it, that emission-free energy is curtailed. As more wind projects are connected to the grid, more curtailment is expected if there are no means to store that excess energy. Therefore, researching solutions to capture this otherwise forfeited energy can expand the capabilities of wind energy systems. Hydrogen has become an increasingly popular alternative fuel source to fossil fuels. Long-haul transportation, steel manufacturing, and commercial aviation are some heavy-emitting industries that cannot effectively exploit renewable wind energy. Therefore, producing hydrogen with water-electrolysis powered by renewable energy is seen as a path to decarbonize many hard-to-electrify industries. According to the International Energy Agency our hydrogen consumption is expected to double by 2030 as more industries transition from fossil fuels. Today, 95% of hydrogen is cheaply produced using fossil fuels making the transition to hydrogen seem fruitless. Modeling utility-scale green hydrogen systems may reveal new control-techniques or design-decisions that can help mitigate climate change by reducing carbon emissions from industrial sectors.This thesis analyzed wind curtailment as part of the system performance of a wind-hydrogen hybrid energy system. Through simulation, an adjustable electrolyzer was tested with time-varying wind conditions and feedback control. The results showed that over-sizing the electrolyzer with respect to the wind plant minimized curtailment and maximized hydrogen output. While quantifying system cost was outside the scope of this study, an oversized electrolyzer would undoubtedly increase upfront costs. An undersized electrolyzer resulted in more curtailment and less hydrogen produced, but it could guarantee a consistent amount of hydrogen regardless of the wind condition. The simulation also showed a reduction in aerodynamic loads when wind turbines were curtailed, implying less wear-and-tear.
