Design of the Renew2H2 Wind to Hydrogen Model and Initial Case Study

As the global transition towards net-zero emissions accelerates, there is increasing demand for green hydrogen. Wind energy, being the predominant renewable energy source in northern Europe, presents an attractive option to pair with electrolysis for hydrogen production. This paper introduces the Renew2H2 model, a simulation tool designed to evaluate wind-to-hydrogen systems. The model incorporates detailed sub-models for wind power input, electrolyser operation, battery operation and control, enabling the simulation of multi-year operations and the assessment of hydrogen production, electrolyser degradation, and battery degradation. The modular design of Renew2H2 ensures ease of future expansion and updates. An initial case study demonstrates the model’s utility, highlighting the impact of power smoothing on electrolyser degradation and the trade-offs between battery and electrolyser lifetimes.
