Abstract

This paper describes the system modeling tools and evaluation methods developed in International Energy Agency (IEA) Hydrogen Implementing Agreement (HIA) on Integrated Systems (Annex 18). The general method used is to gather data and evaluate stationary hydrogen energy demonstration projects, verify the models and assumptions used in the modeling tools, and/or to investigate alternative designs. The specific focus presented here is the technical evaluations and simulation models developed for two actual installations: (1) an electrolyzer-based hydrogen refueling station in Reykjavik, Iceland and (2) an integrated electrolyzer/metal hydride/fuel cell system in Takasago, Japan. Comparisons between data and models show that the hydrogen system simulators developed are suitable to evaluate systems with respect to design and operation (e.g. energy efficiency and system availability), but more exact data on hydrogen compressor work is required. Alternative hydrogen compression and storage systems for refueling stations are also proposed. Detailed analyses show how important it is to properly understand the heat exchange mechanisms and characteristics (kinetics) of metal hydrides before designing fully integrated metal hydride systems. Recommendations for future work on how to apply the tools available on similar hydrogen energy systems and refueling stations are provided.
