Green hydrogen is gaining attention as a key contributor to the energy transition, supporting renewable energy storage and the decarbonization of industries such as steel production. Designing efficient hydrogen systems is challenging due to fluctuating renewable energy inputs, storage limitations, and efficiency requirements. The blog describes how Dymola, within the CATIA Systems portfolio, together with dedicated Modelica libraries, supports simulation, optimization, and validation of hydrogen systems before physical deployment.
The Hydrogen Library aims to simplify the modeling of electrolyzers, methane reformers, storage tanks, and fuel cells while supporting the evaluation of operating strategies. Web-based tools such as Systems Simulation Designer and Systems Simulation Analyst aim to make simulation accessible without requiring extensive software expertise, while the Process Modeling and Engineering Library supports the simulation of hydrogen purification processes, together enabling more informed hydrogen system development.
