H2RES is an open-source energy systems model designed to support the analysis of integrated and sector-coupled energy transitions. It brings together planning, system operation, and scenario comparison within a flexible framework intended for research, teaching, and applied energy studies.
Select the right model version for your work and set it up.
For long-term planning and scenario comparison across electricity, heat, hydrogen, and transport systems.
For reproducible studies on sector coupling, system flexibility, and low-carbon transition pathways.
For structured learning paths, workshops, summer schools, and introductory exercises in energy systems modelling.
H2RES is an open-source energy systems model used to explore integrated transition pathways through a combination of planning, system operation, storage, and cross-sector interactions.
H2RES has existed for more than two decades and holds an important place in energy systems modelling as the first model used in a peer-reviewed study of a 100% renewable energy system. Since then, it has evolved from early renewable energy case studies into a broader framework for integrated energy systems analysis.
H2RES is developed through collaboration among universities and research partners working on open and transferable approaches to energy systems modelling.
H2RES follows an open development approach and is distributed under an open-source license to support transparent and reusable research workflows.
Learn how to install H2RES, run simulations and interpret results.
Learning resources for users moving from installation and baseline execution toward structured scenario development.
Set up H2RES, execute a first baseline case, and verify that the expected outputs are produced correctly.
Create a scenario by modifying demand trajectories, technology assumptions, and policy constraints.
Compare scenarios using planning assumptions, cost indicators, and system-level outcome metrics.
Peer-reviewed articles, in-proceedings papers, technical reports, theses, project deliverables, and curated databases developed with H2RES.
