The advancement of hydrogen-related technologies and the hydrogen economy must be built on a foundation of reliable assessments of their economic feasibility, environmental impacts, and efficiency. These assessments determine whether a system is competitive with established references. Consequently, they need to be performed for novel hydrogen production, transport, storage, and utilization technologies. Further, integrating these aspects into an overall energy system model is necessary for building confidence and a positive public perception. The CSA deals with the assessments of hydrogen-based technologies and systems at different scales of application addressing socio-economic, techno-economic, and environmental criteria, under the following sub-topics:

1. Design of sustainable socio-economic hydrogen energy systems
2. Life-cycle analyses and ecosystems research
