Hydrogen storage is a critical component for enabling flexibility in the energy system, balancing supply and demand, and supporting seasonal and long-term energy storage. This sub-workshop explores a wide range of hydrogen storage solutions, including physical storage (compressed and liquid), solid-state storage (metal hydrides and chemical hydrides), and chemical carriers such as ammonia and liquid organic hydrogen carriers (LOHCs).

The workshop addresses performance, safety, scalability, and cost considerations, providing participants with a holistic understanding of storage options and their integration into hydrogen supply chains. Academic presentations will focus on storage materials, reaction kinetics, and system modelling, while industry speakers will share lessons from large-scale implementation, safety management, and infrastructure deployment.

The workshop aims to provide actionable guidance for technology selection, operational planning, and investment in hydrogen storage, supporting both energy and industrial applications.
