Work Package 3: Assessment of geologic options for hydrogen underground storage

WP3's main objective is to compile and present all known physical options of underground high pressure gas storage, their characteristics and a ranking of the applied technologies, their applicability as well as their potential for use as hydrogen storage. Work package participants will first present all existing options, such as aquifers, rock caverns, depleted gas and oil fields and salt caverns. Once all options are evaluated, a list of relevant criteria and plant safety assessment o will be prepared for the different storage options. Through this process existing hydrogen underground storage plants will be evaluated worldwide. The final result ofWP3 will be a recommendation for the most suitable hydrogen underground storage option(s), based on which WP6 will be carried out.

This work package is led by KBB from Germany.
