In a world of energy transition and net zero pledges, low-carbon energy solutions are central in the fight against climate change. Hydrogen plays a key role in a clean energy future, but there are still economic and infrastructural challenges to be overcome. Hydrogen storage in large volumes is one of the value chains current limitations. This paper presents a feasibility study of an offshore blue or green hydrogen storage in salt caverns created by leaching, within potentially identifiable salt deposits extent of the Gulf of Mexico coastline (US). In this case study, the hydrogen station will have caverns to store hydrogen and some caverns to dispose of CO2 from the blue hydrogen (Carbon Capture and Storage – CCS technology). The construction design includes a fixed platform for the H2 HUB and a jack-up platform for drilling. It presents the conceptual design of wells for leaching the caverns and hydrogen injection and withdrawal cycles.
