Hydrogen storage in porous media: Pre- and post- batch experiment assessment of borehole samples Report

In response to this need, the British Geological Survey (BGS) has recently completed a collaboration with the University of Manchester to investigate the behaviour of hydrogen in the laboratory using samples of porous rocks that may be considered for future storage. [...] Structurally, the basin is fault bounded to the east and south-east and is partially separated from the East Irish Sea Basin to the north-east by the Llŷn–Rossendale ridge. [...] The Hythe Formation is the second oldest of the Lower Greensand in the Wealden Basin, and is Early to Late Aptian in age. [...] The Sandgate Formation is interpreted as being deposited in a shallow marine environment (similar to the Hythe Formation), and this is clearly evidenced by the glauconite and fossiliferous/bioturbated nature of the sediments. [...] The overlying unit, the Glauconitic Marl Member (basal member of the West Melbury Chalk Formation), rests disconformably, and 12 marks the passage into the Upper Cretaceous in the Cenomanian.
