Recently, Nobian completed the first of two exploratory drillings for the HyStock Waterstofopslag hydrogen storage project in Zuidwending, the Netherlands. The well was drilled to a depth of approximately 1,500 metres into the Zechstein salt diapir located in the subsurface beneath Zuidwending. The so-called A9 well featured extensive geological logging and sampling, including continuous coring of the 350-metre cavern depth interval. This operation was safely executed by IOT Holland, working closely with the GEOKRAK sp. z o.o. wellsite geologist, who ensured the core was carefully handled, photographed and documented (the image below shows several salt samples). The drilling rig is now being moved to the nearby A11 location, where the second exploratory well will soon be drilled. Both wells are part of the HyStock project by EnergyStock BV, a subsidiary of Gasunie. These exploratory drillings represent an important step towards enabling safe, large‑scale underground hydrogen storage in the Netherlands. The data collected will help determine how future salt caverns can be designed and mined safely and reliably for hydrogen storage. The development of underground hydrogen storage in caverns requires prior salt extraction. Underground hydrogen storage is essential for the energy transition. It will play a key role in balancing supply and demand in a future national hydrogen network. #energystorage #hydrogenstorage #saltmining #salt #GrowGreenerTogether
