ADX Energy Ltd. (ASX: ADX, FSE: GHU) is an Australian- and German-listed company that has had two producing oil fields, Gaiselberg and Zistersfeld, in Lower Austria since late 2019. The fields have a life of around ten years, which ADX hopes to extend to 20 years through extensions and new drilling. Currently, production is around 430 barrels per day and the extracted oil and gas is delivered directly through a pipeline to the Schwechat refinery for further processing. The classic oil and gas production is rounded off by new green business fields, such as the production of green hydrogen and the use of the large-volume former oil fields as hydrogen storage facilities.
