TY - CONF A1 - Maiwald, Michael A1 - Lubenau, U. T1 - Large-scale hydrogen storage in geological reservoirs: Current perspectives and requirements for metrology N2 - The course of the changeover of UGS from natural gas to hydrogen varies depending on the type of the underground gas storage (UGS). In caverns a changeover to high H2-contents can be achieved quickly, while pore storage tanks must be converted over long periods of time. The analytical requirements are correspondingly different. This information has been compiled through expert statement by underground storage operators. A significant number of new UGS is currently not expected. Public funds (project funding) are currently being raised for the conversion of caverns to hydrogen. In addition, investigations and evaluations of the material are currently being carried out at various storage facilities in order to determine the possibilities and costs of a conversion. H2 admixtures to natural gas, but also pure H2 caverns are considered. The bottleneck seems to be the availability of large volumes of hydrogen. The analytical requirements along with the different hydrogen qualities, which are currently discussed were compiled through expert discussions with underground storage operators and are at hand as early impact results.
