Today, about 95% of man-made hydrogen comes from steam-reforming, a technology, which is efficient, but comes with a large carbon footprint.
To reach the global climate goals, two things, besides others, must happen: At first, different technologies to produce hydrogen need to be used. Secondly, more and more CO2 intensive industrial processes need to be converted to use hydrogen instead of fossil fuels. This means, in the decades to come, much more hydrogen will be needed, and it will be produced differently and at different places. If hydrogen is produced by electrolysis from renewable electricity sources like solar and wind, then this electricity sources are not steady and not necessarily available when hydrogen demand is high. So, hydrogen need to be produced in advance and stored to guarantee constant supply.
Hydrogen molecules, however, are smaller and more reactive compared to natural gas or oil. So, the technical and geological requirements for a hydrogen storage differ from hydrocarbon or CO2 storages.
At NiMBUC Geoscience, we are involved in modelling of storages for hydrogen. We model the geomechanical conditions of the rocks to ensure, that hydrogen storages can be operated safely and economically. The results of such mathematical models allow our clients to test their chosen formations and to find the right spots for contructing well performing hydrogen storages.
