PRISMAS/Hydrotrans – migration of geologically stored hydrogen in bedrock

Hydrogen (H2) is key to the electrification of industrial processes and implementation requires large-scale H2 storage.

The lined rock cavern technique (LRC) is tested for storage of H2, but there may be more cost-effective storage alternatives for the industry. Geological reservoirs unconventional for H2 storage are promisingly being investigated abroad and Sweden has similar but older bedrock, so far untested for H2 storage. The novelty in the project is to investigate how H2 in detail migrates through geological rock types common around major industry sites in northern Sweden, which today is poorly known. Results inform H2 storage site selection in a national/international industry perspective. Actively supported by relevant industry partners, we use microanalytical characterization and advanced fluid/gas dynamics modelling flow to address the feasibility of large-scale geological storage of H2 connected to the industrial transition into renewable energy sources.

Participating research groups at LTU are experimental mechanics (project leader), ore geology, and fluid mechanics, together with MAX IV, and industry partners are Vattenfall-HYBRIT, H2 Green Steel, Svensk Kärnbränslehantering AB (SKB). The project is funded by EU MSCA COFUND.
