Risks and impacts of microbial processes on underground hydrogen storage performance

Hydrogen is expected to be a key component of the Netherlands' future energy matrix. Underground hydrogen storage (UHS) in porous reservoirs and salt caverns is being explored to meet the anticipated storage needs. However, the involvement of hydrogen in microbiological and biogeochemical processes raises concerns about potential long-term underground storage losses. This project aims to evaluate the risks and impacts of microbial activity on UHS. Ultimately, these findings will contribute towards safely developing UHS infrastructure in the Dutch territory, supporting the nation's COP 21 commitments to transition to a net zero-carbon energy system by 2050.
