Underground Hydrogen Storage - Technology Monitor Report 2023

In 2022 the Hydrogen Technology Collaboration Program approved to start up a new international task, known as TCP-Task 42, on storage of hydrogen in underground geological formations (UHS). Currently 54 participants from industry, universities, research organizations and governmental background have joined forces to seek synergies and opportunities for researching the main technical and economic challenges of UHS, which will help to advance towards demonstration in a full operational environment and to establish expertise and guidelines for all stakeholders involved.

Over the past 5 years there has been a strong increase in research projects and studies investigating the feasibility and operational conditions of UHS in different subsurface settings. There is a wealth of new information and insights which now need to be demonstrated in a real environment. In this first TCP-Task 42 report we have compiled these insights based on the expertise and experiences of all participating experts involved. From this overview we have formulated several key actions and recommendations which will pave the way for a safe and responsible implementation in the coming years. Click here for the full report.
