Geological Hydrogen Storage

Dear Colleagues,

Subsurface hydrogen storage is emerging as a crucial component in the global strategy to harness hydrogen as an energy carrier and industrial feedstock. The ability to store hydrogen in geological formations offers a viable solution to address the inherent challenges of hydrogen production and utilization. By utilizing existing subsurface reservoirs, such as depleted oil and gas fields, aquifers, and salt caverns, we can effectively manage the intermittent nature of energy production, enabling the largest-scale storage that can balance supply and demand across regional economies. This capability not only enhances energy security but also facilitates the integration of hydrogen into existing energy systems, paving the way for a more resilient and flexible energy infrastructure.

Subsurface hydrogen storage presents significant advantages in terms of safety, efficiency, and cost-effectiveness. Geological formations provide a stable environment for long-term storage, minimizing the risks associated with surface storage methods. The potential for high storage capacities allows for the accumulation of hydrogen produced during periods of low demand, which can then be released during peak demand times, thus optimizing the overall energy system. As research and technology in this field advance, understanding the geological, engineering, and economic aspects of subsurface hydrogen storage becomes increasingly important. This Special Issue aims to highlight the latest developments, challenges, and innovations in subsurface hydrogen storage, fostering collaboration and knowledge exchange among researchers, industry stakeholders, and policymakers to accelerate the deployment of subsurface hydrogen storage.

Manuscript Submission Information

Manuscripts should be submitted online at www.mdpi.com by registering and logging in to this website. Once you are registered, click here to go to the submission form. Manuscripts can be submitted until the deadline. All submissions that pass pre-check are peer-reviewed. Accepted papers will be published continuously in the journal (as soon as accepted) and will be listed together on the special issue website. Research articles, review articles as well as short communications are invited. For planned papers, a title and short abstract (about 250 words) can be sent to the Editorial Office for assessment.

Submitted manuscripts should not have been published previously, nor be under consideration for publication elsewhere (except conference proceedings papers). All manuscripts are thoroughly refereed through a single-blind peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions for Authors page. Energies is an international peer-reviewed open access semimonthly journal published by MDPI.

Please visit the Instructions for Authors page before submitting a manuscript. The Article Processing Charge (APC) for publication in this open access journal is 2600 CHF (Swiss Francs). Submitted papers should be well formatted and use good English. Authors may use MDPI's English editing service prior to publication or during author revisions.
