Special Issue Information

Dear Colleagues,

As a typical sustainable energy carrier, hydrogen energy has great potential for future development. It can be widely used in hydrogen energy vehicles, power generation, aerospace, and other fields. However, due to its attractive properties, such as high diffusivity, low ignition energy, and wide explosion range, hydrogen has a high risk of leakage and explosion in production, storage, and use. This Special Issue hopes to attract experts from all over the world and provide an open platform for the presentation and discussion of new findings, information, and data on hydrogen safety, from basic research to applied development and from good practice to standardization and regulatory issues.

In this Special Issue, original research articles and reviews are welcome. Research areas may include (but are not limited to) the following:

  1. Release and dispersion of gaseous and liquid hydrogen;
  2. Physical (e.g., thermal/overpressure) effects on surroundings and consequence analysis;
  3. Hydrogen fire and explosion dynamics;
  4. Safety technologies for preventing and mitigating hydrogen fires and explosions;
  5. Hydrogen effects on materials and components;
  6. Safety of hydrogen fueling stations;
  7. Risk analysis and safety management of hydrogen systems;
  8. Emergency management/response technology and applications;
  9. Safety in hydrogen infrastructure;
  10. Safety in hydrogen transportation;
  11. Safety in hydrogen vehicles;
  12. Safety in hydrogen-based energy storage systems;
  13. Hydrogen safety in other practices and industries;
  14. Hydrogen codes and standards;
  15. Hydrogen and sustainable energy.

We look forward to receiving your contributions.

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. Sustainability 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 2400 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.

The carbon emission reduction mission requires a multifaceted approach, in which green hydrogen is expected to play a key role. The accelerated adoption of green hydrogen technologies is vital to this journey towards carbon neutrality by 2050. However, the energy transition involving green hydrogen requires a data-driven approach to ensure that the benefits are realised. The introduction of testing sites for green hydrogen technologies will be crucial in enabling the performance testing of various components within the green hydrogen value chain. This study involves an areal assessment of a selected test site for the installation of a grid-tied solar PV-green hydrogen-battery storage microgrid system at a factory facility in South Africa. The evaluation includes a site energy audit to determine the consumption profile and an analysis of the location’s weather pattern to assess its impact on the envisaged microgrid. Lastly, a design of the microgrid is conceptualised. A 39 kW photovoltaic system powers the microgrid, which comprises a 22 kWh battery storage system, 10 kW of electrolyser capacity, an 8 kW fuel cell, and an 800 L hydrogen storage capacity between 30 and 40 bars.
