Special Issue Information

Dear Colleagues,

Today, probably everyone has heard about hydrogen, which is anticipated to become one of the most important energy carriers in the near future. Hydrogen can be used in a fuel (hydrogen) cell—a device that converts chemical energy from fuel (hydrogen) into electricity by chemically reacting with oxygen or another oxidizing agent. Such a fuel cell can run practically without interruption as long as hydrogen is supplied, emitting only heat and water vapor. While oxygen can come directly from the atmosphere, the problem is the efficient, green, and cheap production and storage of hydrogen.

Although we have a lot of hydrogen on Earth, it exists in a bound form. This means that energy is needed to extract it—hydrogen is a carrier, not an energy source. This means that a primary source of energy is used to produce hydrogen, such as fossil fuels, natural gas, nuclear energy, solar energy, biomass, wind, water, and geothermal energy.

Another problem is hydrogen storage. Currently, hydrogen is stored mainly by physical means—under high pressure and in liquid form. Nevertheless, hydrogen storage technologies using adsorption and chemisorption have brought many interesting solutions and have been the subject of extensive scientific research. The aim of this Special Issue is to synthetically compile the latest information on hydrogen production and storage. The topics of interest for the publication include  all aspects related to:

  • Hydrogen production methods:
    • Conventional production methods (natural gas reforming, coal gasification);
    • Renewable hydrogen production methods (solar energy, wind energy, geothermal energy, hydro energy, biomass gasification, etc.);
    • Other nonconventional production methods (nuclear-based hydrogen production, ammonia cracking, aluminum-based hydrogen production, biological hydrogen production, etc.);
    • Thermochemical cycles.
  • Hydrogen storage:
    • Compressed gas
    • Cold/cryo-compressed gas
    • Liquid H2, slush hydrogen
    • Metal hydrides (MH)
    • Adsorbent
    • Liquid organics
    • Complex hydride
    • Chemical hydrogen
    • Construction of tanks and systems for hydrogen storage

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 100 words) can be sent to the Editorial Office for announcement on this website.

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.

The gasification of Polish coal to produce hydrogen could help to make the country independent of oil and gas imports and assist in the rational energy transition from gray to green hydrogen. When taking strategic economic or legislative decisions, one should be guided not only by the level of CO2 emissions from the production process, but also by other environmental impact factors obtained from comprehensive environmental analyses. This paper presents an analysis of the life cycle of hydrogen by coal gasification and its application in a vehicle powered by FCEV cells. All the main stages of hydrogen fuel production by Shell technology, as well as hydrogen compression and transport to the distribution point, are included in the analyses. In total, two fuel production scenarios were considered: with and without sequestration of the carbon dioxide captured in the process. Life cycle analysis was performed according to the procedures and assumptions proposed in the FC-Hy Guide, Guidance Document for performing LCAs on Fuel Cells and H₂ Technologies by the CML baseline method. By applying the CO2 sequestration operation, the GHG emissions rate for the assumed functional unit can be reduced by approximately 44% from 34.8 kg CO2-eq to 19.5 kg CO2-eq, but this involves a concomitant increase in the acidification rate from 3.64·10−2 kg SO2-eq to 3.78·10−2 kg SO2-eq, in the eutrophication index from 5.18·10−2 kg PO3−4-eq to 5.57·10−2 kg PO3−4-eq and in the abiotic depletion index from 405 MJ to 414 MJ and from 1.54·10−5 kg Sbeq to 1.61·10−5 kg Sbeq.

Laves phases crystallize in simple structures and are very common intermetallic phases that can form from combinations of elements throughout the periodic table, giving a huge number of known examples. A special feature of AB2 or AB5 phases is the ability to absorb hydrogen. This study attempts to collect, systematize and summarize the knowledge about RMn2Hx (R: Tb, Gd, Ho, Dy, Er, Sm, Nd and Y) hydrides available in the literature that is mainly related to structural and magnetic transformations. Due to the enormous wealth of data, the analysis focused on hydrides with x < 4.5 H/f.u., i.e., hydrides obtained at relatively low pressure (less than a few bars). The hydrides obtained in this way can be treated as potential hydrogen stores, which undoubtedly accounts for their current attractiveness. Full article
