Special Issue Information

Dear Colleagues,

We are excited to announce a new Special Issue of Applied Sciences, titled "The Present and the Future of Hydrogen Energy". This Special Issue aims to bring together pioneering research and advancements in the field of hydrogen energy, which is rapidly emerging as a cornerstone for sustainable and clean energy solutions worldwide.

Hydrogen energy holds the promise of revolutionizing various sectors, from transportation and power generation to industrial applications. This Special Issue will explore the latest technological developments, innovative applications, and strategic policies driving the hydrogen economy forward. We invite researchers to submit their original papers, reviews, and case studies that delve into topics such as hydrogen production, storage, distribution, and utilization. Additionally, papers addressing the challenges and opportunities in scaling up hydrogen technologies, economic feasibility, safety, and environmental impacts are highly encouraged.

Join us in contributing to this vital discourse on hydrogen energy and help shape a sustainable future.

We look forward to receiving your valuable submissions and insights that will expand the horizons of hydrogen energy possibilities.

Dr. Daniele Melideo
Guest Editor

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 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. Applied Sciences 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.

Hydrogen produced from renewable sources has the potential to tackle various energy challenges, from allowing cost-effective transportation of renewable energy from production to consumption regions to decarbonizing intensive energy consumption industries. Due to its application versatility and non-greenhouse gaseous emissions characteristics, it is expected that hydrogen will play an important role in the decarbonization strategies set out for 2050. Currently, there are some barriers and challenges that need to be addressed to fully take advantage of the opportunities associated with hydrogen. The present work aims to characterize the state of the art of different hydrogen production, storage, transport, and distribution technologies, which compose the hydrogen value chain. Based on the information collected it was possible to conclude the following: (i) Electrolysis is the frontrunner to produce green hydrogen at a large scale (efficiency up to 80%) since some of the production technologies under this category have already achieved a commercially available state; (ii) in the storage phase, various technologies may be suitable based on specific conditions and purposes. Technologies of the physical-based type are the ones mostly used in real applications; (iii) transportation and distribution options should be viewed as complementary rather than competitive, as the most suitable option varies based on transportation distance and hydrogen quantity; and (iv) a single value chain configuration cannot be universally applied. Therefore, each case requires a comprehensive analysis of the entire value chain. Methodologies, like life cycle assessment, should be utilized to support the decision-making process. Full article
