Accelerating the Adoption of Low-Temperature Electrolysis for Hydrogen Production

Dear Colleagues,

Increasing amounts of low-cost low-carbon electricity are enabling new opportunities to shift electricity to other products to decarbonize hard-to-electrify industrial and transportation sectors of our economy. By whatever name you like to use (and there are many) – Power-to-Gas, Electrons-to-Molecules, Power-to-X, Hydrogen Production, Water Electrolysis – all of them involve transforming electricity to energy stored in molecular bonds. One uniting characteristic is the idea that this approach possesses the ability to scale to levels that will enable meaningful near-term decarbonization. With this in mind, the non-binding guidance below contains this theme of scaling to GW-levels to help reduce costs, impact markets and reduce the carbon intensity of the products. The topics focus on system-level scaling and manufacturing, and intentionally removes focus from the ever-important, but often researched, cell- and stack-level challenges. 

Topics for this Special Issue include, but are not be limited to, the following research, development and demonstration (RD&D) areas of low-temperature water electrolyzer systems:

• System scaling (10MW – 1 GW) to reduce capital cost
• Manufacturing initiatives to reduce capital cost
• Close- and direct-coupling of renewable electricity sources to the hydrogen-producing electrolyzer stack
• Challenges and opportunities to reduce rectifier (AC/DC) power conversion costs
• It’s Starting: Operational case studies that are already decarbonizing an industrial process or producing drop-in direct replacements for fossil fuels
• An Eye to the Future: Emerging technologies, like alkaline exchange membrane-based systems, that show promise in reducing costs.

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. Batteries is an international peer-reviewed open access monthly 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 2700 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.
