Special Issue Information

Dear Colleagues,

We are in the midst of a global systemic shift away from fossil fuel use towards alternative power sources in every sector. While it is widely agreed that there is no perfect solution (i.e., a silver bullet), a few options do exhibit the technology readiness, magnitude of production, potential for multi-sector application, and scope for future improvements required to address this challenge. Ammonia (NH3) is one such option.

c.180Mt p.a. is consistently one of the most produced chemicals today. While it is currently predominantly used for fertiliser, its production supports roughly half of the global population and accounts for 1.3% of global fossil fuel consumption. While the decarbonisation of ammonia production is important in its own right, once decarbonised, using either mature or novel technology, it has many other potential uses, such as shipping and aviation fuel, as an energy vector, and for energy storage. Only careful and creative considerations across the value chain will enable green ammonia to be deployed successfully and dependably at the scale and rate required.

Both technical and economic improvements in key production processes, such as hydrogen production and ammonia synthesis, could be game-changing. However, safety is of paramount importance. Whilst ammonia has been globally handled for over a century, implementing different production methods, storage requirements, and uses in new sectors requires careful consideration and regulation. With greater demand and new applications, consideration of the logistics is key to its successful deployment quickly and at scale. While there have been notable developments in this area, both academically and commercially, the conversion of ammonia to a source of power remains a key field of interest given its importance for many uses. Alongside this is the need to better understand the future demand for green ammonia as an energy vector / long-term energy storage solution. Techno-economic analysis along the value chain remains important to inform stakeholders, from those working on fundamental research to system planners/policymakers.

This Special Issue aims to present recent progress on the production, logistics, and/or use of ammonia as a fuel for carbon-free energy, which could contribute to an improved understanding of its impact on the energy sector. Original research articles and comprehensive reviews along with well-documented case studies will be considered for publication.

The following topics will be addressed:

  • Novel methods of ammonia production using renewable energy sources;
  • Developments of ammonia and/or hydrogen production;
  • Safety, regulation, and/or public acceptance of using ammonia as an energy source;
  • Logistical considerations from production to use;
  • Conversion of ammonia to power;
  • Requirement of an alternative energy vector/long-term energy storage option such as ammonia;
  • Market and techno-economic analysis of any aspect(s) of this value chain;
  • Investigation of sector coupling and its opportunities and challenges;
  • Report on case studies of any aspect(s) of this value chain;
  • Environmental studies of any aspect(s) of this value chain.

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. 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.
