Advances in CO₂-Free Energy Technologies

Dear Colleagues,

Because of the rapid depletion of conventional energy sources, increasing energy demand, and related environmental issues, the biggest challenge in today’s world is to meet the growing energy demands in an environmentally benign and sustainable manner. Innovation in CO₂-free energy technologies is essential for the establishment of a prosperous, low-carbon economy and sustainable society. To achieve the rapid deployment of renewables-based CO₂-free energy technologies, it is urgently required to develop efficient and sustainable technologies that can be applied to achieve the same economic scale that has been achieved in established processes. Currently, renewables-based CO₂-free clean energy technologies are being deployed widely, and include solar, thermal, wind, hydro, biomass, and geothermal energies, the utilization of CO₂-free green fuels (including hydrogen, ammonia, and biofuels), storage technologies, etc. The development of efficient and cost-effective CO₂-free clean energy technologies will encourage the replacement of conventional fossil-fuel-based energy systems, which is ultimately required for the development of a sustainable society. The purpose of this Special Issue of Energies is to bring together ideas, solutions, and challenges for the implementation of CO₂-free green energy technologies in the form of research articles and review papers. Topics of interest for publication include, but are not limited to:

1. Solar, wind, geothermal, and bioenergy, and their applications;
2. Energy conversion and storage;
3. Materials and devices for energy storage (e.g., batteries and supercapacitors);
4. Catalysts, electrocatalysts, and photocatalysts;
5. Hydrogen production and storage;
6. Ammonia synthesis and its combustion as a source of energy;
7. Clean fuel and fuel cell applications.

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-anonymized 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.
