Special Issue Information

Dear Colleagues,

Fossil fuels have been used as major energy sources in power generation, transportation, and industrial sectors because of their abundance and inexpensive price. However, critical issues related to a harmful effect on human health and the environment by their utilization cannot be overlooked have risen. There has also been tremendous pressure on fields of energy systems using fossil fuels to restrict pollutant emissions (CO2, NOx, and SO2), because these gas emissions in the atmosphere increase energy consumption in the world. Accordingly, reduction technology for gas emissions has been firmly established from fundamental to advanced research on industrial energy systems in the last several decades.

This Special Issue of Energies focuses on recent advances in reduction technologies of gas emissions in combustion-related applications. Topics of interest include, but are not limited to the following:

  • Emission control technologies by experimental and numerical approaches;
  • Emission control technologies in pre-combustion, in-furnace combustion, and post-combustion;
  • Emission control technologies in power generation, transportation, and industrial process;
  • New process and equipment development for efficient gas emission reduction;
  • Utilization in various fossil fuels (coal, natural gas, biomass, and their blends);
  • Optimization for emission control with machine learning applications in energy systems.

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.

This study addresses the challenges of and opportunities for achieving the ambitious greenhouse gas emissions reduction target of the fishery sector of the Republic of Korea, set at 96% by 2030. We also focus on the current status of land-based aquaculture and underground seawater resource development, quantitatively compare energy inputs for land-based fish cultivation, and evaluate the potential of underground seawater to reduce CO2 emissions. Since 2010, 762 underground seawater boreholes have been developed, yielding a cumulative daily pumpage of 125,780 m3. Jeollanam-do was found to have the highest daily pumpage, with an annual energy requirement of 131,205,613 Mcal. Despite the fact that the energy demands for underground seawater are higher in some months, it provides a 22.6% reduction in total annual energy consumption compared to surface water. The use of underground seawater for heating or cooling resulted in a 24.1% reduction in the required input energy. However, energy requirements increase due to the relatively high surface water temperature in some regions and seasons. This study also highlights the utilization of underground seawater in heating or cooling surface water via indirect applications using geothermal heat pumps. This innovative research broadens the methods of greenhouse gas mitigation, particularly in the agriculture, livestock, and fisheries industries. Full article
