Special Issue Information

Dear Colleagues,

This Special Issue presents high-quality papers selected from the 12th European Conference on Renewable Energy Systems (ECRES2024, ecres.net), which will take place in Riga, Latvia, in hybrid format. This international event is expected to involve participants from more than 60 countries.  

ECRES aims to bring together researchers, engineers and natural scientists from all over the world who are interested in the advancement of all branches of renewable energy systems. Contributions discussing wind, solar, hydrogen, hydro, geothermal, and concentrated solar power; fuel cells; energy harvesting; and other energy-related topics will be included. 

This Special Issue will explore the following related topics:

  • Hydrogen energy system design and implementation;
  • Policies on renewable energy;
  • Energy system optimization;
  • Smart systems;
  • Energy statistics and efficiency;
  • Electric networks;
  • Thermodynamical issues in energy;
  • Wind energy systems;
  • Turbine designs and implementation;
  • Photovoltaic material characterization;
  • Electrical machine design and implementation;
  • Plasma systems for nuclear fusion.

The papers for this Special Issue have already been submitted to the ECRES 2024 conference via the link https://cmt3.research.microsoft.com/ECRES2024 and will be presented at the conference. After approval, successful papers will be directed to the journal.

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 research paper analyzes the use of plasma technology to process biomass in the form of dried, mixed animal manure (dung containing 30% moisture). The irrational use of manure as well as huge quantities of it can negatively impact the environment. In comparison to biomass fermentation, the plasma processing of manure can greatly enhance the production of fuel gas, primarily synthesis gas (CO + H2). The organic part of dung, including the moisture, is represented by carbon, hydrogen, and oxygen with a total concentration of 95.21%, while the mineral part is only 4.79%. A numerical analysis of dung plasma gasification and pyrolysis was conducted using the thermodynamic code TERRA. For 300–3000 K and 0.1 MPa pressure, the dung gasification and pyrolysis were calculated with 100% dung + 25% air and 100% dung + 25% nitrogen, respectively. Calculations were performed to determine the specific energy consumption of the process, the composition of the products of gasification, and the extent of the carbon gasification. At 1500 K, the dung gasification and pyrolysis consumed 1.28 and 1.33 kWh/kg of specific energy, respectively. A direct-current plasma torch with a power rating of 70 kW and a plasma reactor with a dung processing capacity of 50 kg/h were used for the dung processing experiments. The plasma reactor consumed 1.5 and 1.4 kWh/kg when pyrolyzing and gasifying the dung. A maximum temperature of 1887 K was reached in the reactor. The plasma pyrolysis of dung and the plasma–air gasification of dung produced gases with specific heats of combustion of 10,500 and 10,340 kJ/kg, respectively. Calculations and experiments on dung plasma processing showed satisfactory agreement. In this research, exergy analysis was used to quantify the efficiency of the plasma gasification of biomass. One of the research tasks was to develop a methodology and establish standards for the further standardization of monitoring the toxic emissions of dioxins, furans, and Benzo[a]pyrene. Full article
