Topic Information

Dear Colleagues,

Energy is the vital gear of global energy and life sustainability. The development of renewable energy derivatives, the key concept of biorefinery, is an essential feature of modern economies focusing on the decarbonization of production practices. As such, renewable energy is a highly prioritized research sphere with the prime focus of investment in the current era. Following the successful development of biofuel technologies, the development of high-energy biomolecules and bio-derivatives with extended applications has been a key focus. In addition, progress in energy technologies has emerged with the development of organic materials as sustainable, biodegradable, and readily available materials for energy supply and energy storage, replacing their fossil and inorganic counterparts. In line with all of these developments, research and innovation in these fields are expanding at a rapid rate, and we, as members of the journal Energies, are committed to facilitating the communication of high-quality studies in this field. This topic focuses on the latest fundamentals and applied innovations, both experimental and computational, in the field of renewable energy and energy derivatives, covering the synthesis, purification, kinetics, and applications in various fields. The topic includes, but is not limited to, the following:

  • Production of biofuels, syngas, and biohydrogen;
  • Production of biochemicals, biomaterials, and bioderivatives;
  • Production and applications of biopolymers and bioplastics;
  • Separation and purification of biofuels, biochemicals, biomaterials, and polymers;
  • Novel energy storage solutions; Integrated renewable energy systems;
  • Energy systems modeling and optimization (including numerical and analytical modeling, computational chemistry, etc.);
  • Energy system components and design;
  • Renewable energy and energy economy;
  • Life cycle assessment for related systems;
  • Energy safety.

The development of alternative energies has become a concern for all countries to ensure domestic energy supply and provide environmental friendliness. One of the providential alternative energies is biodiesel. Biodiesel, commonly stated as fatty acid alkyl ester (FAAE), is a liquid fuel intended to substitute petroleum diesel. Nevertheless, implementation of pure biodiesel is not recommended for conventional diesel engines. It holds poor values of cold flow properties, as the effect of high saturated FAAE content contributes to this constraint. Several processes have been proposed to enhance cold flow properties of biodiesel, but this work focuses on the skeletal isomerization process. This process rearranges the skeletal carbon chain of straight-chain FAAE into branched isomeric products to lower the melting point, related to the good cold flow behavior. This method specifically requires an acid catalyst to elevate the isomerization reaction rate. And then, sulfated tin(IV) oxide emerged as a solid superacid catalyst due to its superiority in acidity. The results of biodiesel isomerization over this catalyst and its modification with iron had not satisfied the expectation of high isomerization yield and significant CFP improvement. However, they emphasized that the skeletal isomers demonstrated minimum impact on biodiesel oxidation stability. They also affirmed the role of an acid catalyst in the reaction mechanism in terms of protonation, isomerization, and deprotonation. Furthermore, the metal promotion was theoretically necessary to boost the catalytic activity of this material. It initiated the dehydrogenation of linear hydrocarbon before protonation and terminated the isomerization by hydrogenating the branched carbon chain after deprotonation. Finally, the overall findings indicated promising prospects for further enhancement of catalyst performance and reusability. Full article

This study evaluates the techno-economic feasibility of solar-based green hydrogen potential for off-grid and utility-scale systems in Niger. The geospatial approach is first employed to identify the area available for green hydrogen production based on environmental and socio-technical constraints. Second, we evaluate the potential of green hydrogen production using a geographic information system (GIS) tool, followed by an economic analysis of the levelized cost of hydrogen (LCOH) for alkaline and proton exchange membrane (PEM) water electrolyzers using fresh and desalinated water. The results show that the electricity generation potential is 311,617 TWh/year and 353,166 TWh/year for off-grid and utility-scale systems. The hydrogen potential using PEM (alkaline) water electrolyzers is calculated to be 5932 Mt/year and 6723 Mt/year (5694 Mt/year and 6454 Mt/year) for off-grid and utility-scale systems, respectively. The LCOH production potential decreases for PEM and alkaline water electrolyzers by 2030, ranging between 4.72–5.99 EUR/kgH2 and 5.05–6.37 EUR/kgH2 for off-grid and 4.09–5.21 EUR/kgH2 and 4.22–5.4 EUR/kgH2 for utility-scale systems.
