Special Issue Information

Dear Colleagues,

Renewable energy technologies play a significant role in meeting the global energy demand in an environmentally friendly and sustainable way. The use of renewable energy technologies to provide electricity, heating and cooling, and transportation have increased significantly throughout the world. Although there is a growing demand for cost-effective renewable energy technologies, their potential varies with respect to available resources, climate, geographical location and storage possibilities. At present the key challenges related to the renewable energy technologies are high capital costs, underdeveloped technologies, and improvements in efficiency and energy saving potential on the demand side. Renewable energy technologies can be classified into two categories: emerging energy technology and mainstream energy technology. Mainstream energy technologies are well-established, whereas emerging technologies are still under development.

The increased integration of renewable energy systems into the electricity grid also creates new challenges due to their intermittent generation throughout the year. Energy storage systems are able to mitigate this problem by improving the performance of the power grid, balancing supply and demand and improving power quality and reliability. Thus, in the future, the advancement of storage technology will play a key role in the successful deployment of renewable energy technologies in the electricity grid.

The aim of this Special Issue is to capture recent breakthrough research contributions related to advanced emerging renewable technologies including new concepts and innovative approaches, challenges, design and development, system configurations and sizing, theoretical and experimental investigations, techno-economic analysis and environmental impact analysis .

Topics of interest for this Special Issue include but are not limited to the following:

  • New trends and technologies
  • Solar photovoltaic technologies
  • Solar thermal systems
  • Concentrating solar technologies
  • Nanotechnology and solar power
  • Wind energy
  • Bio-energy
  • Wave, tidal, ocean energy
  • Heat pump
  • Energy storage technologies
  • Artificial intelligence studies in renewable energy systems
  • Energy management
  • Techno-economic analysis of renewable energy systems
  • Environmental impact analysis
  • Modelling of energy systems
  • Integration of renewable energy technologies into the grid
  • Review of technologies
  • Application of technologies and assessments
  • Distributed energy systems
  • Control techniques for renewable energy systems

Solar energy has shown to be a successful renewable source, wherefore large investments are planned in the upcoming decades. This work aims at developing technical and economical solutions to optimize a utility-scale grid connected solar photovoltaic park with an installed capacity of 24 MWp. Several successive simulations were automatically performed with the PVSyst software, so that each influencing parameter is individually analyzed. Moreover, a comprehensive study touching relevant aspects, such as central versus string inverters, landscape versus portrait dispositions, the optimal tilt angle (for fixed tilt systems), backtracking strategy (for single axis tracking systems), shading limit angle, and pitch is performed with the objective of finding the configuration leading to the higher grid injected energy output. The levelized cost of energy (LCOE) was obtained for 12 different cases in which, for both fixed tilt and single-axis tracking (SAT), central and string inverters and portrait/landscape disposition were considered. The lowest LCOE achieved was 32.23 €/MWh, which is a clear indication of the competitiveness of the solar Photovoltaic (PV) technology. The most economic viable solution is characterized by the employment of an SAT system with the backtracking strategy, together with string inverters and module portrait disposition. Full article

Lithium-ion batteries are currently used for various applications since they are lightweight, stable, and flexible. With the increased demand for portable electronics and electric vehicles, it has become necessary to develop newer, smaller, and lighter batteries with increased cycle life, high energy density, and overall better battery performance. Since the sources of lithium are limited and also because of the high cost of the metal, it is necessary to find alternatives. Sodium batteries have shown great potential, and hence several researchers are working on improving the battery performance of the various sodium batteries. This paper is a brief review of the current research in sodium-sulfur and sodium-air batteries. Full article
