Special Issue Information

Dear Colleagues,

This Special Issue, “Recent Advances in Renewable Energy Systems Toward Sustainable Development”, aims to collect high-impact articles that focus on innovative research and emerging technologies that can assist the global transition toward clean and sustainable energy systems. It captures all related technologies—such as solar, wind, geothermal, biomass, hydropower, and combinations of hybrid systems—along with breakthrough system integrations, including energy storage, autonomous operation, energy management, and minimal environmental impact.

We welcome contributions that explore and apply sustainable design, zero environmental impact, and novel integration strategies in zero-carbon infrastructure alongside energy security. By addressing technical, economic, and policy challenges, this Special Issue offers valuable insights for accelerating renewable energy adoption, fostering resilience, and promoting sustainable development aligned with global climate and energy goals at both local and international levels.

Topics of interest include, but are not limited to, the following:

  • Renewable energy systems and energy storage;
  • Emerging clean technologies in sustainable development;
  • Environmental impacts (LCA, LCC);
  • Smart grids and integrated energy systems;
  • Hydrogen energy, fuel cells, and water electrolyzers;
  • Energy efficiency and optimization;
  • Green policies and energy transition;
  • Energy management, control systems, and optimization.

The increasing integration of renewable energy sources, such as solar photovoltaics, requires low-cost, scalable energy storage solutions suitable for decentralized systems. This work experimentally evaluates an iron chloride concentration redox flow battery (FeCl-CFB) coupled to a photovoltaic system. The battery, which employs the Fe2+/Fe3+ redox couple to store energy through a chemical concentration gradient, was electrochemically characterized using different carbon-based electrode materials and operated under solar charging for 25 charge–discharge cycles. A maximum power density of 6.3 W·m−2 was achieved at the cell level, with stable cycling behavior under variable solar irradiance. Coulombic and energy efficiencies remained within ranges of 63–72% and 20–28%, respectively, throughout the cycles. Despite these moderate efficiencies, the system demonstrated a consistent and functional usable capacity. The main limitation identified was a decrease in maximum power after prolonged cycling, attributable to resistance and polarization losses rather than electrolyte instability. These preliminary results characterize the initial performance of the FeCl-CFB under solar-driven conditions, highlighting significant efficiency and stability challenges that must be addressed through further optimization to determine the future potential for decentralized energy storage.
