Energy storage and saving technologies: a review on SDEWES 2023 special issue

The 18th Conference on Sustainable Energy, Water and Environmental Systems (SDEWES) served as a global meeting point for scientists, engineers, and decision-makers to exchange ideas on integrated resource management. This editorial introduces the curated special-issue articles, distilling their contributions and mapping their intersections across energy, water, and environmental systems. Rather than offering an exhaustive survey, it foregrounds the questions and debates that emerge from the collected work, situating them within current scholarly and policy conversations. By highlighting recurring motifs, including technological innovation, life-cycle assessment, and governance frameworks, the piece clarifies the journal’s perspective on pressing sustainability dilemmas and points readers toward actionable insights.
