Special Issue Information

Dear Colleagues,

Innovative, Hybrid Energy Solutions and Technologies demonstrates a pivotal pathway toward achieving sustainability and decarbonization goals through reliable and zero-/low-carbon energy systems and approaches. By combining multiple renewable and conventional energy sources with energy storage methods, hybrid systems can overcome the challenges and limitations of individual technologies while improving overall efficiency and resilience. Innovative and advanced approaches in energy production, storage, conversion, and optimization—integrated with environmental and health considerations—further support the deployment of these systems, enabling flexible energy management as well as improved energy security and equity. Moreover, hybrid techniques can be tailored to the specific needs of remote, rural, or urban communities, reducing dependency on fossil fuels and contributing to sustainable development. Continued research and development in this field are essential to unlocking cost-effective, scalable solutions that can accelerate the global energy transition.

This Special Issue focuses on addressing critical knowledge gaps associated with innovative and hybrid energy solutions and technologies for the development of cleaner environments. It aims to showcase cutting-edge research that advances the adoption of these solutions and technologies to promote environmental quality while ensuring energy access and security.

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

  • Applications of innovative and hybrid energy solutions and technologies in building, industrial, and agricultural sectors;
  • Applications of Artificial Intelligence (AI) in hybrid energy systems and technologies;
  • Energy and exergy analysis of hybrid energy systems;
  • Smart, energy-efficient, and net-zero energy buildings;
  • Energy sustainability, resilience, and climate adaptability in hybrid energy systems;
  • Smart, hybrid energy storage systems;
  • Energy efficiency improvements;
  • Decarbonization strategies through innovative technologies;
  • Environmental risk assessments of hybrid energy systems;
  • Social, economic, and policy aspects surrounding hybrid energy systems;
  • Climate change mitigation and sustainability;
  • Energy equity, security, and access;
  • Advanced energy storage and conversion technologies.

Original research articles, review articles, case studies, and technical notes are welcome for submission to this Special Issue.

Samothrace is a Greek island in the northern Aegean Sea. Though connected to the mainland grid and demonstrating strong wind potential, it is challenged by seasonal shortages in both electricity and potable water. This study assesses a Hybrid Renewable Energy System designed to meet local energy and water demands while maintaining economic viability. The system consists of 10 wind turbines (23.5 MW), a reverse osmosis desalination plant yielding 876,000 m3/year, and four alternative storage configurations: green hydrogen, pumped hydro, lithium-ion batteries, and a combined green hydrogen–pumped hydro option. Using identical climatic and demand data, system performance was simulated for the years 2011–2020. Wind generation reached 113,000 MWh annually, of which 81–84% was exported to the mainland. Potable water demand was met at a rate of 99% in all scenarios, with monthly production ranging from 17,500 m3 in February to almost 50,000 m3 in August, thus requiring 1.80% of wind output. Investment costs ranged from 34.4 M € to 39.8 M €; net present values remained around 75 M € for all scenarios. Results demonstrate that complete autonomy can be achieved; however, economic sustainability is maximized by leveraging the interconnection and sizing storage below full-autonomy levels. Full article
