Special Issue Information

Dear Colleagues

The global demand for sustainable and efficient energy systems has intensified research into new sources of energy and fuels. As society transitions toward low-carbon and renewable energy solutions, the development of innovative technologies for energy generation, storage, and utilization is critical. This Special Issue of Applied Sciences, titled “Advances in New Sources of Energy and Fuels”, highlights recent advances in the exploration, development, optimization, and utilization of novel energy sources and alternative fuels.

Key areas of the focus include renewable energy technologies such as solar, wind, and bioenergy, as well as emerging approaches like hydrogen production, synthetic fuels, and energy harvesting from unconventional sources, including gas hydrates and advanced fuel systems. Contributions also address innovations in fuel cell systems, carbon capture and utilization (CCU), and energy storage methods to bridge intermittent energy supply challenges.

This Special Issue places particular emphasis on interdisciplinary approaches that integrate engineering, material science, and environmental considerations to advance energy sustainability. Through experimental studies, computational models, and case studies, these contributions aim to address global energy challenges while minimizing environmental impacts. By showcasing state-of-the-art research and novel insights, this Special Issue aims to inspire future breakthroughs in energy and fuel technologies, contributing to a sustainable and energy-secure future. We invite researchers, engineers, and policymakers to engage with these advancements within the global scientific community.

The growing need for sustainable energy solutions has propelled the development of Hybrid Renewable Energy Systems (HRESs), which integrate diverse renewable sources like solar, wind, biomass, geothermal, hydropower and tidal. This review paper focuses on balancing economic, environmental, social and technical criteria to enhance system performance and resilience. Using comprehensive methodologies, the review examines state-of-the-art algorithms such as Multi-Objective Particle Swarm Optimization (MOPSO) and Non-Dominated Sorting Genetic Algorithm II (NSGA-II), alongside Crow Search Algorithm (CSA), Grey Wolf Optimizer (GWO), Levy Flight-Salp Swarm Algorithm (LF-SSA), Mixed-Integer Linear Programming (MILP) and tools like HOMER Pro 3.12–3.16 and MATLAB 9.1–9.13, which have been instrumental in optimizing HRESs. Key findings highlight the growing role of advanced, multi-energy storage technologies in stabilizing HRESs and addressing the intermittency of renewable sources. Moreover, the integration of metaheuristic algorithms with machine learning has enabled dynamic adaptability and predictive optimization, paving the way for real-time energy management. HRES configurations for cost-effectiveness, environmental sustainability, and operational reliability while also emphasizing the transformative potential of emerging technologies such as quantum computing are underscored. This review provides critical insights into the evolving landscape of HRES optimization, offering actionable recommendations for future research and practical applications in achieving global energy sustainability goals.
