Renewable Energy Focus seeks to deliver high-value insights across the energy value chain through integrative, comprehensive, and leading-edge research – covering high impact innovations in renewable energy systems integration; modelling and analysis; policy; and business innovations. At the technology level we publish fundamental and applied research (and insights) on commercially-feasible renewable energy technology development across all vertical technology sectors.

• Decentralisation and its impact on decarbonising the grid
• How should the grid evolve to manage a complex interaction of different energy technology profiles reliably and economically, both in the developed and developing world?
• The role of Digitisation and advanced IT technology to manage, decarbonise, co-ordinate and optimise the grid (and assets associated with it).
• How will market forces need to adapt to facilitate an energy transition (for example with regard to Social and consumer attitudes and behaviour; supply and demand; and the economics of integrating different technology profiles).
• How do the Power markets need to evolve to encourage continued investment in a broad and diverse range of technology profiles and energy systems – many of which have conflicting grid requirements, performance and outputs.
• What do we need to do to make the electrification of transport possible?

The journal publishes research studies about renewable energy systems (Solar, Wind, biomass, etc.) and their technical, economic and environmental applications. An extended version of the high quality selected submissions from IREC2026 will be recommended for publication in Renewable and Sustainable Energy Reviews Journal. Only new technology analyses with respect to existing literature and original research papers that have a significant review amount (critique, comparison, or analysis) will be considered. Bibliographic literature reviews, as well as country specific reviews are not suitable.

Modern grids must adopt the advancements in zero-energy buildings, sustainable cities and solar thermal energy, which are expected to replace the traditional electrical grid. Current research in these areas focuses on enhancing the efficiency, reliability, economics and sustainability of power generation, transmission and distribution systems. At the same time, studies addressing the challenges related to the integration of solar thermal energy, energy management in buildings and cities, demand distribution, load automation and control, and the commercial implementation of these sustainable technologies, are emerging. This special issue will explore the requirements, challenges, and latest innovations in zero-energy buildings, sustainable cities and enhancements in solar thermal energy.

Extended versions of selected papers will be publishable in Energy and Built Environment (Elsevier). The topics covered are:

• Advancement in Zero Energy Buildings and Sustainable Cities infrastructures and renewables integration.
• Energy distribution and management improvement in Zero Energy Buildings and Sustainable Cities.
• Integration of solar thermal systems for enhanced energy efficiency and sustainability.

Energy is characterized by several aspects ranging from the generation ways to its sustainability, through conservation, transformation, use, transfer, storage, etc. The present Special issue considers all these various aspects but particularly focussing on Hydrogen energy upon which most of the energy economy policies are nowadays based due to its outstanding properties like the possibility for its transformation into a valuable renewable and clean energy source, excluding any emissions, greenhouse effect, toxicity, etc. However all these different aspects are under explored, hence encouraging the consideration of sensitive issues like its production, storage, valorization, etc. which are mainly influenced by the small size of the hydrogen molecules, requiring sufficiently high pressure conditions for a reasonable energy density easing its storage. Also the natuaral volatilty of hydrogen and its highly flammabity do make it difficult to transport. Therefore, all these factors are challenges motivating the consideration of this source of energy. The proposed Special Issue aims to examine the recent achieved advances and the resulting applications, by inviting academic scientists and researchers. Various topics may be treated like: Modeling and simulation; Process optimization, Energy efficiency; Non-conventional processes, etc., regarding Hydrogen energy but in the same time without excluding other energy types.

Corresponding papers will be peer reviewed by specialized and experienced reviewers and eventually accepted for publication in Energy Engineering journal.
