Sessions / special issues

This Special Issue will include papers on Materials and Clean Processes for Sustainable Energy and Environmental Applications: There is an overwhelming compulsion in the development of new materials aiming to reduce the environmental impact of processes in the energy field and to adapt their properties to target applications. Generally, materials developed for specific applications are reconverted for other uses and slightly modified to reach higher performances. A different approach is to create new and target materials for a definite application by varying the synthesis and activation conditions and methodology during preparation. This way, numerous new materials have recently been developed for specific applications in the field of energy. Thanks to the advances in material science, several gas/energy storage and production processes have been transformed/reconverted into clean processes (biofuel industry, fatal energy recovery, renewable energy storage, exhaust gas treatment, wastewater treatment, etc.). The topic of this Special Issue is the implementation of new materials in clean processes in the energy field:

• Biosourced material for energy recovery (biofuel, chars, etc.);
• Materials and composites for energy storage (PCM, salt hydrate, zeolites, etc.);
• Materials and catalytic materials for energy related processes (biofuels production and purification, biogas purification, etc.).
• Exhaust gas treatment
• Wastewater treatment technologies;
• Innovative technologies for the removal of emerging pollutants;
• Sewage bio-solids management (methanisation, composting,

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?

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.

The production of biohydrogen from wastewater offers a sustainable solution to meet energy demands while simultaneously addressing wastewater management challenges. Various techniques, such as dark fermentation and photo fermentation, may fulfill these aims by treating domestic and industrial wastewaters. These wastewaters are abundant in organic nutrients, promoting the growth of hydrogen-producing microorganisms. The effectiveness of these processes is influenced by factors such as substrate composition, microbial communities, and environmental conditions. Biohydrogen production is highly appealing due to its efficiency, low environmental impact, sustainability, and economic viability. Therefore this is a great motivation to launch a Special Issue where the aims is to review the recent advances made related to hydrogen energy and the resulting applications, by providing ideal conditions to gather scientists, researchers, engineers around that issue. Different topics may be considered like: Process modeling and simulation; Process optimization, Energy efficiency; Non conventional processes, etc. Also the opportunity will be given for research works dealing with any clean and efficient hydrogen production from biomass, to be presented within this special issue.

Corresponding papers will be considered and eventually published in Water journal | An Open Access Journal from MDPI, if accepted after a reviewing process by assigned qualified reviewers.
