Special Issue Information

Dear Colleagues,

As the global population grows and energy demands increase, it is becoming increasingly important to adopt energy sources and technologies that minimize our environmental impact and ensure long-term energy security. The imperative to transition towards a sustainable energy landscape has catalyzed significant research and development efforts across different scientific and technological domains. This Special Issue of Energies seeks to highlight the latest advancements in technologies and materials that are poised to revolutionize the energy sector.

Topics of interest for this Special Issue include, but are not limited to, the following:

  • Renewable energy technologies (solar energy, wind energy, hydropower, biofuel).
  • Energy storage and conversion (batteries, fuel cells, hydrogen energy).
  • Thermal energy storage (sensible heat storage, latent heat storage, thermochemical heat storage).
  • Material science for energy applications (nanomaterials, functional materials, sustainable materials).
  • Impact and significance (environmental impact, economic impact, social impact, climate change mitigation, energy security, mitigation of safety risks).

This Special Issue will provide a comprehensive overview of the latest advancements in technologies, materials, and systems that are driving the transition to a sustainable energy future. By fostering interdisciplinary collaboration and knowledge exchange, it aims to accelerate the development and deployment of innovative solutions to address global energy challenges. By highlighting the impact and significance of sustainable energy applications, researchers can effectively communicate the value of these technologies and encourage their widespread adoption. The insights and findings presented in this Special Issue will be significant for researchers, industry professionals, and other stakeholders involved in shaping the future of energy.

Deep dehumidification is crucial for industrial applications requiring ultra-low humidity levels. Traditional cooling-based dehumidification struggles to achieve low dew points efficiently due to excessive energy consumption and frost formation risks. As an alternative, desiccant-based methods, particularly solid desiccant systems, offer improved performance with lower energy demands. This study experimentally investigates a fixed-bed dehumidification system utilizing a plate-fin heat exchanger filled with a silica gel/calcium chloride composite material. The performance evaluation focuses on the influence of ambient conditions and operating parameters, including air velocity and cooling fluid temperature. Among these, the most influential parameter was the velocity of air. For the tested heat exchanger, an optimum value in the range of 0.4–0.6 m/s was identified. Under optimal conditions, the tested HEX was able to reduce the dew point of air down to −2 °C, achieving a reduction in the humidity ratio up to 13 g/kg. The results indicate that air velocity significantly impacts also heat and mass transfer, with coefficients ranging from 80 to 140 W/(m2 K) and 0.015 to 0.060 kg/(m2 s), respectively. The findings highlight the potential of composite desiccant fixed-bed systems for efficient deep dehumidification, outperforming conventional lab-scale components in heat and mass transfer effectiveness. A comparison with other works in the literature indicated that up to 30% increased mass transfer coefficient was achieved and up to seven times higher heat transfer coefficient was measured.

Water photoelectrolysis cells based on photoelectrochemical water splitting seem to be an interesting alternative to other traditional green hydrogen generation processes (e.g., water electrolysis). Unfortunately, the practical application of this technology is currently hindered by several difficulties: low solar-to-hydrogen (STH) efficiency, expensive electrode materials, etc. A novel concept, based on a tandem photoelectrolysis cell configuration with an anion-conducting membrane separating the photoanode from the photocathode, has already been proposed in the literature. This approach allows the use of low-cost metal oxide electrodes and nickel-based co-catalysts. In this paper, we conducted a study to evaluate the economic and environmental sustainability of this technology, using the environmental life cycle cost. Preliminary results have revealed two main interesting aspects: the negligible percentage of externalities in the total cost (<0.15%), which means a positive environmental impact, and as evidenced by the net present value (NPV), there are potentially financial conditions that favour future investment. In fact, an NPV higher than 150,000 EUR can be achieved after 15 years. Full article
