Published at Solar Energy – Effects of concentrated solar–integrated packed-bed thermal energy storage operation on solid oxide electrolysis cell performance

Abstract: The use of renewable energy in the context of green hydrogen production requires suitable energy storage technologies to compensate for intermittent wind and solar resources. High-temperature electrolysis is a promising way to produce hydrogen as it has the highest electrical efficiency by using steam instead of liquid water compared to low temperature electrolysis. Here, …

Published at Applied Thermal Engineering – Dynamic heat transfer model for thermal energy storage using metal wool–phase change material composites

Abstract: Decarbonisation of the energy sector is critical for climate change mitigation, with the power sector remaining a major contributor to global emissions. Concentrating solar power (CSP) technology combined with thermal energy storage (TES) presents a promising solution to overcome this challenge. TES systems, particularly those utilising phase change materials (PCMs), offer efficient energy storage …

Published at Sustainable Energy Technologies and Assesments – On-sun performance and stability of graphene nanofluids in concentrating direct absorption solar collectors

Abstract: The Performances of direct absorption solar collectors (DASC) are limited by the stability of the nanofluid’s optical properties. This study investigates the performance and long-term stability of a graphene-based nanofluid under real on-sun operating conditions using an experimental parabolic trough pilot. The on-sun experiments were complemented with a detailed off-sun experimental evaluation of the …
