Published: Sept. 13, 2022

The Middle East and North Africa (MENA) countries are rapidly growing in population with very limited access to freshwater resources. To overcome this challenge, seawater desalination is proposed as an effective solution, most MENA have easy saline water. However, processes massive demand for energy, which mostly met by fossil fuel-driven power plants. rapid technological advancements renewable energy technologies, along their gradually decreasing cost place energy-driven plants a promising alternative conventional fuel-powered plants.In the current work, energy-powered region investigated. Various technologies resources, particularly those available discussed. A detailed discussion of suitable storage incorporation into systems also included.The progress made implementing summarized analyzed describing overall trend giving recommendations potential amalgamation energies (REs) technologies. Finally, case study region, Al Khafji solar reverse osmosis (SWRO) plant Kingdom Saudi Arabia KSA, used demonstrate implementation REs drive processes.

Techno-economic feasibility of integrating hybrid battery-hydrogen energy storage system into an academic building

Energy Conversion and Management, Journal Year: 2024, Volume and Issue: 309, P. 118445 - 118445

Published: April 25, 2024

Green hydrogen production and storage are vital in mitigating carbon emissions sustainable transition. However, the high investment cost management requirements bottleneck of utilizing hybrid hydrogen-based systems microgrids. Given necessity cost-effective optimal design these systems, present study examines techno-economic feasibility integrating into an outdoor test facility. With this perspective, several solar-driven scenarios introduced at two energy levels, namely battery including high-pressure gaseous metal hydride tanks. Dynamic simulations carried out to address subtle interactions components system by establishing a TRNSYS model coupled Fortran code simulating system. The OpenStudio-EnergyPlus plugin is used simulate building load, validate against experimental data, according measured data monitored operating conditions. Aimed enabling efficient integration techno-enviro-economic optimization algorithm developed simultaneously minimize levelized electricity maximize CO2 mitigation each proposed scenario. results indicate that storages photovoltaic-alone scenario enhances 22.6% 14.4% annual renewable factor. Accordingly, inclusion gives 30.4% 20.3 % boost factor value, respectively. Although increases factor, imply it reduces rate via electrolysis. optimized values emission for different vary range 0.376–0.789 $/kWh 6.57–9.75 ton, multi-criteria optimizations improve up 46.2% 11.3%, with respect their preliminary design.

Enhancement of a radiant floor with a checkerboard pattern of two PCMs for heating and cooling: Results of a real-scale monitoring campaign

Applied Thermal Engineering, Journal Year: 2024, Volume and Issue: 246, P. 122887 - 122887

Published: March 6, 2024

When integrated in radiant floor, phase change materials (PCMs) enable the system to store and release thermal energy winter efficiently mitigate heat gains summer. Although a large number of studies examined performance floors with PCMs, most works conducted numerical analysis. Only few experimentally investigated PCM floors, they were limited laboratory set-ups. In addition, nearly all focused exclusively on space heating. A floor enhanced PCMs was at large-scale within H2020 European project IDEAS. The composed two types one for heating cooling, installed building demonstrator equipped an existing air handling unit (AHU). Data showed that summer loads absorbed by during day. Heat then released night maintain indoor temperature close setpoint. winter, AHU allowed achieve 13 % savings compared sole AHU. storage setpoint 20 °C from 9 h up almost 30 after switching off systems.
