Published at Chemical Engineering Science – Experimental screening of metal nitrides hydrolysis for green ammonia synthesis via solar thermochemical looping

Abstract: Ammonia is a fundamental chemical commodity for fertilizers and as a novel energy vector. Solar-driven ammonia synthesis is proposed as a sustainable alternative to the catalytic energy-intensive and CO2-emitting Haber-Bosch process. The considered thermochemical process aims to produce ammonia from nitrogen and water (N2 + 3H2O → 2NH3 + 1.5O2) via redox cycles using a solar heat source, thus bypassing …

Solar Energy Materials and Solar Cells – Incorporation of CaZrO3 into calcium-based heat carriers for efficient solar thermochemical energy storage

Abstract Calcium-based materials (CaCO3/CaO) have shown significant potential for use in thermochemical energy storage systems for concentrated solar power generation due to their low-cost, high-energy storage efficiency, and operational temperature range. However, the energy storage performance of calcium-based heat carriers degrades rapidly over cycles due to high-temperature sintering, limiting practical applications. In this study, we …

Published at Renewable Energy – Feasibility study: Economic and technical analysis of optimal configuration and operation of a hybrid CSP/PV/wind power cogeneration system with energy storage

Abstract: In this study, a hybrid photovoltaic-wind-concentrated solar power renewable energy system and two cogeneration models are proposed. Evaluation criteria are employed, including the levelized cost of energy (LCOE) and the loss of power supply probability (LPSP). The optimal configuration and dynamic dispatch strategy of the hybrid system are determined through multi-objective optimization using the …
