Abstract
Using thermochemical energy storage methods to store energy is increasingly vital for boosting the share of renewable energy in consumption within buildings and industries. This entails harnessing off-peak excess renewable energy, such as electricity or waste heat energy, for storage purposes. While previous research emphasizes the importance of improving reactor performance, comprehensive analysis of the new honeycomb reactor designs is lack. Innovative advancements in maximizing thermal performance within triangular honeycomb reactors are elucidated in this study. This study employs a validated 3-D model to explore the effects of these parameters on heat and mass transfer within a triangular honeycomb reactor. By investigating structural and operational parameters, a novel equilibrium is achieved, amplifying heat exchange efficiency and channeling thermal energy with unprecedented precision. Through a rigorous examination of reactor air velocity distribution, air temperature lift, and outlet air absolute humidity, this research unveils pivotal insights into enhancing reactor efficacy. Notably, the study identifies that increasing the channel thickness by 1.2 times, resulting in energy storage density of 463 kJ/kg. This innovation positions triangular honeycomb reactors at the forefront of sustainable energy management, offering a potential solution for decarbonization such as storing industrial waste heat and harnessing surplus off-peak electricity in buildings.
