Abstract

Harvesting energy from the ambient is a promising approach to fulfil decentralized energy demands and facilitate the transition to low-carbon economy. Moisture-sorption-based energy harvesting (MSEH) is a promising strategy for obtaining heat, cold and electricity from ubiquitous moisture anywhere and anytime. Advances in water-sorption materials have promoted the development of sustainable moisture energy. However, MSEH technology faces the challenges of low-energy productivity and limited recognition of its working mechanisms and thermodynamic analysis. We centre this Perspective article around an in-depth understanding of the underlying mechanisms and thermodynamic limitations of sustainable moisture energy. We first introduce the working principles of MSEH for heat, cold and electricity generation, and summarize recent progress in water sorbents. We then discuss thermodynamic limitations and evaluate global potential for sustainable moisture energy. We outline future challenges of water-sorption kinetics and propose technical directions for accelerating water sorption-desorption with ordered cross-scale energy transfer and mass transport. Finally, we offer an overview of future research areas for water sorbents with higher water uptake, tunable water affinity and faster water sorption for next-generation high-performance MSEH. Moisture-sorption-based energy harvesting (MSEH) is a promising strategy for obtaining heat, cold and electricity from ubiquitous moisture anywhere and anytime. This Perspective article discusses the thermodynamic characteristics of MSEH, evaluates global energy production potential and highlights challenges and strategies for realizing high-energy-productivity MSEH.

可持续湿能源

从周围环境中收集能源是满足分散能源需求和促进向低碳经济过渡的一种很有前途的方法。基于湿气吸附的能量收集（MSEH）是一种前景广阔的战略，可随时随地从无处不在的湿气中获取热量、冷量和电能。吸水材料的进步推动了可持续湿能源的发展。然而，MSEH 技术面临着能源生产率低、对其工作机制和热力学分析认识有限等挑战。本视角文章将围绕深入了解可持续湿能源的基本机制和热力学局限性展开。我们首先介绍了用于制热、制冷和发电的 MSEH 的工作原理，并总结了水吸附剂方面的最新进展。然后，我们讨论了热力学限制，并评估了可持续湿能源的全球潜力。我们概述了水吸附动力学的未来挑战，并提出了利用有序的跨尺度能量传递和质量传输加速水吸附-解吸的技术方向。最后，我们概述了为下一代高性能 MSEH 提供具有更高吸水率、可调水亲和性和更快吸水速度的吸水材料的未来研究领域。
