热化学储能材料具有比潜热或显热储能材料高得多的能量密度的优点。金属氢化物具有良好的可逆性和循环稳定性，且焓高。它们可用于短期和长期储热应用，并可提高太阳能热能生产的整体灵活性和效率。工作温度低于500℃的金属氢化物是过去几年研究和开发的重点。对于新一代太阳能热能发电厂来说，必须开发工作温度在600℃以上的新型氢化物材料并对其进行表征。除了对新型金属氢化物的深入研究外，在这些高温下建造和设计储热系统也是一项挑战。腐蚀问题、氢脆和传热流体的选择是未来研究的重要课题。(C) 2018氢能源出版有限责任公司，由爱思唯尔有限公司出版。版权所有。
Thermochemical energy storage materials have advantage of much higher energy densities compared to latent or sensible heat storage materials. Metal hydrides show good reversibility and cycling stability combined with high enthalpies. They can be used for short and long-term heat storage applications and can increase the overall flexibility and efficiency of solar thermal energy production. Metal hydrides with working temperatures less than 500 degrees C were in the focus of research and development over the last years. For the new generation of solar thermal energy plants new hydrides materials with working temperatures above 600 degrees C must be developed and characterized. In addition to thorough research on new metal hydrides, the construction and engineering of heat storage systems at these high temperatures are challenging. Corrosion problems, hydrogen embrittlement and selection of heat transfer fluids are significant topics for future research activities. (C) 2018 Hydrogen Energy Publications LLC.
