Interests in hydrogen are rapidly growing due to its potential to establish global clean energy supply chains.
A typical method of hydrogen storage is physically storing hydrogen such as compression or liquefaction, which requires higher energy to increase storage capacity and expensive distributing infrastructure.To overcome these limitations, research efforts to store hydrogen chemically in liquid carriers, such as liquid organic hydrogen carriers (LOHCs) or ammonia, have been conducted.
Hydrogen can be safely stored in LOHCs at room temperature and atmospheric pressure before being extracted at locations for hydrogen consumption.
Various organic compounds have been suggested for LOHCs. However, there were few comparative studies on LOHC performance, leading to a lack of scientific consensus in the hydrogen community for downselecting LOHCs and catalysts - link - National Research Council of Science & Technology - link - more like this - link
