Large-scale stationary hydrogen storage via liquid organic hydrogen carriers

Zainul Abdin et al.

Summary: Liquid organic hydrogen carriers (LOHCs) have emerged as a favorable storage medium for large-scale stationary hydrogen storage due to their low cost and compatibility. While ammonia and methanol are also attractive options as large-scale hydrogen carriers, their synthesis and decomposition are energy and capital intensive. Therefore, LOHCs could be a possible option for large-scale stationary hydrogen storage, considering factors such as safety and cost.
