Human activities have significantly increased greenhouse gas emissions, with transport contributing a substantial portion. In response to the Paris Agreement's net-zero emission target by 2030, hydrogen emerges as a crucial energy carrier in sectors like transport, power generation, and manufacturing. Hydrogen fuel cell vehicles (HFCVs), such as Toyota Mirai and Hyundai Nexo, are gaining traction as sustainable options. However, the growth of HFCVs necessitates a robust network of hydrogen refuelling stations worldwide. While current hydrogen production heavily relies on natural gas and faces limitations, the shift towards 'green hydrogen' generated from renewable sources offers a cleaner alternative. Liquid organic hydrogen carriers (LOHC) present a promising technology for hydrogen storage and transportation. Materials like methylcyclohexane, toluene, dibenzyltoluene, and N-ethylcarbazole are highlighted for their potential as efficient hydrogen carriers. Research on LOHCs emphasizes their thermodynamic properties, safety, scalability, and economic viability, indicating a positive direction towards sustainable hydrogen solutions.
