Liquid organic hydrogen carrier (LOHC) materials play a crucial role in hydrogen storage capacity, reaction kinetics, reaction temperature, and reversibility. However, the development and optimization of LOHC materials is limited due to the use of mass-produced materials for bulk hydrogen logistics. Researchers in the Republic of Korea proposed a molecular engineering approach to overcome the limitations of commercial dibenzyltoluene (DBT)-based LOHC systems which have superior physical properties, low price, and low toxicity. They used a new chemical structure, benzyl-methylbenzyl-benzene (BMB) to overcome the limitations of slow reaction kinetics and analyzed the dehydrogenation/hydrogenation pathways. They proposed a streamlined and sustainable engineered method for improved MSH material manufacturing with a high BMB. According to the researchers their research provides a fundamental understanding of DBT-based LOHC systems and new insights into the design of novel LOHC candidates… read more.
