Korea’s largest utility KEPCO (Korea Electric Power Corporation) has successfully conducted LOHC (Liquid Organic Hydrogen Carriers) tech demonstration, the company stated on March 9.

The demonstration proved a 20Nm3 scale concept possible, KEPCO said. As a relatively young technology, most of the researches on LOHC so far has had a scale under 1Nm3, the company added. The latest demo by KEPCO had acquired safety and tech certificates from Korea Gas Safety Corporation (KGS), which is also the first for a LOHC-applied hydrogen storage equipment.

KEPCO used Dibenzyltoluene (DBT) as the hydrogen carrier. When catalyzed under certain conditions (50-180℃, 50atm), hydrogen is absorbed into the carrier. Hydrogen can be released from the carrier when catalyzed under 250℃ and 3atm. The carrier can be reused, KEPCO explained.

KEPCO said that 100 liters of LOHC can refuel a hydrogen car, assumed the vehicle’s 5kg of hydrogen capacity, without any hydrogen leakage over a year.
