Korea Electric Power Corp. (KEPCO) said on March 9 that it has succeeded in proving that it can store 20 Nm3 of hydrogen per hour by using “Liquid Organic Hydrogen Carries (LOHC) technology” for the first time in Korea.
LOHC technology, which began in 2017, has so far remained at the basic level of research conducted only on a small scale of 1 Nm3, but KEPCO has succeeded in verifying LOHC storage technology, which stores 20 Nm3 of hydrogen per hour for the first time in Korea.
In addition, KEPCO is the first corporation to receive technical reviews of general manufacturing facilities for high-pressure facilities for hydrogen storage facilities with LOHC and certificate of completion of gas-use facilities from Korea Gas Safety Corporation.
Current domestic hydrogen storage technology is limited to the existence of high cost and risk of hydrogen compression and storage at high pressure more than 200 times atmospheric pressure and transport to tanks.
The new LOHC technology allows safe storage and transport of hydrogen by storing it in liquid compounds and also makes transportation costs cheaper.
"LOHC is significantly higher in storage capacity, stability and economy than conventional compressed storage methods," a KEPCO official said. "We will continue to do our best to develop various energy technologies in keeping with the government's eco-friendly policies."
