Prof. Hwang signed a technical advisory contract with DIG AirGas on 29th July, 2021. 

He will provide DIG AirGas with a lot of his experience and knowledge in cryogenic liquefaction technology. Both parties are willing to build an innovative hydrogen liquefaction plant with high technical and economic value in the next few years. 

The first target project would be a pilot LH2 plant, which will be built in Energy Valley, Naju in 2025, and both parties would do their best to achieve this goal.
