Doosan to construct first liquid hydrogen plant

Apr 24,2019
Doosan Heavy Industries & Construction, Korea’s top power equipment maker, said Tuesday it will construct the country’s first liquid hydrogen production facility.

Doosan Heavy said that the liquid hydrogen plant will be built in the southern port city of Changwon, South Gyeongsang, by 2021. The company and the municipal government of Changwon met to sign an agreement on Tuesday.

The flagship unit of Doosan Group said the construction project is estimated to cost 35 billion won ($30 million), a large chunk of which will be financed by the Changwon municipal government.

The municipal government will also offer land for the project and help in creating partnerships in the neighboring industrial complex.

Doosan Heavy will participate in building and maintaining the facility.

The new plant aims to produce 0.5 tons of liquid hydrogen per day that would be sent to places like hydrogen charging stations.

Hydrogen in Korea is currently distributed as a gas, which takes more space than storing it as a liquid. A smaller storage space means less operation costs as it requires less land. Hydrogen turns into a liquid when it reaches the cryogenic temperature of minus 253 degrees Celsius (minus 424 degrees Fahrenheit).

Doosan Heavy also manufactures heat exchangers and high-pressure storage tanks, key components for hydrogen fueling stations.
