A joint venture between Plug Power, an American provider of hydrogen fuel cell turnkey solutions, and its South Korean partner, SK E&S, will build a major plant in a high-tech industrial zone in the western port city of Incheon to produce fuel cells and water electrolysis facilities targeting Asian markets. Production is to begin in 2024.

Plug Power and SK E&S, an energy company affiliated with South Korea's third-largest SK Group, have signed an agreement with the Ministry of Trade, Industry and Energy to build the so-called "Giga" factory. The exact amount of investment was not disclosed, but the ministry said the project in Incheon would attract the largest amount of foreign investment ever in South Korea's hydrogen sector.  Water electrolysis technology decomposes water with electricity to produce hydrogen. Hydrogen companies have been testing various methods to improve water electrolysis technologies to effectively produce hydrogen because of its high production costs. 

SK E&S and Plug Power have established a joint venture called "HALO Hydrogen" to create a hydrogen ecosystem in South Korea. Using Plug Power's know-how in operating and distributing liquefied hydrogen charging stations, the joint venture will distribute liquefied hydrogen to more than 100 charging stations in South Korea.
 
The joint venture plant is aimed at supporting Incheon's plan to revitalize hydrogen public transportation and use hydrogen for all 2,000 city buses by 2030. Various commercial vehicles such as large trucks, wide-area buses, and cleaning vehicles would gradually use hydrogen. SK E&S and Plug Power are in charge of building and operating hydrogen charging stations.
