Hydrogen Energy

Design, construction, operation and after service of hydrogen charging station

Self-operating the West Busan NK Hydrogen Station

Through the private capital assistance project of the Ministry of Environment, we are building the first Busan NK hydrogen filling station in Busan to conduct hydrogen energy business and provide total solution services from design to construction, operation and after-sales service. This is the cradle of NK Group, which aims to transform itself into a hydrogen-based 'hydrogen economy' to use energy as an eco-friendly environment while being an economic engine of innovation.
