SEOUL -- Using fuel cells that simultaneously produce hydrogen, electricity and heat, SK energy, a leading refiner in South Korea, will demonstrate an on-site hybrid energy station capable of generating green energy and using it directly for charging.

Doosan Fuel Cell, the clean energy wing of South Korea's Doosan Group, will provide its "Tri-gen" fuel cell system that generates electricity, heat and hydrogen utilizing 440-kilowatt phosphoric acid fuel cells (PAFC). SK energy will supply a facility that can produce high-purity hydrogen. 

The two companies will complete the demonstration of a facility, which can produce high-purity hydrogen of 99.99 percent or higher in the first half of 2023, and install a commercial on-site complex energy station that can charge electric and hydrogen cars simultaneously. One hydrogen charging station can produce about one ton of hydrogen per day, which can charge some 200 hydrogen cars or 30 hydrogen trucks.

"We will reduce power transmission and distribution losses and hydrogen distribution costs through Tri-gen and the development of high-purity hydrogen production technologies to optimally supply eco-friendly energy to customers and contribute to revitalizing the hydrogen economy," SK Energy's solution and platform business division head Kang Dong-soo said in a statement on November 22.

Tri-gen can be used to build complex energy charging stations. The two companies will expand their hydrogen charging station business gradually by 2026. Hydrogen fuel cells use hydrogen as fuel to produce electricity. Because hydrogen fuel cell power generation systems are much smaller than thermal power plants or hydropower plants, they are ideal for providing power to microgrids, which are networks of small, isolated smart power grids, in urban environments.
