Sunbo Unitech Co., Ltd., which stands out in new eco-friendly and energy businesses, has successfully delivered water electrolysis facilities that can produce 300kW of green hydrogen for the first time in Korea.

 

The water electrolysis facility is a technology that produces high-purity green hydrogen by electrolyzing water. Green hydrogen produced by water electrolysis technology utilizes electricity generated from renewable energy and is known as future eco-friendly hydrogen because it does not emit any pollutants (carbon). PEM (polymer electrolyte membrane) water electrolysis facilities are considered to be highly efficient due to their high productivity, ease of responding to volatility in power production, and low site size burden. Although related technologies are in the commercialization stage overseas, it is significant that Sunbo Unitech Co., Ltd. and Elchemtech succeeded in developing them for the first time in Korea.

 

Sunbo Unitech Co., Ltd. believes that the completeness of the 300kW water electrolysis facility has reached the highest level at home and abroad as a result of steadily developing and improving PEM water electrolysis facilities in cooperation with Elchemtech. In particular, Stack, a key technology for water electrolysis, reflected the optimal technology through many improvement processes, such as Sunbo's suggestion of improvement directions to Elchemtech. This 300kW Stack was assembled inside the shipbuilder and completed the test, proving the core capabilities of the shipbuilder, including its own production capabilities.

 

Based on the development process using EPC (bulk order) know-how that provides one-stop shipbuilding and land plant design, parts and materials procurement, and construction, Sunbo Unitech Co., Ltd. delivered PEM water electrolysis facilities, the first work of the new business. As a result, it was possible to provide an opportunity for domestic and overseas expansion in the full-scale commercialization stage.

 

Starting with supplying 50kW water electrolysis facilities to the Korea Hydro & Nuclear Research Institute last year, Sunbo Unitech Co., Ltd. has continued to increase its performance by completing orders for 300kW this year and 1MW and 2MW next year. Kim Chung-wook, CEO of Sunbo Unitech Co., Ltd., said, "Korea's PEM water electrolysis technology has reached a world-class level, and based on these technologies, we are preparing to enter the renewable energy-rich U.S., Australia, Canada, and the Middle East."
