“I am very pleased to build the first hydrogen bus charging station in Korea. This is because there was active cooperation and efforts of Changwon City, Changwon Industry Promotion Agency officials, and employees of our company for successful implementation. A heartfelt thank you to everyone.”

Wonjin Lee (54), CEO of GTC Co., Ltd., who built the Changwon-seong main hydrogen charging station, said that he would do his best to ensure that the charging station runs smoothly.

Regarding the background of the hydrogen bus charging station, CEO Wonjin Lee decided to use a hydraulic hydrogen compressor after considering various fields to find new food from 4 years ago.

He said, “As we successfully develop localized products in the construction of high-cost hydrogen charging stations, we decided that it would be of some help to reduce the cost of building domestic hydrogen charging stations and expand the supply of hydrogen charging station infrastructure. This can be said to be the main reason for the convenience of users by minimizing the waiting time after charging.”

In fact, it has been reported that users are satisfied with the test charging results for more than a month now.

He emphasized that a large-capacity hydraulic compressor that can compress and store more than 50 kg of hydrogen per hour was applied to this charging station, and that it is a product that can charge two buses. He also explained that the priority control (P-Panel) method for charging a hydrogen bus can be designed and manufactured with its own technology, which can be operated more easily than an existing hydrogen charging station.

GTCC, proud of its 46th anniversary this year, has a lot of achievements in the industrial hydrogen compressor field. In the past, CEO Wonjin Lee of Daesan, Chungnam (formerly KCC) 125HP, Korea PTG Ulsan Plant 450HP, Deokyang Ulsan Plant 500HP, Hyosung Yongyeon Plant (Ulsan) 1,100HP, Deokyang Yeosu Plant 1,500HP, etc. The experience of manufacturing and supplying hydrogen compressors of various capacities ranging from small to large sizes has led to the production of large-capacity hydraulic compressors for hydrogen buses.

CEO Wonjin Lee, who has been steadily devoting himself to the development of hydrogen compressors, received a new technology (NET) certification for hydrogen compressors from the Korea Industrial Technology Association two years ago. At the end of this month, the new product (NEP) certification is coming soon, and it is sparingly investing in the development of new products.

Hydrogen is emerging as a trend with carbon-neutral 2050, so it is a good opportunity for CEO Lee Won-jin.

“Currently, the world is rapidly converting the country’s main energy source from the carbon economy to eco-friendly energy. Hydrogen, the cleanest energy, will bring about innovative changes in the industrial structure and cultivating new growth engines of the economy. In the case of hydrogen refueling stations, T/T with more than twice the capacity will be supplied rather than the existing tube trailer (T/T). By building a pipeline network from the hydrogen production base to the charging station, it is expected that the hydrogen society experienced by users will be realized fairly quickly.”

CEO Wonjin Lee, who is continuously paying attention to trends and trends in the hydrogen industry, adopted a compression method that has advantages in medium-pressure compression (diaphragm) and ultra-high pressure compression (hydraulic piston) to configure the system in a multi-stage complex type for the first time in Korea and in the world. He emphasized that research on technology that can handle 85 kg is in progress.

“A hydrogen refueling station can satisfy customers only when there is no defect in operation, even for a moment. With the modularization of core equipment, we plan to introduce a system that does not stop the operation of the charging station by applying a system that is designed and manufactured so that the other compressor can be operated even if the charging station compressor fails.”

CEO Wonjin Lee said that a hydrogen economy society is essential to reduce fine dust and carbon dioxide, which are becoming global issues. I emphasized that it should be made compulsory through laws and regulations.

“Based on the solid technology and know-how that all of our executives and staff have accumulated over the past 46 years, we believe that GTC’s competitiveness lies in playing a leading role in the compressor business field and actively responding to the changing environment. The technology-dependent form abroad is because there was no independent development of technology. We will contribute to advancing the era of the hydrogen economy by developing our own technology for a new type of high-efficiency compression system to narrow the technological gap with advanced countries and develop a Korean-style hydrogen charging station.”
