Pursuing Commercialization of Large-Capacity, Low-Pressure, High-Safety Hydrogen Storage Technology

Sungwon Industries announced on March 19 that it has developed and successfully demonstrated a large-capacity hydrogen storage system using hydrogen storage alloy-based solid hydrogen storage technology, under low-pressure and high-safety conditions.

While solid hydrogen storage technology is being considered as a potential energy storage method for renewable energy sources such as solar and wind power, technical challenges have been identified: despite its high safety, delays in the absorption and release of hydrogen, as well as burdens related to heat and energy management, have been pointed out.

Sungwon Industries addressed these issues by securing improved storage and control technology, and advanced the technology to enhance system operation efficiency and applicability. By focusing on its proprietary control algorithm, thermal management technology, and pressure vessel design capabilities, the company completed a 'large-capacity hydrogen storage pressure vessel based on hydrogen storage alloy' that can operate efficiently even in real-world environments.

The pressure vessel was developed as a 0.3㎥ class unit capable of storing more than 10kg of hydrogen, and has been expanded to a 1.0㎥ class unit that can store more than 40kg of hydrogen. Demonstrations under low-pressure and high-safety conditions have also been completed. It has also passed the product inspection for gas equipment by the Korea Gas Safety Corporation (KGS).

A representative from Sungwon Industries evaluated this achievement as "the result of concretizing the demonstration system based on the company’s accumulated technological capabilities, participation in the Global TOP Strategy Research Group project, and technical collaboration with Korea Institute of Industrial Technology."

In addition, Sungwon Industries signed a technology transfer contract worth 100 million won with Korea Institute of Industrial Technology, completing the development of a hydrogen storage alloy vessel with improved heat exchange efficiency during hydrogen absorption and release. The company is currently pursuing further advancement and commercialization of the related system.

Jung Jongtae, CEO of Sungwon Industries, stated, "The hydrogen infrastructure must be verified not only in terms of technology, but also in terms of safety standards and economic feasibility," adding, "Based on the technology transfer and collaboration with Korea Institute of Industrial Technology, we will actively work to expand into the market."
