Realizing the dream of clean and infinite energy
We lead the way to a brighter future. While enabling renewable energy system,
Greenable contributes to building a sustainable and stable energy market.
As a major energy source, hydrogen is redefining our industries and economies. Greenable™ offers safe solutions for the hydrogen economy with product portfolio spanning the entire hydrogen value chain: from production to delivery, storage and use.
Steel Pipes for Hydrogen Delivery
This welding pipe boasts the world's highest safety standards, able to withstand impacts even at temperatures as low as -45°C. Structures utilizing this solution have been established for the first time in Korea, specifically in the hydrogen pilot cities of Ansan and Ulsan. Additionally, the development of steel products and welding solutions for large-diameter steel pipes designed for high-pressure hydrogen is currently underway.
Conventional high-pressure hydrogen tanks have a maximum capacity of 550L. After use, it takes maximum 15 minutes to restore the pressure level and be ready for refueling again. To address this issue, POSCO is developing a safer alternative which has a capacity of 1000L or more.
Currently, carbon fiber is used to reinforce hydrogen tanks in vehicles. POSCO is developing an alternative with steel wire that is greener and more affordable.
