Steel Enables a Green Tomorrow

Greenable™, Renewable Energy Enabler

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.

H2 Ecosystem

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

Unrivaled resistance to weld cracking and corrosion

Greenable™ delivers long-lasting, high-durability pipes to withstand weld cracking and corrosion caused by H2. They are the safest of its kind as they can withstand temperatures down to -45°C (-49°F) when welded. These pipes made of hot rolled steel was first applied to the Ansan Hydrogen Pilot City in engea.

Hydrogen storage tanks for H₂ stations

High-pressure storage tanks with improved safety

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.
