Carbon Capture, Utilisation & Storage

CCS/CCUS attract attention as a solution for achieving carbon neutrality all over the world.

Therefore, an increasing amount of steel pipe being used as a CO2 injection tubing. JFE’s martensitic steel show certain amounts of corrosion resistance on CO2 gas with contamination environments. The result was that JFE’s material can be applicable for the CO2 injection tubing.

For steel pipe connection, we conducted low temperature connection tests which is JFE’s own unique way of simulating actual CCS/CCUS operations, using JFE’s premium connection “JFELION”.
