The calcium-copper looping technology is promising.The aim is to produce hydrogen and capture CO₂ in one step. And do it cost-efficiently.

Innovative looping technology may pave the way for industrial applications. Gas switching combustion may be used for power generation or hydrogen production.

Preem has ambitions of capturing CO₂ from the company’s two refineries on Sweden’s west coast. Tests conducted by Aker Solutions will give Preem important operational experience with carbon capture technology.
