Welltec – a global technology company is moving forward with the development of Project Greensand – an extensive carbon capture and storage project in Denmark. Welltec has started testing the materials for casing pipes that will be used in Project Greensand, to ensure their reliability in the long-run. 

“It is crucial for us that we select the right materials for the dedicated CO2 injection wells for Project Greensand, so in the future we can store CO2 safely in the Danish subsea,” said Søren Reinhold Poulsen, project director for Project Greensand.

Project Greensand will aim to capture CO2 from emitters and store them underground in the subsurface of the Danish North Sea. It is an ambitious initiative, part of the green transition of Denmark that could eliminate more than 13% of the country’s annual carbon footprint. 

The project could store up to 1.5 million metric tons per year of CO2 by the end of 2025 and up to 8 million tons per year by 2030. It is a consortium of 23 different Danish and international partners who contribute with experience and expert knowledge from their respective areas.

One of the members of the project – Welltec, is providing its new 18-m by 5-m test flow loop for corrosion testing to compare the performance of five different materials in a controlled environment.

The company wants to recreate the conditions of the subsea environment of the North Sea and expose the materials to that environment for a long period, to find out which materials are best suited to function over time, according to Linda Nolting Kristensen, technology innovation lead at Welltec.

The winners will be used for Project Greensand’s casing pipes that will run down to the sandstone reservoir, 1,800 m beneath the seabed. The project is also expected to test the first storage of CO2 in the subsurface of the North Sea around the end of this year.
