“CO is a bit more demanding”, because 2 of its properties as a dense phase, when it depressurizes, maintains an evaporation pressure for a very long period, so cracks continue to grow. That drives a require- ment for increased toughness, “which is ? ne if you’re building a new pipeline; not so easy if you have an existing pipeline so we have to be a bit careful about that one.”

CO also likes to dissolve polymers, so 2 traditional pipeline inspection gauges could be a problem, but this is being looked at by the likes of Rosen and oth- ers, said Cooper.

Monetizing CO 2

Marc MacDonald Head of Clean Fu- els at TÜV SÜD National Engineering

Laboratory in Scotland also raises an- other challenge – being able to measure

CO as a ? uid, particularly as it’s subject 2 to phase changes, which could lead to measurement inaccuracies. That’s impor- tant, he said. “Whether through taxation, carbon credits or some other means, CCS schemes will be monetized; we already have an accuracy requirement ±1.5% of mass from the EU ETS.

“In the future, ? ow meters will likely act as ‘cash registers’ for CCS schemes, as they do currently for the oil and gas sector. Of course, measurement inaccu- racy undermines the technical and eco- nomic viability of these schemes.” For these reasons, TUV SUD National En- gineering Laboratory is researching how measurement practices for CO can be 2 improved.

There are many questions, but it’s still an opportunity, says Rogerson. “No one has written the book on this yet and it’s all to play for.” He says pilot projects onshore currently make more sense, but
