MacGregor LCO2 bow transfer system connects shore carbon capture to seabed storage

MacGregor has adapted its offshore bow loading technology to handle liquefied CO2, allowing carbon capture plants to pump CO2 directly onto ships and inject it into seabed storage without onshore buffer facilities. The system uses mostly proven hardware, with new components for LCO2's extreme cold and high pressure. Tests with SINTEF and DNV qualification are underway, and a prototype is planned for mid-2027. DNV expects global carbon capture capacity to quadruple by 2030 and grow 30-fold by 2050. The EU-funded COREu project aims to cut annual emissions by 6.8 megatonnes by 2035 and 36 megatonnes by 2050. MacGregor says the system works in wave heights up to 5-6 meters and can handle emergency shutdowns without leaks or dry ice blockages.

This is the missing link for a lot of CCS projects. Onshore storage and conditioning is where costs blow up, so skipping it changes the math. Still, the article doesn't say what the transfer rate is or how many ships it can handle per day. That's the number that actually decides whether this scales.

5-6 meter wave height is decent, but what about the rest of the CCS chain? Loading at the capture plant, ship turnaround time, injection rates at the well. If any of those bottleneck, the bow transfer system isn't the limiting factor. Would like to see a system throughput figure, not just hardware specs.

The COREu numbers are small. 6.8 Mt by 2035 is nothing against EU industrial emissions. This tech helps, but it doesn't solve the policy problem. You still need a price on carbon or a mandate that makes capture worth doing. Without that, better transfer hardware just lowers the cost of a project that still doesn't get built.

Industrial manufacturing is supposed to be 41% of captured CO2 by mid-century. That means cement, steel, chemicals. For those sites, shipping CO2 to offshore storage is often the only option, no pipeline nearby. The 79% proven tech share matters for crew training and maintenance costs. Good to see they thought about that.

MacGregor says 79% of the system is based on its existing bow loading tech, 13% is modified, 8% is new. The new bits are the LCO2 coupler valve and guiding pin. Prototype due mid-2027, DNV qualification ongoing. This is still a few years from commercial use.

Worth reading because it shows CCS is moving from pilot to logistics problem. The hard part isn't capture anymore, it's moving the stuff and getting it into the ground. Direct ship-to-well injection is one way around the pipeline permitting mess.
