Discussions are growing in the CO2 capture, storage and utilisation industry about the best way to transport CO2 by ship, to connect capture sites with CO2 storage and e-fuel / green methanol production sites. Tanker ships, the normal option, are very expensive to build, probably requiring a 15+ year customer contract before they are built. They also require pipeline / terminal infrastructure, which may not be available. An alternative, being explored by Dr. Henrik O. Madsen, a former group president and global CEO of DNV (2006-2015), is to freeze the CO2 into pellets, and carry in conventional box containers fitted with 25cm insulation. This is enough insulation to maintain CO2 at the -80 degrees C required for CO2 to stay frozen in ambient pressure, with a boil off at 0.3 per cent per day (as measured on a test container from Århus Denmark to Reykjavik Iceland), which can be vented to the atmosphere. You can use the existing global network for box container transport, carryin the DecarbonICE container together with other containers. The container can be used for intermediate storage as well as for transport. In our webinar on March 5 we'll discuss what this can look like, and developments with Dr Madsen's project so far, "DecarbonICE". The project is supported by Danish Board of Business Development, Danish Maritime Fund, Maersk, Eimskip and TotalEnergies. among others. There will be costs of freezing the CO2, and a small amount of CO2 will gasify during transport and need to be vented.
