The former head of DNV GL is leading a new maritime carbon capture and storage initiative. Henrik Madsen, who was CEO at the class society from 2006 to 2015, is the chairman of the new decarbonICE project, developed by Denmark-based Maritime Development Center and a host of top shipping names.
Nippon Yusen Kaisha (NYK), Sovcomflot, Knutsen and Ardmore, shipbuilder DSME and the mining company Vale have teamed up to develop a groundbreaking onboard carbon capture and storage solution.
DecarbonICE is based on two new main ideas for the capture and storage part, respectively. The CO2 and other GHGs in the ship exhaust are captured onboard in a cryogenic process and turned into dry ice. Proven offshore technology is then applied during normal ship operations to transport the dry ice into the seafloor sediments. Here the CO2 will be permanently stored as liquid CO2 and CO2 hydrate.
The decarbonICE concept is intended for newbuildings, but also for retrofitting on existing ships.
“In combination with future carbon neutral fuels like biofuels and electro fuels, the decarbonICE technology can create carbon negative shipping and thus contribute to atmospheric carbon reduction at a significantly lower cost than shore-based carbon capture,” the new project claimed in a release today.
The project started last month and will run through 2020. The aim is to prepare a feasibility study and to initiate the IMO approval process for the technology.
“While we support a final goal of availability of zero carbon or carbon neutral fuels, we believe that a bridging carbon free solution is needed, which can utilise existing assets in terms of ships, propulsion systems and fuels. The decarbonICE project is intended to offer exactly that, and at a predicted low energy penalty well below 10%,” said Madsen.
“The maritime industry seems to be overlooking that onboard carbon capture with subsequent storage at appropriate sites may also qualify as a carbon-free solution. At DSME we are following several Korean research groups studying the behaviour of CO2 injected into seabed sediments. The success of the decarbonICE project will also depend on how the required power can be minimised for the cryogenic cooling process,” said Odin Kwon, CTO at Korean yard, DSME.
