A new project named decarbonICE has been launched to develop an onboard carbon capture and storage solution to cut carbon emissions from international shipping
Shipping companies including NYK, Sovcomflot, Knutsen OAS and Ardmore, and ship builders DSME and the mining company Vale, have teamed up with Denmark based Maritime Development Centre to develop the solution.
DecarbonICE is based on two new main ideas for the capture and storage part, respectively. The CO2 and other greenhouse gases (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 safely and permanently stored as liquid CO2 and CO2 hydrate.
The decarbonICE concept is intended for ship 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 contribute to atmospheric carbon reduction at a significantly lower cost than shore-based carbon capture.
The project started October 1, 2019 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 per cent,” stated the chairman of the decarbonICE project, former DNV GL president and CEO Henrik O. Madsen.
“As a leading and responsible shipping company, we have been studying many proposals for future propulsion systems and fuels to achieve the IMO 2050 target. We are very excited about the opportunity created through the decarbonICE technology, and we strongly support this as one of the possible ways to achieve the target,” said Mr. Taizo YOSHIDA, corporate officer, general manager of NYK’s Technical Group.
“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,” stated Mr. Odin KWON, CTO of DSME.
