Based on the results of a joint feasibility study, Norwegian engineering firm TECO 2030 and Austrian powertrain specialist AVL are preparing to pilot and test shipboard carbon capture and storage (CCS)
TECO and AVL said the CCS technology they envision could cut CO2 emissions by 30-40% per year on an "average capesize ship" with an average annual consumption of approximately 15,000 tonnes of fuel and approximately 45,000 tonnes of CO2 emissions.
TECO 2030 said the CCS technology would form part of a suite of integrated technologies, including hydrogen fuel cells, designed to work together to reduce greenhouse gas (GHG) emissions on board vessels.
TECO and AVL announced plans in February 2021 to build a hydrogen fuel cell factory in Norway that would produce fuel cells with a capacity of 1.2 GW per year. The companies are aiming to begin production in 2022.
The two engineering firms said their joint CCS technology study confirmed the viability of the process of removing and storing CO2 from vessel emissions and said they expected the technology to have wide appeal and applicability among shipowners.
"According to Clarksons Research Portal, CCS technology will be beneficial to over 80,000 vessels globally, and the CO2 emissions reduction possibilities on board are endless,” TECO 2030 chief executive Tore Enger said.
The onboard technology would also have a significant impact on the vessel’s Energy Efficiency Index (EEXI) and Carbon Intensity Index (CII), according to the companies.
TECO and AVL cited the 2015 Paris Agreement that seeks to limit the global average temperature rise from GHG emissions to below 1.5°C in their announcement of plans to pursue CCS technology for use on board seagoing vessels.
"According to the Paris Agreement, global greenhouse gas emissions need to be cut in half to stay below the global warming limit of 2°C. If left unregulated, international maritime transport is expected to be responsible for 17% of global greenhouse gas emissions by 2050 according to Cames et al (2015). Although shipping is by far the most carbon-efficient mode of commercial transport, greenhouse gas emissions from shipping are estimated to be about 3% of total global emissions today and predicted to increase rapidly towards 2050, if no actions are made," the TECO statement said.
The carbon capture and storage technology will be included as part of the TECO 2030 Future Funnel exhaust gas scrubbers. TECO says its system "is designed to comply with existing sulphur oxide emissions regulations and ready to adapt for future regulations such as particulate matter, nitrogen oxides, black carbon and CO2".
