ABS has issued New Technology Qualification (NTQ) for a first-of-its-kind, pre-combustion carbon capture system based on the thermocatalytic decomposition process (TCD) from Rotoboost, a global hydrogen company based in Norway.
Rotoboost’s TCD allows for continuous hydrogen production and carbon capture onboard marine vessels. The system converts natural gas into hydrogen and solid carbon with a liquid catalyst. The resulting gas can be used for fuel cells or as a blend-in fuel for combustion engines or gas-fired boilers. The process can reduce overall carbon emissions by up to 100%, depending on the heating method.
Using hydrogen as a blend-in fuel promises to significantly reduce the methane slip from combustion engines and reduce particulate matter emissions by capturing carbon in solid form before combustion.
“Decomposing methane into hydrogen and solid carbon is an intelligent way to implement a carbon capture and storage (CCS) solution onboard gas-fueled ships. This method reduces the storage need onboard, and the solid carbon can be used in the production of fuel cells and batteries and can be recycled again and again. This technology is one that promises to accelerate the energy transition, supporting global decarbonisation goals,” says Georgios Plevrakis, ABS Vice President, Global Sustainability.
“The system can be scaled up modularly step-by-step to meet progressing emission regulations while being cost effective for ship owners compared to green fuels or conventional carbon capture systems,” says Kaisa Nikulainen, Rotoboost CEO.
