Rotoboost, a Nordic hydrogen producer, has received Approval in Principle (AiP) from Lloyd’s Register (LR) for their Rotobox pre-combustion Carbon Capture System (CCS).
Onboard marine boats, Rotobox employs the thermocatalytic decomposition process (TCD), in which a portion of the natural gas fuel supply is transformed into hydrogen and graphite with the help of a liquid catalyst.
The TCD process generates hydrogen while collecting carbon in its solid state, hence dramatically reducing CO2 emissions, particulate matter, and methane slip. Depending on the chosen heating method, Rotobox can reduce overall carbon emissions by up to 100%. Fuel cells, combustion engines, or gas-fired boilers can all use the converted hydrogen from the CCS.
With less electrical power consumption than conventional carbon capture systems and less space needed for solid carbon storage, Rotoboost’s technology is easily scaleable to meet future emission restrictions. This enables the system and related storage to stay compact even during lengthy trips. The technology provides shipowners with another decarbonization alternative and is ideally suited to LNG carriers and other LNG-fueled vessels.
By validating Rotoboost’s CCS system as meeting LR’s goal-based and thorough prescriptive requirements, the AiP adds another significant development to the field of carbon capture technology.
