Lloyd’s Register has awarded Approval in Principle (AiP) to Norwegian hydrogen company Rotoboost for its “Rotobox” pre-combustion carbon capture system (CCS).
In a typical hydrogen application, green hydrogen is produced by passing electricity from a renewable source (wind power, solar cells) through an electrolyser, which splits water into its constituent atoms: hydrogen and oxygen. The best electrolysers can achieve efficiencies of up to 30%.
Now Rotoboost has developed a technology for converting 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 Rotoboost system uses a thermocatalytic decomposition process where part of the natural gas supply is converted into hydrogen and graphite with a liquid catalyst. The company claims that the process can reduce overall carbon emissions by up to 100% depending on the heating method.
