Tom Baxter, Senior Lecturer Chemical Engineer, Aberdeen University. As a proponent of hydrogen being key to the UK’s atmospheric decarbonisation drive, I am concerned that hydrogen receives so little press when compared with CCUS. Hydrogen-based CCUS is an improvement over CCS, but like CCS it requires more hydrocarbons to be produced to feed and fuel the process. An alternative is to produce hydrogen by seawater electrolysis using renewable energy. Electrolysis is seen as too expensive when compared with Steam Methane Reforming, but that is changing. Shell and others are investigating electrolysis as a competitive route to large scale hydrogen production.
