Reforming of natural gas is by far the largest source of hydrogen, accounting for around 80% of hydrogen production. When combined with carbon capture and utilisation, or storage (CCUS) low-carbon hydrogen, or ‘blue’ hydrogen is produced. In a paradigm shift away from conventional reforming processes and post-combustion CCUS, Nu:ionic, a start-up based in Atlantic Canada, has a new take on hydrogen production. Their process uses catalytic microwave reforming of methane to generate hydrogen. Methane consumption is reduced by about 30% compared to conventional reforming techniques, resulting in low cost, low carbon hydrogen.
