increases in the efficiency of electrolysers and future reductions in the unit cost. A full-scale offtake of char or carbon black co-produced in the pyrolysis process will invariably reduce the cost of turquoise hydrogen. Progress with research on reactor design, modularisation, catalyst development, and process control will lead to improvements in process reliability with a consequential reduction in the cost of hydrogen. Methane pyrolysis is an important emerging technology that presents an economically attractive hydrogen production process with

zero CO₂ emissions. When bio-methane is used as the feedstock, it can result in a negative carbon intensity (Monolith hydrogen, 2023). Given the forecast future demand for hydrogen, it should be seen as complementary to blue and green hydrogen production and an important contributor in building the hydrogen economy.
