AB - Low-carbon hydrogen will play a key role in the portfolio of alternative fuels towards climate targets. However, there are gaps in determining how deploying different hydrogen colours and production pathways contributes to achieving climate goals in a jurisdiction, including the economic impact on the energy system, the wider system, and the impact on the final energy mix. This work is the first to perform a detailed analysis of the interrelation between blue hydrogen, green hydrogen (onshore and offshore produced) and other hydrogen colours using an energy system model. Results show that for scenarios where blue hydrogen and green hydrogen are not deployed, green hydrogen is not deployed, blue hydrogen is not deployed, and blue hydrogen, onshore and offshore green hydrogen are deployed, have energy system costs 0.94 %, 0.32 %, 0.06 % and −0.1 % respectively from a reference with the base hydrogen types, blue and only onshore green available. Our optimum 'Mixed Hydrogen Economy' scenario has lowest decarbonisation costs by 2050 when net-zero emissions is achieved and ensures diversity of energy supply to boost energy security. Results emphasise the hydrogen economy is most pronounced when all available and sustainable hydrogen production options are deployed. The findings contribute towards evaluating the impact of hydrogen deployment in low-emissions scenarios.
