Abstract
Fossil fuels dominate the production of hydrogen and will continue to contribute in a decarbonised future. Blue hydrogen production from natural gas with carbon capture and storage technology applied is seen as the major route for natural gas in a future Hydrogen Economy. Methane leakage rate in natural gas supply chains and carbon capture rate are two critical parameters for the success of blue hydrogen. Despite this, the linked effect of the variables are difficult to identify, especially in terms of their impacts on decarbonisation metrics within the energy system. We formulate a new Combined Warming Index (CWI) measure and develop a framework for analysing the influence of methane leakage rate and carbon capture rate on blue hydrogen viability and other relevant energy system characteristics. Framework outline: • Investigate energy system scenarios within a range of methane…
