Abstract:

As we transition towards net zero, gases such as natural gas, hydrogen, biomethane, and synthetic natural gas (SNG) are expected to play an important role. In both Australia and globally, gaseous fuels are deeply integrated with industrial processes, power generation, and heating. They are also viewed as flexible energy carriers capable of supporting energy reliability, emissions reduction, and economic competitiveness. At the same time, the use of gas raises important questions for end users, particularly regarding the emissions intensity, the readiness of existing infrastructure for hydrogen integration, and the cost implications of emerging fuels. This talk will provide an overview of the role of gas in meeting future energy demand, with a particular focus on end-user impacts. Drawing on recent projects undertaken in collaboration with the Future Fuels CRC, it will highlight key findings from studies on hydrogen combustion, biomethane impurities, and methanation economics. The presentation will also explore the challenges that must be addressed to ensure gaseous fuels contribute to a low-carbon energy future in a cost-effective manner.
