In the quest for a sustainable energy transition, the development of renewable energy sources and the electrification of energy consumption will play a crucial role. Projections indicate that domestic gas consumption may shrink by 40% to 90% by 2040, with certain users finding economic incentives to shift to electrified energy solutions. Practicality, personal preference, and regional considerations will influence the pace and extent of this transition.
Renewable electricity stands at the forefront as a primary solution for achieving low-emission energy. However, the emphasis here is on the potential of renewable gas as a game-changing resource. By integrating renewable gas networks with expanded electric grids, Australia can optimise its path to a net-zero future. This integrated approach could offer cost-effective solutions and enhance the sustainability of the energy system.
During the transitional phase, natural gas retains its importance, particularly for challenging applications such as high-grade industrial heat, peak power generation, and space heating, especially in colder regions. This strategic utilisation of natural gas ensures a stable and robust transition process while mitigating the impact of potential disruptions in the energy sector.
The existing gas infrastructure also serves as a valuable asset for the development of low-carbon gases, which may prove indispensable for industrial use in a net-zero future. An integrated clean energy system, combining renewable gas networks and expanded electric grids, holds significant promise, with regional and network-level considerations determining the most cost-effective approach.
