Australia’s opportunity: Synergies between renewable energy export and domestic energy transition in Australia
The global energy system needs to undergo a fundamental transformation to net-zero emissions by 2050 to avoid dangerous climate change. Energy system planning and optimisation have been an active research area to facilitate this great energy transition. Changlong’s PhD project involves the development of a large-scale multi-decadal capacity expansion model that can simultaneously optimise the generation, transmission, and storage systems for an orderly transition of the Australian energy system to a carbon neutral system.
The model focuses on energy sector coupling and path dependency modelling. The model applies a different modelling approach and scope to the Australian Energy Market Operator (AEMO)’s Integrated System Plan (ISP), so it could provide complementary insights into system outlook and policy development. The model has been used to explore export opportunities (in terms of hydrogen, renewable electricity via HVDC cables and green steel) for Australia in a carbon-constrained world to come.
In this seminar, Changlong will highlight the synergetic benefits between renewable energy export and domestic energy transition in Australia. In particular, Changlong will discuss the modelling findings with regard to net-zero emissions, direct electricity export to Indonesia via HVDC links, the impact of hydrogen industry on the Australian energy system, and the optimal locations of prospective hydrogen production in Australia.
Changlong is a PhD candidate at the Climate and Energy College, University of Melbourne. His PhD thesis was on “modelling Australia’s transition to a low carbon electricity system with optimised transmission networks and renewable energy exports”. Changlong is also a researcher at the Australian-German Energy Transition Hub and has been working in a bilateral scenario modelling group of 15 researchers to investigate the impact of large-scale hydrogen industry on the Australian energy system. Meanwhile, he is one of the two Australian experts, who represent Australia in a new IEA, Hydrogen Implement Agreement, Task 41: “Analysis and Modelling of Hydrogen Technologies”. His work involves developing knowledge of modelling Hydrogen in the value chain.
