The project aims at further developing a general framework for systems modelling and applying the framework to investigate the feasibility and sustainability of large-scale hydrogen production in Australia. Two pathways proposed in this project are to be examined: 1) hybrid plants sourcing hydrogen from fossil fuels and solar thermal energy and 2) hydrogen production network producing hydrogen from 100% renewable energy. The project involves building systems models and using these models to determine optimal operational parameters and conditions with the goal of maintaining export of high-end energy resources to Japan and other countries as well as using hydrogen domestically while minimising the environment effects of hydrogen production.Read moreRead less
