This great advantage has attracted many governments and industries around the world that aim to decrease their emissions and the number of policies and projects supporting clean hydrogen industry is increasing quickly. Yet, the implications of hydrogen industry at large scale is uncertain. In this paper, we provide an inventory of the techno-economic models that have been developed and/or can be adapted to investigate the opportunities and challenges of hydrogen as an alternative energy resource for Australia. We review 8 well-known techno-economic models and categorised them based on their characteristics including type, regional and time scale and the inclusion of gas and electricity systems. In the next step of this study, we will look into the key Characteristics related to future fuels such as inclusion (or the capacity of inclusion) of carbon accounting, and energy storage solution.
