| contents | Certification of low emissions products is crucial to ensure that they can attract a "green premium" in international markets but need to be designed so that they do not impose undue regulatory burden or drive-up production costs. In this work, we employ energy system modelling to evaluate how different policy choices affect the cost and certified emissions of hydrogen produced by grid-connected electrolysers in Australia. As a major exporter of energy and ores, Australia has ambitions to become a 'renewable energy superpower' by providing commodities with low embedded emissions. Our analysis shows that emissions are not always accurately accounted for under the currently proposed Australian methodologies. However, imposing geographic correlation and relatively relaxed temporal correlation requirements on the use of renewable energy certificates could be sufficient to ensure minimal emissions at low cost. Our findings provide evidence to assist in the design of robust and practical certification schemes. |
