“…The first benefit relates to using hydrogen domestically to decarbonise Australia's energy use. The second focuses on Australia's huge potential for producing green hydrogen to export to markets such as Korea and Japan (Ally et al, 2015;Walsh et al, 2021;Wang et al, 2021). Respondents in the Domestic stream were provided with two figures showing domestic applications of hydrogen along with a brief description of how it can be used.…”

“…While the use of hydrogen to decarbonise energy-intensive sectors such as steel making (Venkataraman et al, 2022) and heavy transport (Ally et al, 2015) is in its infancy, households do not currently have direct access to hydrogen as a fuel or through fuel cells (Li and Taghizadeh-Hesary, 2022). However, hydrogen is beginning to be blended into existing gas pipelines and delivered to households as an important first step to decarbonising Australia's economy (Walsh et al, 2021). -Secondly, after being one of the largest exporters of coal, Australia now aims to become one of the largest hydrogen exporters in the world.…”

“…The interim findings from the Net Zero Australia report 1 also show that for Australia to export hydrogen compounds like ammonia, it is cost-competitive with other countries. Something that other developed countries, with less access to abundant resources, can also benefit from (Walsh et al, 2021). While some capital mobilisation and infrastructure challenges remain, such as the need for dedicated hydrogen transport pipelines and additional water supply, countries such as Korea, Japan and Germany have expressed an interest in entering into hydrogen purchasing agreements, and there is already increasing investment in hydrogen shipping and transport infrastructure (CSIRO, 2021;Deloitte, 2016).…”

Early research has suggested the societal acceptance of hydrogen to decarbonise our energy supply is relatively high. However, the specific aspects of hydrogen that citizens support remain unknown. To investigate public support for export and domestic applications of hydrogen, this study implemented an Australian nationally representative survey. Using a quasi-experimental design, information was provided to respondents as an intervention to test individual responses. The information included a short video, followed by images and text descriptions. The study found the combined information package increased societal support by 10% when compared to the baseline with the change in support for export applications being significantly higher compared to domestic applications. While encouraging the development of Australia’s export industry it was also found that respondents’ general support depends on their socio-economic characteristics and geographic location.

“…The likelihood that a mineral exploration project ultimately goes into production depends on a large number of social, political, economic, technical, and environmental factors (Figure 1). However, most practical applications of prospectivity modelling have tended to focus on geological favourability, rather than including the economic and/or technical constraints that are known to have a dramatic impact on the overall assessment of mineral potential (Walsh et al, 2020(Walsh et al, , 2021. The BlueCap simulator, a recent pre-scoping analytical tool deployed in Australia (Walsh et al, 2020), addressed that knowledge gap by allowing proximity to infrastructure, access to energy and water, tax schemes, and cover thickness to be considered during the mineral exploration targeting stage, focusing mineral exploration expenditures to the most geological and economically favourable areas (Figure 1).…”

Electrification of Canada’s energy and transport sectors is essential to achieve net-zero emissions by 2050 and will require a vast amount of raw materials. A large proportion of these critical raw materials are expected to be sourced from as yet undiscovered mineral deposits, which has the potential to accelerate environmental pressures on natural ecosystems. Herein we overlay new prospectivity model results for a major source of Canada’s battery minerals (i.e., magmatic Ni ± Cu ± Co ± PGE mineral systems) with five ecosystem services (i.e., freshwater resources, carbon, nature-based recreation, species at risk, climate-change refugia) and gaps in the current protected-area network to identify areas of high geological potential with lower ecological risk. New prospectivity models were trained on high-resolution geological and geophysical survey compilations using spatial cross-validation methods. The area under the curve for the receive operating characteristics (ROC) plot and the preferred gradient boosting machines model is 0.972, reducing the search space for more than 90% of deposits in the test set by 89%. Using the inflection point on the ROC plot as a threshold, we demonstrate that 16% of the most prospective model cells partially overlap with the current network of protected and other conserved areas, further reducing the search space for new critical mineral deposits. The vast majority of the remaining high prospectivity cells correspond to ecoregions with less than half of the protected areas required to meet national conservation targets. Poorly protected ecoregions with one or more of the five ecosystem services are interpreted as hotspots with the highest potential for conflicting land-use priorities in the future, including parts of southern Ontario and Québec, western Labrador, and northern Manitoba and Saskatchewan. Managing hotspots with multiple land-use priorities would necessarily involve partnerships with both Indigenous peoples whose traditional lands are affected, and other impacted communities. We suggest that prospectivity models and other machine learning methods can be used as part of natural resources management strategies to balance critical mineral development with conservation and biodiversity values.

“…Production of cleaner hydrogen will support new industries, create additional jobs across the hydrogen value chain, and grid balancing in Australia. Large-scale deployment of hydrogen projects will create supporting activities like hydrogen piping, transport, welding, and testing services (Walsh et al, 2021). A rise in demand for net zero-emissions transport solutions could potentially disrupt the existing energy value chain.…”

The hydrogen economy is on the verge of expansion across the globe. Leading economies like Japan, South Korea, China, the United States of America, Germany, and Australia are steadily pushing for greater hydrogen integration into their energy systems. Australia's thrust on the hydrogen economy becomes prominent with clear strategic actions to enhance clean technology‐based hydrogen production. The paper critically analyses Australia's strategies and policies to expand its hydrogen economy. The paper found that Australia fixed ambitious targets to increase hydrogen penetration in the domestic market and export to Japan, China, and South Korea. Australia's national hydrogen strategy emphasized creating a strong hydrogen value chain to capitalize on abundant renewable resources. This article affirms that Australia has enormous potential for cost‐competitive green hydrogen production and export. Australia's cost‐competitive green hydrogen production with modern supply chain infrastructure will offer competitive advantages over the other exporters. States/regions are trying to align their hydrogen policies and strategies along the lines of the national strategy. However, some concerns demand timely attention from the stakeholders. Australia should address multiple challenges, including a lack of investment, lower public awareness, and insufficient infrastructure to push hydrogen adoption in the domestic market. Further, Australia must utilize its strengths to take advantage of the emerging hydrogen markets in Japan, China, and South Korea.
