Hydrogen offers diverse applications as an energy carrier and chemical feedstock and has great potential to support decarbonisation of the world’s energy and industrial sectors. Because of this, there is a growing global demand for renewable and low-emissions hydrogen. Renewable hydrogen is defined as hydrogen produced using energy from renewable energy sources. One pathway for producing renewable hydrogen is shown below. O2 Oxygen H2O Water H H 2 H2 Electrolysis Renewable hydrogen Renewable electricity Icons courtesy of and adapted from www.flaticon.com

Western Australia has many attributes that provide a comparative advantage for the production, use and export of renewable hydrogen, including: 1. Renewable energy resources 2. Land Western Australia is home to high-intensity With an area of 2.5 million km2 (one-third of renewable energy resources. Western the Australian continent), low intensity land Australia’s solar is amongst the highest use combined with low population density, irradiance in the world and, due to being Western Australia is well placed to develop on the western edge of the continent, it has large-scale renewable energy generation. 3. Existing infrastructure excellent wind resources. Western Australia has world-class industrial and export infrastructure that can accommodate the development of the hydrogen industry.

16 WESTERN AUSTRALIAN RENEWABLE HYDROGEN STRATEGY Western Australian Renewable Hydrogen Strategy 4. Strong existing industry presence 6. Access to markets Because of Western Australia’s established Another comparative advantage for LNG industry and its ability to develop Western Australia is its geographical collaborative and globally competitive proximity to Asia and its long-term presence supply chains, many of the world’s largest in these markets. There is potential to oil and gas companies have a local further strengthen Western Australia’s presence. Several major companies have strong partnerships with Japan and South expressed intentions to develop hydrogen Korea which are key partners in the growing projects in regional Western Australia. market for renewable hydrogen. This 5. Skilled workforce industry also presents opportunities for technology partnerships in Asia and Europe. Western Australia retains a technically skilled workforce with expertise across the energy sector and relevant research capabilities amongst various institutions. A skilled workforce will be essential to build a local hydrogen industry. WESTERN AUSTRALIAN RENEWABLE HYDROGEN STRATEGY 17 Vision, Mission and Goals Vision Western Australia will be a significant producer, exporter and user of renewable hydrogen. Mission Western Australia will develop industry and markets to be a major exporter of renewable hydrogen. To facilitate the export of renewable hydrogen, Western Australia will develop domestic production capabilities and applications of renewable hydrogen, improving the State’s hydrogen industry expertise, contributing to global decarbonisation and decarbonising the State’s economy. It will also contribute to improving air quality across the State. Goals By 2022 By 2030 • A project is approved to export renewable • Western Australia’s market share in global hydrogen from Western Australia. hydrogen exports is similar to its share in • Renewable hydrogen is being used in one LNG today. remote location in Western Australia. • Western Australia’s gas pipelines and networks • Renewable hydrogen is distributed in a contain up to 10% renewable hydrogen blend.

18 WESTERN AUSTRALIAN RENEWABLE HYDROGEN STRATEGY Western Australian Renewable Hydrogen Strategy The Asian Renewable Energy Hub is being developed by a consortium consisting of InterContinental Energy, CWP Energy Asia, Vestas and Macquarie Group. The proposed project consists of 11 gigawatts of renewable generation to provide power to Pilbara energy users and produce renewable hydrogen for export. The scale of the project has the potential to create new supply chains to reduce costs and provide significant new employment opportunities as well as diversify and grow the Pilbara economy. WESTERN AUSTRALIAN, RENEWABLE HYDROGEN STRATEGY 19 Strategic Focus Areas The Western Australian Renewable Hydrogen Council and techno-economic analysis by CSIRO has identified four Strategic Focus Areas for investment in Western Australia: 1. 2. Export Remote applications 3. 4. Hydrogen blending in Transport natural gas networks While these strategic areas will be a focus because of their link to Western Australia’s particular comparative advantages, the role that renewable hydrogen could play in stabilising the electricity network and in decarbonising industry is also acknowledged.

Export The global market for renewable hydrogen is expected to grow significantly over the coming decades. Western Australia is well placed to capture a significant share of this market due to its excellent renewable energy resources, skilled oil and gas workforce, proximity to Asia, and export infrastructure. In 2018, Western Australia was the second Inter-governmental relationships can also be largest exporter of LNG in the world and has further developed to firm international demand established a strong reputation internationally as for renewable hydrogen exports and give industry a capable and reliable partner. The global market confidence to form partnerships and invest in the for renewable hydrogen is expanding, presenting required infrastructure. an important economic opportunity for Western Financial support may be required until hydrogen Australia and for the transition of its industries to export pathways are demonstrated to be a lower carbon future. technically and commercially viable.

As there is a need to build scale and lower costs, Woodside is focussed on carbon-neutral hydrogen production from natural gas and renewable hydrogen production from electrolysis. Woodside has invested in the Hydrogen Energy Network consortium that plans to build and operate hydrogen refuelling stations in South Korea. WESTERN AUSTRALIAN RENEWABLE HYDROGEN STRATEGY 23 2. Remote applications Renewable hydrogen can reduce reliance on diesel for remotely located industries and communities. An advantage of hydrogen for remote applications Given the challenges involved in reducing is that there are potentially multiple end uses for emissions from heavy vehicles in mining, the the hydrogen produced. For example, renewable Western Australian Government will facilitate hydrogen could be used in fuel cells to power fixed discussions with industry to develop pathways and mobile plants, mining vehicles, combusted for and goals for reduced diesel consumption. heat, and potentially as a feedstock for industrial The Western Australian Government will processes. ensure all relevant State Government agencies Hydrogen can also be used as an alternative to support the renewable hydrogen vision to assist battery energy storage to provide dispatchable proponents in seeking approvals and permits. power and, in conjunction with batteries, to provide long term storage. If the expected reductions in the cost of hydrogen and fuel cells can be achieved, renewable hydrogen based power systems could become commercially competitive with diesel generation before 2025. Hybrid systems using a combination of renewable energy, batteries, hydrogen for seasonal storage and back-up diesel may be a pathway to more competitive supply of power in remote areas.

Hydrogen blending in natural gas networks Blending low concentrations of hydrogen into natural gas networks provides an opportunity to partially decarbonise Western Australia’s gas sector. Western Australia has a vast gas reticulation Electrolysers also have potential to provide network and a unique customer base. Blending security and reliability services to the electricity up to 10% renewable hydrogen into the natural grid by absorbing surplus variable renewable gas network could reduce the emissions energy generation or rapidly decreasing their intensity of gas combustion by up to 13%.
