Renewable hydrogen pathways South Australia's abundant wind and solar resources are the launchpad for the state's renewable hydrogen industry. Reduced costs of solar and wind energy combined with electrolyser technology advancements have created a tipping point, where renewable hydrogen is now a growingly viable and much needed carbon-free fuel for both Australia's domestic and export markets. Renewable hydrogen technologies have considerable potential to couple primary energy sectors such as gas, electricity, and transport for the optimised supply of carbon-free energy to mining, agriculture and heavy industries domestically and overseas. Wind Export Utility scale solar PV HZ Liquefaction / Conversion plants Hydrogen can be liquefied or blended with other chemicals to create other products (for example, ammonia or methylcyclohexane). Industry and agriculture Hydrogen or ammonia have a variety of uses in several industries such as mining, farming and manufacturing. Storage The hydrogen is stored under pressure before being transported for use. Water Electrolyser An electrolyser uses electricity to separate water (H2O) into hydrogen (H2) and Oxygen (O2). If renewable energy is used to power the electrolyser, renewable or 'green' hydrogen is produced. Rooftop solar PV and battery storage 5 South Australia's Hydrogen Action Plan Government of South Australia September 2019 Transportation Pipeline Vehicles Fuel cell electric vehicles including cars, buses, trains, trucks, forklifts, motorcycles and others are powered by hydrogen. Natural gas network Hydrogen can be stored in the natural gas network, and used to lower carbon emissions. Electricity Hydrogen can be converted back to electricity by using a fuel cell or gas turbine. This can help supply the network during times of high demand. 6
