Affordable renewable hydrogen opens up a world of manufacturing possibilities.
There are many ways to acquire hydrogen, but green hydrogen is the only one that uses clean technology. An electrochemical device known as a hydrogen electrolyser uses renewable electricity to split water into hydrogen and oxygen in a process called electrolysis. Hydrogen is produced in this process and can be used to store energy.
Green hydrogen is a versatile energy carrier and feedstock that has the potential to transform and decarbonise many industries. Uses include: industrial feedstock, some industrial heat processes, storage for exporting renewable energy, shipping and other forms of large scale transportation, and electricity generation for rare periods of extended low sun and wind.
Producing and utilising green hydrogen for energy requires a substantial input of renewable energy, at least three times more than directly using renewable energy as electricity. Additionally, electrolysis demands a considerable volume of clean water, approximately nine litres or more per kilogram of hydrogen generated.
Transfering hydrogen is expensive and requires purpose built technology, which is the reason we advocate for green hydrogen production in Clean Industry Hubs, where it can be used directly. Our Electrifying Industry report (2018) details the important role of green hydrogen for some industrial processes.
Australian Renewable Energy Hub
The Australian Renewable Energy Hub will help decarbonise mining in the Pilbara region, providing huge-scale clean energy for local customers, and domestic and exportable green hydrogen. It has the potential to abate 3% (17Mt CO2e) of Australia's annual emissions.
Bell Bay Powerfuels Project
The Bell Bay Powerfuels Project will use renewable energy to produce green hydrogen and methanol via electrolysis of water. It is estimated that this project will abate 135,000t CO2e annually and harness 100MW of renewable energy.
Central Queensland Hydrogen (CQ-H2)
The CQ-H2 project is Queensland's largest renewable hydrogen initiative, involving the creation of a Hydrogen Production Facility and a Hydrogen Liquefaction Facility. It aims to export renewable hydrogen to Japan and Singapore and cater to domestic customers.
Central Queensland Power
This joint venture is driving the decarbonisation of heavy industry in Gladstone and the wider Central Queensland region. Energy Estate and RES are developing a portfolio of wind, solar and BESS projects with a capacity of over 2GW.
Desert Bloom Hydrogen
Desert Bloom produces green hydrogen in arid conditions. The project utilises abundant solar power to generate water, heat, electricity and hydrogen. The project has the potential to produce 410,000 tonnes of green hydrogen per annum, with no ground-based water supply.
Edify Green Hydrogen Lansdown
There is a growing need for green hydrogen domestically and across the world. Edify Energy will develop and operate a green hydrogen production plant of up to 1 GW, as well as a behind-the-meter solar photovoltaic and battery storage facility.
Endua generates green hydrogen and storage technologies for off-grid and diesel energy users to become self-sustaining and meet decarbonisation commitments. This way, renewable energy is created, stored as hydrogen, and used as electricity.
Frontier Energy is one of the first low cost green hydrogen projects in Australia. Existing water sources and surrounding infrastructure removed the need for capital intensive infrastructure, and allowed for excess solar to be sold via the main grid.
Green Energy Manufacturing (GEM) Centre
Powered by renewable energy, the GEM project intends to create a pollution-free manufacturing hub. Their objective is to produce more than 200,000 tonnes of green hydrogen annually, with a plan to increase to 15Mt CO2e annually by 2030.
The H2-Hub Gladstone is an industrial-scale green hydrogen and ammonia production complex. Powered by renewable energy, it will feature up to 3GW of electrolysis capacity and produce up to 5,000t of green ammonia per day.
The HyNQ Clean Energy Project is a green hydrogen, freshwater and renewable electricity production project at Abbot Point, North Queensland. The project will dramatically reduce the cost of green hydrogen and support local green jobs in the Bowen Basin.
Hysata has developed an electrolyser achieving 95% system efficiency (41.5kWh/kg). Hysata's efficiency, low capex due to simple bill of materials, and modular design for low installed cost will produce the lowest levelised cost of hydrogen. Backed by global investors, Hysata is moving rapidly towards multi-gigawatt scale production.
Infinite Green Energy
Infinite Green Energy will produce green hydrogen using water, solar and wind energy. Located within a couple of hours of Kwinana, the project is expected to deliver first gas in early 2024, making it one of the first true Zero Carbon Hydrogen producers in Australia.
