Targeting 20,000 tonnes per annum first phase, 410,000 tonnes per annum at full scale
Northern Territory, Australia
At full scale, the project is a 10 Gigawatt (GW) modular large-scale, stand-alone, off-grid system that would produce approximately 410,000 tonnes of hydrogen per annum, using renewable energy and its own source of atmospheric water.
The project would be developed in stages with the first stage targeted to produce 20,000 tonnes of hydrogen per annum.
Over the life of the project, it is anticipated that nearly 600,000,000 tonnes of carbon offsets would be produced.
The project would employ innovative techniques to generate renewable hydrogen without requiring access to a ground-based water source or the electricity grid, through an integrated water maker that extracts water from the atmosphere and its own electricity supply.
The project consists of a series of modular (and portable) 2MW Hydrogen Production Units (HPUs), with each HPU comprising:
- a photovoltaic (PV) solar system;
- a concentrated parabolic trough (CPT) solar thermal heater;
- a water producing unit (WPU); and
- an electrolyser.
At full scale, the project could comprise 4,000 HPUs at a total capital cost in excess of US$10 billion.
Each HPU would comprise all the components required to generate water, heat, electricity and hydrogen. Each HPU is a discrete unit that can operate independently of the other HPUs. The HPUs can be co-located or can be located separately.
The modular nature of the HPUs offers operational flexibility and individual HPUs can have their scale increased if there are efficiencies in doing so.
The project is being designed to provide feedstock to produce renewables-based aviation fuels, ammonia and urea for domestic and export markets.
Commercial negotiations are underway to finalise offtake arrangements following execution of a Memorandum of Understanding (MoU) with Territory Generation (the Northern Territory owned electricity corporation). A Joint Development Agreement has been entered into with Osaka Gas.
Major Project Status was granted by the Northern Territory Government in December 2021.
The project proponent has advised that a financial commitment for the overall development, construction and operation of Stage 1 of the project has been secured – subject to successful completion of technical and commercial milestones and a positive Final Investment Decision.
Further detailed information on the project and the water-from-air technology can be found at the Aqua Aerem Desert Bloom Hydrogen Project and related webpages.
