AGRICULTURE
Water
The agricultural market has a large demand for fresh water and will benefit from lower cost fresh water. Current fresh water demand for agriculture in the Greater Darwin area could be met via our desalination using the waste heat from less than 100 MWe of electrical output (or 25 wells).
This new, cheaper source of high-quality water from the ocean could have a large positive impact on demand by stimulating extra production and/or investment in alternative high-value crops that may have previously been unviable because of water constraints. A dedicated pipeline to connect with existing agricultural supply networks may be required.
Hydrogen
Replacing diesel generators with hydrogen fuel-cell generators will reduce remote electricity generation costs by more than 50%.
Fertiliser
The global fertiliser and urea shortage is a major threat to Australian agriculture. The cost of urea alone has jumped from $500 / tonne to over $1,400 / tonne in 2022.
Our geothermal technology will produce urea fertiliser at a price lower than petroleum fertiliser production. The Darwin project can produce 5 million tonnes of urea fertiliser per annum using CO2 emitted from Darwin gas electricity generation.
