Hydrogen project

Project Description

This project seeks to gain an enhanced understanding of what water is available and how it can be used in a new hydrogen economy in the Mallee region.

Themes:

• WATER USE FOR HYDROGEN
• WATER SOURCES
• SCENARIOS
  • What are some possible future scenarios in terms of water sources and demands for hydrogen production in the Mallee

Key questions included:

• WATER USE FOR HYDROGEN
  • How much water is required to produce hydrogen? Are there infrastructure considerations for the hydrogen technology?
  • How pure does the water have to be to make hydrogen? (What role does desalination or demineralization of water play?)
  • How much water does hydrogen production produce?
  • Can water be recycled in hydrogen production?

• WATER SOURCES
  • What different types of water are available in the Mallee region? (groundwater (including Artesian water), surface water, wastewater (including recycled water) and water shares (entitlement (high and low security).
  • What are the practical requirements for accessing these sources (location, supply, pumps)
  • What are the regulatory and environmental constraints to accessing water for production hydrogen? (for the different sources)
  • What are the approximate costs of accessing water (for the different sources)
  • What percentage does water make of the total cost of hydrogen production?

• SCENARIOS
  • What are some possible future scenarios in terms of water sources and demands for hydrogen production in the Mallee in 20 years’ time
  • For these scenarios, how does amount of water to make hydrogen compare to horticulture production.
  • What is the cost of water supply as a % of the total costs of hydrogen production?
  • Evaluate the different water source options for use in Hydrogen production in the Mallee?
