CEIC6714 Mini Design Proposal
Brief:
· Your team has been engaged to develop a business case for the use of locally generated green hydrogen and/or derivatives within the mining value chain in Australia.
o The derivatives you can use include ammonia and methanol, such that the costing tools for hydrogen, ammonia, and methanol can be used.
· The mining value chain is defined as including ore extraction, mineral processing, and transportation of minerals to a port for international export.
· The primary objectives of this project are:
o To evaluate the technical feasibility, the financial viability, and the environmental impact of the production of green hydrogen and derivatives in Australia, and subsequently use of this hydrogen locally within the mining value chain.
o To reduce the CO2 footprint of your mining process by at least 50% if possible, or as high as you believe is reasonable and achievable.
· More detailed information is given below.
Expectations:
You are expected to complete a report and video presentation comprising the following key project information:
· Project location.
o The mine site location will be given to each group. Mines include:
§ Boddington gold mine (Au) – Groups 1-2
§ Olympic Dam metal mine (Cu) – Groups 3-4
§ Cannington silver mine (Ag) – Groups 5-6
§ Mount Whaleback mine (Fe) – Groups 7-8
§ Murrin Murrin Mine (Ni, Co) – Groups 9-10
o You should estimate what the Scope 1 and 2 emissions are from this specific mine site
o These numbers will be needed to validate that you can reduce the emissions across the whole value chain by 50%
o Find the renewable energy generation data for your site using renewables ninja – the instructions are in the manuals for all the tools.
· Hydrogen and/or derivative end use.
o The end use must be located at the mine site(s) chosen.
o You have the option to supply hydrogen and/or derivatives to as many end use application areas within your mine site as desired.
o You should include an analysis of the expected hydrogen/derivatives required per year for this end use.
· Process:
o Detail the process narrative (using a process flow diagram), including any auxiliary/waste streams. Note that a mass and energy balance is not required.
o Determine a power plant configuration that is reasonable for the project location and in consideration of local infrastructure
· Economic analysis:
o Use the hydrogen cost tool to estimate a levelised cost of hydrogen/derivatives production over a 25-year period.
o Calculate any other project aspects not incorporated into the levelised cost. For example, the cost to replace current equipment or retrofitting.
o Justify changes to the inputs to the model that are different to the default values, if any.
o Provide commentary on the economic feasibility of the process. Is the cost reasonable compared to the current approach? What changes within the next decade could improve the techno economic feasibility?
· Environmental assessment
o Provide a judgement of the emissions reduction due to implementing your processes.
o Provide an assessment of environmental impacts such as traffic movements, power requirements, air and noise emissions, waste management and community impacts.

o Process descriptions and process flow diagrams.
o Key equipment sizing (capacity of renewable plants, electrolysers, batteries etc.) and plant layout.
o Economic assessment.
o Environmental assessment.
o Conclusion.
o Reference list.
o Appendices. Note that your inputs to the tool (with justification) and key outputs should be in the appendix.

· Video should be approximately 2-3 minutes long.
· Explain your key findings tailored towards the general public.
· Avoid technical terms or jargon.
· Avoid discussion of irrelevant sections of the report (such as MEB, plant design), and focus on key outcomes (Economics and product / market / environmental aspects)
