The Role of Integration of Hybrid Microgrids in Decarbonising Copper Deposits Mining in Australia

This research offers an innovative perspective on decarbonising copper deposits mining in Australia through renewable microgrids. The study bridges geological exploration and renewable energy, analysing the distribution, depth, and ore grade of copper deposits and their influence on microgrid design and economics. Simulations using HOMER reveal that hybrid microgrids that have around 80% renewable penetration, harnessing solar, wind, and storage technologies, can significantly lower the Levelised Cost of Electricity (LCOE), reduce emissions, and enhance energy reliability in mining operations. The findings highlight hybrid microgrids with high renewable penetration have significant potential to contribute to sustainable mining practices, though economic feasibility varies, influenced by policy, financing, and market factors. The study calls for integrated strategies encompassing policy support, innovative financing, and stakeholder engagement to realise renewable energy’s full potential in the mining sector.
