247Solar – Hybrid-renewable energy grid for mining & local community (Australia)

The 247Solar project in Queensland, Australia, aims to deploy a hot-air-driven Brayton Cycle system to provide 100% of the electricity for a mine, its campsite, and an export jetty, while meeting 50% of a local aboriginal community's demand. The project expects to reduce the carbon footprint by 90%, lower energy costs by 25%, and create approximately 350 local jobs, supported by funding from the Queensland State Government and the Australian Federal Government (ARENA).

• The project utilizes a hot-air-driven Brayton Cycle system that operates at atmospheric pressure and avoids the use of steam, molten salts, or heat transfer oils to provide baseload clean electricity.
• Based on a Q4 2020 feasibility study, the total estimated demand across four sites is 8 MW. The system is designed to cover 100% of the electricity needs for the mine, campsite, and export jetty, and 50% of the local community's demand.
• The project is expected to achieve a 90% reduction in carbon footprint and a 25% reduction in the cost of power and heat, while creating an estimated 350 local jobs across three mining sites and the community township.
• Financial backing is provided by the Queensland State Government through a grant of up to EUR 1,600,000, a loan of up to EUR 1,600,000, and up to EUR 300,000 for local employment, alongside a loan of up to EUR 5,000,000 from the Australian Federal Government (ARENA).
