IV. Energy Storage Solutions for Rural Applications:

Given the remote nature of rural homes, integrating energy storage solutions, such as advanced battery systems, plays a pivotal role in ensuring a continuous and reliable power supply. In areas where the flow of water might experience variations, especially during dry seasons or nighttime hours, these storage solutions act as a reservoir for electricity generated by small-scale hydroelectric generators.

Advanced battery technologies, including lithium-ion and flow batteries, empower rural communities by storing excess energy during peak production times. This stored energy can then be seamlessly released during periods of low water flow or when the demand for electricity surpasses the immediate generation capacity. By embracing energy storage, rural homes enhance the resilience of their small-scale hydroelectric systems, contributing to sustained energy access regardless of natural fluctuations or time of day. This strategic integration not only fosters energy autonomy but also ensures that rural communities have a reliable power source to meet their daily needs.

VI. 2023 Study on Farm Dams: Possible Key to Sustainable Rural Energy in Australia?

Research led by UNSW-Sydney indicates that Australia’s farm dams can be repurposed into renewable energy storage systems, providing a practical solution for variable renewables in rural areas. The study, published in Applied Energy, proposes the creation of micro-pumped hydro energy storage systems by connecting existing agricultural reservoirs. This innovative approach could offer reliable, low-carbon power options for rural communities.

As the demand for variable energy sources like wind and solar increases, storing excess energy becomes crucial for maintaining a stable power supply. Micro-pumped hydro energy storage involves storing surplus solar energy by pumping water to a high reservoir during peak production times and releasing it back to a low reservoir when more power is needed, generating electricity through a connected turbine and generator.
The research team utilised satellite imagery to identify over 30,000 potential sites across Australia from a dataset of farm dams. Using graph theory algorithms, they filtered promising sites based on capacity and slope, with each identified site capable of providing up to 2 kW of power and 30 kWh of usable energy. This amount is sufficient to support a South Australian home for 40 hours.
Unlike constructing new reservoirs, repurposing existing farm dams for micro-pumped hydro energy storage is cost-effective. The study emphasises the potential benefits for households, allowing them to increase solar usage, save on energy bills, and reduce their carbon footprint.

Comparisons with lithium-ion batteries in solar-powered irrigation systems showed that, despite lower discharge efficiency, micro-pumped hydro storage was 30% cheaper for large single cycle loads due to its high storage capacity. While the initial investment for this system is higher than batteries, the advantages include larger storage capacity and potential durability over decades.
Beyond cost savings, repurposing farm dams into micro-pumped hydro energy systems could provide reliable backup power for rural areas vulnerable to outages. Unlike batteries with limited backup time or generators dependent on fuel supply, a pumped hydro system could last for a day, offering crucial support during emergencies such as bushfires.

Although the study is promising, the researchers acknowledge some limitations that need further analysis, such as water availability fluctuations, pump scheduling, and discharge efficiency. They suggest setting up pilot sites to test and validate the performance of the system in real-world conditions, highlighting the significant potential for further development in this emerging technology.

VII. Super Pit Envisioned as Vast Pumped Hydro Reservoir for Clean Energy Storage

Renowned renewable energy engineering professor Andrew Blakers from the Australian National University leads a team that has diligently mapped potential sites for paired reservoirs across Australia, each boasting a minimum storage capacity of 2 gigawatt-hours. To put this into perspective, such reservoirs could power a small town for approximately three days.
The team’s interactive map showcases these strategic locations, some with a staggering capacity exceeding 500 gigawatt-hours. For context, the well-known Snowy 2.0 project, estimated to meet the energy needs of 3 million homes for a week, holds 350 gigawatt-hours.

Australia, based on the team’s comprehensive mapping, possesses the capacity not only to fulfil its entire energy storage requirements but to exceed them by a remarkable 300 times. Professor Blakers emphasises the strategic advantage of being discerning in choosing ideal locations for such reservoirs.
In the realm of innovative energy solutions, repurposing old mine pits emerges as a compelling prospect. The prospect of converting the Kalgoorlie Super Pit, currently a gold mine, into a pumped hydro storage dam post-gold mining operations is particularly intriguing. This site’s appeal lies in its substantial size and readily available volume.

As Australia, along with the global community, undertakes an unprecedented energy transition to mitigate the impacts of climate change, the Australian Energy Market Operator underscores energy storage as a pivotal requirement for the coming decade. A 17-fold increase in storage capacity by 2050 is imperative, with large-scale pumped hydro identified as a key strategy for grid stabilisation.

While macro-level pumped hydro systems address grid stability, micro-pumped-hydro energy storage, though not directly contributing to grid storage, holds promise in empowering rural Australians to reduce emissions and enhance local energy reliability. Dr. Gilmore, unaffiliated with Professor Blakers’ study, underscores the appeal of such systems in providing a secure and reliable power supply, particularly in regions susceptible to power outages.
