Revolutionising Desalination with Renewable Energy: The Power of Sun and Wind

Water scarcity is a growing concern globally, and the increasing population, climate change, and urbanisation are putting immense pressure on existing water resources. Desalination, the process of removing salt and other minerals from seawater or brackish water to make it potable, has become essential to meet the growing demand for water.

However, desalination requires signi fi cant energy, and traditional production methods are not sustainable. Thus, there is a need to integrate renewable energy sources such as solar and wind power into desalination plants to make the process more sustainable, cost-effective, and environmentally friendly.

Solar and wind power are the two most popular renewable energy sources that can power desalination plants. Both are abundant, accessible, and reliable energy sources that can reduce carbon emissions and increase the sustainability of the desalination process.

Solar desalination involves using solar energy to generate electricity, which powers desalination. Solar panels are installed in the desalination plant and convert sunlight into electricity, which is used to power the desalination process. The advantage of using solar energy is that it is a clean, renewable, and abundant energy source. Solar energy can also be stored in batteries when the sun is not shining, ensuring a continuous energy supply.

Wind desalination involves using wind energy to generate electricity, which powers desalination. Wind turbines are installed in the desalination plant and convert wind energy into electricity, which is used to power the desalination process. The advantage of using wind energy is that it is also a clean, renewable, and abundant energy source. Additionally, wind energy can be stored in batteries when the wind is not

blowing, ensuring a continuous energy supply.

Integrating renewable energy sources into desalination plants can reduce carbon emissions, decrease reliance on fossil fuels, and increase the sustainability of the desalination process.

Additionally, it can reduce the cost of desalination by providing a reliable source of energy that is not subject to price fluctuations in the energy market.

Furthermore, using renewable energy in desalination plants can also enhance the resilience of water supplies to climate change. As the effects of climate change become more severe, water supplies become more vulnerable to disruption from droughts, floods, and other extreme weather events. Integrating renewable energy into desalination plants can provide a reliable and sustainable source of water that is less vulnerable to the impacts of climate change.

One example of integrating renewable energy sources into desalination plants is the new plant planned for Alkimos, Western Australia. The proposed plant will have a capacity of 100 billion litres per year, providing safe and secure drinking water to millions of Western Australians. The Water Corporation has already set aside $1.4 billion as a down payment for the plant, which is expected to be delivered in two stages, with the first stage expected by 2028.

In addition to the new desalination plant, the Water Corporation will secure up to 400 megawatts of additional renewable wind energy, allowing all three of Perth's desalination plants, including the existing ones at Kwinana and Binningup, to be powered with renewable energy. This will support the government's goal of reducing emissions by 80% below 2020 levels by 2030.

The new plant's design has been carefully considered to protect the surrounding environment and cultural heritage. A detailed Environmental Review Document is currently with the WA Environmental Protection Authority for assessment. The Water Corporation has also committed to a net zero greenhouse gas target across all operations by 2035.

In conclusion, integrating renewable energy sources such as solar and wind power into desalination plants is a promising solution to the growing water scarcity challenge. Solar and wind energy are clean, renewable, and abundant energy sources that can reduce carbon emissions and increase the sustainability of the desalination process. Moreover, renewable energy can reduce desalination costs and enhance water supply resilience to climate change. Governments, businesses, and communities must work together to invest in and promote the development of renewable energy-based desalination technologies.
