How do hydropanels work?

In Australia, the driest continent on earth, water is a precious commodity. We consume hundreds of millions of litres of bottled water every year, a habit that comes with a huge environmental cost. Enter hydropanel technology. So what is this technology all about?

What are hydropanels?

Zero Mass Water’s sustainable hydropanel solution recognises that manufacturing bottled water is an energy and water-intensive process. Most bottled water is packaged in PET, a type of plastic made from fossil fuels. If not recycled, millions of plastic bottles end up in landfill. It then takes tens of thousands of years to breakdown.

So what is Zero Mass Water’s solution? Solar panels that produce drinking water.

The company developed its “hydropanel” technology – dubbed SOURCE  – in the harsh desert climate of Arizona in the United States.

ARENA is providing Zero Mass Water with $420,000 in funding for the SOURCE Hydropanel Demonstration Project, a $871,000 pilot program that will see 150 SOURCE hydropanels installed across Australia.

Hydropanel test sites will be located in Sydney, regional New South Wales, Adelaide, Canberra, and Borroloola in the Northern Territory. Sound interesting? So how do hydropanels work?

How do hydropanels work?

Instead of filtering groundwater, the SOURCE hydropanels collect water vapour from the air, even in areas of low humidity. The SOURCE system is infrastructure-free. No wires or pipes, except for a single tube running from the panel to the tap.

Pure water produced on-site that is free of chemicals and has a reduced risk of contamination is the result. It’s also zero waste – which means no more plastic water bottles on the ground or in landfill. The pilot will mark the first use of the SOURCE technology in Australia.

ARENA CEO Mr Ivor Frischknecht said the SOURCE hydropanels were a unique way of accelerating solar PV innovation.

“Zero Mass Water’s project will create a product that offers a new application and market opportunity for solar PV in Australia. Using a combination of solar PV with solar thermal technology, SOURCE’s ability to create clean drinking water could be utilised to achieve positive solutions around water supply.”

Reducing disposable plastic bottles

Zero Mass Water estimates that each SOURCE panel would produce enough water to displace 20,000 plastic bottles over a 15-year period.

According to analysis carried out by Zero Mass Water, around 40 per cent of Australians regularly drink non-tap water. Of those, one quarter drink bottled water, a group of roughly 2.3 million consumers.

If one per cent of this group switched their water supply to SOURCE panels, Zero Mass Water estimated it would prevent the use of approximately 300 million water bottles and the release of 200,000 tonnes of CO2 into the atmosphere.

The Australian trial

The trial will role out SOURCE to 150 sites across Australia including Sydney, Adelaide, Perth as well as regional towns and remote communities.

The pilot will trial SOURCE in a variety of locations ranging from airports, community centres, offices and commercial buildings, sustainable properties and schools.

Trial locations include Adelaide Airport, Byron Bay’s popular cafe and restaurant The Farm and a Catholic secondary school in Perth.

The project could reduce the reliance on plastic bottled water. It can also provide accessible clean drinking water to rural communities with limited water or electricity access, or during droughts.

The pilot phase of the project will also incorporate a third party study to evaluate the environmental impacts of bottled water in Australia.
In an arid country like Australia, there are many sectors that could benefit from SOURCE hydropanel technology.

Buildings around the country could see SOURCE panels integrated to supply drinking water.

In agriculture, the technology could provide a reliable water supply in times of drought. Furthermore, it could provide water in remote locations with no access to potable water or electricity.

Mr Frischknecht said “The potential benefits of this technology to the environment are important,”

“This pilot project can produce reliable drought-resistant water sources to remote communities while simultaneously reducing the amount of plastic bottles that end up in landfill,” he said.

Cody Friesen, Zero Mass Water’s CEO said: “We are thrilled to partner with ARENA and demonstrate our SOURCE hydropanel technology in Australia.

“SOURCE hydropanels provide a renewable, infrastructure-free water solution to the driest inhabited continent on earth.”
