Australian project to explore potential use of wastewater in hydrogen production

In Australia, researchers need to work with and use resources from hydrogen production to increase sustainability and increase resources.

From the project, a team from Monash University in Melbourne is working with four companies in Water Research Australia: Yara Valley Water, Melbourne Water, Southeast Water and Water Corporation.

Hydrogen, described by the International Energy Agency as a “versatile energy carrier”, has a variety of applications and can be used in industries such as industry and transportation.

It can be produced in many ways. One method involves the use of electrolysis, by dividing an electric current into oxygen and hydrogen. If the electricity used in this process comes from renewable sources, such as wind or solar, some call it “green” or “renewable” hydrogen.

In a statement issued Monday, Monsh University said in a statement that the project was aimed at addressing “water shortages in the hydrogen production process”.

This is done by “developing a new approach to hydrogen production as a food through water electrolysis.”

Among those who commented on the project was Shiwang Zhang, a professor of chemical engineering at Monsh University.

“Currently, the amount of wastewater used is much higher than the amount of water needed for hydrogen production by water electrolysis,” he said.

“Most of treated water in Australia has been” discharged into local water sources or re-used for irrigation, “he said.

He said that the water treatment of these plants is very consistent and that electrolysis is a promising source of water.

The idea of ​​using waste to produce hydrogen is not unique to the project in Australia.

In March, for example, researchers at Coventry University said they were working with water company Save Trent and Organics Group on a project to “convert waste into tanks and other vehicles.”

According to a UK-based university, “Safe Trent currently eliminates wastewater in the sewage system due to its toxic properties, but this program can be converted into hydrogen.”

Most of the hydrogen today is based on fossil fuels, which are expensive to produce green hydrogen. The Australian government has said it wants to grow the hydrogen industry and produce “pure” hydrogen per kilogram ($ 1.45) per kilogram.

Earlier this month, British oil and gas company BP “Production of green hydrogen and green ammonia using renewable energy” could now be technically operational in Australia.

The Energy Major conclusion is based on the findings of a May 2020 feasibility study and is supported by the Australian Renewable Energy Agency, solar developer Lightsource bp and GHD Consulting Professional Services.

In a statement, BP described the vast territory of Western Australia as a “suitable place” for the development of renewable energy resources that could produce “green hydrogen and / or green ammonia” for domestic and foreign markets.
