A project using geothermal energy has been selected as a finalist in the Premier’s Sustainability Awards, which recognise outstanding achievements in sustainability across the state.
Rail Projects Victoria was nominated for its world-first pilot trial using geothermal technology to convert existing infrastructure foundations into renewable thermal energy. Rail Projects Victoria worked in partnership with the Metro Tunnel Project Packages: Early Works, John Holland (MTEW) and Tunnels and Stations, Cross Yarra Partnership D&C, and the University of Melbourne.
The project involved designing and installing three soldier piles – or foundation posts – to a retaining wall in State Library Station. Extensive data was then collected and analysed to discern the outcome.
The pilot investigated whether the project would work for geothermal energy production, the impacts of the engineering and staged construction requirements of concrete pouring and required steel density, and cost-effectiveness.
According to Rail Projects Victoria, the trial gave confidence for similar built environment applications in the future, showing that geothermal renewable energy holds potential to meet energy demands of the built environment.
“The trial also showcased how collaboration between government, academia, and the construction industry can lead to renewable energy innovation in real-life projects,” says Rail Projects Victoria. “The scientific results of this pilot are now published and may support dramatic change in the way we use our infrastructure – and foundations – as a thermal battery for renewable energy capture and use in the built environment.”
Now in its 20th year, the Premier’s Sustainability Awards program continues to grow and promote the efforts towards sustainability that are happening throughout Victoria across industry, business, and community.
Sustainability Victoria’s Interim CEO Matt Genever says the awards are an important opportunity to recognise the individual Victorians, community groups, councils and businesses who are making a positive impact.

“By recognising the innovative work being done in sustainability, we aim to inspire others so that together we can progress faster towards our goal of a climate-resilient, circular economy with net zero emissions,” says Genever.
The judging panel included a broad range of independent environmental experts selected for their sustainability and industry expertise.
