The Australian Renewable Energy Agency (ARENA) will provide $17.2 million in funding to Mars Petcare to develop the renewable energy plant at its Wodonga manufacturing facility, featuring an Australian first concentrated solar thermal deployment.
ARENA said the project will demonstrate a pathway where using concentrated solar thermal as a heat source can support industry to reduce their emissions.
The facility will be the first in Australia to switch to 100 per cent renewable power via a mix of solar and thermal energy technologies and hydrogen.
ARENA CEO, Darren Miller, said the project aims to prove what the technology can offer Australian businesses.
“We’re excited to be working with Mars Petcare to demonstrate the potential of concentrated solar thermal as a viable option for Australian industry to generate renewable heat, making use of our abundant sunshine to provide the energy required.
“With industry currently accounting for around 44 per cent of Australia’s total emissions, we need to look at all renewable energy technology options to generate enough energy to power industry and solve this challenging piece of the puzzle.
“Concentrated solar power has been used for electricity and heat generation for decades overseas, so it’s great to see the renewed interest in it from Mars Petcare in what could be a growing trend for Australian industry in its journey to net zero.”
The promise of concentrated solar thermal as a renewable heat source lies in its smaller land requirements when compared to electric heating backed by solar photovoltaic (PV) and the ability to avoid upgrading power supply infrastructure.
ARENA hopes the project will provide a blueprint for industrial facilities looking to generate renewable energy from heat on site, where land availability constrains the use of PV.
The $39.3 million Wodonga Concentrating Solar Thermal & Thermal Energy Storage Project is set to be the first deployment of parabolic trough concentrated solar thermal technology in Australia and is the sixth largest deployment of solar heat for an industrial process, globally.
ARENA funding will support Mars to install the 18MW (thermal) concentrated solar thermal plant to provide industrial process heat to the pet food factory.
Mars Petcare Australia and New Zealand General Manager, Craig Sargeant, said investing in this technology is a significant step for Mars in Australia and globally.
“Mars would like to thank the Federal Government for its range of clean energy initiatives and is proud to be partnering with ARENA to develop Australia’s first commercial deployment of Concentrated Solar Thermal at Mars Petcare Wodonga.
“Most Australians would be familiar with Mars’s Petcare brands but what they wouldn’t know is that today’s announcement enables our Wodonga facility to become a fully decarbonised large-scale steam-based manufacturing site in Australia within the next two years.”
Mars Petcare Wodonga will use the parabolic trough technology to harness thermal energy from the sun, discharging heated water/steam mixture to a steam drum, to be directed to a series of steam accumulator tanks.
The steam accumulator tanks will provide up to 150MWh steam thermal energy storage system to provide round the clock process heating even when the sun doesn’t shine.
The project will use water as the heat transfer fluid, storage medium and energy carrier to avoid the requirement for heat exchangers and thermal oil systems commonly utilised in CSP plants.
ARENA said it has funding available for industrial energy projects through several active programs, including the $400 million Powering the Regions: Industrial Transformation Stream. For more information on existing ARENA projects or to apply for funding, visit ARENA’s funding page.
