Power from waste project in Australia

Goal to eliminate methane leaks, carbon-free electricity

US-based 247Solar Inc. and Australia’s Advanced Energy Tech Pty Ltd (AET) announced an agreement to integrate their technologies to eliminate methane leaks from landfills by repurposing solid waste into carbon-free electricity and useful products.

The first commercial-scale system will be built at the Pyramid Hill landfill in Victoria, Australia, and operational in 2022. Energy from this new source will provide a new revenue stream for landfill owners, and enhanced repurposing will extend the operational lives of the landfills and allow landfill sites to adapt to a more sustainable operating model. The near-term addressable market is more than 1300 municipal landfills in Australia alone.

US-based 247Solar Inc. and Australia’s Advanced Energy Tech Pty Ltd (AET) announced an agreement to integrate their technologies to eliminate methane leaks from landfills by repurposing solid waste into carbon-free electricity and useful products.

“Partnering with AET to offer municipalities a new waste management system that eliminates future methane leaks and provides zero-carbon electricity is a big win for climate change solutions in Australia and the world,” said Bruce Anderson, 247Solar CEO. “Partnerships like this reinforce the 247Solar mission to bring exceptional zero-carbon energy solutions to the fight against climate change.”

AET’s waste to resource systems expand the types of materials that can be repurposed by reforming waste that otherwise would result in landfill into valuable products like engineered rock for the construction industry, biochar for agri-business, and more. Their systems operate alongside existing waste and recycling services and add value to current recycling streams by repurposing what has previously been considered problematic waste into usable products and energy.

In the combined solution, clean hot exhaust from AET’s thermal process is converted directly into zero-carbon electricity by 247Solar’s Heat2Power turbine — what the company calls the first-ever commercial turbine able to produce power directly from ambient-pressure hot air without combustion or emissions. Electricity generated in this way can be used to power industrial applications or be sold to the local grid. The turbine is manufactured under license by Capstone Green Energy of the US.

Capstone’s microturbine technology is at the heart of the pre-engineered Heat2Power solution. Two C200 microturbines are part of a renewable energy solution with no carbon or criteria pollutant emissions. The turbine’s technology is extremely low maintenance, requiring only 4 to 6 hours of maintenance a year, the company said.

247Solar, with origins at the Massachusetts Institute of Technology (MIT) and with funding support from the US Department of Energy, is commercializing multiple breakthrough inventions that aid in the world’s race towards climate change solutions. Together, the 247Solar products and solutions, and technology break the ceiling with a new Ultra-High-Temperature Solar Technology Platform. These technologies can be combined in a variety of ways with diverse applications. These applications include:

Overnight battery storage for grids with 24/7 dispatchability

24/7 dispatchable, zero-carbon electricity and heat

Converting waste heat from industrial processes, such as AET’s gasification system, to electricity without emissions

247Solar technologies are modular, scalable, factory-produced, and easily incorporated into a variety of business models and revenue streams.

About Advanced Energy Tech

Advanced Energy Tech (AET) is an Australian Engineering, Procurement, and Construction company specializing in waste-to-resources systems. The systems are comprised of innovative modular technologies from partner suppliers that are integrated and then deployed, operated, and maintained by AET at landfill and disposal sites.

AET’s systems alleviate the impacts that waste and over-reliance on natural resources are having on the environment and contribute to the remediation, improvement, and protection of the natural environment without shifting the burden to other parties.
