The Sunlands Co. technology is the only available thermal energy storage system that can maintain the high operating temperature range identified by IRENA in its recent Innovation Outlook report as essential to the commercial viability of TES

Our Technology

Advanced Processing Technologies
Chemical Free Process

Uley flake will be produced with the highest levels of purity without the use of chemicals. Our proprietary process is environmentally sustainable and entirely based on renewable energy. It combines the liberation of graphite particles through sequential concentrating and delaminating of flake with a specialised heat treatment utilising Sunlands Co. technology.

Manufacturing and the Sunlands Co. Partnership
Long Duration Energy Storage

Our joint venture with Sunlands Co. will manufacture the critical flake graphite-based storage media to be installed within Sunlands Co.’s long duration energy storage cells. These cells are ideally suited to serve the long duration energy storage market and position us squarely within one of the fastest growing energy market segments.

“There are several options that could move the dial on emissions from existing coal-fired power plants besides limiting their lifetimes. These include: retrofitting with CCUS or biomass co-firing equipment; repurposing facilities to focus on providing power system adequacy and flexibility...”
“Conventional sources of flexibility in the form of power plants and interconnections have long maintained the reliability of power systems around the world. Today thermal power plants provide the bulk of the flexibility required by many electricity systems and this remains the case to 2040... This is made possible by the retrofitting of existing thermal power plants, which helps increase ramp rates…”

TES Applications Satisfy a Range of Modern Network Requirements

Retrofitting of Existing Coal Fired Power Stations

The very high operating temperature range of Sunlands Co.’s cells enables this technology to be deployed across energy networks to satisfy the full range of network requirements. The retro-fitting of existing coal fired power stations represents one of the largest market segments for this technology, achieves massive capital cost savings in network reinforcement and accelerates the transition to an emissions free grid.
