Calgren Renewable Fuels
This is the first commercial Rondo Heat Battery, providing long-duration energy storage at the world’s highest temperatures with industry-leading efficiency. This first-of-its-kind installation delivers heat as a service to lower the carbon intensity (CI) of fuel ethanol, paving the way for large-scale, cost-effective industrial decarbonization.

Diageo
Diageo is partnering with Rondo Energy to install RHBs at their production sites, providing low-cost, zero-carbon heat and power, and eliminating reliance on natural gas for boilers used in heating processes.

Eastman
Eastman will use a relatively new energy technology — thermal batteries — on a scale never seen before. Eastman’s choice of thermal battery technology for zero-carbon process heat, combined with efficient and high-yield molecular recycling technology, will address two global challenges at once.

Covestro
Covestro, one of the world’s leading manufacturers of high-quality polymer materials and their components, has selected Rondo to deliver clean energy services at a production facility in Northern Germany. An RHB100 will be delivering continuous steam powered by intermittent renewable energy, contributing to Covestro’s deep commitment to circularity and decarbonization.

GreenLab
GreenLab is a pioneer green and circular industrial park in Denmark, that works to demonstrate how energy waste can be reduced in industry. Rondo will build a “clean utilities core” supplying the companies in GreenLab with green heat. An RHB100 powered by renewables will generate high pressure steam to drive a CHP steam turbine generator cycle, translating intermittent electricity into baseload heat and power for multiple companies at the park.

Siam Cement Group
Southeast Asia’s first heat battery – the world’s first commercial heat battery at a cement plant – opens the path to simple, low-cost industrial decarbonization.
