HEINEKEN
Rondo Energy and EDP to install a 100MWh heat battery Heat-as-a-Service solution for HEINEKEN, powered by solar on-site and renewables through the grid, and supported by the European Investment Bank and Breakthrough Energy Catalyst.

Holmes Western
This 100 MWh Rondo Heat Battery is the world’s largest industrial heat battery, delivering 24-hour steam powered entirely by off-grid solar. The first commercial system of its kind, it provides record-setting efficiency and reliability while lowering emissions and energy costs — proving a new path for large-scale, renewable industrial heat.

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.

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.

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.

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.

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.

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.
