About Rondo Energy
We are transforming industrial decarbonization with our innovative Rondo Heat Battery technology. Rondo is deploying low-cost, zero-carbon Rondo Heat Batteries to accelerate the deployment of renewable energy and to significantly decarbonize industrial processes that are commonly thought of as "difficult-to-decarbonize". Our heat batteries charge from intermittent renewables to provide high temperature, continuous heat for customers safely, reliably, at an unprecedented 98% efficiency - and at a cost point that is lower than any other method.
Our technology is designed to replace fossil-fired boilers. By enabling industries to adopt renewable energy without costly factory changes, we are accelerating the transition to a sustainable future. With over $160 million in funding and partnerships across critical industrial sectors, Rondo is scaling rapidly to meet integral demand.
