Through the implementation of Rondo’s flexible electrified solution, you can decarbonize the most hard-to-abate stages of the aluminum production process at an unparalleled cost; significantly decreasing the carbon footprint of the manufacturing process and, consequently, realizing an increased ‘green premium’ market value for the final product aluminum.
Rondo’s thermal batteries deliver a cost-effective, efficient, and robust energy solution tailored to every stage of the aluminum production chain. From continuous steam for refining, electricity for smelters, to heat for alumina calcination, Rondo provides the flexibility and reliability needed to drive decarbonization and fossil fuel replacement while optimizing performance and saving energy costs across the operations.
RHB provides high-temperature steam and hot air for diverse energy requirements.
Achieves round-trip efficiencies up to 98% while converting renewable electricity to thermal energy.
Charges during off-peak periods, storing energy to use when needed.
Can be configured for low to high-pressure steam for direct use in alumina refineries, hot gas for alumina calcination, or baseload power generation for smelters.
Rondo’s round-trip efficiency reaches up to 98%, far surpassing conventional boilers. Rapid charging over a few hours per day, paired with 24/7 discharge can significantly reduce energy costs.
Aluminum producers use natural gas to convert bauxite to aluminum via the Bayer process, a process that requires huge amounts of high-temperature heat in the form of both steam and hot gas.
According to European Aluminium, in 2022 Electricity costs represent, on average, up to 40% of European primary aluminum production costs. A sustainable, cost effective solution is a critical next step for this vertical segment.
