AtmosZero raises $21 million to commercialise zero-carbon industrial steam boiler

Cleantech startup AtmosZero raised $21 million to commercialise Boiler 2.0, an electrified modular boiler that produces high-temperature steam with zero carbon emissions. With industrial steam accounting for nearly 15% of industrial energy use, the technology offers a Scope 1 decarbonisation path relevant to Indian food, beverage, and chemical manufacturers reliant on fossil-fuelled boilers.

AtmosZero raised $21 million to commercialise its solution for decarbonising industrial steam, which accounts for nearly 15% of industrial energy use and is produced mainly by burning fossil fuels. Spun out of a Colorado State University project in 2021, AtmosZero developed Boiler 2.0, a modular electrified boiler that uses heat from the air to create high-temperature steam at high efficiency with zero carbon emissions. The company says it consumes half the electricity of existing electric boilers and is a drop-in replacement for natural gas and oil boilers.

Industries that use industrial steam are directly affected, spanning food and beverage manufacturing, chemical production, district heating, and the built environment. Industrial process heat in the form of steam is responsible for over 2 gigatons of carbon dioxide each year. AtmosZero revealed a strategic partnership with New Belgium Brewing including a full-scale pilot at New Belgium's flagship facility, and established a European subsidiary, AtmosZero Europe B.V., based in Amsterdam, indicating manufacturers across Europe and the US as target adopters.

Industrial manufacturers seeking to eliminate Scope 1 boiler emissions should monitor AtmosZero's commercial pilot and European expansion as the funding advances both efforts. The investment came from US and European investors. AtmosZero was also awarded a $3.2 million grant from the US Department of Energy's Industrial Efficiency and Decarbonization Office (IEDO) to accelerate industrial-sector decarbonisation. Companies evaluating drop-in electrified boiler replacements should track the technology's commercial availability and validated efficiency claims as deployment scales.
