AtmosZero makes modular electrified boilers that generate decarbonized steam for industrial processes. The boilers convert electricity and ambient heat into steam, serving as a drop-in replacement for traditional fossil-fuel boilers and can be deployed in a plug-and-play, scalable way with optional leasing and maintenance. Compared with others, AtmosZero focuses on a straightforward path to decarbonization by offering a fossil-free, plug-and-play steam solution that fits existing plants with minimal changes. Its goal is to help heavy industries cut carbon emissions and achieve climate targets by providing practical, cost-effective zero-emission steam.

Existing investors Engine Ventures, Constellation Technology Ventures, and Energy Impact Partners also participated. The Colorado-based company develops electrified boiler systems designed to replace or augment conventional boilers in industrial facilities. Its Boiler 2.0 platform aims to provide a standardised product that integrates into existing infrastructure across food and beverage, chemicals, and pulp and paper industries. The investment from MHI, a global industrial equipment manufacturer, supports AtmosZero's commercialisation strategy as the industrial boiler market is projected to reach $24 billion in annual sales over the next five to ten years. The company recently partnered with R.F. MacDonald Co. to expand channel access.
AtmosZero, a Loveland, Colorado-based startup, has raised $28.5 million to commercialise electric heat pump technology that replaces fossil-fuelled industrial boilers. Founded in 2022, the company is developing an electrified steam system for industries including food and beverage, pharmaceuticals and chemicals. The company's first pilot installation began operating in May 2025 at New Belgium Brewing in Fort Collins. Investors include Energy Impact Partners, Engine Ventures, 2150, Constellation Technology Ventures, Starlight Ventures and AENU. AtmosZero's system uses electricity to power high-temperature heat pumps that generate steam at industrial temperatures up to 300 degrees Fahrenheit without on-site emissions. The company also received $1.8 million from the Colorado Energy Office and up to $24.3 million in federal tax credits. Volume deliveries are planned for 2027.

Governor Kathy Hochul today announced the selection of a winner of the Empire Technology Prize competition to advance building technologies for low carbon heating system retrofits and save energy and costs in tall commercial and multifamily buildings in New York State.
AtmosZero, in partnership with Colorado State University, seeks to develop a modular high-temperature heat pump system with the potential to significantly reduce carbon emissions from on-site heat generation in the U.S. industrial sector. Approximately 75% of all on-site energy consumption in the U.S. manufacturing sector is used to generate heat, which means industrial process heat must be decarbonized to substantially reduce U.S. emissions.
