AtmosZero, which makes electric boilers for decarbonized industrial steam, has closed a $21 million Series A.

Why it matters: Many industries depend on steam to make their products, and current steam processes generate a quarter of all industrial greenhouse gas emissions.

How it works: AtmosZero, based in Fort Collins, Colorado, developed an electric boiler that extracts heat from the ambient air to produce high-temperature steam.

  • The startup last fall announced a pilot project with beer maker New Belgium Brewing.

The latest: AtmosZero began raising in October and on Jan. 31 closed the round, which was led by Engine Ventures and 2150.

  • Constellation Technology Ventures, the venture arm of power giant Constellation Energy, participated in the round, as well as existing investors Energy Impact Partners, Starlight Ventures, and AENU.
  • Engine Ventures and 2150 joined AtmosZero's board.

What's next: The startup plans to deliver more of its boiler systems to customers.

  • It also launched a European subsidiary in Amsterdam with the raise. It plans to expand its teams in Europe and in the U.S.
