Amazon bets on what could be a game-changing heat pump

Amazon has signed a deal for a novel kind of rooftop heat pump that will provide all-electric heating, superefficient cooling, and cheaper energy bills at an undisclosed number of the company’s commercial buildings.

After a successful 6-month field trial at an Amazon logistics facility in hot and humid Houston, the tech behemoth signed a multiyear contract for the specially designed heat pumps with startup Transaera, based in Somerville, Massachusetts. Heat pumps are air conditioners that can work in reverse to provide emissions-free heating, too.

Amazon declined to reveal how many units it has ordered, what it’s paying, and where it would install them, but did say the heat pumps would help the company hit its target of net-zero emissions by 2040.

“At Amazon, we seek technologies that support our Climate Pledge goal,” Asad Jafry, the company’s director of global energy, sustainability, and automation, said in a statement. ​“This new collaboration supports expanding use of Transaera technology within our global network of buildings.”
