An Italian manufacturer has started up what it describes as the world’s largest steam-producing ...

Researchers in Italy have designed a novel carbon dioxide heat pump that can work with photovoltaic-thermal energy, a finned coil heat exchanger and a U-tube borehole heat exchanger. Their experiment ...

CO2 heat pumps represent a promising future for cooling and heating. These systems use carbon dioxide as a refrigerant, providing an energy-efficient solution that can warm your home while heating ...

Scientists led by China’s Dongguan University of Technology have proposed a novel control approach for water-to-water heat pumps that uses carbon dioxide (CO2) as refrigerant. The model-based optimal ...

Independent climate change advisors say the Scottish government needs to ramp up the rollout of heat pumps immediately.

U.S. sales of heat pumps overtook sales of gas furnaces last year. But what exactly is a heat pump, and why do some call it a key climate solution? Julia Simon of NPR's Climate Desk has this report.

Sales of super-efficient electric heat pumps are rising, now overtaking sales of gas furnaces in the U.S. But what are heat pumps? And why do some call them a key climate solution? Here are the ...
