More than 100 million households globally use heat pumps, which are gaining popularity as a more sustainable alternative for heating and cooling. Most heat pumps use energy-intensive compressors with harmful synthetic refrigerants.

New Hampshire-based Evari has developed a pocket-sized, oil-free turbocompressor, which the company says can be up to 50% more energy-efficient and cheaper to manufacture. Evari’s turbocompressor uses natural refrigerants, such as ammonia, carbon, hydrocarbon, water and air.

Evari’s approach “can cut gigatons of carbon in the coming years by improving efficiency, eliminating polluting refrigerants, and advancing the electrification era,” said Temple Fennell of Clean Energy Ventures, which led the seed financing.

Path to commercialization

The new capital will help Evari chart a path to commercialization. “Over the next two years, we’ll be building one-off units for customer demonstrations. In three years, we’ll be ready for low-volume production,” Evari’s Jonathan Bass told ImpactAlpha.

Evari’s turbocompressor can fill cooling and heating applications across mobility, industrial heating and aerospace engineering, Bass said. Evari has a goal to mitigate 2.5 gigatons of CO2 equivalent by 2050.
