pascal secures $8.5M to develop solid-state heat pumps
Pascal, a Harvard University spin-off, has successfully raised $8.5 million in funding aimed at advancing its innovative solid-state heat pump technology. The startup’s approach replaces traditional chemical refrigerants, which are known contributors to greenhouse gas emissions, with a safer solid-state alternative.
Advancing heat pump efficiency and sustainability
Heat pumps and refrigerators typically use chemical gases such as Freon or R-134a to transfer heat. Although newer refrigerants are less damaging to the ozone layer, they still pose significant greenhouse gas risks when leaked, accounting for around 2% of global emissions. With air conditioner demand projected to triple by 2050, the need for environmentally friendly cooling technologies has intensified.
Pascal’s system utilizes carbon dioxide compressed into cartridges filled with a specialized porous material. This solid-state refrigerant enables heat exchange by absorbing and releasing heat within the sealed cartridges, effectively eliminating the risk of gas leaks. The company reports that its refrigerators offer approximately 20% better energy efficiency compared to conventional models, while the material underlying the technology has endured 300,000 operational cycles, indicating robust durability.
Funding and future plans
The $8.5 million round was led by Sazze Partners and LB Investment, with participation from KDB Silicon Valley. This funding round came ahead of schedule following Pascal’s agreement with a leading multinational beverage company to pilot their technology. The startup aims to showcase its initial prototype by early 2027 and plans for a commercial rollout of refined refrigeration units by 2028.
Founded by Adam Slavney and Jinyoung Seo, who conducted the foundational research at Harvard’s Mason Group, Pascal combines expertise from mechanical engineering, chemistry, and materials science. The team operates out of Boston, seeking to offer a scalable and cost-effective solution by incorporating conventional components with their proprietary material.
Why Pascal’s innovation matters for Pakistan
As Pakistan faces rising temperatures and surging energy demands, sustainable cooling solutions like those Pascal develops could play a crucial role in reducing greenhouse gas emissions and lowering electricity consumption. The country’s growing urban population and increasing air conditioner usage underscore the urgency for energy-efficient HVAC technologies. Innovations such as Pascal’s offer promising paths to address environmental challenges while ensuring affordability and performance.
CEO Adam Slavney emphasized the reliability of their material, stating, “Our research proves the solid-state refrigerant is very robust under repeated stress,” highlighting the technology’s potential longevity and impact.
