# Solid-State Cooling Materials Pascal Packs CO₂ Into a Sponge-Like Material to Cool Efficiently By Adam Harrie | Written with AI assistance | Published 2026-10-22 | Tech Source: Trend Hunter, https://www.trendhunter.com/trends/solid-state-cooling-materials References: [techcrunch](https://techcrunch.com/2026/10/21/heat-pump-tech-is-170-years-old-pascal-thinks-its-time-for-an-update)  Pascal is updating heat pump and refrigerator hardware with a solid-state material that can make systems about 20% more efficient than existing models. Its cartridges compress carbon dioxide into a porous, sponge-like material, which moves heat without relying on the refrigerant approach used in conventional systems. Two cartridges run at a time, with one pulling heat from inside the unit while the other sends it outward. The material has been cycled up to 300,000 times, and the system does not require the high pressures that other solid-state refrigerants can need. That durability turns a lab material into something closer to a working appliance component. A pilot with a multinational beverage company and a prototype due early next year put the technology on a path toward real deployments. If Pascal can keep the system efficient and affordable, it could make lower-climate-impact refrigeration easier to build into mainstream equipment.
