Pascal secures $8.5M for solid-state refrigerant efficiency breakthrough

Startup Pascal has secured $8.5 million to advance solid-state refrigerant technology that could make cooling appliances significantly more efficient. According to TechCrunch, the funding round was co-led by Sazze Partners and LB Investment, with participation from KDB Silicon Valley. This capital supports the development of a new material class that addresses long-standing inefficiencies in heat pumps and refrigerators.

The risk

Current cooling technologies rely on gaseous refrigerants that pose environmental hazards and efficiency limits. Co-founder and CEO Adam Slavney noted that the industry has struggled with these trade-offs for decades. Older gases like Freon damaged the ozone layer, while newer alternatives such as R-134a are potent greenhouse gases. This cycle forces manufacturers to balance performance against environmental impact, often without clear winners.

Who is exposed

The cooling appliance industry, including manufacturers of refrigerators, air conditioners, and heat pumps, faces ongoing pressure to adopt cleaner technologies. Pascal has already secured a pilot contract with a multinational beverage company, indicating early commercial interest. The startup plans to deliver its first prototype early next year, with more polished refrigerator units scheduled for release in 2028.

Cost and compliance

The $8.5 million raise allows Pascal to move from experimental validation to prototype development. Slavney told TechCrunch that the unexpected early customer contract helped close the funding round. The company spent a year or two confirming experimental results that initially puzzled researchers. These materials work by releasing heat when compressed and absorbing it when pressure is released, similar to traditional systems but without gas emissions.

What should you do?

Monitor developments in solid-state cooling materials as they mature from lab experiments to commercial prototypes. Evaluate current cooling infrastructure for potential upgrades once solid-state options become widely available and cost-competitive. Stay informed about regulatory shifts regarding greenhouse gas emissions from refrigerants, as these may accelerate adoption of solid alternatives.

The background in plain language

Teams usually assess cooling systems based on energy efficiency and environmental safety. Check whether current refrigerants contribute to ozone depletion or global warming. Solid-state materials offer a physical alternative that cannot leak into the atmosphere. Understanding this shift helps organizations plan for future infrastructure changes. Evaluate how new materials might integrate into existing HVAC and refrigeration frameworks without requiring complete system overhauls.

What to do and how to stay safe: Pascal

• Review current refrigerant types in your facilities to identify those with high global warming potential.
• Track pilot programs for solid-state cooling to gauge real-world performance and reliability data.
• Consult with engineering teams about the feasibility of integrating solid-state materials into future projects.
• Monitor regulatory updates on refrigerant bans or restrictions that may drive mandatory technology shifts.
