Revolutionizing Refrigeration: Barocal's Game-Changing Cooling Technology

TL;DR

• Barocal's barocaloric technology uses eco-friendly plastic crystals that cool by changing shape under pressure, potentially slashing refrigeration energy use by 2-3 times without harmful gases.
• The startup, founded by University of Cambridge expert Xavier Moya, just raised $10 million in seed funding to bring prototypes to market.
• This solid-state innovation could cut cooling emissions by up to 75%, revolutionizing fridges, air conditioners, and more amid rising global demand.

Barocal is poised to disrupt the century-old dominance of vapor compression refrigeration with a solid-state alternative that squeezes plastic crystals to chill food, drinks, and entire buildings. Early prototypes already match the performance of traditional compressors while promising massive energy savings and zero risk of climate-warming leaks.

The Barocaloric Breakthrough

At the heart of Barocal's innovation lies the barocaloric effect, a phenomenon where special organic "plastic crystals"—soft, waxy solids—undergo solid-to-solid phase transitions under pressure. These crystals, constantly in molecular motion, stop spinning when squeezed, releasing heat; when pressure is released, they absorb heat and cool rapidly. Unlike gaseous refrigerants that degrade the ozone or trap heat 1,000 times worse than CO2, these materials are non-toxic, affordable, recyclable, and leak-proof.

The technology pumps heat efficiently: water flows past the pressured crystals, carrying away warmth to a radiator, chilling the target space like a fridge interior. Research from a 2025 Science paper highlights "colossal" entropy changes in organic ionic plastic crystals (92-240 J/kg/K), with temperature shifts up to 23.7 K per kilobar—tunable for home refrigeration or air conditioning.

A Response to Exploding Cooling Demand

Global air conditioning units number 2 billion today, with projections hitting 5.5 billion by 2050, per the International Energy Agency. Heating and cooling already devour 40% of world energy, fueling emissions through power-hungry compressors and leaky refrigerants like HFCs. Barocal's solid-state system could boost efficiency 2-3 times, potentially slashing cooling-related emissions by 75%.

Founded in 2019 by Professor Xavier Moya, a University of Cambridge materials physicist, Barocal builds on 15 years of research with partners like the Polytechnic University of Catalonia. Moya's team discovered these crystals mimic refrigerant thermodynamics but without environmental pitfalls, positioning them as a viable drop-in replacement.

From Lab to Market: Funding and Milestones

Barocal hit a milestone on May 4, 2026, announcing a $10 million seed round led by World Fund, Breakthrough Energy Discovery (backed by Bill Gates), Cambridge Enterprise Ventures, and IP Group. This cash will scale prototypes that already rival fridge compressors in cooling power, using far less energy.

The company has racked up accolades: sole European finalist in the 2019 Global Cooling Prize, and winner of the $1 million TERA-Award in July 2025. Earlier European Innovation Council support underscores its promise for zero-carbon heating and cooling.

Why It Matters for the Planet and Your Wallet

Traditional systems rely on greenhouse gases prone to leaks, but Barocal eliminates that risk entirely with solids. Cheaper to produce from widely available organics, the tech could make efficient cooling ubiquitous—think fridges that sip power, ACs that don't spike bills, and data centers that stay cool sustainably. As climate pressures mount, Barocal isn't just innovative; it's essential, offering a greener path to keeping our world comfortable.
