A London-based startup has introduced a groundbreaking innovation that could make traditional drink refrigeration obsolete.
Delta H Innovations has developed the world’s first self-cooling aluminum can, dubbed the Cool Can, which promises to chill beverages at the press of a button—without any need for electricity.
How does it work?
The Cool Can looks like any regular aluminium beverage can but features a discreet power button at its base. When pressed, the button releases water into the space between the can’s double-layered aluminium walls, where it reacts with embedded proprietary salts. This reaction rapidly cools the liquid inside, reducing its temperature to around 6-7°C (42.8 – 44.6°F) within 10 minutes. A clever snowflake indicator on the can turns blue when the drink reaches its optimal chill.
Game-changer for the beverage industry
James Vyse, the Welsh founder of Delta H Innovations, acknowledges that such technology is usually developed by big corporations, not independent inventors. However, he believes Cool Can could be as transformative as Tetrapak.
Leading beverage giants like Coca-Cola and Red Bull are reportedly in talks to incorporate this technology into their packaging, which could significantly reduce the need for refrigeration, cutting both costs and carbon emissions.
Is it practical?
Early testers, including journalists from The Evening Standard, have confirmed that the Cool Can works as advertised. However, there is a trade-off—the can’s cooling mechanism reduces its capacity, meaning a 500 ml-sized Cool Can can only hold 70% of a conventional drink.
Despite this, Vyse remains optimistic. Fully recyclable and energy-efficient, the Cool Can could soon become a staple at outdoor events and festivals. Delta H Innovations aims to roll out testing at music festivals this summer, giving consumers a taste of what might be the future of chilled beverages.
