Zero2Cool

Zero2Cool is a London-based company that has developed patented technology for delivering decarbonized cooling solutions at zero fuel cost and zero carbon impact. The company's core offering is an absorption chiller system that utilizes waste heat from engines or generators to power air conditioning and refrigeration processes. This innovative approach allows Zero2Cool to provide cooling for buildings, refrigerated storage, and transport applications without additional fuel consumption or carbon emissions.

The company's absorption chillers are designed to work with various power sources, including diesel gensets, gas turbines, hydrogen generators, and combined cooling, heat, and power (CCHP) systems. By directly using exhaust heat to drive the cooling process, Zero2Cool's units offer significant reductions in operating costs with minimal capital expenditure. The technology is compatible with both static and mobile applications, making it suitable for diverse industries and environments.

Zero2Cool's absorption chillers use environmentally friendly refrigerants like ammonia, which has a Global Warming Potential (GWP) of zero, in contrast to conventional vapor compression systems that rely on high-GWP refrigerants. The company's engineers have developed a novel system that improves the efficiency of heat transfer and recovery within the absorption chilling process, enabling the use of waste heat from smaller generators or engines as a direct heat source.

In addition to stationary applications, Zero2Cool has designed a unit specifically for refrigerated transport. Their 7 kW truck/trailer-mounted unit can provide refrigeration for a 40-foot container using only the heat from the truck engine's exhaust. This unit weighs less than half of a conventional truck cooling unit and eliminates the need for additional fuel consumption for refrigeration purposes.
