UK retailer Tesco opened a new CO2 supermarket in Ningbo, China, featuring a CO2 cascade system manufactured by Carrier. With a series of energy reduction measures, up to 25% savings in annual electricity costs can be achieved. More and more food retailers are attracted by the benefits of R744 and are introducing CO2 refrigeration into their business in China. 

UK retailer Tesco has opened a new CO2 supermarket in the city of Ningbo. The supermarket located in Zhenhai District of Ningbo, occupying an area of 15,895 square meters, is the largest supermarket around the region. 
 
CO2 store allows for 25% reduction in total electricity use
 
In the CO2 supermarket, a series of energy saving technologies are used. The store adopts advanced Environmental Management System (EMS) and many energy reduction measures such as LED lights, and a heat reclaim system. The store captures waste heat to produce hot water to reduce fossil fuel use. Its CO2 cascade system is manufactured and equipped by Carrier. With the CO2 cascade system and other measures, the store can save up to 25% of its energy use, with an annual reduction of 9.7 million kilowatt hours in power and saving 1560,9 tons in carbon emissions.
 
So far, Tesco has equipped four stores with R744 refrigeration in China. The other three stores are in Beijing, Shanghai and Xiamen. In a workshop organised by the Chinese Association of Refrigeration and shecco this April, Mr. Wei Qian from Tesco China said: “in the near future, let’s say 3-5 years, all new Tesco stores will adopt natural refrigerants.”
 
CO2 refrigeration is increasing in the food industry of China 
 
In China, CO2 has been viewed by the industry as a viable alternative to hydrofluorocarbons (HFCs) for supermarkets. People have seen the benefits CO2 refrigeration systems could bring to supermarkets including energy savings, low HFC refrigerant charge, and lower HFC refrigerant costs. More and more international food retailers and consumer brands are introducing CO2 refrigeration to their business in China. In 2012, Nestlé installed an R744 refrigeration system at its low temperature frozen storage room in the city of Harbin. Tesco built a large distribution centre with a CO2 refrigeration system in Jiashan of Zhejiang Province. Carrefour is also introducing CO2 refrigeration to its stores in China. 
 
Local market players are also attracted by the benefits of R744 in the food industry. Recently, one of China’s largest seafood processing companies Dalian Zhangzidao Fishery Group established China’s largest CO2 cascade cold storage for its seafood processing in Dalian. The company is also planning on using a natural refrigerant systems for its next 30,000 tons low-temperature cold storage facility in China.
