Danfoss and Cowi join forces on district heating in China

14 Jun 12 Danfoss and Cowi have teamed up for a major district heating project in China.

Increasing focus on energy efficiency has led to plans for the vast district heating project in Anshan, northeast of Beijing. Today, the city’s 1.8 million inhabitants use coal for heating. But according to China's five-year plan, Anshan is to reduce its CO2 emissions by 16% by 2015.

The agreement, which is described as worth hundreds of million Danish krone, will be signed at a ceremony tomorrow during when the Chinese president is in Copenhagen.

The Chinese government has decided to establish a heat transmission system with the aim of establishing a more stable heat supply and noticeably cleaner air for the city.

Anshan is home to the country’s largest steel factories. Danfoss and Cowi have developed a solution that will reuse the heat from the steel industry, contributing to energy optimisation while benefitting the environment.

The new heat transmission system will be fully paid for and thereby profitable just three years after being implemented, which is more than three times faster than similar projects in Scandinavia.

The Anshan project will generate up to 100 new green jobs in Danfoss and Cowi and create the basis for further expansion in both Denmark and China.

Danfoss already has major factories in China and its relationships paved the way for the project. Danfoss will develop, produce and deliver the equipment for the district heating systems, and Cowi will provide the concepts, specify the projects and divide them into smaller  solutions that secure efficient energy use.

Danfoss and Cowi both see district energy as a high-growth area.

The new heat transmission system is designed to provide Anshan with an annual CO2 reduction of 240,000 tonnes in the area, savings on expansion and maintenance of coal-fired plants, increased energy efficiency by reusing the steel factory's waste heat, increased heat supply stability and a better indoor climate for households.
