Enabling a Low-carbon Expo 2010 in Shanghai

Large-scale events are often a catalyst for sustainable urban development, improved infrastructure and increased investment. There is no better example than Expo 2010 in Shanghai. For the first time in the Expo’s history, the Shanghai edition was low-carbon, applying successful experiences in city development by using innovative "green" technologies in areas including building, transportation, energy supply and waste treatment. Sustainable companies like Siemens are a major driver behind this improvement.

Siemens is supplying more than 1 billion Euros worth of infrastructure for both the Expo and Shanghai. More than 40 Expo projects were built using Siemens technologies that improve energy efficiency without reducing quality or comfort. For example, Siemens technologies powered the "China Red" of the China Pavilion, not only creating a marvelous impression, but also reducing energy consumption by 50%. The Expo’s five permanent constructions featured the latest in Siemens building technology, thereby reducing energy consumption by 25% compared with conventional buildings. To ensure continuous and efficient power supply, especially during the peak summer season, Siemens installed energy-saving power distribution equipment.

In the "We Are the World" Pavilion, Siemens partnered with the Expo Bureau to bring visitors a vision of life in a low-carbon future. Visitors experienced innovative technologies, such as a facial recognition system used for easy home access, e-cars enabled by smart grids, a virtual workshop that helps achieve work-life balance, a tailored menu proposed by an intelligent home refrigerator, and remote diagnostic technologies showing easy healthcare solutions, just to name a few. Most of the technologies displayed are in the company’s R&D pipeline or are prototype applications.

About 90% of the total Expo-relevant business related to environmentally friendly products and solutions that aim to upgrade city infrastructure while bringing down carbon emissions. A highly efficient power plant using Siemens technology covers 30% of Shanghai’s energy demand, but uses more than 1 million tons less coal per year. One hundred environmentally friendly highspeed trains that use key Siemens components will ultimately transport passengers from Beijing to Shanghai in less than five hours. The terminal of the high-speed line in Shanghai serves as part of the Hongqiao Transportation Hub, where Siemens installed China’s largest parking management system.

By 2018, Siemens will supply infrastructure to more than 20 other major event host cities worldwide, including infrastructure for stable power grids, public mass transit and healthcare. Along with creating and preserving jobs, those projects will also improve visitors’ experiences and the quality of life in the cities in which they take place.

Engines Can Turn Waste into Value

Commercial customers all over the world are discovering the new ways to capture and use gas to meet energy needs through onsite power generation, all while reducing greenhouse gas emissions. One prime example is General Electric's Jenbacher gas engines.

In Australia, the Jenbacher gas engine business has contributed to several of the country's largest coal mine methane projects, including a power plant commissioned in 2008 operating on Jenbacher coal mine methane gas engines. The methane-rich gas coming from the mine is used to generate onsite power at Anglo Coal's Moranbah North mine in the state of Queensland, helping to reduce the amount of greenhouse gas that escapes into the atmosphere. Through the capture and use of mine gas, the Moranbah North project will deliver significant environmental benefits, reducing about 1.5 million tons of CO2 equivalent per year.

In Mexico, Jenbacher engines are at the heart of a newly expanded landfill gas-to-energy project, hailed by President Felipe Calderón as “a model renewable energy project” for Latin America. The 12 MW project converts gas from the Simeprode landfill near Monterrey into electricity, which is used to support the solid waste facility's operations as well as Monterrey‘s light-rail system during the day and city street lights at night.

In a sprawling commercial tomato greenhouse outside of Amsterdam, the world's first commercial 24-cylinder gas engine is in operation. The Royal Pride Holland project is made possible by two Jenbacher units, which were installed in a pilot project to demonstrate the engine's commercial viability for the horticultural industry. It highlights the increased emphasis on combined heat and power in Europe as the region increases its focus on energy efficiency.

Thousands of miles to the east, Jenbacher gas engines are at work in a far different way, using biogas created from chicken manure to generate power and heat at a large chicken farm north of Beijing.

The plant is the first of its type in China, and could pave the way for similar applications in the future. Providing 14,600 MWh of electricity per year, the project is designed to help reduce suburban electricity shortages. By using the biogas for power generation instead of coal, the new project is expected to reduce greenhouse gas emissions by about 95,000 tons of CO2 equivalent per year.
