Shanghai World Expo series 10: Zero carbon emissions at Expo park

This looks like an ordinary SUV for police use. But it is by no means ordinary. It is a zero-emissions Fuel Cell car, which eats hydrogen and discharges water. Because when hydrogen combines with oxygen, it produces what we call H2O.. This revolutionary innovation will be introduced to visitors at the 2010 world expo.

Raymond Bierzynski, VP engineering of GM Asia Pacific, said, We want to showcase what could be at the high-end of technology, which is zero emission, which our fuel cell system.

No petrol required, it can run for about 320 km at one fill-up of hydrogen. The next generation of vehicle technologies are not like conventional petrol or diesel power vehicles. They are quieter, no noise. In case of fuel cell, zero emission. The only thing from the tail pipe is water, because the fuel cell operates on the principle of combining hydrogen with oxygen.

If you think Fuel Cell cars are toooo expensive, you could also jump into some more affordable GREEN vehicles at the expo site, such as Hybrid Vehicles. These cars run by a combination of gasoline and electric power, therefore saving up to 50% on fuel. Or if that doesn't suit your fancy you could hop into an electric vehicle, they are fully powered by electricity.

Wu Chengjian, technical office of SH World Expo Coordination Bureau,said, "Our target for the expo park is "zero emissions". Therefore, we'll use a large number of new-energy vehicles, including electric vehicles, super-capacitor vehicles, hybrid vehicles, and even fuel cell vehicles. Large-scale application of these green vehicles will still have technical obstacles, such as cost and hydrogen stations. But it's feasible to use them in a situation like the expo park."

The 2010 expo park will serve as a demonstration for the transportation revolution, boasting more than 1000 zero-emission vehicles. The Expo park also have Green Houses, like this one: the EcoPlaza. Located in the former Nanshi Power Plant, EcoPlaza is a four-story building that covers a construction area of 3,000 square meters. It is one of the expo's four pilot housing projects, advocating saving energy and environmental protection, in which wind is a crucial natural resource.

Another highlight of EcoPlaza is the Sewage Water Utilization System, which would be positively affected in a city abundant in rain like Shanghai.

EcoPlaza desinger Yang Ming said, "EcoPlaza has roof gardens so that we will be able to collect the rain from the roof. On the ground, there is a eco-pool, also collecting rain.

After being processed, the water can be reused to water plants,to flush toilets and to wash underground garages and streets.

In fact, we can even purify the water into drinkable water.

We will demonstrate that fish can live in the toilet."

The Shanghai World Expo Coordination Bureau is working with the United Nations Environment Programme to develop Green Guidelines for the expo. The guidelines will address planning, operation, construction and post-usage. Climate change is a global hot topic, so experts will promote the concept of "low carbon". They will carefully study the balance of materials and calculate carbon quantity. Then they will
