The US is assisting China to meet clean air standards in time for the 2008 Olympic games. For China, the Olympics are a great incentive to make strides in this area and the US has pledged to cooperate with Beijing in its efforts.
The JWG (Joint Working Group) identified 10 areas for cooperation – natural-gas technology; combined cooling, heating and power (CCHP); clean coal; hydrogen and fuel-cell vehicle demonstration; environmentally friendly buildings; urban transportation; air quality; water quality; solar photovoltaics; and a Beijing-Chicago Friendship Cities Initiative to promote local environmental activities.
There is also going to be a hydrogen park:
Gebert said a Hydrogen Park in the Olympic Village will demonstrate hydrogen technology by operating five buses using Hythane® technology – a mix of hydrogen and natural gas.
We've earlier noted China's ambitious hydrogen plans.
