The industrial appliances of hydrogen in China

In Xi'an Jiaotong University, several research are carried on in the field of hydrogen utilization, such as "Study on the Hydrogen combustion Power Cycle", "Utilization of Hydrogen in Space Technology", "Study on Hydrogen Combustion Flow Field and Performance Evaluation of Hydrogen Flame". A catalytic hydrogen combustion appliance is arranged in design office, intended to assure itself of practical application for civil use in near future.

Professor Yu Yiqin of Hebei College of Technology, Tianjin has devoted his study to different kinds of theoretical cycle system using hydrogen gas combustion turbine in combination with the steam turbine . Because of its full utilization of how temperature energy in liwuid hydrogen, the efficidncy of the combined cycle and its power output are are significantly enhanced.

A practical running test on bus by injecting 5% (by weight) of hydrogen to gasoline combustor was carried out in Tianjin University under the instruction of professors Shi Shaoxi and Li Housheng with little alteration of the original gasoline engine. The primary result revealed a saving of about 34% of gasoline fuel and of overall heat efficiency by approximately 15%. It is planned to use the by-product hydrogen from a water electrolysis plant as the substitute of gasoline to run the bus route from Tianjin to Tanggu where the exhaust hydrogen is available.

It is well known that there are three kinds of renewable primary energy, namely nuclear fusion energy, various renewable energy based on solar energy resources and low cost hydropower, which can afford to supply secondary energy to be stored in the form of hydrogen for further application in different respects.

If human beings are looking for the future of better livelihood and if people on the earth are quite aware of the threatening of human existence in the world, the emergence of hydrogen system has to draw the global attention not only from politic officers, but also the scientific circles and individual persons as well.
