The discussion above leads to the following results concerning hydrogen production and utilization in China: (1) The largest utilization of hydrogen in China occurs in ammonia synthesis. Currently, coal and coke is mainly used as the source material for hydrogen production. (2) The technologies of hydrogen production from coals and natural gas (including bygas of coal bed) are much matured. There have accumulated enough experiences in revaluation of CO_2. (3) There is lack of hydrogen in present China and hydrogen price is quite expensive, but there exists great potentiality in hydrogen production. (4) The research and development of alternative automotive fuel has been active and already created a strong basis of technology. Under the present conditions in China, this should be an important domain for hydrogen (or CO+H_2) production and utilization with coal and bygas of coal bed, and yet it has waited for how to choose a reasonable and realistic route according to the national and regional conditions. We believed this is the purpose to discuss here, today. (5) Development of proton membrane fuel cell has always undergone in China and many successful results of technology have been achieved. Obviously, it is a very important direction to utilize coal and bygas of coal bed in the coming time. How to well combine fuel cell development and application with cleaning utilization of coal and bygas of coal bed, even with well planning to use all the fossil energy, would be one of the important points to be discussed here, today.
