Review of hydrogen source inexpensive preparation engineering

Cheap source of hydrogen is the key to the hydrogen industrialization.Now to produce hydrogen from coal,oil fossil fuels and natural gas is beginning to take shape of the industrialization process,but this does not meet the needs for sustainable development.The way to produce hydrogen from non-fossil fuels is to be opened up,one of which is electrolyzed water with large-scale hydrogen production capacity.Lowering power consumption is the key to spreading the technology.The technology of photolysis water can be derived from solar energy,and can be applied to seawater and freshwater,the resource of which is extremely rich,there fore it is a very promising method of hydrogen production.With low energy consumption,environmental protection and other advantages,biological hydrogen production technology is currently studied home and abroad.Production from waste organic wastewater is not only conducive to the improvement of the environment and recyclable energy and cost reducing,but also has a set of environmental,social and economic benefits of a new type of integrated environmental protection industries.It is a direction of the development.
