Biohydrogen Production by an Artificial Enzymatic Pathway

Hydrogen will undoubtedly become the new generation clean energy carrier, although it is a secondary energy source since hydrogen must be produced from other primary energy sources such as fossil fuels, biomass, solar energy, wind energy, and nuclear energy. 
The three largest obstacles to commercializing hydrogen-drive fuel cell technology are 1)high hydrogen production prices; 2)limitations of hydrogen storage, and 3)infrastructure to deliver this fuel. 
Here we propose to produce hydrogen from renewable polysaccharides such as starch and cellulose by an artificial enzymatic pathway.  This new technology features several significant advantages:
1)   High yield and 98% energy efficiency
2)   Mild reaction conditions
3)   No external energy input needed
4)   Recycling all chemicals such as inorganic phosphate and coenzyme
5)   Low costs for producing hydrogen
6)   High storage capacity for hydrogen feedstock
7)   Easy and safe storage and distribution of sugars
This new technology will give rise to a new research and development frontier for hydrogen, and will highly likely become the basic technology for the incoming hydrogen economy.
