Hydrogen Production Recent worldwide production of hydrogen from different sources: SourceAmountPercent (billions N cubic meters/year) 1.Natural gas Oil Coal Electrolysis204 Total
Hydrogen Production Electrolysis 8.
Hydrogen Production Indium-tin oxide = ITO (photon absorbent) Solar Energy conversion
Hydrogen Production Production from Methane This process is highly endothermic and will sometimes produce CO as a toxic byproduct. 2.

Conclusions Right now Hydrogen is: 1. Financially costly 2. Within itself environmentally sound but a danger to produce in large quantities 3. Difficult to produce without burning more fossil fuels 4. A good and efficient fuel for motor vehicles and well as household power needs 5. Simply another biological process made to industrial scale
