2 Hydrogen Production Recent worldwide production of hydrogen from different sources: SourceAmountPercent (billions N cubic meters/year) 1.Natural gas24048 2.Oil15030 3.Coal9018 4.Electrolysis204 Total500100 3.

3 Hydrogen Production Electrolysis 8.

4 Hydrogen Production Indium-tin oxide = ITO (photon absorbent) Solar Energy conversion

5 Hydrogen Production Production from Methane This process is highly endothermic and will sometimes produce CO as a toxic byproduct. 2.

11 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
