Hydrogen has one of the highest energy/kg Hydrogen oxidation has only water as an emission Hydrogen is non toxic to humans More secure supply of energy Only sustainable source of energy distribution Hydrogen Infrastructure Issues : Hydrogen Infrastructure Issues Hydrogen bomb Hindenberg Hydrogen Infrastructure Issues : Hydrogen Infrastructure Issues Hydrogen Bomb fear We are not working in Nuclear energy range Hindenberg Fear 33 of 35 people killed resulted from jumping 2 of 35 were killed by burning from the flammable skin and diesel Fuel Fire The H2 fire burned for 60 sec (7.2MM ft3) The diesel fire burned for 10hrs. All that survived rode the ship to the ground Physical Data: Physical DataConclusions: Conclusions Hydrogen flames are no hotter than other gas flames Hydrogen is 15 times lighter than air so it disperses quickly up Hydrogen fires take place in 1/10 the time of other hydrocarbon fires Hydrogen fires are colorless and therefore have little radiant heat transfer Hydrogen is not toxic to humans Humans can stand a lot of heat…but not for very long Why Fuel Cells?: Why Fuel Cells? Hydrogen vs. gasoline for automobiles Gasoline well to wheel efficiency=~14% Fuel cell efficiency well to wheel =42% Hydrogen vs. coal/oil for make electricity Fossil Fuel to electricity=30-35% Hydrogen= 72-85% Fuel Cells are small enough to consider distributed generation Justifies Combined Heat and Power at home >90% eff.
