Apoligies, I didnt read your post " R-12: Again, I ask, how do you get the H2 gas from the water? I can and have done the research. How do you get the Hydrogen from the water? " correctly.Originally posted by alex_in_fl
And how do we get the power for electrolysis?
Here's some excerpts from some lit, although the PEM fuel cells seems to make a lot of $ sense intead of using straight hydrogen:
"Hydrogen is difficult to store and distribute, so it would be much more convenient if fuel cells could use fuels that are more readily available. This problem is addressed by a device called a reformer. A reformer turns hydrocarbon or alcohol fuels into hydrogen, which is then fed to the fuel cell. Unfortunately, reformers are not perfect. They generate heat and produce other gases besides hydrogen. They use various devices to try to clean up the hydrogen, but even so, the hydrogen that comes out of them is not pure, and this lowers the efficiency of the fuel cell.
Some of the more promising fuels are natural gas, propane and methanol. Many people have natural-gas lines or propane tanks at their house already, so these fuels are the most likely to be used for home fuel cells. Methanol is a liquid fuel that has similar properties to gasoline. It is just as easy to transport and distribute, so methanol may be a likely candidate to power fuel-cell cars.
"Since fuel cells convert hydrogen into electricity, the main question on everybody's mind is Where and how am I going to get the hydrogen to fuel up my fuel cell car? If auto engineers choose to store hydrogen compounds on board the vehicle, tomorrow's fuel infrastructure would look a lot like today's. Many other options are being explored to deliver hydrogen to fuel cell vehicles (FCVs).
*Centralized production and delivery. Hydrogen production and delivery services including a limited pipeline system already serve the needs of today's industrial demand.
*On-Site Production. The energy station of the future might produce hydrogen on demand from natural gas, other compounds or even water.
*Innovative Approaches. Fuel cell products that generate electrical power sometimes come with hydrogen generators called Reformers. An energy station might purchase one of these units, use the electricity for operations and tap into the reformer to produce hydrogen for vehicles.
Power from the sun.
*The ultimate solution might be solar powered hydrogen filling stations, where electricity generated by the sun (or by a windmill) is used to extract hydrogen from water. This is not as far out as it sounds. Two such stations already are operating in Southern California.
