Arminius, how are these things expensive to maintain? Yes they are expensive, but the subsidies provided are huge. 30% of the cost of installing is covered, 30% in fuel subsidies up to 2016, plus there are rebates for decreased KW usage for the sites. Hydrogen is the most prevalent gas on earth, yes it requires energy to produce, but the byproduct of the fuel cell is pure clean water, not CO-2. The guys I talked to have had them on site since the beginning of 08, and have not had one issue internal to the fuel cell. They did say however that if the filling station looses power, there is a re-boot process that is time consuming. Do you know of any sites in SoCal using this stuff? I was told most of the installs on these things are back east.
