Conclusions Summary of Results and Suggestions for Future Analysis

8 Conclusions Summary of Results and Suggestions for Future Analysis 

A summary of levelized H2 pump prices, system capital investments, and levelized PV electricity prices are presented in Figs. 8-11 A summary of results for first gen eration (Year 1 Year 30) H2 production are as follows. The levelized H2 pump price, which does not include fuel use taxes, ranges from 6.48- 5.53/kg for 10% and 14% efficient PV modules respectively. With fuel tax, the H2 pump price is 7.47 6.52/kg, which is comparable to high-end 2005-2006 U.S. gasoline prices when the H2 is for FCVs with a fuel economy 2.2-times greater than conventional ICE ve hides. 

The capital investment for a PV electrolytic H2 system to support one million FCVs ranges from 12.4 billion for systems using 10% efficient PV modules to 10.4 billion for systems using 14% efficient PV modules. The PV power plant accounts for 59-51% of total H2 system capital investments. The levelized PV electricity price ranges from 0.064/kWh to 0.047/kWh for 10% and 14% efficient PV modules respectively. 

Hydrogen pump prices for second generation, Year 31-Year 60, electrolytic H2 production are reduced to 3.90- 3.40/kg for 10% to 14% efficient PV modules respectively in the case of a thirty-year PV module operating life and to 3.06- 2.73/kg for 10% to 14% efficient PV modules respectively in the case of a sixty-year PV module operating life. A summary of H2 pump prices is presented in Fig. 10.
