Hydrogen Policy Described
Mandate the CAA CFFP program nationwide
Mandate the CPP nationwide
Tax incentives for auto companies to: develop HICE vehicles, engage in R & D partnerships, and establish a H2 infrastructure
Problems H2 policy should address:
Consumer access to a H2/ LH2 infrastructure (centralized or decentralized)
Government investment into HICE vehicle development
Government funding for H2 production
Establishment of uniform safety rules for H2 production, storage, and handling
Foreign Oil Dependence
Imported oil comprises 55% of U.S. consumption
Transportation comprises 2/3 of 20 million bbl/day in U.S.
H2 vehicles would reduce consumption by 11 million bbl/day by 2040 (EU plans 20% by 2020)
How HICEs Work
2H2+02= 2H20 + heat
H behaves like octane
Compressed H2 takes up more room than gas
Unlike gas, which needs strict air-fuel ratio
More explosive than gas, timing critical
Injected fuel delivery
Other Possible Storage Methods:
CARBON-BASED FUEL EXTRACTION: depending on the availability of H2/ LH2, for both HICEs and FC vehicles, the onboard production of hydrogen is a possibility, from carbon-based fuels
NANOTECHNOLOGY:graphite nanofiber tubes store 65% H2 by weight.
-DOE funded, then withdrew
-Ford continued the R&D
-GM later questioned the 65%
