An engineering study of the technical problems expected with the large-scale introduction of hydrogen H2 as a fuel has been initiated. Information was gathered and evaluated regarding H2 generation, transportation and utilization as an engine fuel. H2 generation by coal gasification, electrolysis and thermochemical processes using nuclear heat sources was investigated. Although embrittlement by H2 might weaken the pipeline itself, the principal problem expected in this mode of transmission appears to lie with existing compressors. A novel regenerative, compressor is discussed in this regard. Fundamental relationships between fuel properties and reciprocating engine performance parameters are established and form a rational basis for evaluating H2 vs. gasoline as a fuel. An extensive review of published results revealed that H2 was capable of highly efficient, low polluting operation of such engines when fuel-lean mixtures were used.
