Have you heard of the 6 stroke ic engine, they are between 45% and 50% thermal efficiency. There is a major drawback of using hydrogen and hydrogen rich fuels. 500 Modern busses emit about the same Nox as 2 1960's era busses. Nixon formed the EPA to put the reforms needed to create these massive 250 fold reductions in Nox emissions. The bottom line is hydrogen and hydrogen rich fuel such as Gevo's isobutanol burn hotter which react with No2 to produce Nox (acid rain or smog)when used in ic engines. This issue seems to have been sweeped under the rug.
