Abstract

The present invention concerns apparatus, kits and methods for converting ICE vehicles to run on hydrogen fuel. Certain embodiments of the invention may comprise HIPAs (hydrogen injection port adaptors), hydrogen gas manifolds and hydrogen fuel sources. The HIPAs are designed to replace the spark plugs in internal combustion engines and may comprise a hydrogen input tap, hydrogen channel, spark producer and/or feedback sensor. In some embodiments, a computer and/or CPU may electronically control the timing of hydrogen ignition. In other embodiments, a mechanical timing system may supplement or replace electronic control of ignition timing. In various embodiments, any source of hydrogen fuel may be used. In preferred embodiments, the hydrogen fuel source comprises doped sodium alanate compositions. The hydrogen fuel may be packaged into cassettes or other modular storage systems. Cassettes may be inserted into Decom™ units to provide hydrogen fuel to the vehicle.
