Gasoline-powered automobiles are being converted to operate on gaseous fuels such as hydrogen (H2) or methane (CH4). The fuel is often stored as a cryogenic liquid (H2 at 20 K and CH4 at 112 K) in dewar-like vessels located in the trunk of the car. Cryogenic storage provides four to five times greater vehicle range than gas storage in high pressure cylinders of comparable volume. Potential leakage of these gaseous fuels into the passenger compartment of the vehicle constitutes a safety threat. Definitive experiments were performed to identify the explosion hazards and establish venting criteria and general safe-guards for H2 or CH4 fueled passenger vehicles. Initial tests were conducted using methane at three inlet temperatures (300, 200, and 121 K). Results are discussed.
