Here’s a first: a liquid hydrogen-fueled V12 engine that can output 230+ hp. This bi-fuel engine – set to go on display at NHA (National Hydrogen Association) 2006 – will be placed in a limited run 7-series model and is capable of burning gasoline or liquid hydrogen. Read on…

From the article: “There are, however, several critical practical issues with using liquid hydrogen in a vehicle, including: *Hydrogen boil-off. Boil-off impacts cost, efficiency and vehicle range, not to mention safety consideration for vehicles parked in confined spaces. Insulation is needed to keep the temperature ultra-low, and this reduces gravimetric and volumetric capacity. *A high energy requirement for liquefaction of the gas—around 30% of the heating value of the hydrogen.”
