Hythane and Hydrogen I.C.

I'm looking for information on converting a CNG vehicle to run on either Hythane or hydrogen (internal combustion).

Questions:

1. What's involved in converting a CNG vehicle to run on Hythane and/or hydrogen? Can the fuels be used interchangeably?

2. What's the typical power and range reduction when converting from CNG to Hythane or hydrogen?

3. Can Hythane be dispensed from a standard CNG refueling station (assuming H2 available) or is custom equipment required?

Any contacts for Hythane and/or hydrogen conversions would be helpful too!
