BMW announces bi-fuel hydrogen/gasoline car
BMW has announced the Hydrogen 7, a new BMW that will supposedly reach production next year. Not a fuel cell car, but rather an internal combustion engine that can run on either gasoline or hydrogen. It doesn’t appear to be terribly fuel efficient, but when run on hydrogen it will be virtually emission-free (at the tailpipe). There are plenty of arguments against hydrogen as a fuel, largely stemming from the fact that the easiest way to produce hydrogen comes from natural gas and is inefficient to produce.
