A hydrogen storage tank was installed last week at what will become the first public hydrogen filling station in the Munich metropolitan area. The station is being opened by a partnership between BMW and Total that plans to open three hydrogen filling stations in Europe by the end of 2007. The storage tank will be Germany's first underground storage tank for liquid hydrogen and means the station will look just like a regular gasoline station. The Total station is being built near BMW Group's Research and Innovation Centre and will open later this year. When it does, it will also offer petrol and diesel. Given all this, once the 7 Series (with the hydrogen combustion engine) comes to market, German will have at least one place to fill up.
