15. What about liquid hydrogen?
Liquid hydrogen is being proposed by BMW, Linde, and the German government. Linde is the largest gas supplier in Western Europe. This group is planning to build a series of hydrogen service stations using liquid hydrogen. The cost of the stations and the cost of the hydrogen itself is three to four times the cost of HYDRNOL.
In Germany, the stations will use robotic fillers to deliver the ultra-cold liquid to the on-board tanks. These robots are expensive and not required with HYDRNOL.
The tanks for liquid hydrogen are very complex, in order to prevent the hydrogen from spontaneously boiling off. They are also very expensive. Despite heavy insulation, the 10 kilograms these tanks typically hold will be gone after 45 days of sitting.
There's no worse feeling
There's no worse feeling than when you're in an interview and the interviewer asks you a question to which you don't know the answer. A great collection of standard job interview questions are available on web. These are more the traditional questions employers ask, often at first interviews. Review these typical interview questions and think about how you would answer them.
