The article 'Green Cars with a Proof?', published by AutoWeek and Crain Communications, is a detailed, but forward piece intended for teens or older interested in the processes of improving the hydrogen car. It is different than the other articles I have cited because a large chunk of it consists of the possibilities for transporting hydrogen. It highlights the main ideas of why it would be hard to switch to a hydrogen-economy, such as costs, technological challenges, and public awareness.
