Randall (“FuturePundit”) Parker takes down hydrogen cars by pointing to a number of scientific studies.

The biggest problem with hydrogen as a means to reduce pollution is that it has to be produced from another energy source and the most cost competitive energy sources are all forms of fossil fuels. The production of the hydrogen is not 100% efficient and it produces pollution. The transportation and storage of the hydrogen also use energy.

He deflates hydrogen even more emphatically than Lynne Kiesling, whose analysis I linked to in March.

For Discussion. Is there another side to the hydrogen story that I need to know about?
