Return to Top comment: Critical questions by Birgir Norddahl [Comment posted 2009-03-03 13:33:02] There is no doubt that 2. generation biofuels can boost economy. It is, however, not all fuels that is the target for the future development. Bioethanol is probably not a good choice. It does not have an energy density high enough to be used as jet fuel and car manufacturers will probably within a few years skip the gasoline motor and develop high efficient diesel engines, hybrids and electical motors with efficient batteries instead. The question I would like answered is when do the motor manufacturers stop producing gasoline motors? The answer to this question will make it a lot easier to predict future targets for development in this field.

I say "much less" because the higher cost to replace the carbon-emitting fossil fuel is well justified for decreasing the damages to the environment and health. Comment on this blog |
