This is an important page and needs to be expanded upon. Currently, the Sabatier Reaction seems to be only used in discussions of how to create rocket fuel from the lunar surface or the martian surface. However, this reaction is potentially interesting for discussions of a hydrogen economy. In particular, methane would appear to be an existing method for transporting hydrogen; it transports 25% hydrogen by weight (compare to carbon nanotubes, glass beads, or metal hydrides); it has better volume properties than pure hydrogen; and there exist fuel cells that will directly consume methane.

Discussions of cost information for synthesizing methane from water and carbon dioxide are hard to come by. Other discussions of how practical it might be to expand the existing methane economy for transportation purposes while recycling carbon dioxide would be interesting. —Preceding unsigned comment added by 66.124.235.194 (talk • contribs) 15:56, 18 March 2005

Currently the reaction goes in the other direction. Most hydrogen is produced from methane. To make the Sabatier reaction go, it requires much cheaper hydrogen, or much more expensive fossil fuels. pstudier 00:40, 2005 Jun 10 (UTC)

The most important thing is the energy balance, even if the prices of hidrogen generation or fuel don't move. But this is a hard work, and the way to do the study can change the results. So, I think that a comparison of a few works is needed. --Proximo.xv 12:07, 12 December 2006 (UTC)
