Biodiesel from flue gas emissions

You remember that thing I picked up a few days ago about people using algae to make biodiesel from flue gas emissions? At the time I was a little sceptical about the idea,mostly because Iwas thinking that all that would happen with the process is delay the emissions of carbon dioxide until the diesel is used.
The seeker, I guess that’s the person who writes seeker blog seeker blog has picked the story up from Robert Rapier on his R squared blog . They’re both more than a little enthusiastic. And they’re both right to be more upbeat about it than I was. The clever bit really is in getting an extra cycle out of the carbon before it is finally released.

If most coal/gas burning power stations are under 50% efficient, then potentially there’s a lot of biodiesel to be made. How much marginal fuel it will replace remains to be seen and depends on the efficiency of the algae, and the energy it will take to extract the diesel.

Now, if we could get a hold of the carbon dioxide released by transportation as it is used… that would be great.

    Another study shows that biodiesel from algae is not economically feasible. Check out http://biodieselfever.com/?p=4 – you will understand that with the value of 1 ton of algae you can BUY more biodiesel than you MAKE from it.
