I did read through it, and I can not see what is so bizzare about that study. We have seen worse..... Where they fail in their efford to be transparent, is the high "primary energy input" given for esterification. Seems that this includes the methanol input, but this is not stated or explained.
In total, a result of 0.51 MJ conventional input for 1 MJ renewable BD output is average for studies that look at rape seed Biodiesel AND it does give BD an edge over dinodiesel (where you have to put an extra 1,2 MJ dino input to deliver 1MJ dino output at the pump!). Also it is not explained why they are mad enough to transesterify refined rape seed oil. Raw will do just fine, as we all know. An intelligent system of course would use BD where ever possible in the growing of the oil seed OR used veg. oil as the clever feedstock. But they are starting, they may still learn ;-) Camillo Holecek Biodiesel Raffinerie GmbH, Austria -----UrsprŸngliche Nachricht----- Von: Keith Addison [mailto:[EMAIL PROTECTED] Gesendet: Dienstag, 02.

These guys have also set up a forum for discussion of their report: http://143.52.119.8/SED/RRU/Biodiesel/ There's only one message so far, from Terry de Winne, being on the ball as usual: http://143.52.119.8/SED/RRU/Biodiesel/Lists/Biodiesel%20Report/DispFor m.htm?ID=2&Source=http%3A%2F%2F143%2E52%2E119%2E8%2FSED%2FRRU%2FBiodie sel%2F Valiant effort at being polite. I suggest he could use some support - this foolish report should be scotched before it does harm.
