It is always difficult to evaluate the suitability of equipment without some reference to specific operating systems and the circumstances (fuel, finances, infrastructure) that they are used in. While databases or interactive case studies are useful to have they don’t always tell you what you need. There were some very good technical and economic profiles that were prepared for various gasifiers in the 1980s. I think that something like a good questionnaire along with contact and follow up information could be useful. Each IEA Task 33 country could prepare something or circulate a questionnaire for commercial gasifiers in their countries. Preparation of the questionnaire or database information should be done carefully. I don’t know who would be interested in funding such an effort but it would be useful to have. <o:p></o:p></span></p><p class=MsoNormal><span style='color:#1F497D'><o:p> </o:p></span></p><p class=MsoNormal><span style='color:#1F497D'>Tom <o:p></o:p></span></p><p class=MsoNormal><a name="_MailEndCompose"><span style='color:#1F497D'><o:p> </o:p></span></a></p><div><div style='border:none;border-top:solid #B5C4DF 1.0pt;padding:3.0pt 0in 0in 0in'><p class=MsoNormal><b><span style='font-size:10.0pt;font-family:"Tahoma","sans-serif"'>From:</span></b><span style='font-size:10.0pt;font-family:"Tahoma","sans-serif"'> Gasification [mailto:gasification-bounces@lists.bioenergylists.org] <b>On Behalf Of </b>Harrie Knoef<br><b>Sent:</b> Thursday, September 25, 2014 1:09 PM<br><b>To:</b> 'Discussion of biomass pyrolysis and gasification'<br><b>Subject:</b> Re: [Gasification] Cost and Performance of Small Scale Gasifiers<o:p></o:p></span></p></div></div><p class=MsoNormal><o:p> </o:p></p><p class=MsoNormal><span style='color:#1F497D'>Dear Tom, do you have a special reason to start this discussion?

Although the information you are looking for is not available, one can conclude from these successes that they are competitive in the market and can be considered fully commercial, also providing guarantees. This success is partly due to the attractive feed-in tariffs.
