Tom I just want to point your attention to a danish project that was announced a few years ago .
Vølund - whose gasifier actually work - sold 2,25 Billion DKK ~ approx. 450 mio US $ worth of gasifiers to Italy - http://ing.dk/artikel/88155-milliard-gennembrud-for-dansk-forgasning-af-traeflis - But as far as I know not one gasifier was delivered. The electricity price was 270 €/MWh. I have no idea why - but maybe the production cost of the electricity from the gasifier is higher. I was approached by the same people - they wanted to build one of my gasifiers in southern Italy. But before we could start the project the project had to deliver a boat ++ to local people. Thus the real money left to build the gasifier was nat as much as one could calculate from the beginning. I have no information about any technical successes resulting from these very high green electricity prices - do you have? We achieved close to 12000 hours with our 3 stage gasifier in Japan - electricity price 1-2 $/kWh depending on calculated depreciation time.

As you say I think the percentage of low end gasifiers that are actually working may be pretty low. When we get our gasification website back online we'll try to survey and report on some of these. (We're under a major overhaul due to high traffic.) Any industrial gasifier or boiler is going to have to hit basic targets for efficiency and reliable operation whatever the targets are: 20-25% fuel to power (NCV); and, 4,000, 6,000, or 8,000 hours per year. I know of gasifiers that have difficulty making a few hours a day. You need at least 13 hours per day to make 4,000 hours per year (310 days). The target for the UBC gasifier is 7500-8000 hours per year. They achieve that with their heat units. They operated a 250 kWe gasifier for 3,000 hours. I saw it a couple of years ago at 1,000 hours. There have been many design changes since then. Once the reliability of the 2 MWe system is demonstrated then you can build 6-8 MWe systems where you have significant economies over steam systems. But you need a good power contract (or savings) and you need a use for waste heat. We hear that Europe (UK, Italy) is the best place for good power contracts and high heating costs these days so we should see many gasification plants being built there.

Concerning you statement about Ankur - in the summer 2010 I visited 13 gasifiers in Srilanka - 5 of them Ankur - none was working when I was there - they told me that they needed a rebuild of the hot zone every 2-3 weeks. I also visited a gasifier from TERI - it have had 2-3 hours operation before the engine exploded and it was never put back in operation. To me it looked like they had never build a gasifier before. Of the 13 gasifier 3 was in operation - and one producing electricity.

While we get estimates and budget quotes for 0.5-1 MWe systems at $4,000-$6,000/kWe, the ones that are actually running at 2MWe are $8,000-$10,000/kWe. The exceptions are the Sakata and Ankur gasifiers in Thailand.
