Thomas,
Visit 250 Spanner customers or 100 Burkhardt customers. I would expect to find several gasifiers operating just like the wood fired boilers that we build in small institutions: 3-5 hours (max 12) per week of labor, stable fuel consumption, predictable heat and power production, 4,000-5,000 hours operation per year. Then look at the values of the products: heat, power, biochar. Compare gasifier fired heat systems. What is the marginal cost of generating power? What are the circumstances that favor gasification for heat, char, or power? Other gasifiers will be operating for only a few hundred hours per year because of their particular circumstances. I previously used the US Northeast (New Hampshire) as an example because wood fuel is accessible, they have a tradition of wood burning boilers, many nurseries or farms do not have access to natural gas, power is costly, and even a small amount of gasifier char can be used in the nursery growing media as a substitute for expensive materials (vermiculite). Heat and biochar products from one gasifier that we are working on has the potential to return the cost of the system in a year and a half. Although we are making an engine quality gas, and have generated power, it is not worth it in our circumstances. Fracking and directional drilling in this country has brought low cost oil and gas that has eliminated many biomass power projects in the way that Peter described. Still, there are many places that are not on a natural gas line and do not get low cost oil. They would benefit from small scale gasification. We just need suitable systems.

When I started as an inventor many years ago I got an advice from an old man which I have recalled many many times in my carrier I gasification “When you judge the quality of an advice, it is very important to know it the person that gives you the advice, gets his salary every end of the month or he has to fight for his own money every day” 90 % of the bad examples in gasification are initiated/supported or what ever term you like, by people that had no personal consequence of their advice. I can tell you that I really tried to get the gasifier in Gjol to work and lost approx. 1,2 mio € in cash. In 2012 TK Energi went banckrupt. Not because of Gjol – but if I had not spend my money on a hopeless technology that I started working with 20 years before, TK Energi might have survived. I am back in business, developing gasifier again, with the wisdom of 30 years technological failures and a bankruptcy. So Harrie, Can you give me 5 addresses on gasifiers below 1 MW power, in Europe, that have operated for 5000 hours?

The fact remains that there are 100 hundreda commercially operating gasifiers in Europe. Nobody can deny this and lets keepm positive inmsted of all this negative impusles
