Not so fast. You can't write off "tar making" gasifiers completely. While your observation may be true for hundreds of low cost gasifiers now in use, in the last five years I have seen three small scale gas cleaning systems using wet scrubbers that would pass California air quality and safety regulations. One is produced commercially and was demonstrated at the 300 kWe scale. Another was demonstrated at 300 KWe and used on a 1 MWe system. One was demonstrated on a 100 kWe downdraft gasifier generating 100 kWe from grass seed screenings. I know of another two in development for the 40 kWe scale. (I also know of at least one that has failed miserably.) Tar making gasifiers may be a solution for some very difficult but abundant fuel like rice husks and agricultural residues if the tars can be managed and destroyed acceptably.
