Contact, Soalar and Biogas research center, at Birla Engineering College, V.V.Nagar, Gujarat, India-388120., if possible. They are running, I.C engine, with wood debris.
The Combustion, Gasification and Propulsion Laboratory where I spent some forty years has done substantial work in this area - for power from a few kWe to several MWe using biomass gasification, thermal power generation from 1 kg/h to 100 kg/h for coarse thermal applications and 100 to 1000 kg/h of thermal biomass gasifiers. By biomass is meant briquetted agroresidues or chipped wood in a range of sizes depending on the power level. All the scientific and technological is documented in accessible web location - http://cgpl.iisc.ernet.in. If there are further scientific or technological questions of any nature I will be able to respond.
