To be suitable for gas turbine use, renewable energy resources are typically processed to produce a cleaned gaseous fuel which tends to be of low energy density relative to natural gas. Depending on the process and source, the derived fuel gas may also contain a large fraction of Hydrogen. Such gases may require enrichment to permit stable combustion and also carry some hazard of flashback due to the Hydrogen content. Previous experience also suggests that even small traces of ash which could be carried through the gas cleaning have the potential to cause airfoil fouling.

Allison Engine Company produces engines for electric power generation in the range up to 7 MW and expects to offer derivatives up to 12 MW by the year 2000. Two series of engines are involved, offering different virtues and challenges in renewable fuels use. It is planned to extend the range of renewable fuels utilized by all these engines by carrying out a rig and engine demonstration program. A major goal is to operate a gas turbine using the product gas from a high quality biomass gasifier.
