Pine wood is sometimes used as a type of standard energy feedstock for gasification system testing. When research scientists use the same (or a very similar) feedstock for testing, the results can be understood and interpreted most easily because the performance of a thermal gasification system is highly dependent of the feedstock type; therefore, it is useful to evaluate the system performance when using a standard feedstock. Pine wood is used as a standard energy feedstock by some gasification researcher teams in the USA.
