In general, the process of gasification uses high heat and low oxygen to turn carbon-based fuel into energy. This process differs from standard combustion because it uses far less oxygen, and it relies on a series of stages to make the process happen.
Wood fuel is cost-effective. Wood pellets are composed of leftover wood material and are economically competitive with other fuels used for heating. Prices of wood pellets are often stable because they do not depend on exogenous factors such as fossil fuels.
Wood pellet is a renewable fuel source and does not cause net carbon dioxide (CO2) emissions when burned, as the amount of CO2 released from combustion is equivalent to the amount of CO2 absorbed by trees during combustion.
