Gasification is a process that converts organic materials into carbon monoxide, hydrogen and carbon dioxide. This is achieved by reacting the material at high temperatures (>700 C), without combustion, with a controlled amount of oxygen and/or steam. The resulting gas mixture is called syngas which is itself a fuel. The power derived from gasification and combustion of the resultant gas is a source of renewable energy if the gasified compounds were obtained from biomass. When wood is gasified, the resulting gas has a heating value of 5.7 MJ/kg. If the efficiency of conversion of wood to gas is 20% and the conversion efficiency of burning wood gas to generate electricity is 30% how many Tonnes of wood are needed to generate 30 MW of electricity continuously for 200 days?
