Energy Potentiality of Crops Straw Resources in Yunnan

Abstract:

Crops straw is very important biomass resources. This paper estimated biogas potential, biogas generating capacity and the amount of standard coal alternative according to the production of crops straw from 2000 to 2010 in Yunnan Province. The results indicated: the amount of straw resources reduced in 2002 and 2003, it began to rise in 2004 and larger increase in 2007. Then the amount of crops straw reached 1485 ten thousand tons in 2010. It can produce 2.97 × 109m3 of methane. The biogas production can meet the need of almost 5.42 million farmers in the daily life each year, it can solve more than half of rural farmer’s needs in Yunnan Province. Biogas generation capacity can reach 4.75 × 109kWh, the production of biogas can replace 2.08 × 109kg of standard coal.
