Biomass Resources, Technology Options, and BarriersBiomass resources. Current and 2020 projections of biomass availability underscore the potential for achieving the countrys 2020 goals of developing sustainable rural biomass energybut only if these wastes can be harnessed. As a large agricultural country, the PRC has a variety of biomass resources in substantial quantities across wide areas. The forms of biomass discussed in this publication come from two kinds of wasteslivestock manure and crop stalksand another type of biomass that is actually produced for creating energy is energy crops for liquid biofuels. As an example of the xiv PRC Rural Biomass Energy 2020loss and opportunity currently found in the countrysides biomass resources, the amount of livestock manure alone in 2005 could have met 28% of rural household energy needsif it had been converted into biogas. Unfortunately, only 12% of animal waste from household farms was put to energy use and worse, only 0.5% of animal waste from industrial livestock farms was used for energy.3 The scenario for crop residues is similar. About 0.4% of the total amount of straw biomass was used in renewable energy systems. Technology options. Encouragingly, the PRC government has already planted the seeds to grow a rural biomass energy industry. Knowledge that biomass can be converted into a clean, convenient fuel is also growing at national and local levels. Proving that biomass energy is catching on, household biogas production increased 340% from 2000 to 2008, while animal waste increased by only 112%. While there is still room for improving household biogas digesters, their further deployment does not face the same challenge as do the larger, more centralized systems. The report evaluated 15 technologies that can convert biomass resources to heat, electricity, solid fuel, liquid fuel (ethanol, biodiesel, etc.), and gaseous fuel (biogas, biomass fuel gas, hydrogen). Through economic, environmental, and social assessment, six technologies that ranked the highest in this assessment are discussed in the report: (i) rural household biogas systems, (ii) medium and large biogas plants, (iii) straw briquette/pellet fuel, (iv) electricity from straw, (v) crop straw gasification, and (vi) bioethanol and biodiesel. These more sophisticated technologies need to be developed through research and piloting if they are going to contribute significantly to meeting rural and national energy demands. This publication, using a scorecard system, summarizes the results of a comprehensive study of the above six technologies. The technology barriers can be overcome, though, as Chapter 4 explains, through adequate research and piloting. Barriers. Even though the country is endowed with rich biomass resources, rural biomass energy is still
