Abstract: China has become increasingly dependent on the international energy market owing to the rapid growth of demand for energy. To develop renewable energy and thus strengthen energy security for the future, it is important to consider the potential of crop residues. This paper contributes to this topic by mobilizing up-to-date statistical and remote-sensing data and by carrying out a geographic and economic analysis. Its assessment shows that China's total output of crop residues in 2010 amounted to 729 million tons, and the quantity could be used for commercial energy production is between 147 and 334 million tons, depending on the competition power of the commercial energy production relative to the traditional uses of crop residues. The analysis also shows that the distribution of crop residues in China is highly uneven. By taking into account the densities of crop residues available for energy production at the grid-cell level, the transportation cost constraints, and the economy-of-scale requirements of energy plants, this study further assesses the geographic distribution of the suitability for establishing crop residue based power plants and bioenergy plants in China.

Abstract: China’s forest bioenergy policies are evolving against the backdrop of pressing national energy challenges similar to those faced by OECD countries, and chronic rural energy challenges more characteristic of developing countries. Modern forest bioenergy could contribute to solutions to both of these challenges. However, because of limitations in current technologies and institutions, significant policy and resource commitments would be required to make breakthroughs in either commercializing forest bioenergy or modernizing rural energy systems in China. Given the potential attention, funding, and resource trade-offs between these two goals, we provide an argument for why the focus of China’s forest bioenergy policy should initially be on addressing rural energy challenges. The paper concludes with a discussion on strategies for laying the groundwork for a modern, biomass-based energy infrastructure in rural China. [Copyright &y& Elsevier]

Abstract: This paper assesses the sustainable biomass resource for energy in China. Assessment has been carried out for the following resources: (i) agricultural residues, (ii) forest residues, and (iii) municipal solid waste (MSW). The potential of each resource is estimated for the base years 2008, 2008, and 2007. The energy potentials of these resources in 2008, 2008, and 2007 are estimated to be 14.7, 3.9, and 0.2EJ, respectively. The total potential including the energy of 6.4EJ from the proposed low-input high-diversity (LIHD) grassland biomass on the untilled lands for the base years 1996 is equal to about 30.2% of China’s energy consumption in 2008. Furthermore it is projected that sustainable biomass use for energy will reduce net emissions of green house gases (GHG) of 3276.7 million tonnes, and help in emission-reduction target of China and the world.
