FIGURE C-3 Life cycle energy consumption for biomass power generation in China. combustion. We can see that biomass cultivation is the main stage responsible for emissions, producing more than 70 percent of the CO2, while the emissions in the collection, transportation, and pre-treatment stages are much lower. Considering the consumption of fossil fuel, the cultivation stage still dominates, due mainly to fuel used in the production of nitrogen fertilizer and the use of diesel. As mentioned above, there are three technology routes for biomass power generation. In China, direct-combustion generation currently is the most developed technology. Due to lack of policy support, co-firing only accounts for a very small share. In addition, most gasification power generation projects are only in the demonstration phase. Different biomass generation systems were compared with respect to energy conversion efficiency and CO2 emissions. As shown in Figure C-4,
