Over the past few months, China has published its development plans for the 13th Five Year Plan [FYP] period [2016–2020] for energy, and separately for the electricity sector, renewable energy, hydro, wind, solar, and biomass energy. Here, we review these policies, as well as a number of key supporting policy documents that aim at increased renewable energy use in China. Presuming that China will not overshoot its growth targets for wind and PV, annual additions over the 13th FYP period will average 16 GW for wind and 13.5 GW for PV, well below the growth levels seen in recent years. The key to success in China's continued transition to renewable energy, however, does not lie in such capacity additions alone. At least as important will be the efforts at improving grid interconnectedness, flexibility of generating capacity and the grid, market mechanisms that will reduce and spread electricity demand, and better enable renewables to compete, and efforts at increasing the level of consumption of the renewable power generated.
a b s t r a c tThe main objective of this article is to evaluate CO 2 mitigation potential and to calculate costs avoided by the use of different CO 2 mitigation technologies in China's cement sector, namely energy efficiency improvements, use of alternative fuels, clinker substitution and carbon capture and storage (CCS). Three scenarios are designed based on the projection of cement output and technology development over the next 40 years (2010-2050). 2.5, 4.7 and 4.3 Gt tonnes of CO 2 will be saved totally in basic scenario and two low carbon scenarios up to 2050. By comparing these technologies along the scenarios, it can be concluded that CO 2 emissions can mainly be reduced by energy efficiency improvements and use of alternative fuels. Clinker substitution, which reduces the clinker-to-cement ratio as well as energy intensity, results in significant cost advantages. CCS, including post-combustion capture and oxy-fuel combustion capture, could play an important role in the capture of CO 2 in the cement industry, and is expected to be in commercial use by 2030.Crown
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
