2020年后,中国光伏年新增装机将以80~160GW“光速”发展

2020年后,中国光伏年新增装机将以80~160GW“光速”发展 中国未来能源供应结构正逐步由以煤炭石油为主的化石能源向非化石能源转变,国内可再生能源的使用比例将在2050年大幅度提升。 18日,在2018国际能源变革论坛上国家发改委能源研究所副所长王仲颖发布了《中国可再生能源展望》,报告指出,中国化石能源消费总量将在2020年达峰,2035年之前稳步下降。由于未来可再生能源经济性全面赶超化石能源,中国不需要将天然气作为煤炭与可再生能源之间的过渡性能源。 以煤炭为例,2012-2017年间,我国煤炭消耗量在能源消费中的占比在逐年降低,年均降低1.3%、五年累计下降8%,而清洁能源的比重上升了7.5%。 随着发电经济性的提高,下个10年中国将迎来光伏与风电大规模建设高峰。2020年后光伏与风电将增长迅速,新增光伏装机容量约80-160GW/年,新增风电装机约70-140GW/年。 王仲颖表示:“2050年中国需要70亿吨煤消费量,难以支撑生态环境的改善和恢复。供电脊梁是风光为特征的电力系统革命,未来高比例可再生资源将主要依靠风电和光电,以2度情景风电、光伏装机为例,2050年风电装机将达到26.6亿千瓦,光电装机达到28.4亿千瓦。” 据统计,2017年底中国可再生能源总装机约6.5亿千瓦,占比全国总装机36.6%。其中,水电装机(含抽水蓄能)3.41亿千瓦,风电装机1.64亿千瓦,光伏发电装机1.30亿千瓦,生物质发电装机1476万千瓦,发展空间巨大。
