剖析京津冀雾霾频发:原煤散烧是空气污染重要来源

2016-01-03 14:25:38   中国新闻网

“煤炭在中国一次能源中的比例还停留在将近100年前世界能源结构的水平上。这种差距的确令人忧心忡忡,但也意味着空间和机遇。”社科院研究生院国际能源安全研究中心主任黄晓勇说,“APEC蓝”或“阅兵蓝”的常态化可以通过努力实现,关键在于决心和措施。

我国已经明确,到2020年,非化石能源占一次能源消费总量的比重达到15%左右,到2030年达到20%左右。同时,逐步降低煤炭消费比重,到2020年,煤炭消费比重控制在62%以内。

近日召开的全国能源工作会议也释放出“控煤”的信号:严格控制煤炭消费,推进重点地区煤炭减量替代。严格控制煤炭新增产能,原则上从2016年起3年内暂停新建煤矿项目审批。

但是,能源结构的调整绝非朝夕之功。我国煤炭资源总量占一次能源资源总量超过90%,富煤、贫油、少气的特点明显。以煤为主的能源结构既有经济性的考量,也有保障能源安全的需求。同时,新能源和可再生能源短期难堪大任,发展壮大和清洁替代尚需时日。

曾经深受雾霾困扰的英国,能源结构调整也延续了数十年。“英国用20年的时间使石油替代了20%的煤炭、用天然气替代了30%以上的煤炭,最终使煤炭占能源结构的比例从90%下降到了30%。”黄晓勇说,结构变化的背后是能源生产、消费、技术、体制的深刻变革。

“用好煤”是现实之举

“这两年入冬,村委会都会集中联系供煤商挨家挨户送煤,居民凭证优惠购买优质煤,政府有补贴。”北京市朝阳区咸宁侯村居民任兴告诉记者。

没错,就是在北京,也有居民需要烧煤取暖。既然现阶段煤炭仍然不得不用,那么,如何“用好煤”自然成为关键。

一方面,“用好煤”是指要用“好”的煤。近年来,我国不断强化商品煤的质量管理。国家发展改革委副主任连维良近日表示,要严格限制高硫、高灰劣质煤生产使用。对尚未开发的高硫、高灰煤,要暂停煤矿项目核准,已投产的要减少产量,立足就近销售,不得长距离运输。

另一方面,“用好煤”是强调“好好用煤”,真正做到清洁高效。

“我国燃煤造成的环境问题主要是7亿吨的散烧煤,散烧煤关系供暖、供热,关系民生,其最佳的替代就是电能。”中国煤炭工业协会咨询中心专家左前明说,发达国家将80%以上的煤炭转换为电力,而我国只有50%,要进一步提高电能的消费比例和电煤在煤炭消费中的比例。
