杜克大学研究人员在《Nature Climate Change》上发表报告，认为中国煤制合成天然气计划可能会造成严重的环境问题。中国为治理大气污染采取的一个应对措施是用天然气代替煤炭，但煤制合成气大幅增加水的消耗，同时还会排放大量温室气体。杜克研究人员计算，北京最近批准的9座合成气厂每年消耗的水将超过1.8亿吨，排放的二氧化碳将抹掉风力发电和安装太阳能电池的减排努力。合成气厂需要的水100倍于通过水力压裂获取天然气的方法。报告认为，合成气厂将加重那些本来就缺水地区的压力。研究人员认为，合成气对于中国的能源安全而言可能是件好事，但对环境却是个灾难。This entry passed through the Full-Text RSS service — if this is your content and you're reading it on someone else's site, please read the FAQ at fivefilters.org/content-only/faq.php#publishers.
