余卓平:光伏发电成本降低到0.2元/千瓦时 光伏制氢可与化石能源竞争

光伏系统工程  来源:人民日报  作者:丁怡婷  2021/4/22 11:35:21 北极星太阳能光伏网讯:记者21日从中国氢能联盟举办的“十四五”氢能产业发展论坛上获悉:截至2020年底,全球加氢站约为544座,我国建成加氢站128座,氢燃料电池汽车累计保有量达7000多辆。 2019年,我国氢气产量中,煤制氢占63.54%、天然气制氢占13.76%、工业副产氢占21.18%、电解水制氢仅占约1.52%。产能主要集中在西北、华北和华东地区。不少专家认为,未来在应对气候变化的大背景下,可再生能源制氢是主要的发力方向。 未来,风电、光伏等可再生能源电解水制氢的成本是否具有竞争性?中国氢能联盟专家委员会主任余卓平分析,如果到2025年我国风电、光伏的新增装机发电成本降低到0.3元/千瓦时,可再生能源电解水制氢成本将降到约25元/千克,能够与天然气制氢进行竞争。等2030年可再生能源发电成本降低到0.2元/千瓦时后,电解水制氢成本将低至15元/千克,可以与现在化石能源加上碳捕集技术制氢的价格进行竞争。 中国科学院院士徐冠华建议,氢能产业要建立起资源共享、优势互补、利益共享、协同配合的合作机制,防止一哄而上、一松而散;与此同时,注重基础研究和前沿技术研究在氢能产业发展中的重要性,关键技术的研发需要脚踏实地,在应用中不断提升。
