CCS需要很多钱吗?
CCS需要很多钱吗?

组织: 全球碳捕集与封存研究院

主题: CCS, 成本

在本世纪中叶之前实现净零排放,碳捕集与封存(CCS)一项必不可少的技术工具。但是,有关CCS的文章和评论通常不乏描述部署CCS所需费用的字眼,如“昂贵过分昂贵难以负担不经济等等。因此,反对部署CCS的常见论点是,这是一项昂贵的减排方法。

本院媒体宣传高级顾问Lucy Temple-SmithLee Beck撰写的这份摘要表明:

  • 要想在本世纪中叶实现净零排放并实现全球气候变化目标,那么必须采取一切脱碳方案。
  • 碳捕集与封存(CCS)发挥了重要作用,将排放量减少到零净值并限制了脱碳的总体系统成本。
  • 由于应用场景多样,CCS在其各种工业和与电力相关的应用中成本不尽相同,没有统一成本。
  • 考虑到气候危机的紧迫性,成本不应遏制对CCS的投资,也不能决定脱碳方案的部署顺序。部署反而能降低成本。
  • 必须给碳赋予价值,只有这样才能证明大规模CCS部署的商业可行性并克服那些技术上不可逾越的障碍。
