1、KEY CONSIDERATIONSPOLICY&FINANCINGOUTLOOKTECHNOLOGIES&COSTSCarbon capture and storage:from turning point in 2025 to scale by mid-centuryENERGY TRANSITION OUTLOOK CCS TO 2050FOREWORDThe surge in installation reflects a widening appreciation of the decarbonization role of CCS.So far,the heavy lifting

2、on carbon capture development has been done within oil and gas production for natural gas processing and enhanced oil recovery.But after 2030,the market for CCS will increasingly address hard-to-decarbonize emission sources.With this shift,we forecast that North America will be joined by Europe as a

3、 leading region for CCS deployment.In the hierarchy of emissions reduction strategies,the first consideration should always be energy efficiency.Next is the use of renewables to replace fossil energy sources.Finally,there is CCS,which occupies an increasingly important niche:tackling emissions in ha

4、rd-to-decarbonize sectors.This includes CCS for process emissions in manufacturing,and in the production of low-carbon hydrogen from the steam reforming of natural gas.Our forecast is that CCS will grow significantly:from 41 Mt/yr today to 1.3 Gt of CO2 captured and stored Ditlev EngelCEO DNV Energy

5、 Systemsin the year 2050.That is a big uplift,but it falls short of where CCS should be in a net-zero outcome.Furthermore,we forecast that energy-related emissions roughly halve from today to 2050,and so,ironically,it is in todays high-emitting world where CCS is best applied.The biggest barrier to

6、the very much needed acceleration of CCS deployment is policy uncertainty.Policy shifts,not technology or costs,have been responsible for many CCS project failures.However,policy support for CCS is firming across most world regions.Indeed,carbon markets and voluntary offsets will evolve to the point

根据报告的内容,本文主要概括了以下关键点: 1. CCS技术包括碳捕集、运输和储存三个关键步骤,用于减少工业排放源中的二氧化碳排放。 2. 目前,全球已安装的碳捕集能力为6200万吨/年,其中胺吸收技术是最成熟的商业化碳捕集技术。 3. 直接空气捕集(DAC)是一种负排放技术,可以从大气中直接捕集二氧化碳,目前技术仍处于早期开发阶段。 4. CCS在难以减排的行业中发挥着重要作用,如水泥、钢铁和化工生产,这些行业的二氧化碳排放不仅来自化石燃料,还来自工业过程。 5. CCS的部署面临政策不确定性、公众反对、商业模式和融资等挑战,需要政策支持、碳市场和法规来推动其发展。 6. CCS的部署预计将在2025年达到转折点,到2050年,预计每年捕集和储存的二氧化碳将达到13亿吨,占全球排放的6%。 7. 为了实现净零排放,CCS的部署规模需要比预测的水平大6倍以上,特别是在难以减排的行业中。 8. 到2050年,碳去除技术预计每年可以捕集和储存3.3亿吨二氧化碳,占CCS总捕集量的25%。
