捕獲的二氧化碳的用途也將發(fā)生重大變化。去年,大約73%捕獲的二氧化碳用于提高原油采收率。到2030年前,儲(chǔ)存在地下深處的二氧化碳將使采油作業(yè)成為主要目的地,其中66%的二氧化碳將流入專門的儲(chǔ)存地點(diǎn)。推動(dòng)這一變化的是鼓勵(lì)儲(chǔ)存而非利用二氧化碳的立法,以及旨在使用碳捕獲和儲(chǔ)存(

BNEF的CCUS分析師、報(bào)告的主要作者戴維·路易斯·馬德里表示:“CCS正開始凸顯優(yōu)勢(shì)。它現(xiàn)在被用作脫碳工具,這意味著二氧化碳需要被儲(chǔ)存起來。在工業(yè)或發(fā)電點(diǎn)源附近缺乏二氧化碳運(yùn)輸和儲(chǔ)存地點(diǎn)可能是CCS發(fā)展的主要瓶頸。但我們已經(jīng)看到滿足這一需求的項(xiàng)目大幅增加。”

Global carbon capture capacity 'to rise sixfold by 2030'
The global capacity for carbon capture in 2030 is set to increase sixfold from today’s level, to 279 million tonnes of CO2 captured per year, according to research company BloombergNEF’s (BNEF) 2022 CCUS Market Outlook. Drastic growth in the market has led to a 44% increase in expected 2030 capacity compared to last year’s outlook.
Carbon capture, utilisation and storage (CCUS) is a key technology needed to decarbonise hard-to-abate sectors such as petrochemicals and cement, and to provide 24/7 clean power through gas plants fitted with capture equipment. Still, despite significant acceleration in the sector in the past two years, the world’s capacity for carbon capture is not being deployed fast enough to meet climate goals at the end of the decade, according to BNEF research.
Today, most capture capacity is used to collect carbon dioxide (CO2) from natural gas processing plants and used for enhanced oil recovery. By 2030, most capture capacity will be used for the power sector, for the manufacture of low-carbon hydrogen and ammonia, or to abate emissions from industrial sources.
Carbon captured today
The amount of CO2 being captured today is 43 million tonnes, or 0.1% of global emissions. If all the likely projects that have been announced come online, there would be 279 million tonnes of CO2 captured every year by 2030, accounting for 0.6% of today’s emissions.
The destination for captured CO2 is also due to change significantly from the status quo. In 2021, some 73% of captured CO2 went to enhanced oil recovery operations. By 2030, storing CO2 deep underground will overtake oil recovery as the primary destination for CO2, with 66% of it going to dedicated storage sites. This change is being driven by legislation that incentivises storage over CO2 utilisation, and by projects that aim to use carbon capture and storage (CCS) as a decarbonisation route and must store the CO2 to meet their goals.
“CCS is starting to overcome its bad reputation,” said David Lluis Madrid, CCUS analyst at BNEF and lead author of the report. “It is now being deployed as a decarbonisation tool, which means the CO2 needs to be stored. A lack of CO2 transport and storage sites near industrial or power generation point sources could be a major bottleneck to CCS development. But we are already seeing a big increase in these projects to serve that need.”
Global emissions
Despite rapid growth in capture project announcements, the industry is still far from making a dent in global emissions. In order to be on track for net-zero and less than 2 degrees Celsius of warming by 2050, between one and two billion tonnes of CO2 would need to be captured in 2030, an order of magnitude higher than current plans. Legislators have recognised this mismatch and are ramping up their support for the industry.
The Inflation Reduction Act passed in the US increased tax credits for CCUS by 70%, making a viable business case for the technology in petrochemicals, steel, cement, and in some regions, power. Incentives like these mean that countries, such as the US, will remain global leaders for CCUS. The US tax credits are now very generous, and the law is set to supercharge project announcements in the ethanol and petrochemicals sectors, as well as in direct air capture (DAC), to provide high-quality carbon offsets for the voluntary market.
“This 279 million tonnes of capacity in 2030 is just the tip of the iceberg,” said Julia Attwood, head of sustainable materials at BNEF. “We haven’t seen the full impact of these credits yet, making this outlook a fairly conservative view of the future of carbon capture and storage. We expect to see another jump in announcements in 2022, especially in the US as developers there rush to make sure they meet the 2032 deadline for credits.”
