Global carbon capture capacity to rise; US$3 bn invested to date
The global capacity for carbon capture in 2030 is set to increase six-fold from today’s level, to 279 million tonnes/year of CO2 captured, according to research company BloombergNEF’s (BNEF) newly released 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 (Figure 1).
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 (Figure 2). This change is being driven by legislation that incentivizes 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.”
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 1-2 billion tons 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.
Even before this legislation, direct air capture was booming. Venture capitalists have poured more than US$1 billion into the technology this year – more than the total amount invested in DAC up to this point. Companies are already becoming more ambitious in their projects. Soon after the US passed its Inflation Reduction Act, a project to build 5 million tonnes of carbon removal capacity in Wyoming was announced.
“In many industries, CCS is a sunset option to get high emissions assets to the end of their life,” said Madrid. “But removals are present in every long-term net-zero model. They are here to stay.”
