There are three main types of technological carbon capture today (with many more in development): industrial-point-source CCUS, direct air capture (DAC), and bioenergy with carbon capture and storage (BECCS). An overview of CCUS: Will it finally arrive? Future articles will discuss other scaling requirements, such as lowering the costs of implementing CCUS and developing hubs and clusters. Specifically, we map how the industry can generate revenues and move beyond a subsidy-only business model, and we discuss what governments, investors, and industry players can do to help scale the technology. This article explains what the CCUS industry can do to overcome historical challenges and reach the scale required for net-zero emissions. Even in conservative scenarios, CCUS demand would reach approximately two GTPA by 2050-a 60-fold increase over today’s pipeline of projects.ĬCUS uptake needs to grow 120 times over by 2050 for countries to achieve their net-zero commitments.ĬCUS is recognized as a necessary and relatively low-risk piece of the decarbonization puzzle, but the technology is not moving fast enough to achieve a 1.5° or even 2.0° pathway. ![]() This could lead to CCUS decarbonizing 45 percent of remaining emissions in the industry sector. per annum (GTPA) of CO₂ captured, with some estimates ranging from 6.0 to 10.0 GTPA. (2022).Īccording to McKinsey analysis, CCUS uptake needs to grow 120 times by 2050 for countries to achieve their net-zero commitments 3 A total of 139 countries (covering 91 percent of global emissions) have committed to net-zero emissions., reaching at least 4.2 gigatons 4 Metric tons: 1 metric ton = 2,205 pounds. 2 For more, see Inflation Reduction Act of 2022, H.R. For example, the recent Inflation Reduction Act (IRA) in the United States includes an enhanced tax credit for the permanent sequestration of CO₂, which could rapidly boost adoption and help scale CCUS facilities. To meet their emissions reduction commitments, governments have begun enacting policies to support the development of CCUS. For example, Ireland-based CarbonSpace has designed a satellite power tool that estimates the biospheric emissions and sequestration of carbon sinks.This article is a collaborative effort by Krysta Biniek, Phil De Luna, Luciano Di Fiori, Alastair Hamilton, and Brandon Stackhouse, representing views from McKinsey’s Oil & Gas Practice. CarbonSpaceĪnother way to sequester carbon is by using nature-based solutions. “The low biodegradability of biochar ensures that it remains effective in the long term and can be considered a permanent carbon store,” she says, adding it can be used as a feed additive, bedding in barns or in manure treatment.Īccording to zu Dohna, “the PYREG technology is fully proven and commercialised,” and the startup will have 50 installations with a yearly CO2-equivalent sequestration capacity of 30k tonnes by the end of 2022. This makes it good for use in agricultural applications. Henriette zu Dohna, its PR and communications manager, says biochar’s highly porous structure means it has a water and nutrient uptake capacity of five times its own weight. PYREGĪnother biochar startup is Germany-based PYREG. “We want to keep the cycle going and really go into the circular economy.” 5. We want to use it because we need carbon,” she says. “It doesn’t make any sense to store biochar underground or put it somewhere in a mountain. Lepel adds that a significant hurdle is scalability but utilising carbon through different applications could alleviate that problem. “It brings up the fertility of the soil and it prevents leaching. “What is best researched is actually a function as a soil amendment,“ says Lepel. ![]() While still under research, Lepel says biochar’s most promising use case involves soil. “We take atmospheric carbon and we transform it through a process called pyrolysis into a stable form, in a solid form of carbon that looks like charcoal.” “Biochar is essentially just carbon,” says Venna Lepel, the startup’s chief commercial officer. One use of carbon is biochar, a solid material that can be used to build concrete, plastics or soil, and Germany-based Novocarbo is making it. “If we actually convert it into something, repurpose it and treat it more like a resource, that’s going to be the way forward rather than simple sequestration,” says Tunnicliffe. She adds that the way we think about carbon has to change, because it’s not enough to just remove it and store it - it needs to be useful. ![]() Right now, the startup is manufacturing material for a small number of clients, but Tunnicliffe says it can be scaled up using a “copy and paste format”.
