A new study by DNV projects a significant expansion in carbon capture. From the current 41 million tons captured per year, the volume could reach 1.3 billion tons by 2050, representing an approximately 30-fold increase. This growth is not only significant in scale but also marks a decisive moment for the global adoption of this technology.

By 2030, the global carbon storage capacity is expected to quadruple, driven especially by natural gas processing sectors in North America and Europe. After this phase, the manufacturing industry along with the cement, steel, and chemical sectors is expected to take the lead, accounting for 41% of the CO₂ captured by 2050.

According to DNV, achieving this scenario will require an estimated investment of 700 billion dollars by 2050. The good news is that the cost of the technology is expected to decline, potentially being reduced by up to 40% over the coming decades as projects scale up and mature.

Despite this growth, the study highlights that carbon capture will still cover only 6% of the projected global emissions by 2050. This demonstrates that the technology is part of the solution but does not replace the need to expand renewable energy sources and reduce emissions at the source. The report also points out that only robust public policies — such as subsidies, tax incentives, and specific regulations — will be capable of accelerating large-scale deployment of carbon capture.

Another highlight of the study is the advancement of carbon removal technologies, such as Direct Air Capture and BECCS (bioenergy with carbon capture and storage). These solutions, known as Carbon Dioxide Removal (CDR), are expected to account for up to 25% of the total carbon captured by 2050.

Among the strategic sectors, the manufacturing industry stands out as a key player. In segments where electrification or fuel substitution is not feasible, carbon capture emerges as the main alternative to mitigate climate impacts.

Why does this matter?

Carbon capture offers a direct response to emissions that are difficult to avoid with other solutions. Its advancement represents a real opportunity to decarbonize heavy industries, reduce environmental impacts, and accelerate the transition to a low-carbon economy. However, the success of this strategy depends on a combination of technological innovation, economic feasibility, and clear public policies.
