By 2050, CCUS could represent more than 25 percent of the emission reduction for iron and steel and more than 60 percent for cement, according to the IEA. The industry will remain the first for captured carbon emissions, but bioenergy with carbon capture and storage (BECCS) is expected to grow as a negative emission solution and will represent more than 20 percent of the captured CO2 by 2070. Overall, the captured CO2 would most likely be stored rather than reused.

But the development of CCUS is generally perceived to be challenging because of four obstacles: unfavorable economics for industries, a challenging scale-up, the regulation gap, and the lack of public support. To achieve net-zero objectives, governments need to develop CCUS policies and regulations to incentivize companies to invest and to raise public awareness. The United States remains by far the main contributor to CCUS development, but Asia and Europe are investing.
