Carbon dioxide (CO2) capture is critical for emission reduction. Biochar a promising adsorbent CO2 capture. In this work, the effect of relative humidity and biochar activation with steam or KOH treatment on was investigated. The results demonstrate that sample activated by has high capacity (50.73 mg g−1). addition, after 1.0 h showed carbon 38.84 g−1. also show ability decreased as concentration from 100% to 15%. had negative impact over biochar. capability materials treated range 31.38%–62.89% rose 8.8% 87.9%. Furthermore, lifetime samples at various shows increased adsorption due water molecules occupying active sites.

The energy and industrial sectors' most recent extraordinarily quick expansion has resulted in a substantial rise stationary CO2 sources. As result, many questions have been raised concerning how to stop global warming implement methods mitigate its effects by 2050 create low-carbon sustainable future. Over the last three decades, India's emissions increased at growth rate of 3.1 % mainly consumption fossil fuels. In this Indian situation, best method, besides renewable sources, is Carbon capture, utilization, storage (CCUS), which will make it possible achieve net-zero targets within century. Given this, brief review discussion that aims study development CCUS deployment importance for were conducted. highlights current scenario India world, increase trend, consequences globally. Furthermore, on present status several areas carbon (CCUS) technologies done. To clearly define maturity each important component system with commercialization direction route, we focused determining technological readiness level (TRL) from perspective. Further, identified data different sizes biggest R&D schemes, policies, regulations initiatives taken government across country. Lastly, our seeks provide guide successful implementation India.
