“…[26]. The efficiency of carbon dioxide removal, the technological readiness level (TRL), the capital and operating expenses, and the capacity to store or utilize carbon dioxide are the main factors to be considered while adopting CCUS technology [27]. Developing large-scale carbon capture is not possible because the investment cost remains very high.…”

The energy demand has grown alongside increasing population growth globally. Unfortunately, the utilization of fossil fuels, especially coal, has dominated the energy sectors, including power generation. Fossil fuels have no place in the sustainability future due to the limitation of these resources and the potential environmental impacts that may arise. Therefore, the decarbonization of the electricity sector has recently become the world’s attention, including in Indonesia. This study discusses opportunities and challenges of decarbonization initiatives in the electricity sector by conducting traditional reviews of various publications from direct science databases and publications from official websites of other organizations relevant to the research context. The results discuss decarbonization options by replacing coal with renewable energy. Other initiatives are also investigated in this paper to provide alternative possibilities. The study indicated that each option has challenges that can affect the success of each program.

“…With the exception of KS-1, a proprietary sterically hindered amine, using amine solutions for carbon capture was found to be cost-prohibitive, mostly because of the high-energy requirements for amine regeneration, in addition to other drawbacks, such as amine decomposition into harmful chemicals, amine evaporation, oxidative degradation, and equipment corrosion . Hence, new technologies are being developed at an increasingly faster pace. − Among the most promising technologies is the adsorption of CO 2 over amine- and polyamine-supported porous materials. Over the past decade or so, the number of new and established companies with commercial or near commercial carbon capture processes from large point sources or directly from air, by supported amine materials, has grown significantly.…”

This work is a mechanistic study of the CO2 reaction with diamines under both dry and wet conditions. All protic α,ω-diamines R1H1N1-(CH2) n -N2H2R2, with n = 1–5 and R1 and R2 = H and/or CH3, were investigated. Depending on the nature of the diamine, the reaction was found to follow one of two concerted asynchronous reaction mechanisms with a zwitterion hidden intermediate. Both mechanisms involved two processes. The first process consisted of a nucleophilic attack of the nitrogen N1 of the first amine group on the carbon of CO2, accompanied by the transfer of a hydrogen atom H1 from N1 to the nitrogen N2 of the second amine group, leading to the formation of a carbamate zwitterion. The subsequent process corresponds to the transfer of a hydrogen atom H2 from the second amine group N2 to an oxygen atom of CO2, thus ending the reaction by the formation of carbamic acid. The structure of the zwitterion hidden intermediate was determined using the reactive internal reaction coordinates (RIRC), a reaction pathway visualization tool, consisting of a 3D representation of the potential energy versus the internuclear distances N2–H1 and N2–H2, which correspond to the bond being formed and the bond being broken, respectively. The life span of the transitory species, i.e., the zwitterion, was found to depend on the nature of the second amine group. For primary amines, the life span of the zwitterion was “short”, whereas for secondary amines, it was “long”. The corresponding mechanisms were termed the “early” and “late” asynchronous mechanism, respectively. Regardless of the mechanism, the activation barriers were found to decrease with the length of the carbon chain linking the two amine groups, with an asymptotic behavior from n = 4. Involvement of a water molecule generates a significant catalytic effect for diamines with short carbon chains (n < 4), whereas for longer chain diamines, water has a slightly adverse effect.

“…The global concern over climate change and the urgent need to mitigate greenhouse gas emissions have highlighted the importance of carbon capture and utilization (CCU) technologies. – CCU not only helps in reducing emissions of CO 2 (i.e., the major greenhouse gas) but also presents opportunities for the production of valuable chemicals and fuels simultaneously. ,, As such, the development of efficient CCU processes is critical in addressing the challenges of climate change and transitioning to a more sustainable future in chemical engineering. , …”

The urgent need to mitigate greenhouse gas emissions and combat climate change has driven research in carbon capture and utilization (CCU) technologies. Among these, calcium looping (CaL) has emerged as a prominent candidate for CO 2 capture. This study aimed to explore the novel integration of CaL with methane bireforming (BRM) using CaO-Ni/CeO 2 as dual-function material (DFM) and investigated the challenges and opportunities associated with the process. Implementing a calcium looping-bireforming (CaL-BRM) process revealed distinct differences compared to methane dry reforming (DRM). Notably, methane conversion occurred at higher temperatures, likely due to competition with the formation of Ca(OH) 2 . Meanwhile, the conversion of CO 2 was delayed, possibly because hydroxide species on the CaO surfaces hindered the availability of CO 2 for methane reforming. To address these challenges, Ni/CeO 2 and CaO-Ni/ CeO 2 catalysts were employed in conventional catalytic gas-phase BRM and methane steam reforming (SRM) reactions. The results demonstrated that the presence of CaO significantly influenced BRM efficiency due to the Ca(OH) 2 formation, as was evident by the results of the characterization on the postreaction catalysts and the parallel study of SRM. This study contributes valuable insights into the feasibility and potential of CaL-BRM, advancing the development of sustainable CCU technologies.
