“…Ammonia is more stable, less expensive, and less corrosive than other amines. 41 However, ammonia boils at −33 °C and has a high vapor pressure, leading to rapid loss of absorbent and deterioration of absorption capacity. Ammonia loss can be mitigated by absorption of CO 2 at low temperature, 42 but the absorption efficiency is compromised and the energy requirements for cooling decrease energy efficiency.…”

Technological and medical advances over the past few decades epitomize human capabilities. However, the increased life expectancies and concomitant land-use changes have significantly contributed to the release of ∼830 gigatons of CO2 into the atmosphere over the last three decades, an amount comparable to the prior two and a half centuries of CO2 emissions. The United Nations has adopted a pledge to achieve “net zero”, i.e., yearly removing as much CO2 from the atmosphere as the amount emitted due to human activities, by the year 2050. Attaining this goal will require a concerted effort by scientists, policy makers, and industries all around the globe. The development of novel materials on industrial scales to selectively remove CO2 from mixtures of gases makes it possible to mitigate CO2 emissions using a multipronged approach. Broadly, the CO2 present in the atmosphere can be captured using materials and processes for biological, chemical, and geological technologies that can sequester CO2 while also reducing our dependence on fossil-fuel reserves. In this review, we used the curated literature available in the CAS Content Collection to present a systematic analysis of the various approaches taken by scientists and industrialists to restore carbon balance in the environment. Our analysis highlights the latest trends alongside the associated challenges.

“…The current challenges for CCS in general, as mentioned by Al-Hamed and Dinser [48], are: (1) the large energy penalty due to a reduction in the overall efficiencies of power plants, which translates into high operation and maintenance costs; (2) a lack of technical expertise due to the unavailability of plants with CCS, except for chemical absorbent plants; and (3) incorrect public perceptions regarding the maturity of renewable energy sources and the consequent underestimation of the ability of CCS technologies. These general challenges are equally applicable to the shipping industry.…”

This review paper examines the key barriers to using green ammonia as an alternative fuel in maritime industry. A literature survey is performed based on research articles and grey literature, with the aim of discussing the technoeconomic problems with and benefits of ammonia and the relevant technologies. The limitations of ammonia as a maritime fuel and its supply chain, the expected percentage demand by 2030 and 2050, its economic performance compared to other shipping fuels such as hydrogen, and the current regulations that may impact ammonia as a maritime fuel are discussed. There are several key barriers to ammonia’s wide adoption: (1) High production costs, due to the high capital costs associated with ammonia’s supply chain; (2) availability, specifically the limited geographical locations available for ammonia bunkering; (3) the challenge of ramping up current ammonia production; and (4) the development of ammonia-specific regulations addressing issues such as toxicity, safety, and storage. The general challenges involved with blue ammonia are the large energy penalty and associated operational costs, and a lack of technical expertise on its use. Regardless of the origin, for ammonia to be truly zero-carbon its whole lifecycle must be considered—a key challenge that will aid in the debate about whether ammonia holds promise as a zero-carbon maritime fuel.

“…10,11 This is due to several factors, including the fact that this process is more energy efficient than cryogenic processes. 12 Moreover, it can capture CO 2 from highconcentration gas sources, such as flue gases, unlike adsorption processes. 12 In the chemical absorption process, CO 2 in the exhaust gas reacts with the CO 2 absorbent and then releases it after heat treatment.…”

This paper provides a techno-economic analysis of carbon capture technologies for coal-fired power plants, which are significant contributors to greenhouse gas emissions. The study evaluates the strengths and weaknesses of different technologies, including supercritical and ultrasupercritical power plants, as well as different capacities of 1000 MW, 800 MW, and 500 MW. The analysis focuses on amine-based postcombustion as a carbon capture system, which is widely used in industries. Additionally, the study compares the cost and performance of retrofitting existing power plants with carbon capture systems of varying ages. Finally, the analysis includes sensitivity and probabilistic uncertainty analyses to assess the impact of uncertainties on the results. The findings reveal that carbon capture is still necessary even in ultrasupercritical plants, and that the capacity factor has the greatest impact on the levelized cost of energy, while the discount rate has the lowest impact. The probabilistic uncertainty analysis indicates that deterministic estimates may underestimate the LCOE and carbon capture costs by up to 40%, underscoring the importance of considering uncertainties in decision-making processes.
