“…Saleh et al (2019) proposed a novel conceptual NGCC configuration integrated with a lithium-based PCC technology, which shows a reduction in its net efficiency equal to 9.2% points, being this value close to the energy penalty of the amine-based PCC technology published elsewhere (Sanchez Fernandez et al, 2014;Díaz-Herrera et al, 2021). Other studies reported the use of thermal solar energy to compensate for the energy penalty of the PCC plant (Li et al, 2012;Lambert et al, 2014;Wang et al, 2015;Liu et al, 2017;Shirmohammadi et al, 2021). A very interesting study on this subject is the one published by Zhai and co-workers (Zhai et al, 2018), who mentioned that a coal-fired power plant with a solar-assisted PCC plant shows a higher LCOE than the conventional PCC technology, mainly because of the increase in the CAPEX associated with the solar farm.…”

This work aims to analyze the cost projection of natural gas combined cycles (NGCC) with post-combustion carbon capture (PCC) technology for two promising power plant configurations, namely: conventional NGCC and exhaust gas recirculation (EGR). A thermo-economic analysis was performed considering the second-law efficiency for the CO2 separation process (η2nd) and the CO2 avoided cost (CAC) as main indicators. Several critical variables influencing the overall cost of the plant were considered, such as the work required for solvent regeneration (Wregen), technology maturity, learning rate, carbon tax credit, and carbon capture level (85%, 90%, and 95%). A hybrid method combining engineering-economic and experience-curve approaches was used to estimate the costs of Nth-of-a-kind (NOAK) plants. The results showed that NOAK plants could potentially decrease the levelized cost of electricity (LCOE) by 10%–11%, and the CAC by 21%–23%, compared with first-of-a-kind (FOAK) plants. EGR at 85% capture level showed the best economic performance among the study cases evaluated, with a CAC equal to $102.5/tCO2. At an 85% capture level, the CAC for the conventional NOAK NGCC plant is $104.1/tCO2; maintaining this same CAC value, the carbon capture rate could increase from 85% to 90.8% if EGR configuration is implemented. Finally, from the findings of this research, it is concluded that the CAC for NOAK plants is expected to be, in the best scenario, as low as $69/tCO2. Therefore, these plants might need at least a similar carbon tax value to ensure their operation during their useful life.

Solar thermal energy-assisted direct air capture (DAC) is widely considered as a novel carbon-negative technical route, innovatively enabling an effective removal of CO2 directly from ambient air. Here, we introduce an advanced concept that involves the conversion of CO2 captured by the solar thermal energy-assisted DAC into liquid methanol, simultaneously mitigating climate change and supplying green chemicals. This concept revolves around a well-considered integration of existing systems, and we emphasize key technologies for capturing, separating, and utilizing CO2 in this integrated system. Advances in Metal-Organic Frameworks (MOFs) based-DAC are reviewed, while the utilization of solar thermal energy further ensures the carbon-negative nature of DAC. Upcycling CO2 captured by DAC into value-added methanol adds both environmental benefits and economic feasibilities, which is also beneficial to achievinga circular carbon economy. The current status, ongoing developments, and anticipated future trends in this technology integration are timely addressed, the considerable application potential of integrated system is also comprehensively discussed.

“…In the studies of multi-agent decision-making in CCPP and renewable energy combined system, Refs. [22][23][24][25] taking CCPP as a flexible adjustment resource, established a combined optimization model of carbon capture unit, heat storage device, cascade hydropower stations, wind turbines, photovoltaic units, and other power resources. The results show that by flexibly adjusting the output of CCPP, the investment capacity of energy storage battery can be reduced, the utilization rate of renewable energy can be improved, and obvious emission reduction benefits and economic benefits can be obtained.…”

Increasing systematic carbon sinks and clean energy generation proportion are the main ways to reduce the carbon emission of power system. In order to promote wind power accommodation and reduce system carbon emissions, a cooperative operation model of wind turbine and carbon capture power plant (CCPP) is constructed. Then, the model is equivalently transformed into two sub-problems. One is the operation optimization sub-problem of cooperative alliance with the goal of maximizing the alliance benefit. The other is the benefit distribution sub-problem with the goal of fair distributing cooperative benefit. To protect participants’ privacy, the alternating direction method of multipliers (ADMM) is used to realize the distributed solution of the two sub-problems. Finally, the effectiveness of the proposed model is verified by an example, and the sensitivity analysis of the alliance benefit and system carbon emission is carried out with carbon price and carbon capture cost as the sensitivity factors. The example results show that: (1) By providing up and down regulation services to wind turbines, CCPP can obtain ancillary service income and help to reduce the declaration deviation of wind turbines, which can realize multi-win-win situation. (2) Carbon price affects both thermal power units and carbon capture equipment. So, compared with carbon costs, the carbon emissions and the alliance benefit are both more sensitive to carbon price. The model of the paper is constructed under the deviation punishment mechanism, and subsequent research can be expanded in combination with a more detailed imbalance settlement mechanism.
