“…Therefore, $16–46/t-CO 2 can be added to the levelized cost of CO 2 capture (LCOC) values in Figures – if a more comprehensive cost is desired. The 45Q tax credit was also not considered in this analysis, but the tax credit can easily be included by reducing the LCOC values in Figures – by $35/t-CO 2 (for enhanced oil recovery use) or $50/t-CO 2 (for permanent storage) …”

Target properties of CO 2 capture adsorbents that would ensure economic viability of bioenergy with carbon capture and storage (BECCS) are defined. The key role of sorbent lifetime in the process cost is demonstrated, and an optimal heat of adsorption for BECCS is postulated through a balance of adsorbent–adsorbate affinity and regeneration energy demand. Using an exponential decay model of sorbent capacity increases the process cost and results in an optimum sorbent lifetime. To ensure a levelized cost of carbon below $100/tonne-CO 2 , adsorbents should be designed to have working capacities above 0.75 mol/kg, lifetimes over 2 years, heats of adsorption of approximately −40 kJ/mol, and exponential degradation decay constants below 5 × 10 –6 cycle –1 (equivalent to a half-life of 1.3 years). Our model predicts a BECCS process cost of $65/t-CO 2 can be achieved with a degradation-resistant adsorbent, $40/kg sorbent cost, 2.0 mol/kg working capacity, −40 kJ/mol heat of adsorption, and at least a 2 year lifetime.

“…Some indicates that there will be an increase in CCS capacity resulting primarily from utilization for enhanced oil recovery (EOR) in deference to that for immediate sequestration. 40 − 44 This increase is due to the additional revenue stream from selling the effluent for this purpose. Therefore, EGUs located near existing oil fields and CO 2 pipelines are more likely to be equipped with CCS.…”

Three of the main challenges in achieving rapid decarbonization of the electric power sector in the near term are getting to net-zero while maintaining grid reliability and minimizing cost. In this policy analysis, we evaluate the performance of a variety of generation strategies using this “triple objective” including nuclear, renewables with different energy storage options, and carbon-emitting generation with carbon capture and storage (CCS) and direct air capture and storage (DACS) technologies. Given the current U.S. tax credits for carbon sequestration under Section 45Q of the Internal Revenue Code, we find that two options: (1) cofiring bioenergy in existing coal-fired assets equipped with CCS, and (2) coupling existing natural gas combined-cycle plants equipped with CCS and DACS, robustly dominate other generation strategies across many assumptions and uncertainties. As a result, capacity-expansion modelers, planners, and policymakers should consider such combinations of carbon-constrained fossil-fuel and negative emissions technologies, together with modifications of the current national incentives, when designing the pathways to a carbon-free economy.

“…In order to model air quality and cope with heavy pollution days, one of the important tasks is monitoring emissions of major pollution sources, including industrial, agricultural, domestic, and mobile pollution. And emissions of these pollution sources should be monitored at a uniform interval, according to the Bulletin on the Second National Census of Pollution Sources released by China's Ministry of Ecology and the Environment [3,4].…”

In order to model air quality in heavy pollution days, a dynamic emission monitoring system is implemented in the Beijing road network, which requires the input of hourly traffic flows. Floating car data (FCD) is increasingly employed for flow estimation based on the fundamental diagrams to supplement data provided by stationary detectors. However, existing studies often used a typical fundamental diagram without considering the hysteresis phenomena and the uncertainty of traffic flow estimation. This study aims to develop a multiperiod fundamental diagram for the traffic flow estimation from FCD considering the hysteresis phenomena. The result shows that the proposed multiperiod fundamental diagram can improve the accuracy of flow estimation. The uncertainty of traffic flow estimation at both 10 minutes and 1 hour is also quantified, and the result indicates that the variation of the estimation uncertainty at 1 hour is lower than that at 10 minutes, with an average 7% reduction of the range of 95% confidence interval (CI). But there is no significant difference in magnitudes of the estimation uncertainty at 1 hour compared with that at 10 minutes. Moreover, the uncertainty for congested flows is lower than that for free flows. In the case study, the proposed model is employed to develop the spatial and temporal distributions of flows and emissions for the metropolitan area in Beijing.
