“…Its application to commercial size power plants has only been studied in terms of the power plant performance and economic analysis (e.g. Booras and Smelser, 1991;Desideri and Paolucci, 1999;Singh et al, 2003;Davison, 2007;Rubin et al, 2007;Lucquiaud and Gibbins, 2011). CO 2 capture process technologies for power plant can be divided into three general process routes (see In the post-combustion process, CO 2 is captured from the exiting flue gas, while in oxy-fuel combustion air is replaced by oxygen in the combustion process producing concentrated CO 2 .…”

“…According to Desideri and Paolucci (1999), the addition of CO 2 capture process to reduce 90% CO 2 emissions from a conventional power plant is penalized by high capital cost of the removal plant and the cost of electricity more than doubles at optimal absorber and stripper performance parameters. Singh et al (2003) found that the CO 2 capture cost using MEA scrubbing process is $55/ton of CO 2 avoided, which translates into 3.3 ¢/kWh and represents an increase of 30% in electricity price. Singh et al (2003) reported that thermal energy requirement to regenerate MEA solvents contribute a major part of the process overall annual cost.…”

“…As mention above, the reboiler heat duty in the regeneration column is the main energy consumer in amine scrubbing process for CO 2 capture (Desideri and Paolucci, 1999;Singh et al, 2003). The overall energy efficiency of CO 2 capture can be substantially improved by reducing this energy demand.…”

“…Cost estimates for retrofitting existing coal-fired power plants with postcombustion carbon capture technologies range from $35 to $55 per ton of CO2 mitigated (9)(10)(11)(12)(13)(14). Repowering (replacing coal combustion with coal gasification for precombustion carbon capture) is estimated to cost between $18 and $90 per ton CO2 (10,12).…”

We update a previously presented Linear Programming (LP) methodology for estimating state level costs for reducing CO 2 emissions from existing coal-fired power plants by cofiring switchgrass, a biomass energy crop, and coal. This paper presents national level results of applying the methodology to the entire portion of the United States in which switchgrass could be grown without irrigation. We present incremental switchgrass and coal cofiring carbon cost of mitigation curves along with a presentation of regionally specific cofiring economics and policy issues. The results show that cofiring 189 million dry short tons of switchgrass with coal in the existing U.S. coal-fired electricity generation fleet can mitigate approximately 256 million short tons of carbon-dioxide (CO 2 ) per year, representing a 9% reduction of 2005 electricity sector CO 2 emissions. Total marginal costs, including capital, labor, feedstock, and transportation, range from $20 to $86/ton CO 2 mitigated, with average costs ranging from $20 to $45/ton. If some existing power plants upgrade to boilers designed for combusting switchgrass, an additional 54 million tons of switchgrass can be cofired. In this case, total marginal costs range from $26 to $100/ton CO 2 mitigated, with average costs ranging from $20 to $60/ton. Costs for states east of the Mississippi River are largely unaffected by boiler replacement; Atlantic seaboard states represent the lowest cofiring cost of carbon mitigation. The central plains states west of the Mississippi River are most affected by the boiler replacement option and, in general, go from one of the lowest cofiring cost of carbon mitigation regions to the highest. We explain the variation in transportation expenses and highlight regional cost of mitigation variations as transportation overwhelms other cofiring costs.

Integrating Algae with Bioenergy Carbon Capture and Storage (ABECCS) Increases Sustainability

et al. 2018

Bioenergy carbon capture and storage (BECCS) has been proposed to reduce atmospheric CO2 concentrations, but concerns remain about competition for arable land and freshwater. The synergistic integration of algae production, which does not require arable land or freshwater, with BECCS (called “ABECCS”) can reduce CO2 emissions without competing with agriculture. This study presents a technoeconomic and life‐cycle assessment for colocating a 121‐ha algae facility with a 2,680‐ha eucalyptus forest for BECCS. The eucalyptus biomass fuels combined heat and power (CHP) generation with subsequent amine‐based carbon capture and storage (CCS). A portion of the captured CO2 is used for growing algae and the remainder is sequestered. Biomass combustion supplies CO2, heat, and electricity, thus increasing the range of sites suitable for algae cultivation. Economic, energetic, and environmental impacts are considered. The system yields as much protein as soybeans while generating 61.5 TJ of electricity and sequestering 29,600 t of CO2 per year. More energy is generated than consumed and the freshwater footprint is roughly equal to that for soybeans. Financial break‐even is achieved for product value combinations that include 1) algal biomass sold for $1,400/t (fishmeal replacement) with a $68/t carbon credit and 2) algal biomass sold for $600/t (soymeal replacement) with a $278/t carbon credit. Sensitivity analysis shows significant reductions to the cost of carbon sequestration are possible. The ABECCS system represents a unique technology for negative emissions without reducing protein production or increasing water demand, and should therefore be included in the suite of technologies being considered to address global sustainability.
