“…Absolute values of cost estimate are not given here and those given elsewhere [17] should be viewed with caution as they are made to an accuracy of ±30%. Moreover, metal market and contract prices have been rising for two years and this will probably lead to a much higher cost for the power plant if based on 2007euro values but will probably not lead to significant change in differential comparisons between the different options.…”

This paper presents the results of technical and economic studies in order to evaluate, in the French context, the future production cost of electricity from IGCC coal power plants with CO 2 capture and the resulting cost per tonne of CO 2 avoided. The economic evaluation shows that the total cost of base load electricity produced in France by coal IGCC power plants with CO 2 capture could be increased by 39% for 'classical' IGCC and 28% for 'advanced' IGCC. The cost per tonne of avoided CO 2 is lower by 18% in 'advanced' IGCC relatively to 'classical' IGCC. The approach aimed to be as realistic as possible for the evaluation of the energy penalty due to the integration of CO 2 capture in IGCC power plants. Concerning the CO 2 capture, six physical and chemical absorption processes were modeled with the Aspen Plus TM software. After a selection based on energy performance three processes were selected and studied in detail: two physical processes based on methanol and Selexol TM solvents, and a chemical process using activated MDEA. For 'advanced' IGCC operating at high-pressure, only one physical process is assessed: methanol.

“…Hence, equipping power plants with CCS technology is only of interest when long-distance CO 2 transport is required. In both cases, CO 2 feedstock supply can be regarded as energy-intensive, rated at 13.1 ± 2.8 and 2.04 ± 0.26 kWh t CO 2 –1 km –1 for flue gas and purified CO 2 , respectively. ,,,, Hence, the use of power plants and carbon suppliers, appearing beneficial at first, from an environmental point of view, should thus be treated with caution for industrial-scale systems. Indeed, this energy-intensive delivery of CO 2 as upstream carbon feedstock was identified in this study, but ignored in other life-cycle studies .…”

“…Alternatively, flue gas CO 2 is first captured using CCS technology, resulting in a power plant electrical power output reduction of 18.2 ± 5.0%, − corresponding to, in the case of the natural gas power plant chosen for this study, 474 kWh t CO 2 –1 (at annual electrical power and CO 2 outputs of 204 GWh and 7.8 × 10 5 tonnes, respectively) . Subsequently, the concentrated CO 2 stream is transported to the site of microalgae cultivation, requiring 2.04 ± 0.26 kWh t CO 2 –1 km –1 . , A minor part of microalgae carbon demand is met by seawater dissolved inorganic carbon …”

In this century, biofuels will play an important role as fossil fuel alternatives. However, the long-term sustainability of large-scale biomass-based energy production chains is largely unknown. The current study evaluates the effect of nitrogen and phosphorus nutrient recovery on net energy ratio (NER) and land use, comparing a prospective industrial-scale microalgae production system with established maize agriculture. The functional unit was the delivery of 1.0 TWh of electrical energy using biomethane firing. Nutrient recovery was modeled by embedding anaerobic digestion (AD) as downstream processing step in the biomass production chains. The main finding was that maize-based biomethane electricity provision outperforms a prospective microalgae system in terms of NER, estimated at 4.9 and 3.2, respectively, when utilizing cogenerated heat. In the absence of external fossil fuel input, the renewable maize-and microalgae-based systems would require surface areas of 6.2 × 10 4 and 3.9 × 10 4 ha, respectively. Sustainability of microalgae-based biofuel production is not set by areal productivity or microalgal lipid content but rather by nutrient recovery, which is an important finding that requires prioritization in microalgae research.
