Techno-economic analysis for the synthesis of liquid and gaseous fuels based on hydrogen production via electrolysis

Simulation-Based Analysis of the Potential of Alternative Fuels towards Reducing CO2 Emissions from Aviation

“…Economies of scale S(t) depend upon the ratio of the initial production capacity PC REF (t), which is taken as a reference value, the current production capacity PC(t), and the degression exponent n, which aggregates effects due to capital costs, learning, and plant operation and depends on the used technology [13,14].…”

“…Electrofuels are a promising alternative to resolve these issues since they only rely on renewable electricity, water, and CO 2 that can be obtained from concentrated sources or extracted from the air as main constituents. Over the entire life cycle, the CO 2 mitigation potential of electrofuels from renewable electricity and CO 2 is estimated to range between 70% and 87% compared to petroleum-derived fuels [8,[12][13][14].…”

Methanol and dimethyl ether from renewable hydrogen and carbon dioxide: Alternative fuels production and life-cycle assessment

“…The products of carbon dioxide hydrogenation can include; hydrocarbon fuels, formamides, carboxylic acids, methanol and more (Jessop et al, 2004;Gnanamani et al, 2015;Jadhav et al, 2014). Due to its low production costs, well established infrastructure and advanced processing technology, methanol is an ideal candidate for the conversion of CO 2 with H 2 (Tremel et al, 2015). Our previous work proposed a method of producing methanol from renewably derived H 2 and CO 2 (Matzen et al, 2015).…”

The Potential for Electrofuels Production in Sweden Utilizing Fossil and Biogenic CO2 Point Sources

“…CO2 can be captured from various industrial sources with costs ranging from about 10€2015 to 170€2015/ton CO2, depending on the CO2 concentration (Damen et al, 2006(Damen et al, , 2007Finkenrath, 2011;Goeppert et al, 2012;Kuramochi et al, 2012Kuramochi et al, , 2013IEA, 2013; see text footnote 1). This indicates that from an economic point Mohseni (2012), Grond et al (2013), Schiebahn et al (2015), and Tremel et al (2015).…”

“…This can be compared to the CO2 capture cost linked to processes requiring an extra purification step like steel and iron, ammonia, refinery, cement, and fossil or biomass combustion plants estimated at 20€2015-170€2015/ ton CO2 in the short term (10-15 years) and 10€2015-100€2015/ton CO2 in the more long term (Damen et al, 2007;Finkenrath, 2011;Kuramochi et al, 2012Kuramochi et al, , 2013IEA, 2013). Even though it has been indicated that the cost for carbon capture represents a relatively modest share (a few percent) of the total electrofuel-production cost unless air capture is assumed (Graves et al, 2011;Tremel et al, 2015;Varone and Ferrari, 2015; see text footnote 1), using CO2 from biofuel production represent an attractive source for electrofuel production since more pure streams will likely be used first for economic reasons and the domestic biofuel actors, representing a considerable biofuel production capacity, in order to comply with sustainability requirements need to improve their production processes in terms of CO2 emissions. Table 1 presents the type of CO2 stream, typical concentration of CO2, the range of CO2 emissions per unit, and the amount of recoverable CO2, for different point sources.…”
