Centralised electricity production from winter cereals biomass grown under central-northern Spain conditions: Global warming and energy yield assessments

Global warming and energy yield evaluation of Spanish wheat straw electricity generation – A LCA that takes into account parameter uncertainty and variability

“…The average results presented in this article for the GWP assessment of wheat straw electricity (55 Mg CO 2 eq/TJe) were very similar to previously published results for winter cereals grown as dedicated energy crop for electricity generation in the Spanish province of Soria (52 Mg CO 2 eq/TJe) [4] and slightly higher than the ones obtained for Brassica Carinata (47 Mg CO 2 eq/TJe) cultivated also in Spain [65]. Upon comparing these values it should be borne in mind that the methodologies used and the burdens of these studies have some differences between them.…”

“…Bioenergy is intended to play a central role in the accomplishment of these objectives accounting for more than half of projected 2020 Europe's energy output [2]. Potential GHG reductions of different pathways to produce bioenergy from solid [3,4] and liquid [5][6][7][8] are being evaluated intensively [9]. Several studies suggest that lignocellulosic biomass sources for heat and electricity production may perform better in GHG assessments when compared with crops used as feedstock for first generation liquid biofuels [10][11][12][13].…”

“…Several studies suggest that lignocellulosic biomass sources for heat and electricity production may perform better in GHG assessments when compared with crops used as feedstock for first generation liquid biofuels [10][11][12][13]. Crop residues [14][15][16][17] and dedicated crops [3,4] can be used as source of lignocellulosic biomass for bioenergy whereas the first ones usually offer higher resource efficiency [2]. Furthermore, the use of dedicated energy plantations for bioenergy in Europe could produce indirect land use changes rising food prices in other countries.…”

Life-cycle assessment of electricity in Portugal

“…A significant number of studies have addressed the life-cycle (LC) environmental impacts associated with single electricity generation technologies (e.g. [9][10][11][12][13][14][15][16][17]) and electricity transmission and distribution (e.g. [18][19][20][21][22][23][24]).…”

Identification of Arable Marginal Lands under Rainfed Conditions for Bioenergy Purposes in Spain

“…Moreover, in the Singular and Strategic Project "On Cultivos", a series of trials were carried out with triticale over a period of 3 years in different provinces in eight autonomous communities in Spain, producing yields of whole biomass between 1.6 to 12.4 Mg dm ha −1 [51]. Field trials carried out in two locations for two years in Northern Spain, with three different varieties, showed yields between 4.60 and 7.84 Mg dm ha −1 for the province of Soria, and between 6.20 and 10.25 Mg dm ha −1 in the province of León [52]. In many cases these crops are adapted to poor soils, having adequate production in arable marginal land [6].…”
