Potential Bioethanol Feedstock Availability Around Nine Locations in the Republic of Ireland

Abstract

Abstract:The Republic of Ireland, like many other countries is trying to diversify energy sources to counteract environmental, political and social concerns. Bioethanol from domestically grown agricultural crops is an indigenously produced alternative fuel that can potentially go towards meeting the goal of diversified energy supply. The Republic of Ireland's distribution of existing soils and agricultural land-uses limit arable crop land to around 10% of total agricultural area. Demand for land to produce arable crops is expected to decrease, which could open the opportunity for bioethanol production. Bioethanol production plants are required to be of a sufficient scale in order to compete economically with other fuel sources, it is important therefore to determine if enough land exists around potential ethanol plant locations to meet the potential demands for feedstock. This study determines, through the use of a developed GIS based model, the potential quantities of feedstock that is available in the hinterlands of nine locations in the Republic of Ireland. The results indicate that three locations can meet all its feedstock demands using indigenously grown sugarbeet, while only one location can meet its demands using a combination of indigenous wheat and straw as the two locally sourced feedstocks.

“…So on, butanol can be varied ratio to mix with gasoline more flexible. There are several routes for producing bioethanol and ABE from agricultural feedstocks (Cascone, 2008;Champagne, 2008;Deverell et al, 2009;Gholamhassan et al, 2009).…”

“…However, the prices and availability of food will ultimately be determined by supply constraints of crops (Kostka et al, 2009). Also, the impact of biofuel production will be minimized by improving conversion efficiency and performing detailed life cycle analysis studies (Torney et al, 2007;Deverell et al, 2009). This work does not intend to provide an answer to these important questions.…”
