The global object of the Lignocellulosic Ethanol Demonstration (LED) project is to design, construct and operate the first biofuel commercial facility in Europe using second generation technology, consisting on a lignocellulosic biomass to ethanol plant. The total lignocellulosic biomass input to the process is 522 dry tonne/day, resulting in an ethanol production of 50 MML/yr. In addition it will produce lignin and distiller biomass. The global strategy of the work plan in order to meet the targets consists of the following items:• Biomass supply plan development. Design of the procurement plan and business model for a non conventional harvesting/transportation concept will be carried out.• Basic design. Based on Abengoa Bioenergy’s know-how and experience after the design and construction of pilot and demo plant of York (Nebraska, US) and Babilafuente (Salamanca, Spain) respectively, and the operational experience in the York pilot facility, the specific basic engineering design for the facility will be developed.• Detailed engineering. Results on basic engineering will be further employed for the detailed engineering of equipment, piping, auxiliary systems, control & instrumentation, structures, supports, electrics and civil works.• Construction. Outputs from the previous phase will be materialized during the construction phase.• Commissioning and start-up. Once the facility construction is over, first proofs will be carried out for checking the smooth operation of each piece of equipment.• Fleet assays. The final ethanol will be tested in vehicles engines for demonstrating both the affinity of bioethanol and its effects in mixtures with petrol.• Research and Development for engineering validation. R&D activities associated with the lignocellulosic biomass to ethanol technology will be carried out. The project is coordinated by ABNT (Spain). Other participants: CCL and CDAPP (France), GRD (Switzerland) and TNO (The Netherlands)
