a b s t r a c tThis paper discusses the overall energy consumption and greenhouse gas emissions when extracting pigments and producing hydrogen from Spirogyra sp. microalga biomass. The energy evaluation from the biomass leftovers was also included in this work. The influence of the functional unit and different allocation criteria on the biorefinery assessments is also shown. The study consists of laboratory tests showing Spirogyra sp. growth, harvesting, drying, pigment extraction and fermentation by Clostridium butyricum. Electrocoagulation and solar drying were tested and compared to conventional centrifugation and electrical dewatering in terms of their energy consumption for harvesting and dewatering, respectively. To discuss the biorefinery viability, the pigments and biohydrogen (bioH 2 ) retail costs are considered against operational costs according to electricity needs. The low yield of biochemical hydrogen and the high energy requirements for the pigment extraction were identified as main topics for further research. This research hopefully contributes to highlight the importance of energy and emission balances in order to decide on feasibility of the biorefinery.

“…001 used brewery wastewater (Seifert, Waligorska, & Laniecki, 2010). Because several different feedstocks such as organic waste and algal biomass are used, both photofermentation and dark fermentation are considered to have potential advantages (Ferreira, Ribau, & Silva, 2011;Yang, Guo, Xu, Fan, & Luo, 2011). Similarly, the highest production of H 2 was produced using pretreated biomass of microalgae Nannochloropsis sp.…”

“…The life cycle analysis (LCA) of a vehicle emerges as an important tool not only to evaluate the efficiency of the vehicle but also its environmental impact at a local and "global" level. The use of LCA has been used in a large number of studies to compare vehicle technologies and alternative fuels [26][27][28][29]. A review of LCA use in vehicle analysis is well expressed in [30], which highlights important aspects to take into account when structuring a LCA study.…”

Taxi Fleet Renewal in Cities with Improved Hybrid Powertrains: Life Cycle and Sensitivity Analysis in Lisbon Case Study

2015

Stringent emissions regulations in cities and the high amount of daily miles driven by taxi vehicles enforce the need to renew these fleets with more efficient and cleaner technologies. Hybrid vehicles are potential candidates due to their enhanced powertrain, and slower battery depletion and fewer lifetime issues, relative to full electric vehicles. This paper proposes a methodology to analyze the best theoretical hybrid powertrain candidate with maximum in-use efficiency, minimum life cycle greenhouse gas emissions, and minimum additional cost, for a Lisbon taxi fleet case study. A multi-objective genetic algorithm integrated with a vehicle simulator is used to achieve several trade-off optimal solutions for different driving patterns. Potential improvements in taxi carbon footprint are discussed as a function of its lifetime, urban/extra-urban driving and maintenance/fuel life cycle uncertainty. Hybrid powertrains reveal to be advantageous comparatively to the conventional vehicle, especially in urban conditions. Specifically optimized solutions could reduce in-use energy consumption by 43%-47% in urban driving, and 27%-34% in extra-urban driving conditions, and reduce life cycle emissions by 47%-49% and 34%-36% respectively, relative to the conventional taxi. A financial gain of 50 $/km/fleet in extra-urban and 226 $/km/fleet in urban routes could be achieved by replacing the taxi fleet with the optimal solutions. OPEN ACCESSEnergies 2015, 8 9510
