life cycle inventory and energy analysis of cassava based fuel ethanol in china
Journal of Cleaner Production, 2008Co-Authors: Rubo Leng, Chengtao Wang, Cheng Zhang, Du DaiAbstract:Abstract The Chinese government is developing biomass ethanol as one of its Automobile Fuels for energy security and environmental improvement reasons. The cassava is an alternative feedstock to produce this ethanol fuel. Its performance of environmental impacts and energy efficiency is the critical issue. Life cycle assessment has been used to identify and quantify the environment emissions, energy consumption and energy efficiency of the system throughout the life cycle. This study investigates the entire life cycle from cassava plantation, ethanol conversion, transport, Fuel ethanol blending and distribution to its end-use. Product system of cassava-based ethanol fuel is described and it is divided into six unit processes. The environmental impacts and energy consumption of each unit process are quantified and some of the potential effects are assessed.

A Life-Cycle Comparison of Alternative Automobile Fuels
2012Co-Authors: Heather Maclean, Lester B Lave, Rebecca Lankey, Satish JoshiAbstract:We examine the life cycles of gasoline, diesel, compressed natural gas (CNG), and ethanol (C2H5OH)-fueled internal combustion engine (ICE) Automobiles. Port and direct injection and spark and compression ignition engines are examined. We investigate diesel fuel from both petroleum and biosources as well as C2H5OH from corn, herbaceous bio-mass, and woody biomass. The baseline vehicle is a gasoline-fueled 1998 Ford Taurus. We optimize the other fuel/powertrain combinations for each specific fuel as a part of making the vehicles comparable to the baseline in terms of range, emissions level, and vehicle lifetime. Life-cycle calculations are done using the economic input-output life-cycle analysis (EIO-LCA) software; fuel cycles and vehicle end-of-life stages are based on published model results. We find that recent advances in gasoline vehicles, the low petroleum price, and the extensive gasoline infrastructure make it difficult for any alternative fuel to become commercially viable. The most attractive alternative fuel is compressed natural gas because it is less expensive than gasoline, has lower regulated pollutant and toxics emissions, produces less greenhouse gas (GHG) emissions, and is available in North America in large quantities. However, the bulk and weight of gas storage cylinders required for the vehicle to attain a range comparable to that of gasoline vehicles necessitates a redesign of the engine and chassis. Additional natural gas transportation and distribution infrastructure is required for large-scale use of natural gas for transportation. Diesel engines are extremely attractive in terms of energy efficiency, but expert judgment is divided on whether these engines will be able to meet strict emissions standards, even with reformulated fuel. The attractiveness of direct injection engines depends on their being able to meet strict emissions standards without losing their greater efficiency. BioFuels offer lower GHG emissions, are sustainable, and reduce the demand for imported Fuels. Fuels from food sources, such as biodiesel from soybeans and C2H5OH from corn, can be attractive only if the co-products are in high demand and if the fuel production does not diminish the food supply. C2H5OH from herbaceous or woody biomass could replace the gasoline burned in the light-duty fleet while supplying electricity as a co-product. While it costs more than gasoline, bioethanol would be attractive if the price of gasoline doubled, if significant reductions in GHG emissions were required, or if fuel economy regulations for gasoline vehicles were tightened.

Adopting Gas Automobile Fuels (LPG & CNG) into the Nigerian Transportation System
The International Institute for Science Technology and Education (IISTE), 2020Co-Authors: Adegoriola, Adewale E., Suleiman, Ibrahim MusaAbstract:This study investigates and proposes the use of gas Automobile Fuels (LPG & CNG) as transport fuel in Nigeria, by showing the policies and incentives that have been utilized by other countries and an analysis of the cost efficiency and environmental effect of the use of auto-gas Fuels. The use of CNG and LPG as auto fuel in Nigeria presents benefits with regards to efficiency and environmental friendliness will be highlighted in this research work with emphasis on the economic advantage. Demand for natural gas is likely to overtake other fossil Fuels due to its availability, accessibility, versatility and cleanliness. This research shows that adopting gas Automobile Fuels (LPG & CNG) as an automotive fuel has few barriers but in the long run is very viable in terms of emissions of Green-house gases to the environment and financially economical. From the study, we suggest that policies and incentives would be helpful for the implementation of auto-gas as a transport fuel with regards to fiscal and regulatory such as; excise-duty exemption or rebate, grants/tax credits for gas fueling vehicles conversion/acquisition, vehicle sales-tax exemption or income/profit tax credit and more. If Auto-gas for automotive fuel is considered and implemented in the Nigerian Transportation system, it will move the Nigerian fuel market from an inelastic feature to an elastic feature. Keywords: Gas, Automobile Fuels, Transportation System, Nigerian DOI: 10.7176/JESD/10-14-02 Publication date:July 31st 202
