Book Description
Inhaltsangabe:Introduction: Transport is a key factor in modern economies. There are an estimated 31.5 million road goods vehicles running on Europe s motorways each year, which are coping with a steadily increasing amount of goods transported. Although these vehicles are crucial to guarantee the ubiquitous goods availability we are used to, and to assure the flexibility of European industry, they are also part of mankind s most pressing current problems. For instance, the emission of greenhouse gases, i.e. carbon dioxide (CO2), methane (CH4), nitrous oxide (NO2), hydrofluorocarbons (HFC), perfluorocarbons (PFC) and sulphur hexafluoride (SF6), due to fuel combustion in goods transport constitutes about 20 per cent of overall greenhouse gas emission and is only outnumbered by emissions of the energy industry. Overall decrease of these contaminants shall be, of course, one of the main objectives in the long-term, but in particular within urban agglomerations it is also of great interest to decrease local emission levels as a first sep. Changing over to less carbon-intensive fuels can reduce local carbon dioxide and other emissions, even if the well-to-wheel emission level does not improve notably. Apart from the emission problem, nearly 99% of the overall fuel consumption in transport is provided by fossil fuels and therefore competing for the finite crude oil resources with other industries, in particular the energy industry. There are many different forecasts of how long world s oil reserves will last, but independently of these estimations it is undeniable that they will end sometime. Hence, it is the second vital transport-related challenge to make it independent from fossil energy resources by developing and introducing renewable fuels, complying technologies to run them and a reliable infrastructure to distribute them. Although there are still many problems to solve regarding technical issues, many viable solutions for running vehicles by other means than diesel and gasoline are already available. However, the biggest problem seems to be the distribution. Since vehicles and fueling infrastructure are complementarities, most customers do not use these vehicles because they can not refill them properly, and fuel companies do not introduce new fuel stations due to a lack of customers, that would use them. Consequently the main challenge currently is to break through this chicken-egg problem and build up a fuel distribution network, which [...]

Book Description
"TRB's Airport Cooperative Research Program (ACRP) Report 83: Assessing Opportunities for Alternative Fuel Distribution Programs consists of a guidebook and toolkit designed to help airports introduce and market alternative fuels to their airport community that includes tenants and consumers off airport. Alternative fuels considered include alternative jet fuel, green diesel, biodiesel, ethanol, compressed natural gas (CNG), liquefied petroleum gas (LPG), and electricity. The guidebook includes a step-by-step process to evaluate opportunities and constraints for alternative fuel distribution programs."--Publisher's description.

Book Description
This document describes a study done for the U.S. Army Combined Arms Support Command (CASCOM) to assess future needs for temporary petroleum pipeline structure. At the time this work was begun, the Army was weighing further development of a new pipeline capability, the Rapidly Installed Fuel Transfer System (RIFTS), and also conducting its normal cycle of future force structure planning. This project reviewed historical uses of temporary pipelines and surveyed future scenarios in order to develop a broad list of potential pipeline requirements. Next, against this list of likely requirements, the performance of several fuel distribution options -- including existing and planned pipeline units and equipment, new pipeline options, and the use of trucks -- was assessed across a variety of performance dimensions. The analytic results pointed to no clearly best choice. Instead, the preferred course of action is very sensitive to the decisionmaker's assessment of the environment and weighting among the importance of the different performance dimensions. A decision-support table to help the decisionmaker with this assessment is provided along with supplementary recommendations on near-term investment of reset funds and the reallocation of personnel within existing petroleum pipeline unit designs. The findings in this document should be of interest to those engaged with future Army logistics support force structure requirements.
