“…In addition to driving conditions, the thermal efficiency of vehicle engines has a fundamental impact on GHG emissions. Numerous articles have discussed the efficiency of buses and taxis, including those fitted with gas engines (Tarroja et al 2015;Wegrzyn et al 1999;Chandler et al 2000;Beer et al 2002;Graham et al 2008;Nijboer 2010;Ou et al 2010;Karakurt et al 2011;Zhang et al 2014;Wang et al 2015;Jaffe et al 2015). Table 4 summarizes the fuel consumption rate and provides GHG estimates for buses and taxis.…”

This paper employs a review of the technical literature to estimate the potential decrease in greenhouse gas (GHG) emissions that could be achieved by increasing the application of gas engines in China in three sectors: urban public transport vehicle; shipping; and thermal power plants. China's gas engine development strategies and three types of gas resource are discussed in the study, which indicates that gas engines could decrease GHG emissions by 520 megatonnes (Mt) of carbon dioxide equivalent (CO 2e ) by 2020. This would account for 9.7 % of the government's target for decreasing GHG emissions and is dominated by methane recovery from the use of coal mine gas (CMG) and landfill gas (LFG) for power generation. In the public urban transport vehicle and shipping sectors the low price of natural gas and the increasing demand for the control of harmful emissions could spur the rapid uptake of gas engine vehicles. However, the development of CMG-and LFG-fuelled power plants has been limited by the unwillingness of local enterprises to invest in high-performance gas engine generators and the associated infrastructure. Therefore, further compulsory policies that promote CMG use and LFG recovery should be implemented. Moreover, strict regulations on limiting methane leakage during the production and distribution of gas fuels are urgently needed in China to prevent leakage causing GHG emissions and largely negating the climate benefits of fuel substitution. Strategies for increasing the application of gas engines, promoting gas resources and recovering methane in China are instrumental in global GHG mitigation strategies.

“…This is due to the limitation on the size of the on‐board CNG cylinders and the availability of NG fuelling stations. Alternatively, liquefied NG provides a much higher fuel carrying capacity (Wegrzyn et al , 1999). The technology for liquefying NG is being established in Egypt for exportation reasons.…”

PurposeThe objective of this paper is to evaluate the potential sustainable transportation strategies for Cairo in terms of their impact on emissions over the next ten years. The considered strategies include using cleaner fuel, implementing inspection and maintenance programs and adopting emission standards for new vehicles.Design/methodology/approachThe strategies were evaluated in terms of the expected reductions of particulate matter (PM) and ozone precursors due to the future implementation. Emissions were estimated utilizing a mix of the relevant national and international. Accordingly, a three‐phase integrated strategy is recommended, considering the local technical and institutional aspects.FindingsIn case of no actions taken, emissions of PM and ozone precursors could increase at the year 2013 by 95 and 50 percent, respectively. Implementing the proposed integrated strategy could result in reducing the emissions of PM and ozone precursors by about 53 and 49 percent, respectively.Practical implicationsThe proposed strategy is applicable because the targets are set considering the local aspects. However, the estimated emission reductions could almost compensate for the increase in the fleet size over the time. Therefore, achieving real reductions of emissions requires additional strategies to be considered.Originality/valueOwing to the lack of local emission factors and measurements, this original work highlights the expected impacts of the potential strategies for controlling vehicle emissions in Cairo. Also, the findings indicate the need to consider other additional strategies in the long term planning process.

“…In order to meet the growing needs of the trucking industry and stricter clean air requirements, the Department of Energy -Office of Heavy Vehicle Technologies (DOE-OHVT) has undertaken an R&D program to develop fuel efficient, low-emissions trucks. Under the Natural Gas Vehicle Systems Program support is provided in developing liquefied natural gas technologies in the areas of production, storage tanks and refueling systems [1,2]. Specific program goals include the following: (1) eliminating evaporative greenhouse gas emissions; (2) recovering 25% of the energy of liquefying and transporting natural gas; and (3) increasing onboard fuel storage capacity by 40% for compressed natural gas (CNG) and 25% for LNG.…”

Liquefied natural gas (LNG) is being developed as a heavy vehicle fuel. The reason for developing LNG is to reduce our dependency on imported oil by eliminating technical and costs barriers associated with its usage. The U.S. Department of Energy (DOE) has a program, currently in its third year, to develop and advance costeffective technologies for operating and refueling natural gas-fueled heavy vehicles (Class 7-8 trucks).The objectives of the DOE Natural Gas Vehicle Systems Program are to achieve market penetration by reducing vehicle conversion and fuel costs, to increase consumer acceptance by improving the reliability and efficiency, and to improve air quality by reducing tailpipe emissions. One way to reduce fuel costs is to develop new supplies of cheap natural gas. Significant progress is being made towards developing more energy-efficient, low-cost, small-scale natural gas liquefiers for exploiting alternative sources of natural gas such as from landfill and remote gas sites. In particular, the DOE program provides funds for research and development in the areas of; natural gas clean up, LNG production, advanced vehicle onboard storage tanks, improved fuel delivery systems and LNG market strategies. In general, the program seeks to integrate the individual components being developed into complete systems, and then demonstrate the technology to establish technical and economic feasibility. The paper also reviews the importance of cryogenics in designing LNG fuel delivery systems.
