Abstract:
Natural gas offers the distinct and unquestionable advantage as an alternative fuel and produces fewer emissions compared to other traditional fuels. Natural gas is becoming one of the most dominant fuels available worldwide. Our assessment of the CNG gas filling station and Natural Gas Vehicle is to point out the strong growth and demand in Beijing where the infrastructure is not fully established and supported. This paper suggests that growing acceptance and use of CNGs will greatly bring economic outcomes and environmental benefits. With encouraging migration from conventional vehicles to gas fueled vehicles, technology developments and engineering breakthroughs will help CNG gain deeper market penetration and widespread market acceptance. The establishment of chain refueling stations, and development of refueling infrastructure will strengthen the business for CNG by allowing for easy accessibility to refueling stations. The use of natural gas vehicles will facilitate energy security and energy diversity.

Abstract:
In this paper the influences of road and traffic conditions on fuel consumption and fuel costs of conventional diesel, parallel hybrid, and stoichiometric compressed natural gas buses in intercity bus service are analysed. Calculation of fuel consumption and fuel costs for these three different bus technologies was conducted for road network of the Republic of Serbia. Three scenarios were considered. The first scenario includes bus traffic volume carried out on the road network in 2014. The other two scenarios are characterized by the decrease i. e. increase of traffic volume by 20% with unchanged state of road infrastructure in comparison to the year 2014. Obtained results show that in intercity bus service the greatest influence on the fuel consumption of buses has operating speed of the bus, followed by terrain type on which buses operate. The impact of other factors (international roughness index, fluctuation of traffic volume by 20%, and correction factors of fuel consumption) is less pronounced. In various operating conditions the fuel cost savings per 100 km of compressed natural gas buses compared to diesel buses are in the range of ?8.84-12.16. These cost saving for hybrid buses compared to diesel buses are in the range of ?3.33-7.27.

Abstract:
To estimate accurately the emission rates of buses fueled with a liquefied natural gas (LNG) system, a method capturing the emission characteristics of LNG buses is proposed. In previous studies, vehicle specific power (VSP), a good indicator for instantaneous power demand on engines, has been mostly used in analyzing the emission characteristics of traditional vehicles such as passenger cars, diesel buses and heavy-duty trucks, with less effort on new energy buses, especially LNG buses. Based on the characteristic analyses in this study, it does not accurately describe the emission characteristics of LNG buses if the operating condition is classified only according to VSP. In this paper, we identify that the factors significantly affecting emissions are both speed and VSP using correlation analysis. Then a two-dimensional algorithm is proposed to divide operating conditions into several operating bins based on speed and VSP, and the validity of this method is verified by comparing the measured values of emissions between a training dataset and a test dataset. Based on the analysis of emission characteristics in two-dimensional operating bins, a regression model for estimating emission rates of LNG buses is established. The feasibility and accuracy of the model are validated by using a test dataset. The results indicate that all the relative errors between measured values and estimated values are within 16%, and the values of normalized mean square error (NMSE) are close to zero, indicating that the model established based on both speed and VSP can be applied to the estimation of LNG bus emissions.

Abstract:
Alternative fuels and technologies offer potential for reducing emissions in public transportation. These potentials were explored by determining emissions levels and fuel consumption from the U.S. transit bus fleet and comparison of hypothetical scenarios in which implementation of specific alternative fuels and technologies is considered. Impacts from current transit bus procurements were also evaluated. Emissions benefits above and beyond the natural course of transit bus procurements were examined for new diesel buses running on ULSD fuel, diesel-electric hybrid buses, gasoline-electric hybrid buses, compressed natural gas and biodiesel. According to the analysis, reductions in emissions of CO, NMHC, NOx, PM and CO2, as well as fuel consumption, may be attained, and diesel hybrid buses yield the largest reductions in CO2 emissions and are the only technology to reduce fuel consumption relative to the present fleet. Introducing diesel-electric hybrid buses in 15% of the U.S. transit bus fleet would reduce annual end-use emissions by nearly 1,800 tons of CO, 400 tons of NMHC, 4,400 tons of NOx, 200 tons of PM, 491,400 tons of CO2, and fuel consumption by 50.66 millions of diesel gallons.

Abstract:
The Mountain Hemlock (MH) zone includes all subalpine forests along British Columbia’s coast. It occurs at elevations where most precipitation falls as snow and the growing season is less than 4 months long. The zone includes the continuous forest of the forested subzones and the tree islands of the parkland subzones (Figure 1). Old-growth stands are populated by mountain hemlock, Pacific silver fir, and Alaska yellow-cedar, and are among the least-disturbed ecosystems in the world. Canopy trees grow slowly and are commonly older than 600 years, while some Alaska yellow-cedars may be up to 2000 years old. Early regeneration failures followed slashburning and the planting of unsuitable species. Currently, the most successful and feasible option for reforesting cutovers is natural regeneration with a mix of the three main tree species, but uncertainties remain about the temporal and spatial pattern of regeneration, changes in species composition, and the time required for stand establishment after cutting. Our study addressed these concerns by examining regeneration patterns on 6 sites that were clearcut 11-12 years prior to sampling and left to regenerate naturally. The sites were located at the lower limits of the zone in the Tetrahedron Range, near Sechelt, at elevations from 1060-1100m.

Abstract:
Energy consumption and its environmental impact are now among the most challenging problems in most developing cities. The common sources of energy used as the fuel in transportation sector include gasoline, diesel, natural gas, propane, biofuels, electricity, coal, and hydrogen. However, in Tanzania, diesel and gasoline are still the dominant source of energy used by public and private vehicles. We have experienced significant efforts of converting conventional vehicles (gasoline engines) to operate on Compressed Natural Gas (CNG) or on hybrid system (gasoline and natural gas) as an alternative source of energy in Tanzania. The CNG is considered as cleaner combustion energy used as a vehicular fuel alternative to gasoline or diesel. In this chapter, the amount of energy consumption from the fuel combustion, the impact of environmental health (toxicity gas emission), the cost of fuel used by the transit buses in terms of fuel energy consumption, and driving profile are discussed. The scope of this work is based on the total energy contained in the fuel only. The ability of the engine to transform the available energy from the fuel into useful work power (efficiency) is left to the designers and manufacturers.
