Electric vehicles (EVs) develop with high-speed in recent years. The automotive manufacturers recommend that battery will be replaced, when the remaining capacity reaches 80%. However, the capacity left in the battery can be used to support other fields, which requires lower performance. This paper attempts to analysis the feasibility of transportation battery second life used in communication base...
Many medium sized Italian cities present pollution problems, due to their geographical position and climate conditions and mainly due to congested traffic flows. Impacts on the health of residents are becoming more frequent and also risky. Thus different policies have been proposed to reduce environmental effects. Among these, the use of low or zero emission vehicles both for private and public transport...
Electrical demand continues to increase in both developing and developed countries. In Lebanon, the cost of electricity is relatively high because the utility burns expensive heavy fuel oil and gasoil in low-efficiency power plants. In addition, customers are using expensive private diesel generators to compensate for power shortages caused by the unreliable grid hence further escalating the energy...
This paper outlines the design of a prototype solar powered light-weight economically affordable clean car for the daily office commuters of Dhaka city. Calculation in this paper shows that the solar power alone will be sufficient to operate a light-weight car from one end of the capital city Dhaka, to the other, for a journey to and from the office. A preliminary design of the solar car has been...
Porównano ceny energii zawartej w różnych paliwach na podstawie cen paliw na początku 2012 r. Porównano także koszty energii uzyskanej z różnych paliw do wytwarzania ciepła i napędu pojazdów.
Government and industry are exploring approaches, such as technology (e.g. SESAR/NextGen) and market-based methods, to address the pervasive delays in the air transportation system. Resistance to some of the proposed market-based strategies are based on uncertainties of the societal and economic outcomes; specifically, there is a concern that fewer markets might be served, that service within existing...
Economic, technology and environmental incentives are changing the features of electricity generation and transmission. Centralized power systems are giving way to local scale distributed generations. At present, there is a need to assess the effects of large numbers of distributed generators and short-term storage in Microgrid. To accommodate the high demand of renewable energy and the environment...
The processes and routes of syngas production from biomass gasification were first outlined, and the key processes of this technology were highlighted in the paper. Simultaneously, the cost of syngas production from biomass gasification was evaluated to be RMB 1.05/Nm3 when the handling capacity of gasifier, material cost and system operating rate is separately fixed to be lton/h, RMB 250/ton and...
Industry strategists, government regulators, and the media have focused on addressing concerns over the performance of the air transportation system with respect to delays. One of the strategies proposed has been to limit the scheduled operations at an airport to a priori feasible capacity limits. This approach has been criticized on the basis that it would reduce the number of markets served and...
This paper discusses the advantages of using renewable energy sources in the architecture of an off-grid hybrid power system in rural areas. The studied system is composed of a diesel generator to which a micro hydropower plant is added. Simulations using the Hybrid Optimization Model for Electric Renewable (HOMER) are performed for given annual values of hydro resources, power demands and hybrid...
This paper presents the results of the application of model (developed in Part-I) and simulation algorithm (developed in Part-II) for determining the techno-economics of battery storage type hybrid energy system intended to supply the load demand of a rural remote area having a cluster of nine villages (grid isolated). The hour-by-hour simulation model is intended to simulate a typical one month period...
