Overall structure of electrical power system is in the process of changing. For incremental growth, it is moving away from fossil fuels major source of energy in the world today to renewable energy resources that are more environmentally friendly and sustainable [1]. Factors forcing these considerations are (a) the increasing demand for electric power by both developed and developing countries,...

Approach • Determine the cost and availability of the three candidate biomass feedstocks. • Design a process scheme for the production of hydrogen. • Determine optimal hydrogen production through the testing of various simulation cases. • Analyze research and simulation results to determine technical and economic feasibility. • Determine the commercialization barriers to the production of hydro...

The paper contributes to techno-economic modelling of CO2 capture process in coalfired power plants. Technological options of CO2 capture have been chosen and cost estimation relationships (CERs) for the chosen options provided. The CERs are being fitted into a developed overall model of carbon capture and sequestration. Functions relating capital costs, operation and maintenance costs and tota...

Lignocellulosic ethanol is expected to be commercialised during the next decade as renewable energy for transport. Competiveness with first generation bioethanol and with gasoline is commonly considered in techno-economic analyses for commercial stage. Several existing reviews conclude about the high spread of current and projected production costs of lignocellulosic ethanol due to the signific...

A large body of economic research has shown the strong correlation between broadband connectivity and economic productivity (e.g., [1–3]). These findings motivate government agencies such as the FCC in the US to provide incentives to services providers to deploy broadband infrastructure in unserved or underserved areas. In this paper, we describe a framework for identifying target areas for net...

A techno-economic model was developed to investigate the influence of components on the system costs of redox flow batteries. Sensitivity analyses were carried out based on an example of a 10 kW/120 kWh vanadium redox flow battery system, and the costs of the individual components were analyzed. Particular consideration was given to the influence of the material costs and resistances of bipolar...

In this study, solar water heater was investigated using meteorological and geographical data of 129 sites over Turkey. Three different collector types were compared in terms of absorber material (copper, galvanized sheet and selective absorber). Energy requirement for water heating, collector performances, and economical indicators were calculated with formulations using observed data. Results...

A multitude of Internet protocols are developed in the Internet Engineering Task Force to solve the challenges with the existing protocols and to fulfill the requirements of emerging application areas. However, most of them fail to achieve their goals due to limited adoption. A significant reason for non-adoption seems to be that the potential adopters’ incentives for adoption are not understoo...

Techno-economical studies in telecommunication networks are important and quite complicated topics. One of the major challenges is to estimate the investment in new or additional network equipment to consider a new service, or to compare two technologies in the same or different frequency band. In order to carry out this kind of analysis, a nationwide network design and dimensioning study has t...

The software package SELBESTTRA offers a choice of the best transportation systems of mineral resources with technical, economic and ecological point of view. By entering of parameters of production and the parameters of the proposed transportation route, the software gives us the best solution regarding the protection of environment through which transport is carried out and that for the best ...
