On-Site Ethanol in Gasoline Blend Analysis Saves Money and Eliminates Uncertainty in Fuel Blends
The use of ethanol as a gasoline additive has increased dramatically over the past few years and will likely continue to increase. For fuel blenders, this means an added challenge to avoid an incorrect blend that could lead to regulatory fines, loss of customer confidence and damage to equipment. A quick on-site analysis with a portable mid-infrared based analyzer, such as the Wilks InfraCal ...

Causal relationship between fossil fuel consumption and economic growth in the world
Fossil fuels are major sources of energy, and have several advantages over other primary energy sources. Without extensive dependence on fossil fuels, it is questionable whether our economic prosperity can continue. This paper analyses cointegration and causality between fossil fuel consumption and economic growth in the world over the period 1971 to 2008. The estimation results indicate that ...

Second law analyses on oxy-fuel combustion of gaseous fuels
The exergy losses in the adiabatic premixed oxy-fuel combustion are quantitatively analysed. The global exergy loss decreases with increasing equivalence ratio. The exergy loss of chemical reaction is comparable to that of internal thermal energy exchange for low equivalence ratio while that of mixing process is negligible. To keep similar thermodynamic characteristics of conventional combustion, ...

Effects of varying air-fuel ratio on the performance of a theoretical Diesel cycle
This paper analyses the effects of varying air-fuel ratio on the performance of a theoretical Diesel cycle under a temperature restriction as maximum. Amount of heat addition at constant pressure is defined as a function of fuel's energy with utilising the combustion efficiency. The amount of released energy into the cylinder restricts the compression ratio. Relations between the combustion ...

Sample Preparation for Refuse Derived Fuels
Plastic, wood and shredded waste, are in times of rising crude oil prices very interesting additions to the classic fuels. Especially in the cement industry, the energy rich fractions from conditioning processes are readily burned along. Important here is the analytical evaluation of the materials. Refuse derived fuels: Plastic, wood and shredded waste: Here are some examples of more or less well ...

Thermodynamic modelling of a proton exchange membrane fuel cell
This paper presents the thermodynamic modelling of a proton exchange membrane (PEM) fuel cell at various operating conditions through energy and exergy analyses. In addition, the correlations and equations available in literature were used to determine thermodynamic irreversibilities in the PEM fuel cell at different operating conditions such as cell temperature, pressures of anode and cathode, ...

Development of spherical isotropic power reactor design for enhancement of safety and economics in power production
Following the civilian design development trend of Nuclear Power Plants (NPPs), a newly introduced NPP has been investigated. The conceptual study for isotropic power production is done by the water-cooled reactor. A new design of core geometry can improve the safety and economics of power production. The newly designed Spherical Isotropic Power Reactor (SIPR) has been analysed. The configuration ...

Hydrogen as transport fuel in Iceland. The political, technological and commercial story of ECTOS
Through the political, the technological and the commercial story of the early phases of the ECTOS project and its background, the implementation of hydrogen as transport fuel in Iceland is analysed. The presence of large amounts of geothermal energy is the resource basis for the governmental plans for converting Iceland into a hydrogen economy. Strong political commitment has established the ...

Energy and exergy analyses of a CI engine fuelled with palm biodiesel based on experimental data
Only energy analysis is not enough to define the best efficiencies of any system, so exergy analysis uses to understand and improve the actual efficiencies of the whole system. Energy analysis identified the energy losses but could neither identify the irreversible losses nor their location. These are, however, could be clearly explained with the application of exergy analysis. In this study both ...

Nodal prices in an integrated energy system
This paper presents a multiperiod generalised network flow model used to analyse the economic interdependencies of integrated energy systems comprising the electric network and the various fuel supply and delivery systems in a medium term operational time frame. By using a network flow programming model, one can take advantage of much faster solution procedures than standard linear programming ...

EU fuel quality monitoring — 2014
Each year, under the requirements of the European Union (EU) Fuel Quality Directive (FQD) (1), EU Member States must report various types of information relating to the quality of petrol and diesel fuels sold in their territories. More specifically, Member States must sample fuels each year and analyse their technical characteristics to ensure that they are consistent with the requirements of the ...

The role of nuclear energy in the post-Kyoto carbon mitigation strategies
Policy scenarios examined in this paper provide insights into the long-term role that nuclear power could play in abating CO2 emissions. Impacts are quantified for a strict phase-out of nuclear generation capacities, and are contrasted with scenarios allowing for a nuclear technology breakthrough under a specific carbon-tax regime. The energy-related global CO2 emissions are reduced by nearly 50% ...

Energy efficiency indicators for public electricity production from fossil fuels
Electricity production is responsible for 32% of total global fossil fuel use, accounting for 132 EJ, and 41%, or 10.9 Gt of energy-related CO2 emissions. Improving the efficiency of electricity production therefore offers economic benefits and a significant opportunity for reducing dependence on fossil fuels, which helps to combat climate change and improve energy security. A set of indicators ...

Fuel cells - the environmentally friendly energy converter and power generator
Heat engines based on fossil fuel combustion produce harmful pollutant emissions. Environmental concerns and sustainable development call for new technology for energy conversion and power generation, which is more efficient, environmentally friendly and compatible with alternative fuels and renewable energy sources and carriers. Fuel cells meet all these requirements and are being rapidly ...

Biogas as an option for industrial applications
Biogas is typically burned to produce electricity or used as vehicle fuel. This case study analyses possibilities to utilise biogas directly in industrial applications to replace current fossil raw materials. True industrial cases are analysed by considering economic impacts of using either landfill gas or gas produced from biomass. Utilisation of biogas is economically viable and technically ...

Key Objectives in Modern Fuel Cell Studies
What are Fuel Cells? Fuel cells use the chemical energy of hydrogen or an alternative fuel to cleanly and efficiently produce electricity. Using hydrogen as the fuel only produces water, heat, and electricity. Hydrogen (the fuel) is supplied continuously, unlike in a battery, and a dynamic equilibrium is maintained. ...

Exergy analysis of a steam power plant: a case study in Iran
In the last decades, exergy analysis, based on the second law of thermodynamics was a method that substituted the energy analysis in studying thermodynamic systems. In this paper, the cycle of a power plant and its details, with two kinds of fuels, natural gas and diesel, have been analysed at its maximum load and the two factors, losses and exergy efficiency, which are the basic factors used to ...
