Coal sorption characteristics and coal surface tension
Underground coal mining in the Bulli Seam of Sydney Basin, Australia encounters the problems of coal and gas outburst as the coal contains high concentration of CO 2 , where certain parts of the seam have been found to be especially hard-to-drain. In order to better understand these problems, the influence of temperature and moisture on sorption capacity of bituminous coal was investigated at ...

Inquiry into coal seam gas
Poorly planned or managed coal seam gas (CSG) exploration or extraction activities pose considerable risks to both groundwater and surface water systems. Key water quality issues, from my own perspective, are listed below. Specific issues may be of greater or lesser significance for particular projects, but all of these issues should be thoroughly and transparently assessed for all proposed (or ...

Linkages among the US energy futures markets
This study investigates the price linkage among the US major energy sources, considering structural breaks in time series, to provide information for diversifying the US energy sources. We find that only a weak linkage sustains among crude oil, gasoline, heating oil, coal, natural gas, uranium and ethanol futures prices. This implies that the US major energy source markets are not integrated as ...

The global energy industry: is competition among suppliers ensured?
Over the last 15 years, many factors have affected the effective degree of competition in coal, electricity, gas and oil. This paper concentrates on the effects of globalisation, regulatory reform, privatisation and inter-fuel mergers. While demand side globalisation has led to increased competition, greater supply side globalisation might lead to more collusive behaviour in sectors such as coal ...

Prospects for nuclear power in Australia and New Zealand
The nuclear debate in Australia was recently enlivened by a Federal Government report (released in December 2006) on the economic viability of nuclear power as an option for electricity generation. Given the nation's large reserves of coal and gas, the question of the role of nuclear power rests to a large extent on future climate policy. Australia has the world's largest reserves of uranium and ...

The influence of climate change considerations on energy policy: the case of Russia
To those working on climate change, it is obvious that energy policy should be influenced by climate change considerations. The question that this paper seeks to answer is, to what extent do they influence policy and what contribution can a careful analysis of the costs and benefits of climate change options have on the formulation of that policy? We seek to understand this by looking in some ...

Forecasting of commercial energy consumption in India using Artificial Neural Network
The forecasting of energy consumption is essential for any country to study the future energy demand and to introduce the necessary government policies. This paper presents the formulation of forecasting models based on the Artificial Neural Network (ANN) for the consumption of conventional energy sources. In India, the total energy consumption for coal, oil, electricity and natural gas would be ...

West Virginia repeals the alternative and renewable energy portfolio standard
On February 3, 2015, West Virginia repealed the Alternative and Renewable Energy Portfolio Act that was originally passed and adopted in 2009. This Act (the Standard) required utilities serving 30,000 residential customers or more to generate at least 25 percent of their electricity from renewable sources by 2025. To be in compliance with the Standard, utilities could use coal (e.g., advanced ...

Influences of temperature and moisture on coal sorption characteristics of a bituminous coal from the Sydney Basin, Australia
Accurate testing of coal isotherms plays a significant role in the areas of coal seam gas drainage, outburst control, CO 2 geo-sequestration, coalbed methane (CBM) and enhanced coalbed methane recovery (ECBM). Coal isotherms were tested with CO 2 and CH 4 gases with a modified indirect gravimetric method in the University of Wollongong (UOW), Australia. The adsorption capacity of coal ...

Quantitative assessment of solar energy geo-policy risks
Fossil fuels, such as coal, oil, gas, and wood, are the major part of contemporary energy mix. However, forecasts predict that solar energy will take up to 70% of global energy mix by year 2100. Solar energy has embedded risks, e.g., social, geopolitical, health-related, etc. These risks should be addressed in advance to prevent negative consequences but little research has addressed systemic ...

Performance of externally fired combined cycle (EFCC)
The externally fired combined cycle (EFCC) which utilises coal as the primary fuel through a gas turbine cycle is a clean coal technology. Natural gas is used as the supplementary fuel, but the ultimate goal of the EFCC concept is a coal only option. In this study, the performance of the EFCC plant is evaluated based on the first and the second laws of thermodynamics, considering various levels ...
