How to create qualitative fuel from water and coal: case study
What is “coal-water fuel”? Coal-water fuel (CWSF or CWS or CWF) is a fuel which consists of fine dispersed coal particles, water and plasticizing agent. This type of fuel is widely used as an alternative to gas and black oil on different heat generating facilities. The operational economy is the main of advantages of the coal-water fuel. CW fuel has almost the same heat ...

Water Hungry Coal - Burning South Africa’s water to produce electricity
Safe, affordable and accessible water is regarded as one of our planet’s scarcest natural resources. This is particularly true on the African continent, where water insecurity is often an everyday reality. At the same time, equitable access to water is fundamental to life and human health and well-being. South Africa already struggles with water scarcity, and it is predicted that the ...

Influence and control of coal facies on physical properties of the coal reservoirs in Western Guizhou and Eastern Yunnan, China
Western Guizhou and Eastern Yunnan have abundant coal resources, and they are considered as the most prospective areas for coalbed methane (CBM) development in Southern China. To explore the potential of CBM production in these areas, this paper identifies the plane distribution of coal facies, and analyses its control on the physical properties of coal reservoirs. Four types of coal facies ...

The chronic toxicity of sodium bicarbonate, a major component of coal bed natural gas produced waters
Sodium bicarbonate (NaHCO3) is the principal salt in coal bed natural gas produced water from the Powder River Structural Basin, Wyoming, USA, and concentrations of up to 3000 mg NaHCO3/L have been documented at some locations. No adequate studies have been performed to assess the chronic effects of NaHCO3 exposure. The present study was initiated to investigate the chronic toxicity and define ...

Majority of China’s proposed coal-fired power plants located in water-stressed regions
To maintain its economic growth and provide for its massive population, China must reconcile two powerful, converging trends: energy demand and resource scarcity. One prime example of this tension is the country’s coal use and water supply. According to a new WRI analysis, more than half of China’s proposed coal-fired power plants are slated to be built in areas of high or extremely ...

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 ...

Use of reconstituted waters to evaluate effects of elevated major ions associated with mountaintop coal mining on freshwater invertebrates
In previous laboratory chronic 7‐d toxicity tests conducted with the cladoceran Ceriodaphnia dubia, surface waters collected from Appalachian sites impacted by coal mining have shown toxic effects associated with elevated total dissolved solids (TDS). The objective of the present study was to evaluate the effects of elevated major ions in chronic laboratory tests with C. dubia (7‐d exposure), ...

Water Risks on the Rise for Three Global Energy Production Hot Spots
Energy runs on water. In fact, among industries, the global energy sector is the world’s largest water user. Almost all forms of energy production and power generation depend upon water for their operations. This tension causes stress in both the energy and water worlds. Three-quarters of energy respondents to a 2012 CDP Global Water Survey confirmed that they experienced water-related ...

How do you transform a desert coal mine into an award-winning oasis? - Case Study
The Ukhaa Khudag coal mine lies in one of the harshest climate zones on the planet: the southern Gobi desert. In the winter, its pipelines and coal tailings dams would freeze. In the summer, much of its water would evaporate. Faced with these extreme conditions, the mine needed the most robust equipment available to conserve and reuse water from its tailings. Eight ANDRITZ SEPARATION belt ...

Computing with words on energy options? Towards decision-making under risk and uncertainty
Nature's real estate, such as water, minerals, oil and gas, and coal, is the precious gift available for the welfare of mankind since time immemorial. In spite of the efforts initiated by many countries in the development of non-conventional energy resources, it is too early to visualise that the gap between supply and demand of energy for the peaceful purpose could be bridged in the near future. ...

Are wind turbines economically viable in Britain?
If Britain establishes wind energy as their main energy source, they will be able to create a large number of new job opportunities. This can provide a huge influx of job opportunities in the short run since the implementation of wind turbines require a lot of manpower. Moreover, the maintenance of these wind farms can give life to a considerable amount of sustainable jobs. Monitoring the wind ...
