Decommissioning begins at two of largest U.S. coal-fired power plants
Navajo Generating Station, a 2.25-GW coal plant in Arizona, closed in November after 45 years of providing power. Owner Salt River Project (SRP) said it was uneconomical to continue operating. The focus has now shifted to decommissioning, long-term monitoring and ongoing operation of the transmission system. Working with SRP, a number of U.S.-based contractors will conduct demolition and ...

Fact Sheet: U.S. electricity markets increasingly favor alternatives to coal
The U.S. electric power system is gradually shifting toward cleaner forms of generation. One sign of this transition is the declining use of coal for electric power production. In 2011, use of coal for U.S. power generation dropped to its lowest level in more than a decade, according to the federal government’s independent U.S. Energy Information Administration (EIA). In fact, the EIA ...

A long year in the life of the US coal industry
With concerns about climate change mounting, the era of coal-fired electricity generation in the United States may be coming to a close. In early 2007, a US Department of Energy report listed 151 coal-fired power plants in the planning stages in the United States. But during 2007, 59 proposed plants were either refused licenses by state governments or quietly abandoned. In addition, close to 50 ...

Coal phase out case study: What Alberta can learn from Washington State
How Bruce Nilles and the Sierra Club cleaned up Washington state Renewable energy made up half of all the new power plantsconstructed in the world in 2014. That’s an incredible number made all the better when you think of what these plants are replacing. Big, bad coal. There are good reasons for this. Coal is not only the most carbon intensive form of energy available, but it has ...

Downsizing through technology management and outsourcing: a case study of a captive coal-mining organisation in India under globalisation
The organisation under discussion is a part of a Steel Company and consists of a group of captive underground coal mines required to produce coking coal, wash it in the coal washeries (benefitiation plants) and send the good quality clean coal to the steel plant for steel-making. The emergence of liberalisation in India has affected Indian industries and compelled them to think of ways to become ...

Understanding fuel switching under the EU ETS
Since the creation of the European Union Emission Trading Scheme (EU ETS), European power producers have monitored carbon emissions resulting from the composition of their production. Fuel switching is the main short–term abatement measure under the EU ETS. It consists in substituting combined cycle gas turbines (CCGTs) for hard–coal plants in off–peak power generation. Thereby coal plants run ...

Low-volatile coal combustion technologies in Vietnam: issues and strategies
Vietnam has planned to install a number of coal-fired power plants with unit's capacity of up to 600 MW. Present experience shows that available low volatile anthracite coal is difficult to burn in the PC fired boilers. In this paper, the CFB combustion technology is proposed based on the experiences of coal-fired power plants around the world used similar coal characteristics. Later, a ...

What is the future of King Coal in China?
When it comes to coal consumption, no other nation comes close to China. The country reigns as the world’s largest coal user, burning almost half of the global total each year. About 70 percent of China’s total energy consumption and nearly 80 percent of its electricity production come from coal, and its recent shift from being a historical net coal exporter to the world’s ...

Co-firing Solid Recovered Fuels (SRFs) with brown coal in large-scale pulverised fuel power plants – a simulation approach
The results of the numerical simulations performed in a pulverised fuel boiler co-firing coal and Solid Recovered Fuels (SRFs) are presented. SRFs are initially modelled as a mixture of two different fractions (biogenic and plastic) and further simplifications are proposed to save computational expenses. The SRF submodels are validated with available data obtained from a laboratory-scale ...

Coal-fired power on the way out?
The past two years have witnessed the emergence of a powerful movement opposing the construction of new coal-fired power plants in the United States. Initially led by environmental groups, both national and local, it has since been joined by prominent national political leaders and many state governors. The principal reason for opposing coal plants is that they are changing the earth’s climate. ...

Closing the door on building new coal-fired power plants in America
Community opposition, legal challenges, and financial uncertainty over future carbon costs are prompting companies to rethink their plans for coal. Since the beginning of 2007, 95 proposed coal-fired power plants have been cancelled or postponed in the United States--59 in 2007, 24 in 2008, and at least 12 in the first three months of 2009. This covers nearly half of the 200 or so U.S. coal-fired ...

How long will efficiency be the favored choice?
Energy efficiency creates an odd sort of market. Nothing (lack of energy use) competes for customers against something (energy generation). There is no free lunch and even nothing, energy efficiency, costs something. But for now it is cheaper than its main competitor, the power plant.In fact, it is often three times less costly to install efficient light bulbs, better insulate buildings or pursue ...

Light-bulb Liars II: Mercury and CFLs
The Washington Times ran a commentary July 11 that took a swipe at compact fluorescent lights. Titled “Light-bulb liars,” the article warns that broken CFLs are an “environment disaster in your family room” that “could poison the dog, the kid and the wall-to-wall rug.”To underscore the gravity of CFL dangers, the article then takes us through the Environmental Protection Agency’s step-by-step ...

Biomass Ready Coal Fired Plants and Massive Tree Planting will be the Compromise Climate Change Solution
Coal provided 26 percent of the additional power generation last year and 38 percent of all generation. There are 500,000 MW of new coal fired generation in the planning stage. This is more than was ever installed in the Americas and Europe. So any programs to reduce coal fired generation on these two continents to zero would eliminate less than is being added elsewhere in the world. The ...
