Clean Coal Technology Essay

1 What is coal? Coal is a substance we consider today a fossil fuel, created from all the dead plants millions of years ago. Coal is formed from prehistoric plants that when they die are not able to release the energy they built up from photosynthesis Typically the plants had fallen into large swamps and bogs, and then over time the dead plants lying on the bottom of the swamps and bogs were slowly covered with other dead plants and sediment build-up. Once buried the plants were subjected to high amounts of pressure and temperatures, which over long periods of time it becomes peat then eventually creates coal. We refer to coal as a “fossil fuel” today because it is created from prehistoric plants and the coal we have today has been millions of years since it was in plant form. Today we coal is still being created we just don’t fully recognize it because how long the process actually takes.

Coal is the dirtiest of all fossil fuels. When burned, it produces emissions that contribute to global warming, create acid rain and pollute water. With all of the talk surrounding nuclear energy, hydropower and biofuels, you might be forgiven for thinking that grimy coal is finally on its way out. On the other hand, coal is no sooty remnant of the Industrial Revolution - it generates half of the electricity in the United States and will likely continue to do so as long as it's cheap and plentiful . Clean coal technology seeks to reduce harsh environmental effects by using multiple technologies to clean. Coal is a fossil fuel composed primarily of carbons and hydrocarbons. Its ingredients help make plastics, tar and fertilizers. A coal derivative, a solidified carbon called coke, melts iron ore and reduces it to create steel. But most coal - 92 percent of the U.S. supply - goes into power production .Electric companies and businesses with power plants burn coal to make the steam that turns turbines and generates electricity. When coal burns, it releases carbon dioxide and other emissions in flue gas, the billowing clouds you see pouring out of smoke stacks. Some clean coal technologies purify the coal before it burns. One type of coal preparation, coal washing, removes unwanted minerals by mixing crushed coal with a liquid and allowing the impurities to separate and settle. Other systems control the coal burn to minimize emissions of sulfur dioxide, nitrogen oxides and

Clean coal technology usually addresses atmospheric problems resulting from burning coal. Historically, the primary focus was on sulfur dioxide and particulates, since it is the most important gas in the causation of acid rain. More recent focus has been on carbon dioxide (due to its impact on global warming) as well as other pollutants. Concerns exist regarding the economic viability of these technologies and the timeframe of delivery, potentially high hidden economic costs in terms of social and environmental damage, and the costs and viability of disposing of removed carbon and other toxic matter. More, the byproducts of coal power production range from fly ash sludge ponds full of mercury, arsenic, and sulfur in unlined ponds that can leak into the water supply.

Coal ash is a byproduct of burning coal in power plants and is composed mainly of aluminum and silicon oxides. This ash is commonly stored away in dump sites, only to leach out solutions of concentrated toxic heavy metals. Such issues are detrimental to the health of water systems, posing both a human and environmental health risk. However, there are solutions to this problem. Coal ash possesses unique chemical properties that allow for the remediation of other environmental concerns, such as the treatment of soil polluted with heavy metals, the removal of nutrients from wastewater, and the remediation of acid mine drainage in streams.

Oscar starts off by stating "Coal, the source of half the energy in the United States, has been dirtiest of all fossil fuels because it creates harmful emissions when burned." He goes on to talk about the new technologies that are being developed of clean ways to use coal. These technological advances "purify exhaust gasses as coal burns" which are called wet scrubbers. Low NOx burners prevent harmful emissions from happening in the first place. There is even a process called gasification, which avoids burning coal to

Jason Hayes, communications director for the American Coal Council says “the industry over the past few decades had invested over $100 billion in cleaning up emissions and it’s already been effective. All of the important noxious pollutants have decreased markedly over the last 30 to 40 years. We’ve been doing all of this on top of dealing with everything else.” Coal may not be green, but it is a source of energy American needs. It is cheap and efficient. Without coal, America wouldn’t be anywhere near where it is today. The coal mined here isn’t just used for energy. America’s

The narrative of clean coal has been propped up by the industries primary lobbyist group, the National Mining Association, with a budget of nearly twenty million dollars a year (Coniff). Lobbying is a natural part of the political process, but the issue becomes when the lobbying is disingenuous and the coal industry has zero intentions of implementing clean coal, based on the fact that no coal plants currently in the United States make use of any of the technology. Although the technology is still being developed, there are no future plans to implement it as well. On the other side, those who speak out against coal and clean coal are naturally groups concerned about the environment, such as the Environmental Protection Agency and green advocacy groups. They recognize that coal power plants are the primary contributor to greenhouse gas emissions in the United States and thus their emissions must be controlled (Eilperin and Mufson). They also believe even though limiting coal power plants will cost a great deal of money, the American people will have a net benefit due to lower public health costs as a result of air pollution while also benefitting globally by reducing greenhouse gas fueled climate change. Essentially, clean coal is pursued by those who have a vested commercial interest in its being as a mainstay of electricity generation, while those who oppose it are against the negative health and climate effects it

Coal’s reputation has become as black as coal itself, but without it the quality of life that hundreds of millions of people enjoy today would not be possible. Coal has been used in many ways throughout history and it will continue to be a vital resource in supplying the energy needed to fuel an energy hungry world. Research cited throughout this paper suggests that coal is an energy source for the future because it is stable and reliable with abundant reserves, it is the most affordable and efficient fuel source used to produce power, and because of new clean coal technologies, coal can be burned with minimal to no damage to the environment.

Coal cleanup is very hard work and not a lot of people would want to do it. Their clean up plains are very weak right now and they should have someone to improve and successfully make it better every year. A lot of coal companies have filled bankrupt and have been in the courts because they will have to close down and have very expensive cleanup bills.

What is Pollution? Pollution is the introduction of contaminants into the natural environment that cause adverse change. Pollution can be in forms of chemical substances, such as heat noise or light. What are pollutants? A pollutant is a substance that pollutes something, especially water or the atmosphere. How is coal related to pollution? Coal is related to pollution in two ways . . . the first one is by CO2 emissions that absorb ultraviolet rays from the sun which causes temperatures to rise, the second one is causing pollution because when it’s being mined it’s destroying public land and mountains. The CO2 emissions are caused by the chemicals in the coal. Coal is made up of mostly Carbon but also has many traces of Sulfur, Nitrogen, Hydrogen,

Coal is the most abundant and important source of primary energy in the world. There are reserves spread throughout some one hundred countries to meet global needs up to the next two hundred and fifty years. It is the most important fossil fuel for electricity generation and industrial purposes. But, it has pollution issues to the environment like Air pollution, land degradation, noise pollution, etc. But the pollution I am going to be talking about is water pollution from the coal mines in the Alabama rivers.

Growing up in South Jersey, I grew up near the coal burning electric plant so I wanted to check out what the impact of burning of coal would have on the environment and on people’s health that could be living near the plant.

Coal is a hard, black colored rock-like substance. It is made up of carbon, hydrogen, nitrogen, and varying amount of sulphur. Coal was form as decomposition took place in the absence of oxygen and much of the hydrogen content of the matter was eroded away, leaving a material rich in carbon. The material was compressed over the years by sand and dirt, leaving the form of a carbon known as coal. The different types of coals are Anthracite, bituminous, lignite, peat, coke, and charcoal. Coal is mined out of the ground and used to produce energy. However, they are many deaths, injuries, and sickness involved in mining coal.

Coal, a mineral I have discussed previously, is necessary to our everyday lives. Coal is an incredible source of energy; it heats our houses and buildings, and also fuels stoves. You may often wonder where this extremely useful mineral comes from. Coal does not just appear; it needs to be mined through a process which results in our being able to utilize it. Coal mining is fairly inexpensive, is carried out on a large scale and can be mined in either underground or surface mines.

CO2 is the most significant greenhouse gas, which mainly comes from the use of fossil fuels. Many people feel that content of CO2 in the atmosphere is the main reason for manmade global warming. The main sources of CO2 emissions involve electricity generation, industrial processes, fumes from transportation and commercial buildings and use. Emissions of greenhouse gases, such as CO2, to the atmosphere are expected to cause even more of a significant change in global climate (Davison, 2007). The main focus to try to reduce the amount of carbon dioxide in the atmosphere is to reduce the amount that is released from coal-fired power plants. Greenhouse gas emissions that involve the productions of electricity come from natural gas production and coal-fired power plant operations. Natural gas production accounts for twenty-four percent and coal-fired power plant operations accounts for seventy-five percent, while the other one percent is caused by other electricity generation operations. The main reason why coal-fired power plants have a higher percentage of emissions is because the sulfur content of coal is much higher than that of other fossil fuels (Jarmaillo et al., 2007). This proves that there is a great need to find an alternative fossil fuel to use instead of coal. Although coal is easy to mine, transport and process for the electricity generation process, it is also the
