Hydraulic fracturing, more commonly known as fracking or fraccing, is used to stimulate and accelerate the flow of coal seam gas. The process involves high pressured injection of sand, water and chemicals into the coal seam gas well.
Is coal seam gas good or bad?
Coal seam gas is bad for the environment and we should all protest against its use. Genetically modified foods are a part of multinational plans to take over the world’s food supply. Wind farms are dangerous to human health and should be restricted.
Why is coal seam gas bad for the environment?
Possible environmental effects: environmental groups have raised concerns that CSG development might cause environmental damage through release of untreated production water at the surface; damage to, and contamination of underground aquifers by hydraulic fracturing; damage to wildlife habitat in sensitive areas and …
How is coal seam gas formed?
Coal seam gas (CSG) is primarily methane – a colourless and odourless gas, found in coal deposits formed over millions of years from fallen trees and other plant matter. Natural gas collects in underground coal seams by bonding to the surface of coal particles.
Is coal seam gas renewable?
Coal seam gas is a non-renewable energy resource that is a by-product of coal. It is a ‘pure’ and ‘non-toxic’ gas and for this reason has attracted a lot of commercial interest. During the process of coal formation, biogenic and thermogenic methane gas forms.7 мая 2012 г.
Why fracking is bad?
Hydraulic fracturing, or “fracking,” is revolutionizing oil and gas drilling across the country. However, without rigorous safety regulations, it can poison groundwater, pollute surface water, impair wild landscapes, and threaten wildlife.
Why is coal seam gas good?
Using CSG to generate electricity reduces CO2 emissions by up to 70 per cent compared with coal, and gas is critical to us meeting our greenhouse reduction targets. Gas is also the perfect partner to back up intermittent renewable energy sources such as wind or solar.
What does fracking mean?
Fracking is the process of drilling down into the earth before a high-pressure water mixture is directed at the rock to release the gas inside. Water, sand and chemicals are injected into the rock at high pressure which allows the gas to flow out to the head of the well.
For what coal is used?
Coal is primarily used as fuel to generate electric power in the United States. The coal is burned and the heat given off is used to convert water into steam, which drives a turbine.
Is CSG a fossil fuel?
It is the most abundant fossil fuel, both in Australia and globally. Australia has the world’s fourth-largest coal reserves.
How is gas mined?
The process involves high pressured injection of sand, water and chemicals into the coal seam gas well. The injection causes fractures in the coal seam allowing the gas to flow to the surface of the well. … Fracking has been used in coal seam gas operations in both Queensland and New South Wales.
How is coal extracted?
Coal can be extracted from the earth either by surface mining or underground mining. Once coal has been extracted, it can be used directly (for heating and industrial processes) or to fuel power plants for electricity. If coal is less than 61 meters (200 feet) underground, it can be extracted through surface mining.
How many CSG wells are in Australia?
40,000 coal seam gas wells
Is LNG better than coal?
The cleanest fossil fuel
The combustion of natural gas does not emit soot, dust or fumes. It generates 30% less carbon dioxide (CO2) than fuel oil and 45% less than coal, with a twofold reduction in nitrogen oxide (N0x) emissions and almost no environmentally-damaging sulphur dioxide (SO2) emissions.
Is coal seam gas the same as natural gas?
What is coal seam gas (CSG)? Coal seam gas, or coal bed methane (CBM, is a form of natural gas, typically extracted from coal seams at depths of 300-1000 metres.
Is natural renewable?
It’s considered renewable because of how easy it is to make, especially compared to nonrenewable energy sources like fossil fuels. … Although natural gases, no matter where we get them from, are cleaner than coal and other fossil fuels, they still produce some carbon emissions.
