CSG is natural gas (methane) which is sourced from underground coal formations, sometimes known as coal bed methane (See Figure 1). CSG is increasingly being used to supply gas to eastern Australia. In conventional gas fields, the gas exists in permeable sandstone reservoirs.
Is coal seam gas the same as fracking?
Coal seam gas (CSG) and the gas that comes from shales are chemically very similar. They generate the same amount of heat and CO₂ when burned in your heater or at an electricity power plant. … Shale reservoirs always require fracking, while perhaps only half of coal seam gas reservoirs require fracture stimulation.
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.
How does coal seam gas work?
Coal seam gas is held in place by water pressure. To extract it, wells are drilled through the coal seams and the water pressure is reduced by extracting some of the water. This releases natural gas from the coal. … In some cases hydraulic fracturing, or ‘fracking’, is used to extract coal seam gas.
Where is coal seam gas found in Australia?
Australia’s major coal seam gas resources are found onshore in eastern Australia. Currently the largest known proven reserves are in Queensland’s Bowen and Surat basins. CSG has been produced from these areas since the mid 1990s. Until recently, the bulk of supply has been derived from the Bowen Basin.
Why is coal seam gas so controversial?
Coal seam gas (CSG) is a polarising issue in some communities. Proponents argue that CSG is a vital energy resource, necessary for continued gas supply. Opponents claim that CSG could have serious environmental and social impacts.
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.
Why is gas bad for the environment?
Gasoline use contributes to air pollution
The vapors given off when gasoline evaporates and the substances produced when gasoline is burned (carbon monoxide, nitrogen oxides, particulate matter, and unburned hydrocarbons) contribute to air pollution. Burning gasoline also produces carbon dioxide, a greenhouse gas.
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.
What is a seam of coal?
: a bed of coal usually thick enough to be profitably mined.
How is coal formed?
Coal is formed when dead plant matter decays into peat and is converted into coal by the heat and pressure of deep burial over millions of years.
How does coal affect the environment in Australia?
Coal is a major source of rising greenhouse gas causing climate change. The burning of coal emits hazardous air pollutants, including particulate matter, sulphur dioxide, nitrogen oxides, carbon dioxide, mercury and arsenic. Australia has one of the most carbon intensive and polluting electricity supplies in the world.
How many CSG wells are in Australia?
40,000 coal seam gas wells
How many fracking wells are there in Australia?
In north-east SA, fracking has been undertaken in the Cooper Basin since the late 1960s in over 700 wells. Some of Australia’s biggest gas players have gas projects in this basin, including Santos, Beach Energy (ASX: BPT), Cooper Energy (ASX: COE) and Senex Energy (ASX: SXY).
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.
