Should we stop the ongoing Coal Bed Methane (CBM) projects at the Tanjore Delta of Tamilnadu? Are the allegations such as the “project may the spoil environment and take away the livelihood of farmers around”, is this true? How far it is justifiable ?
SO WHAT ARE THE IMPACTS:
Ground Water depletion
Continuously removaing water from coal beds depletes ground water and may eventually lower farmer’s boreholes and underground waterlevel. It can also change the flow of good fresh groundwater to into the coal seams.
Waste Water Disposal
Millions of litres of produced water have to be disposed of from each well. Over time this represents a massive volume of water and toxic material released into rivers, estuaries and the sea.
Leaking Wells & Drinking water contamination
The steel and concrete pipes plunged deep into the ground will decay slowly over time. All gas wells will leak eventually. The possibility of the water used in fracking to contaminate water in rivers and other bodies of water is pretty high.
Air & Noise Pollution & Infrastructure damage
Road damage is an inevitable consequence of methane exploration due to intensive transportation of materials and machinery.
Global Warming & Earth Quakes
CBM is not green, it is not the replacement for traditional fossil fuels, it’s just another energy extraction technique, thus we ‘re only keep expanding the hydrocarbon and emissions. We’re already witnessing the bad effects interms of global warming and frequent earth quakes.
WHAT IS MY VIEW:
I do support technology and development; but this one is not required for our country - where there's already a huge water scarcity; poor infrastructure, corrupted environment/safety regulatory bodies, and greedy business men backed by fraud politicians. Why should we risk the livelihood of our future generations for the profits of certain corporates ?
In the end, I just can’t imagine the beautiful green surrounding of Cauvery delta region turning into a dark coal dump; pure breeze of air to go polluted with chemicals and dangerous gases; chirping sounds of sparrows to change into blasting bore well bombs and restless truck noises; and finally the poor people of these region will loose all they have got and become the refugee of their own land😢 #SaveNeduvasal #banhydrocarbonproject #savefarmer #saveagriculture
I read a bit about the whole process. Let me share what I learnt, then you can answer the above questions yourselves!.
HOW DOES CBM WORK :
Naturally formed Methane in the underground coal marcels will get released when they are de-pressurized. CBM companies drill deep wells into these coal beds and pumping out all the surrounding water, so that the coal seal gets de-pressurized and lets out the methane to flow as a gas up through the pipes. Methane is then compressed and commercialized into market. It is often also necessary to stimulate the coal seam via fracking (process of fracturing the solid ground layers with high pressure chemicals/liquids) in order to maximum extract of gas.
