So what is Fracking, how does it work and why does it have such an awesome name?
Fracking is short hand for hydraulic fracturing and refers to how the rock is fractured apart by a high pressure mixture of water sand and chemicals. Experts also like to refer to a ‘frac job' (oo er!) and a ‘frac unit’.
It is a process in which giant drills are used to dig deep into the earth whilst creating tiny explosions to shatter shale rocks, releasing the gas inside. The ‘mixture’ is injected into the rock at very high pressure which causes the gas to flow out to the head of a man made well.
Fracking does have a few enemies and as with most things to do with any ‘non green’ energy is thought of as controversial. Much of the water used in the process is collected and then filtered and cleaned. There are concerns that potentially carcinogenic chemicals can sometimes escape and end up in drinking water. However the industry itself vigorously denies these claims. The other hot topic you will see people protesting about is climate change and global warming, although shale gas emissions from natural gas are much lower than those from coal and oil.
