Fracking is considered one of the most controversial methods of obtaining the Earth's natural gases. It is also known as hydraulic fracturing, which involves drilling and introducing fluids (mainly water) into the ground to cause certain rocks to produce natural gases. Fracking could cause devastating effects on the environment. According to the article “Hydraulic Fracturing 101” on the website Earthworks.com, fracking can not only consume a lot of water, but it can also contaminate groundwater. Two to ten million liters of water can be used to fracture a single well. The water used for fracturing also contains many additives, such as hydrochloric acid, which can prove deadly for anyone who comes into contact with it. In “Hydraulic Fracturing 101” it is stated that in 2009, 8,000 gallons of fracturing fluid were spilled into a creek, resulting in a massive fish kill. Fracking can also cause air pollution due to the release of gases at the fracking site and also due to the hundreds of trucks needed to deliver water to the site. Now is it any wonder that fracking has so many critics. A Canadian company, known as GasFrac, has found a solution to this problem. Waterless fracking using gelled liquid petroleum which is said to evaporate underground and is much more environmentally friendly. This invention was featured in the "Top 25 Inventions of the Year 2013" section for the TIME Tech website. According to the Time Staff (2013), “Energy companies save money, and greens save breath.” This new style of fracking has far fewer critics than water fracking and will hopefully replace water fracking in the years to come. GasFrac uses a gel called LPG in its fracking, which is similar to propane. Some characteristics of this gel according to GasFrac are “low surface tension…half of paper…raises interest in waterless fracking. In the article “Waterless fracking makes progress in Texas…” by Kate Galbraith of the Texas Tribune, it is stated that as of March 27, 2013, there were approximately one hundred Texas wells using waterless fracking. But the article also goes on to say that waterless fracking is still in development and is still a rare site in the United States. However, the fact that many areas seem interested in the benefits of waterless fracking is a good start. Waterless fracking could potentially go down in history as one of the best “green” innovations. While it is still too early to determine the long-term effects on the environment, it appears to have solved many problems caused by conventional fracking with water. It is hoped that this development will lead to greater advancements in environmentally friendly technology.
