Natural Gas Leaks Across the US

Natural Gas Leaks Across the U.S.

What is a Natural Gas Leak?

A natural gas leak occurs when natural gas escapes from a natural gas storage facility. Methane, the main component of natural gas, spews out of these facilities into the atmosphere1. Methane is not only dangerous to the environment but also to living organisms2.

Natural gas is stored in facilities around the country to provide us with energy. Natural gas is quickly becoming an extremely prominent source of energy in the US. Natural Gas can also escpae into the atmosphere through natural sources9.

 

Why Are Natural Gas Leaks So Dangerous?

Methane can cause short-term health effects to humans, including, dizziness, headaches and vomiting3. Although no long-term effects have been observed, the short-term effects can be severe. Residents in areas of a gas leak often must be displaced1.

Methane has also been rumored to affect domestic animals, causing nosebleeds and shortness of breath. Residents in areas with gas leaks have observed animals falling ill and even dying4. However, little scientifically is known on what effect methane has on domestic animals.

The main concern of methane is the long-term effect this gas has on the environment. Methane, a greenhouse gas, is an extremely significant contributor to climate change5. Scientists estimate that methane warms the earth at 84 times the rate of carbon dioxide6.

 

Where in the U.S. Are These Leaks Happening?

The most recent Natural Gas leak has occurred in Porter Ranch, California7. The leak, caused by Southern California Gas Company, has been occurring since October 23rd 8. The California governor has declared a state of emergency, and 2,200 households have been displaced9.

The October 23rd leak is the largest natural gas leak in California’s history10. Stopping the leak has proved to be tricky, and could take up to four months6. The leak is coming from a mile and a half underground, making it a tough fix8.

However, California residents aren’t the only ones who will feel the effects. The leak’s impact on global warming is comparable to driving 4.5 million cars a day5. Environmental scientists communicate that this leak will affect everyone across the globe as temperatures rise.

Without a solution, 110,000 pounds of methane will continue to leak into the atmosphere hourly9. The leak negates California’s ambitious pledges to cut greenhouse gas emissions in coming years6. Estimates predict this leak has the same environmental effect as do six coal-fired plants daily5.

These leaks aren’t limited to California or even the United States. Leaks are prevalent all across the globe, some leaks more serious than others. A leak in Venezuela spewed 10 times the amount of methane as the California leak1.

To slow climate change, natural gas leaks around the world must be reduced.

Natural Gas: Fuel of the Future or Looming Disaster?

Natural gas and oil are underground fossil fuels. Both are obtained by drilling and release carbon dioxide and methane into the atmosphere. Natural gas is known for releasing significant amounts of methane when burned.

Carbon dioxide and methane are atmospheric greenhouse gases. Methane is the more potent gas in terms of trapping heat on the Earth. Therefore, there is controversy surrounding the use of natural gas as an energy source.

Gas drilling produces wastewater usually injected into underground wells. Earthquakes at sites in Oklahoma have been linked to this disposal practice. Authorities have called for the volumetric reduction of 27 wells in response to the quakes.

Another issue with natural gas is the possibility of leaks. A methane leak from a gas operation displaced residents of Porter Ranch, California this month. The governor of California declared a state of emergency.

The California leak is considered the worst environmental disaster since the Gulf BP spill. It is releasing the equivalent emissions of 4.5 million cars each day. Methane began spewing October 23, 2015 and is still leaking.

Natural gas is touted as a fuel that reduces carbon emissions. Its use has been advanced by President Obama’s political policies. The 2015 Clean Power Plan boosts renewables and natural gas as carbon-free substitutes for oil.

The promotion of natural gas is controversial among energy policy experts. Critics cite the potency of methane and the dangers of drilling against its use. Supporters claim a cleaner fuel option due to its lower carbon emissions.

Offshore drilling for natural gas is becoming a huge area of investment. Shell opened natural gas wells off the Irish coast recently. Israel has approved the development of offshore drilling operations.

These countries hope that offshore drilling for natural gas will bring them greater energy independence. They also consider natural gas a cleaner fuel alternative to oil. However, offshore drilling draws controversy as it damages marine environments.

Natural gas represents great wealth for countries that possess it. Qatar has created a big business producing liquefied natural gas (L.N.G.). The Arab country ships L.N.G. to lucrative Asian clients like China, India, and South Korea.

Qatar once relied on fishing and pearl diving to drive its meager economy. Now it is the wealthiest country by output per capita in the world. The United States and Australia are eager to follow suit by pursuing their L.N.G. resources.

Hydraulic fracturing or fracking is the process used to extract natural gas. Water, sand, and chemicals are injected into rock at high pressure to release the fuel. Fracking is a major issue surrounding the production of natural gas in the United States.

The US Geological Survey recently linked fracking to earthquakes in eight states, including Oklahoma. Oklahoma historically experiences two earthquakes a year above 3 on the Richter scale. The 1,427 Oklahoma quakes experienced in 2014 and 2015 are attributed to fracking activity.

Natural gas production is set to increase going into the future. Earthquakes and methane leaks will also likely increase. Time will tell whether natural gas is a clean fuel or an untenable environmental disaster.
