MIT: Would You Drink Fracking Water If It Was Really Clean? Now You Can.

MIT: Would You Drink Fracking Water If It Was Really Clean?  Now You Can. | Gaz de schiste au Québec - Socialement et environnementalement responsable. | Scoop.it

New tech from MIT aims to clean the water used in fracking so much that you’d happily drink it, even though it was once filled with chemicals. 

 

One solution for dealing with the produced water: purify it really, really well.

 

A new water distillation process developed by researchers from MIT and King Fahd University of Petroleum and Minerals in Saudi Arabia vaporizes water under the boiling point when it comes into contact with a carrier gas. The resulting moist air bubbles pass through even cooler water and the vapor condenses. 

 

MIT’s technology works best in a smaller size--producing 1,200 to 2,400 liters of water a day, or the amount of water needed for a rural village. And unlike other desalination systems, saltiness doesn’t affect MIT’s technology, making it ideal for producing water from fracking.

Waste Management Launches Waterloo CNG Truck Fleet

For every vehicle that is converted to natural gas, use of diesel fuel is reduced by an average of 8,000 gallons per year. This reduces greenhouse gas emissions by over 22 metric tons per year, per truck.Vehicles powered by CNG emit nearly zero particulate emissions, cut smog-producing nitrogen oxide emissions by 50 percent compared to the cleanest diesel trucks, cut greenhouse gas emissions by over 20%, and are far quieter than diesel trucks.

New NOAA Peer-Reviewed Study: Atmospheric Methane Emissions From 50% Of US Biggest Shale Gas Production Regions Lower Than Expected - Journal of Geophysical Research: Atmosphere

New NOAA Peer-Reviewed Study: Atmospheric Methane Emissions From 50% Of US Biggest Shale Gas Production Regions Lower Than Expected - Journal of Geophysical Research: Atmosphere | Gaz de schiste au Québec - Socialement et environnementalement responsable. | Scoop.it

Good news—fracking's not as leaky as earlier studies suggested.

 

Full peer-reviewed new NOAA study presents measurements of methane  taken aboard a NOAA WP-3D research aircraft in 2013 over 50% of shale gas production in the US. 

 

Emissions LOWER than values extrapolated from the earlier studies.

 

- Haynesville region: 1.0–2.1%

- Fayetteville region: 1.0–2.8%

- Marcellus region (N-E Pennsylvania): 0.18–0.41%

 

Average estimated leakage is 1.1%, in close agreement with the EPA’s estimates.

The Remarkably Efficient Natural Gas Fuel Cell Car

The Remarkably Efficient Natural Gas Fuel Cell Car | Gaz de schiste au Québec - Socialement et environnementalement responsable. | Scoop.it
Three recent breakthroughs have made natural gas a very interesting fuel:

 

1) Ceramic fuel cells that can make electricity from natural gas at 60% efficiency.

2) ANG: Adsorption stores natural gas at low (500 psi) pressure in compact tanks.

3) A glut of cheap natural gas caused by new shale drilling/extraction techniques.

 

The fuel cell breakthrough is particularly important because it means a car can generate its own electricity more efficiently than a massive power plant!  Big plants typically average 30% efficiency, so a 60% NG fuel cell hybrid is twice as efficientas an electric vehicle charged from the grid. That means half as much fuel is consumed.

 

Twice as efficient as an electric car is saying a lot because electric cars are already three times more efficient than conventional cars.

 

This is because internal combustion engines are less than 30% efficient verses 90% for electric motors. Natural gas fuel cell cars are thus about six times more efficient than today’s cars. Using 1/6th as much fuel means pollution is also 1/6th . But NG is inherently very clean. and has 30% lower carbon content and virtually no sulfur, mercury, volatiles, and Nox so pollution is way less than 1/6th.

À l'IREQ - Pas si facile d’éliminer les carburants fossiles! Question de densité énergétique (99%)

« Dans un kilogramme d’essence, il y a 11 000 wattheures d’énergie, précise-t-il, alors qu’une batterie à lithium-ion d’un kilogramme contient environ 120 wattheures. La différence (99%) est donc énorme ! »

 

Il faut d’abord avoir à l’esprit qu’un litre d’essence, c’est une réserve d’énergie au même titre qu’une batterie. Toutefois, à poids égal, un litre d’essence contient 100xs plus d’énergie que nos meilleures piles. Et c’est là tout le défi que relève Karim Zaghib -chercheur en chef de l'IREQ depuis 20 ans.

Big Box Stores Could Ditch The Grid, Use Natural Gas Fuel Cells Instead, Help Electric Cars

Big Box Stores Could Ditch The Grid, Use Natural Gas Fuel Cells Instead, Help Electric Cars | Gaz de schiste au Québec - Socialement et environnementalement responsable. | Scoop.it

Large facilities like big box stores or hospitals could keep the lights on by using a fuel cell that runs off the natural gas that already flows in pipelines below most city streets.

 

Washington State University researchers have developed the first fuel cell that can directly convert fuels, such as jet fuel or gasoline, to electricity, providing a dramatically more energy-efficient way to create electric power for planes or cars.

 

A second paper on using their fuel cell with gasoline has been accepted for publication in the Journal of Power Sources.

 

Washington State University researchers have developed the first fuel cell that can directly convert fuels, such as jet fuel or gasoline, to electricity, providing a dramatically more energy-efficient way to create electric power for planes or cars.

 

The fuel cell system would produce 22% less carbon dioxide than large-scale natural gas combined cycle plants tied to the grid.

National Bureau of Economic Research: Fracking Boosted The Economy By 48G$/year During The Recession (2007-2013)

Fracking through the shale gas revolution created an economic boost during a time the economy needed all the help it could get, according to a new working paper published by the National Bureau of Economic Research.

 

Fracking boosted the economy by 48G$/year (37G$-56G$) between 2007-13,

The gains from fracking have not only gone to natural gas producers, but manufacturers and consumers as well.

 

Thanks to low natural gas prices, fracking created 24,000-65,000 extra jobs in gas-intensive industries. In industries that are less gas-intensive, fracking still created between 280,000-610,000 jobs.

 

The upper-bound estimate is significantly larger than all the jobs created in California in the last year, according to the Bureau of Labor Statistics.

USGS Study: Groundwater Quality Not Impacted by Bakken Fracking Activities

 

The paper is based on water samples collected by U.S. Geological Survey scientists from 30 randomly distributed, non-federal domestic wells screened in the upper Fort Union Formation. 

 

The study compared concentrations of several chemicals to health-based drinking-water standards, analyzed correlations between concentrations and oil and gas well locations and evaluated methane for indications of deep production-zone gases. 

 

“These results are good news for water users, and the data provide a valuable baseline against which future water-quality data can be compared,” said Peter McMahon, a USGS hydrologist and lead author of the study.

Satellite Dishes Can Turn Toxic Waste From Fracking Into Clean Water

Satellite Dishes Can Turn Toxic Waste From Fracking Into Clean Water | Gaz de schiste au Québec - Socialement et environnementalement responsable. | Scoop.it

Technology out of the Carnegie Mellon University.

 

Salty water is heated up and piped to a tiny membrane, a small white semi-circle of plastic cloth. On the other side of the membrane there’s cold water, so through simple condensation, clean water flows out of the system. The key though is getting the membrane just right.

 

This particular sample is a millipore membrane. It’s very similar to the polymer that is used to make Gore-Tex.  It allows water vapor to go through it, but no liquids.  Dirty water stays back, clean vapor travels through.
