There are several ways to remove CO2 from a stack gas. None have reached a commercial basis yet due to the expense of the processing. The current method of removing the greenhouse gas carbon dioxide (CO2) from the flues of coal-fired power plants uses so much energy that no one bothers to use it. So says Roger Aines, principal investigator for a team that (more…)
A new study conducted by the University of Buffalo has found that state regulation helped reduce environmental problems associated with unconventional forms of natural gas drilling in Pennsylvania since 2008.
In an analysis of 2,988 violations at nearly 4,000 Pennsylvania hydraulic fracturing drill sites, university (more…)
Secretary of the Interior Ken Salazar approved this week a major natural gas project in Utah’s Uinta Basin that could develop more than 3,600 new wells over the next decade. The project will support up to 4,300 jobs during development.
By signing the Record of Decision (ROD) for the Greater Natural Buttes Project, proposed by Anadarko Petroleum Corporation, Secretary Salazar approved up to 3,675 new gas wells in an existing gas producing area in Uintah County, Utah. The decision follows a landmark comprehensive public consultation and conservation stakeholder involvement effort that resulted in a balanced approach to energy production and environmental protection that will boost America’s energy economy.
The project encompasses approximately 163,000 acres — but will bring new surface disturbance to just five percent of that area (approximately 8,100 acres) as a result of the 1,484 well pads approved in the ROD, which would be drilled over a period of 10 years.
The ROD was signed at a ceremony at the Kern River Compressor Station in Salt Lake City. Secretary Salazar and Director Abbey were joined by BLM Utah Director Juan Palma and representatives of Anadarko, the Wilderness Society and the Southern Utah Wilderness Alliance.
The BLM prepared the Final Environmental Impact Statement (FEIS) or the project in coordination with the Bureau of Indian Affairs and Uintah County, which participated as formal cooperating agencies during the EIS process. The BLM also closely coordinated with the U.S. Fish and Wildlife Service and the Environmental Protection Agency to ensure their concerns were addressed.
As a result of a collaborative process among federal, state, local and tribal governments, Anadarko and the Utah conservation community, the project will implement best management practices in the project area to safeguard air quality and protect crucial big game winter range, sage-grouse and sage-grouse habitat, sensitive soils, visual effects and recreational use.

A new study estimates that fluids used in the hydraulic fracturing of natural gas in the Marcellus Shale region can migrate into underground drinking water supplies far more quickly than experts have previously estimated.
The study, based on computer modeling and funded (more…)
Germany has installed enough photovoltaics such that coal-fired power plants are beginning to become unprofitable. This is driven by a combination factors, e.g., that coal isn’t asked to provide power at the peak of the day, when both the sun and the price of electricity are at their zenith. Of course, most of us cheer when coal runs into trouble, but issues like this (more…)
Two years ago, an explosion on BP’s Deepwater Horizon drilling platform killed 11 workers and marked the beginning of a prolonged environmental disaster now acknowledged as the worst in American history. Before the Macondo well was finally capped, more than two hundred million gallons of crude oil had gushed into the Gulf of Mexico, killing untold (more…)
A planned shale gas drilling project in New York state would utilize a waterless form of hydraulic fracturing, a new technique designed to reduce the potential pollution associated with the controversial natural gas drilling process.
Rather than using typical hydraulic fracturing (more…)
Shale oil, known also as kerogen oil or oil-shale oil, is an unconventional oil produced from oil shale by pyrolysis, hydrogenation, or thermal dissolution. These processes convert the organic matter within the rock (kerogen) into synthetic oil and gas. The resulting oil can be used immediately as a fuel or upgraded to meet refinery feedstock (more…)
A new study says that methane leaks from natural gas drilling, particularly hydraulic fracturing, are likely higher than previously estimated and concludes that converting vehicles from gasoline to compressed natural gas will actually produce more greenhouse gas emissions unless methane leaks are significantly reduced.
