AUSTIN, Texas — A new study correlates a series of small earthquakes near Snyder, Texas between 2006 and 2011 with the underground injection of large volumes of gas, primarily carbon dioxide (CO2) — a finding that is relevant to the process of capturing and storing CO2 underground.
Although the study suggests that underground injection of gas triggered the Snyder earthquakes, it also points out that similar rates of injections have not triggered comparable quakes in other fields, bolstering the idea that underground gas injection does not cause significant seismic events in many geologic settings.

AUSTIN, Texas — A report from the Massachusetts Institute of Technology (MIT) and The University of Texas at Austin urges the U.S. to accelerate efforts to pursue carbon capture and storage (CCS) in combination with enhanced oil recovery (EOR), a practice that could increase domestic oil production while significantly curbing emissions of carbon dioxide (CO2).
For decades the oil industry has used CO2 to extract oil from mature fields, often relying on purchased CO2 from natural sources. The idea of seeking CO2 from industrial sources, such as coal- and natural gas-fired electricity plants, has gained currency because of public concerns about carbon dioxide emissions.(more…)
*Berkeley Lab joint report offers a variety of scenarios to reduce emissions to 80% below 1990 levels.*
Berkeley, CA — In the next 40 years, California’s population is expected to surge from 37 million to 55 million and the demand for energy is expected to double. Given those daunting numbers, can California really reduce its greenhouse gas emissions to 80 percent below 1990 levels by 2050, as required by an executive order? Scientists from Lawrence Berkeley National Laboratory who co-wrote a new report on California’s energy future are optimistic that the target can be achieved, though not without bold policy and behavioral changes as well as some scientific innovation.
The report, titled “California’s Energy Future—The View to 2050,” draws a series of energy system “portraits” showing how California can meet its ambitious emissions targets using a combination of measures and energy sources that may include electrification, enhanced efficiency, nuclear energy, renewable energy sources, grid modernization, and carbon capture and sequestration (CCS).

Fossil fuels (mainly coal powered power stations) emits about one-third of all carbon dioxide (CO2) that goes to the atmosphere every day. As it’s a well-known greenhouse gas, therefore many attempts are being made to capture it from the power stations and to store it underground in the geological formations. The aim is therefore towards ‘zero emission’.
