Do CO2 Injections Pose Risk of Harmful Earthquakes?
How common are measurable earthquakes in association with oilfield operations? The answer is: exceedingly rare. Nevertheless, another scientific paper has raised the possibility of seismic events occurring as a result of injection of CO2 to stimulate new oil production from depleted oil fields. Since this process, known as enhanced oil…

Peak Coal in China — or Long, High Plateau?
China coal power is one of the world’s largest single contributors to carbon dioxide emissions, which will likely need to be reduced to near-zero levels over the next few decades to manage climate change. So when two reports came out in the last few weeks that project a peak in…

Carbon Capture and Storage – Why It’s Essential
EPA’s move last week to regulate greenhouse gas emissions from new power plants marks the beginning of an era of widespread use of carbon capture and storage (CCS) in fossil power generation. Going forward, in the absence of any other technology allowing emissions reductions, all new coal-fired power plants must…

Seismicity and carbon storage: MIT responds to Zoback
In the December 2012 issue of the Proceedings of the National Academy of Sciences (PNAS), a published letter by MIT researchers Ruben Juanez, Howard Herzog and Brad Hagar provides several cogent geophysical counter-arguments to a 2012 PNAS Perspectives piece by Stanford researchers Mark Zoback and Steve Gorelick. The two had…

The Dash for Gas – No Climate Cure Without CCS
With the advent of unconventional gas technologies, the energy industry has turned toward natural gas as an alternative to coal, a step to energy independence and a solution to climate change worldwide. However, without CCS, natural gas will be unable to achieve needed reductions from the utility sector without carbon…

Seismic Risk Won’t Threaten the Viability of Geologic Carbon Storage
This week’s rumblings against carbon capture and storage (CCS) as a powerful means to mitigate global climate change come not from any natural geological source, but solely from an opinion piece published in this week’s Proceedings of the National Academy of Science (PNAS) Perspectives. Despite the arguments of two Stanford…

Fracking and Geologic Carbon Storage Can Safely Coexist
A recent paper by Princeton researchers published in Environmental Science and Technology questions the compatibility of hydraulic fracturing (“fracking”) and geologic carbon storage and has received an unwarranted amount of attention. Despite the conclusions of the paper, the overwhelming evidence suggests that geologic storage can indeed coexist safely with other…

At Last: A First Step on GHGs
Last week, the Administration took a bold step forward to curb greenhouse gas emissions. In a long-anticipated action, EPA proposed new source performance standards (NSPS) for fossil-fueled power plants that would limit emissions from new plants to a rate of 1,000 lbs. of CO2 per megawatt-hour, averaged annually. This level…
