Sequestration of CO2 has been discussed as one way to reduce the impact of burning fossil fuels on climate change by removing CO2 from industrial and power generation emissions and storing it indefinitely underground. This technology has been demonstrated in the laboratory and in pilot studies, but not in large scale tests. That is now changing.

Aging, Diseased Trees a Large Source of Methane Emissions, Study Says
written by Yale Environment 360
Aging and diseased trees emit significant amounts of methane into the atmosphere, a phenomenon that may be contributing to global climate change, a new study says.
In samples collected from a forest in northeastern Connecticut, researchers at the Yale School of Forestry & Environmental Studies found that some
Columbia University scientists say that technologies to extract carbon dioxide from the air will likely become a critical part of any strategy to stabilize the global climate and should not be abandoned because of high costs.

Carbon in Fractions: CoolPlanet Makes Renewable Biofuels and Sequesters Carbon
written by Walter Wang
CoolPlanet Energy Systems (CoolPlanet) is a Camarillo, California, company that is developing a “negative carbon” drop-in gasoline replacement fuel from biomass.
According to the company’s web site, the fuel is made using proprietary biomass fractionator
Adding a charred biomass material called biochar to glacial soils can help reduce emissions of the greenhouse gases carbon dioxide and nitrous oxide, according to U.S. Department of Agriculture (USDA) scientists. Studies by scientists with USDA’s Agricultural Research Service (ARS) are providing
Carbon sequestration is the capture of carbon dioxide (CO2). This is the process of carbon capture and storage, where carbon dioxide is removed from flue gases, such as on power stations, before being stored in underground reservoirs. There are also natural sequestration processes such as the ocean.
If natural gas is a “bridge fuel,” what’s on the other side?
This question kept popping up in recent weeks as a series of reports predicted gas would become a growing part of the global energy mix in the coming decades. Gas, while cleaner burning than coal, still falls short of the low-emissions scenarios envisioned by world leaders,
Biochar is charcoal type created by the pyrolysis of biomass, and differs from ordinary charcoal only in the sense that its primary use is not for fuel, but for biosequestration or atmospheric carbon capture and storage. As much as 12 percent of the world’s human caused greenhouse gas emissions could be sustainably offset by producing biochar.
Global Warming is caused by several factors such as the release of greenhouse gases like carbon dioxide into the atmosphere. One solution to the problem is to capture the carbon dioxide before it enters the atmosphere, and instead, deposit the CO2 into the ground. However, up to this point, scientists have been unable to effectively track how it might move underground. The desire is to get the CO2 in place and not have it move elsewhere and potentially cause problems. Now, with the advent of Electrical Resistivity Tomography (ERT), developed at the
While coal-fueled power plants are directly responsible for roughly one-third of our CO2 emissions, the DOE indicates that coal is expected to dominate our domestic power generation at least for the next 25 years. Globally, the increased demand for coal-fueled electricity will translate into a 57% rise in related CO2 emissions by 2030 according to the IEA.
One technology that attempts to solve the CO2 emissions crisis is carbon capture and storage, or CCS. Generally speaking, CCS captures the CO2 emissions from coal power plants and other industrial sites and injects the CO2 into underground porous rock formations in hopes of permanent sequestration.
A colleague of mine said to me recently, “No energy is clean energy.”
Which got me thinking. Of course, Clean Coal comes to mind. And people love to say that “No coal is clean,” and “Clean Coal is an oxymoron.”
OK, OK. It’s not the best marketing term I’ve ever heard. There is a U.S. Department of Energy program that uses the term, and that program has funded gasification and carbon sequestration projects. So there is such a thing, whatever you want to call it. How about “Clean(er) Coal”?
Then I thought about wind. Big, majestic, white turbines … cutting up birds that fly into them. Whoops. That’s not very clean.
