Volcanic rocks deep under the population centers of New England, New Jersey, and New York might be ideal for storing carbon dioxide generated by next-generation coal-fired power plants. The type of rock, basalt, is important to the plan because it reacts with the CO2, turning into a solid mineral.

A new type of natural-gas electric power plant proposed by MIT researchers could provide electricity with zero carbon dioxide emissions to the atmosphere, at costs comparable to or less than conventional natural-gas plants, and even to coal-burning plants. But that can only come about if and when a price is set on the emission of carbon dioxide and other greenhouse gases.

A team of researchers at the Massachusetts Institute of Technology has developed a new modeling methodology for determining the capacity and assessing the risks of leakage of potential underground carbon-dioxide reservoirs.

In a provocative new study, a Univ. of Utah scientist argues that rising carbon dioxide emissions—the major cause of global warming—cannot be stabilized unless the world's economy collapses or society builds the equivalent of one new nuclear power plant each day.

Any calculation of the carbon footprint of a gallon of milk needs to include fuel used by tractors and trucks, as well as electricity consumed by milking machines and refrigerators. But how much gas is coming from the cows themselves? That's the question Purdue Univ. researchers are investigating as they start a new study aimed at measuring greenhouse gases from dairy cows.

A team from Louisiana Tech Univ. and Trenchless Technology Center is conducting innovative research on geopolymer concrete and providing ways to use a waste byproduct from coal fired power plants and help curb carbon dioxide emissions. Inorganic polymer concrete (geopolymer) is an emerging class of cementitious materials that utilize "fly ash", one of the most abundant industrial by-products on earth, as a substitute for Portland cement, the most widely produced man-made material on earth.

Researchers at MIT have shown the benefits of a new approach toward eliminating carbon-dioxide (CO2) emissions at coal-burning power plants. Their system, called pressurized oxy-fuel combustion, provides a way of separating all of the carbon-dioxide emissions produced by the burning of coal, in the form of a concentrated, pressurized liquid stream. This allows for carbon dioxide sequestration: the liquid CO2 stream can be injected into geological formations deep enough to prevent their escape into the atmosphere.

Efficient methods for the separation of this greenhouse gas from industrial exhaust are being sought. Korean researchers have now developed a porous material that can bind and store CO2 efficiently and highly selectively. The lattice-like network contains flexible "columns" that can open the pores of the three-dimensional lattice for CO2.

The Department of Energy's Pacific Northwest National Laboratory has developed a reusable organic liquid that can pull harmful gases such as carbon dioxide or sulfur dioxide out of industrial emissions from power plants. The process could directly replace current methods and allow power plants to capture double the amount of harmful gases in a way that uses no water, less energy and saves money.

A 1930s house built in 2008 is about to undergo the first of three energy efficiency upgrades which will ultimately convert an energy inefficient house into a zero carbon home designed to meet the Government’s 2016 CO² targets for all new housing.
