Carbon Sequestration

In order to minimize the amount of human-produced greenhouse gases entering the atmosphere, numerous scientists have studied materials that could be used to capture excess carbon dioxide at one of its main sources – industrial smokestacks. Such substances have included metal-organic framework materials, ionic liquids, and even a sea urchin-inspired material. Unfortunately, however, not everything that's been suggested is inexpensive or easy to produce. That said, Norwegian researchers now believe that humble clay could do the job just fine.  Read More

The material could find use in smokestacks, or anyplace else where excess CO2 needs to be ...

We've already seen a number of technologies developed for capturing carbon dioxide emissions from smokestacks or other sources, but many of them have a limitation – in order to reclaim the captured CO2 for disposal, a considerable amount of energy is needed. Now, however, scientists at the University of California, Berkeley have developed a new carbon-capture material that requires far less energy in order to give up its payload.  Read More

Carbon sequestration may not, according to researchers at MIT, be the panacea that some had hoped. A recent study, partially funded by the United States Department of Energy, has found that far less carbon dioxide than the ideal prediction of 90 percent may be turned into rock when sequestered. This means much might eventually escape back into the atmosphere.  Read More

Hydrogen may hold promise as an alternative to fossil fuels, but there's still a huge petrol-producing infrastructure in place, and not many service stations offer hydrogen refills yet. That's why some scientists are exploring a bridging technology known as the integrated gasification combined cycle (IGCC) process, for converting fossil fuels into hydrogen. Along with hydrogen, though, carbon dioxide is also a byproduct of the IGCC process, which must be dealt with. Fortunately, scientists from the University of Liverpool have developed a polymer that soaks up that CO2 for use in other applications.  Read More

For years carbon capture and storage (CCS) has been considered a costly but necessary step in reducing emissions and protecting our environment. New research by Scandinavian research organization Sintef has found that refrigeration technology may reduce costs by up to 30 percent, increasing the potential for faster implementation.  Read More

Carbon capture is one of the many solutions proposed to curb emissions of CO2. But, so far, methods being used require a great deal of energy to release the captured carbon from the capture material for storage. Now researchers at the University of South Florida (USF), in a partnership with King Abdullah University of Science and Technology (KAUST), have announced what they claim is a more energy-efficient alternative in the shape of a cheaper, more efficient and reusable material for CO2 capture and separation.  Read More

Scientists have created a new material that adsorbs carbon dioxide emissions, then release...

Amidst concerns over the accumulation of atmospheric greenhouse gases, many research institutes have been looking into methods of carbon sequestration – the capture, storage and even possible reuse of carbon dioxide emissions. Unfortunately, some of the approaches require a considerable input of power, in order to release the captured CO2. A new material developed at Australia’s Monash University, however, requires nothing but sunlight.  Read More

The sea urchin has revealed a way to ceaply and quickly convert CO2 into calcium carbonate...

Carbon capture and sequestration in underground reservoirs isn’t the most practical or cost effective way to reduce atmospheric CO2 levels. It would be much simpler if CO2 could be quickly and cheaply converted into a harmless, solid mineral before it is released into the atmosphere. A team from the U.K.’s Newcastle University may have stumbled across a way to achieve this thanks to the humble sea urchin.  Read More

An international research team has been given the novel task of developing a practical means of monitoring underground stores of CO2 using none other than cosmic rays. The research hinges on the detection of the muons that occur as cosmic rays interact with the Earth's atmosphere, but which can penetrate several kilometers beneath the Earth's surface. It's thought that the approach could save significant amounts of money compared to alternative techniques.  Read More

Researchers at the University of Nottingham have developed another weapon in the ongoing war to reduce the amount of greenhouse gases emitted from fossil fuel-burning power plants. The researchers have created a new porous material called NOTT-300 that they claim is cheaper and more efficient than existing materials at capturing polluting gases, such as carbon dioxide and sulfur dioxide, from flue gas.  Read More
