Carbon Sequestration

A diagram detailing the new device from MIT. Air or flue gas can be pumped into the device (bottom), which captures carbon dioxide (red) from it, leaving only fresh air (blue) to come out. When the device is full, it can be flushed out and captured as pure CO2 for industrial use

"Electro-swing" battery captures CO2 from power plants or ambient air

Researchers at MIT have developed a new method for pulling carbon dioxide out of a chimney flue at a power plant or even just ambient air. The new device is a specialized battery that absorbs CO2 while charging, then releases it for industrial use.

Researchers have developed a new way to turn captured carbon dioxide gas into solid "coal"

Scientists use liquid metals to turn carbon dioxide gas back into coal

Capturing carbon from the air and sequestering it is emerging as a viable strategy, and now scientists have developed a new method to turn CO2 gas back into solid coal, that can then be buried, or even used for electronic components.

Holier-than-thou: Highly porous powder captures double the carbon

A promising new technology developed at Canada’s University of Waterloo hinges on a special kind of powder that could be applied as a filter at power plants to gather CO2 molecules at the source, and is claimed to offer double the efficiency of the materials that are currently available.

Climeworks: The ambitious startup out to reverse climate change by capturing carbon from the air

Climeworks is a Swiss company at the vanguard of carbon capture technology, and having just completed a year-long pilot project collecting C02 at the world’s first negative emissions power plant, is rather optimistic about the way things are headed.

The fuel was used in a 747 flying from Florida to London

"Recycled-carbon" jet fuel gets its first commercial use

It was back in 2011 that we first heard how Virgin Atlantic Airways was planning to use an eco-friendly aviation fuel made from captured steel mill waste gases. A successful test flight followed in 2016, and the fuel has now been utilized in a commercial flight for the first time.

World's first "negative emission" power plant turns CO2 into stone

After opening the world’s first commercial Direct Air Capture (DAC) plant designed to pull CO2 out of the air, Swiss company Climeworks is now joining forces with a geothermal power plant in Iceland to create the world’s first “negative emission” power plant.

Climeworks has opened its first Direct Air Capture (DAC) plant, which captures CO2 from a waste recovery facility in Zurich, Switzerland

Rooftop CO2 capture system pipes greenhouse emissions to a greenhouse

To reduce the severity of climate change, it’s not enough to just curb the rise in emissions –technologies that actively pull more CO2 out of the atmosphere will also be vital. To that end, a new CO2-filtering plant has just opened up near Zurich.

If the approach can be replicated on a large scale, it would be a game-changer

Tweaked titanium turns CO2 into solar fuel

Dcientists at the University of Central Florida have come up with synthetic material that draws on visible light from the sun to produce solar fuels, sucking harmful CO2 out of the air in the process.

Crystals of CO2 drawn from the air

Carbon capture technology typically takes the form of sponge-like materials that are used to trap excess CO2 at the places it is released. Now, scientists have created a means of drawing it right out of the ambient air – and the technology involves using a liquid to turn the CO2 gas into crystals.

Rice University researchers have used nitrogen-doped graphene quantum dots to convert carbon dioxide into liquid hydrocarbons like ethylene and ethanol, for use as fuel

Graphene quantum dots can convert CO2 into liquid fuels

The wonder-material graphene may have a new trick to add to its resume: converting carbon dioxide into liquid fuels. A team at Rice University has used nitrogen-doped graphene quantum dots to create ethylene and ethanol, with stability and efficiency close to that of electrocatalysts like copper.

Scientists have developed a thin, bubble-like membrane which could help filter CO2 out of flue gas

Bubble-like "Memzyme" increases speed and efficiency of carbon capture

Capturing carbon emissions at the source is an important weapon in the fight against climate change. Now scientists have developed an efficient low-cost technique that makes use of an ultra-thin membrane, like a bubble, to filter CO2 out of flue gas.

Could a new method of carbon sequestration hold the key to battling climate change?

Quickfire carbon capture method turns CO2 into solid rock within two years

A new method of carbon sequestration could seriously fast-track the process. Injecting carbon dioxide into volcanic rocks was found to turn the gas into a solid within two years, which is a much shorter timeframe than the centuries or millennia that the current consensus suggests.
