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.

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.

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.

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.

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.

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.

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.

A UCLA team has developed a technology to turn sequestered carbon dioxide into concrete. The researchers would like to see their technology applied in power stations, which are massive sources of emissions.

Scientists at Queen's University Belfast have devised a class of liquids that feature permanent holes at the molecular level, in a development that could help manipulate gases in new and effective ways.

Scientists from the University of Florida have found that a bacterium found in deep-sea regions could help convert C02 into bicarbonate and so help reduce emissions. More research is needed on how to scale it up to an industrial setting.
