Carbon Sequestration

Researchers at UC Berkeley have invented a material in powder form that adsorbs carbon dioxide with astonishing performance. Just 200 g (a little under 0.5 lb) can suck up 44 lb (20 kg) of CO2, the same as a tree does in a year.

A 3,775-year-old log discovery has lent credence to the idea of burying wood to sequester the carbon it contains. Known as a wood vault, the concept helps keep CO2 out of the atmosphere while allowing the soil to be used for crops and other purposes.

A technique originally developed to combat acid rain has the potential to pull an enormous amount of carbon dioxide out of the atmosphere – while helping to deacidify oceans, restore rivers and boost biodiversity and fish populations.

Tulip trees have been around for millions of years, but a new analysis of their structure has revealed a previously unknown type of wood. The finding could explain why the trees are great at sequestering carbon and help our efforts to do the same.

A new material tackles the carbon problem of concrete production and usage by employing a pretty unusual workforce: cyanobacteria. The bio-cement these micro-organisms help to produce harnesses a process that's existed in nature for 3.5 billion years.

The application of crushed rock to farmers' fields may not only reduce greenhouse gases, it could also boost crop yields by up to 16%. These are the findings of a new study conducted by scientists from the University of Sheffield.

Captura Corporation has developed a revolutionary plan to remove carbon emissions by creating an aquatic purification facility in the middle of the sea. The company intends to extract carbon dioxide from ocean water using only renewable electricity.

Concrete is one of the largest single sources of human-induced carbon dioxide emissions. Engineers at Washington State University have now developed a new method for making concrete that absorbs more carbon than it emits.

Could salt, one of the oldest preservatives around, help keep carbon deep underground for thousands of years? Researchers believe it can, and that it might offer a way forward in containing a gas that's a major contributor to climate change.

After water, concrete is the world’s most consumed material, and concrete production’s impact on the environment is significant. Researchers have discovered that an inexpensive ingredient may be the answer to reducing concrete's climate impact.

While crops do sequester some atmospheric carbon dioxide (CO2) via photosynthesis, they could always use a bit of help. California startup Andes is aiming to provide that help, by putting carbon-capturing microbes in the soil of farmers' fields.

Denmark is moving forward with Project Greensands, an initiative that will take huge quantities of captured carbon out to an oil rig in the North Sea, and pump it down to sequester it in the sandstone formations that once held oil and gas.
