Carbon Sequestration

This strange white paste might not look like much, but it could not only solve the sand shortage, but make the cement manufacturing process absorb carbon dioxide instead of emitting it. Scientists grew this stuff out of seawater, electricity and CO2.

Using principles from rocket science, researchers have created carbon with a record-breaking surface area. The material can soak up about twice the amount of CO2 as current activated carbon materials and has impressive energy-storage capabilities.

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.

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.

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.

"Artificial leaf" systems could play a key role in the fight against climate change, and a team of engineers has just picked up the pace with a solution that captures carbon dioxide at 100 times the rate of current technologies.

Researchers have proposed a fascinating way to eliminate CO2 in the notoriously hard-to-abate shipping sector. The ships would use existing marine fuels, run through solid oxide fuel cells, and all CO2 would be stored back in a partitioned fuel tank.

Scientists are working on a protective carbon-negative coating for buildings, that would be produced by artificial cells in a process similar to coral production.

A team of researchers has discovered several potential uses for "dry water," including as a storage medium for carbon dioxide gas.
