Carbon Sequestration
-
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.
-
The US state of Wyoming is set to welcome the world’s largest direct air capture plant for the removal of atmospheric carbon dioxide. Called Project Bison, the facility is expected to suck up five million tons of CO2 each year by 2030.
-
Swiss outfit Climeworks has today broken ground on its second direct air capture plant in Iceland, and one that marks significant progress in its ambitions of removing gigatons of CO2 from the atmosphere each year by 2050.
-
Carbon capture could be an important tool to fight climate change. Researchers have now developed a new compound that can reportedly remove carbon dioxide from ambient air with 99 percent efficiency and at least twice as fast as existing systems.
-
Direct air carbon capture is currently far too costly – but this London company says it can do it at enormous scale for a tenth the price, using engineered algal blooms in ponds located near desert coastlines. Oh, and it'll de-acidify the ocean, too.
-
An XPrize competition designed to develop solutions to the mounting levels of carbon dioxide in the atmosphere has progressed to its next phase, with 15 teams from around the world each awarded US$1 million to continue developing their technologies.
-
"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.
