Carbon Dioxide

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.

Engineers at UIC have developed a device that can efficiently convert captured carbon dioxide into ethylene, a plastic precursor material. When run using renewable energy, the technique could make for net negative emissions in plastic production.

Even slight adjustments to how we make cement and concrete can have a big impact on their environmental footprint, and as research continues to show, scientists working in this space are not short of ideas.

The James Webb Space Telescope has clearly detected carbon dioxide in the atmosphere of an exoplanet for the first time. The find marks a milestone for the telescope’s goal of analyzing the air of distant planets to aid the search for alien life.

Leaves are impressive machines, converting sunlight, carbon dioxide and water into energy. Cambridge scientists have now created artificial leaves that can float on water, tapping into sunlight above it and water below to efficiently produce fuels.

In less than 18 months, Energy Dome has opened the first of its remarkable grid-level energy storage plants. These "CO2 batteries" store renewable energy over long periods and release it quickly, at less than half the cost of big lithium batteries.

Climate scientists have reported the highest levels of carbon dioxide ever recorded in the atmosphere. The latest in a series of record-breaking years saw levels 50 percent higher than pre-industrial times, a concentration not seen 4 million years.

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.

The last chapter in a trio of reports from the UN's top climate scientists has landed, with the authors noting some reasons for optimism, mounting an argument that the window is still open for meaningful action to limit warming to around 1.5 °C.

If mosquitoes seem to love you but ignore the person sitting next to you, the color of your clothes might be to blame. New experiments reveal that certain colors attract hungry mosquitoes, which could be used to design new traps or repellents.

"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.

A new method quickly converts carbon dioxide into solid carbon, which can be stored indefinitely or turned into useful materials. The technology works by bubbling CO2 up through a tube of liquid metal, and could be used at the source of emissions.
