Climate's magic rabbit: Pulling CO2 out of thin air

While CO2 concentrations are now higher than they have been in at least 800,000 years, the gas still only accounts for a tiny 0.04% of our atmosphere.

However, extracting carbon dioxide from well mixed air is not just technically difficult, it's expensive as well.

A Clean Energy’s Dirty Little Secret

Discarded solar panels are piling up all over the world, and they represent a major threat to the environment. Clean energy may not be so clean after all.

A new study by Environmental Progress (EP) warns that toxic waste from used solar panels now poses a global environmental threat.

Post-Kemper question: Is 'clean coal' dead?

The possible end of Southern Co.'s flagship "clean coal" project in Mississippi isn't the death knell for carbon capture and sequestration technology, industry analysts say.

Instead, the problems at the Kemper County Energy Facility — which state regulators want to turn into a natural gas plant after years of delays and cost overruns — resulted from a unique series of events and a coal gasification system that was scaled up too fast.

Has an Anglo-Indian project finally cracked carbon capture?

Derided as scientifically unsound and prohibitively expensive, carbon capture and utilisation (CCU) − the process by which carbon dioxide (CO2) is separated from industrial pollutants and converted into commercially viable products – has failed to gain serious traction since trials began 10-15 years ago.

Now however, Carbon Clean Solutions (CCSL), a London-based specialist in carbon separation technology, is set to change all that.
