Carbon capture: how does CO2 removal work?

With global temperatures still on the rise, even the most sceptical of scientists agree that carbon dioxide removal (CDR) is crucial to meet the Paris Agreement goal of capping global warming below two degrees Celsius.

How not to solve the climate change problem

When politicians talk about reaching "net zero" emissions, they're often counting on trees or technology that can pull carbon dioxide out of the air. What they don't mention is just how much these proposals or geoengineering ...

Using bacteria to accelerate CO2 capture in oceans

You may be familiar with direct air capture, or DAC, in which carbon dioxide is removed from the atmosphere in an effort to slow the effects of climate change. Now a scientist at Lawrence Berkeley National Laboratory (Berkeley ...

Q&A: Removing carbon dioxide from the atmosphere

Radu Custelcean, an organic chemist at the Department of Energy's Oak Ridge National Laboratory, is working with colleagues to develop an energy-efficient and sustainable method for scrubbing carbon dioxide directly from ...

Air-scrubbing machines gain momentum, but long way to go

On a field ringed by rolling green hills in Iceland, fans attached to metal structures that look like an industrial-sized Lego project are spinning. Their mission is to scrub the atmosphere by sucking carbon dioxide from ...
