Researchers have created a solar-powered reactor that collects CO2 by night and turns it into a useful gas by day.

A new solar-powered direct air capture system not only removes CO₂ from the atmosphere but converts it into syngas, a key ...

As two features elsewhere in these pages illustrate – shining a light on Synata Bio and Solar Foods respectively – companies ...

I’ll finish next week, maybe. Let’s look at how ethanol plants make carbon dioxide. Here’s the big picture. Grind corn up, mix with water, cook it, add enzymes to turn the starches to ...

A group of scientists has developed special CO2-derived carbon nanotubes that can generate sustained plasma almost instantly when exposed to microwaves from a standard microwave oven. Plasma is the ...

Researchers at Cambridge have created a reactor that uses sunlight to convert carbon dioxide into an alternative fuel source.

It takes time for plumes of CO2 from sources such as wildfires to mix evenly into the atmosphere around the world. "The fire emissions in the northern hemisphere were particularly large last year ...

The standard production method for liquid synfuel involves two steps: (1) generating a gaseous mixture of carbon monoxide and hydrogen from CO2 and water; and (2) facilitating chemical reactions ...

The light oil mixture is projected to cut CO2 emissions by 2.5 tons per year. The annual carbon footprint reduction linked to the use of biofuel for steam and diesel locomotives is comparably to ...

Key to its operation, the system reuses the specific mixture of gases generated at the negative electrode (the cathode), which can significantly improve the conversion of CO2 into new valuable ...
