For many years, carbon dioxide has been released into the atmosphere as pollution. But we might have to change the way we think about this greenhouse gas and see it instead as a valuable resource in our energy production. The reason for this is that researchers can transform the greenhouse gas into clean and sustainable methane gas that can subsequently be stored and distributed through our existing natural gas grid.

Researchers from the Department of Engineering at Aarhus University are behind the world’s most comprehensive pilot tests of high-temperature electrolysis, and the technology seems promising. In just a few years, it will be possible to roll out the technology throughout Denmark. It will cover one-tenth of our total energy need, while considerably reducing emissions of carbon dioxide into the atmosphere.

Researchers from Aarhus University transform carbon dioxide into green super gas

The primary ingredients are water, power from wind turbines and a large amount of carbon dioxide that would otherwise have to be released straight into the atmosphere. The result is an artificially produced version of natural gas with a huge green potential.
