The world needs carbon capture technologies if we want Earth to continue to be a tolerable place for humans.

The world emits about 43 billion tons of CO2 a year. So to meet the global-consensus goal of net-zero carbon dioxide emissions by 2050, we need to deploy some game-changing technologies.

That’s where carbon capture comes in!

Removing carbon dioxide from point sources can be a big part of the path to net-zero.

Now, in significant advancement in carbon dioxide capture technology, University of Delaware engineers have found a way to effectively combat the effects of carbon dioxide. Researchers used a novel electrochemical system powered by hydrogen to capture 99% of carbon dioxide from the air.

Environmentally friendly fuel cells work by converting fuel chemical energy directly into electricity.  They can be used in transportation for hybrid or zero-emission vehicles.

Smaller package capable of filtering greater quantities of air

Researchers say that their soda can-sized prototype device is capable of filtering roughly 10 liters of air per minute and can remove 98% of CO2.

Even a smaller electrochemical cell measuring just 2”x 2” could be used to remove roughly 99% CO2 from the air flowing at a rate of approx. two liters per minute.

Their electrochemical system can also be used in transportation to scrub CO2 out of a vehicle’s exhaust.
