The super sponges that could help fight pollution

A man-made, porous ‘super sponge’ that soaks up pollutants before it hits the atmosphere could be our latest weapon in the fight against global warming.

A lab-grown manmade sponge may soon transform many areas of everyday life.

Metal Organic Frameworks (Mofs) are the world’s most porous materials. They can be used as efficient and long-lasting filters to clean up pollution, or to soak up and hold natural gas, water, hydrogen, or carbon dioxide.

Dr Matthew Hill, at Australia's Csiro, believes the new materials he is developing could revolutionise the future of power generation and greenhouse gas clean-up.

Small quantities could be used to absorb the CO2 created by burning fossil fuels, locking it away and stopping it from entering the atmosphere. Then they can be made to release it later, perhaps in a useful way, using just sunlight.

How much of the stuff would you need to make a power plant carbon-zero? Watch the video above to find out.
