Here you go - Australian TEchto save the day...Don't need to go down the renewables path any longer & waste trillions upon trillions of dollars.
Researchers from Monash University and the CSIRO have set a record for carbon dioxide capture and storage (CCS) using technology that resembles a sponge filled with tiny magnets.
Using a Metal Organic Frameworks (MOFs) nanocomposite that can be regenerated with remarkable speed and low
energy cost, researchers have developed sponge-like technology that can capture
carbon dioxide from a number of sources, even directly from air.
The magnetic sponge is used to remove carbon dioxide using the same techniques as induction cooktops using one-third of the energy than any other reported method.
Associate Professor Matthew Hill (CSIRO and Department of Chemical Engineering, Monash University) and Dr. Muhammad Munir Sadiq (Department of Chemical Engineering, Monash University) led this research.
In the study, published in
Cell Reports Physical Science, researchers designed a unique adsorbent material called M-74 CPT@PTMSP that delivered a record low energy cost of just 1.29 MJ kg-1CO2 , 45 per cent below commercially deployed materials, and the best CCS efficiency recorded.
MOFs are a class of compounds consisting of metal ions that form a crystalline material with the largest surface area of any material known. In fact, MOFs are so porous that they can fit the entire surface of a football field in a teaspoon.
This technology makes it possible to store, separate, release or protect valuable commodities, enabling companies to develop high value products.
"Global concerns on the rising level of greenhouse gas emissions and the associated
environmental impact has led to renewed calls for emissions reduction and the development of green and renewable alternative energy sources," Associate Professor Hill said.
"However, existing commercial carbon capture technologies use amines like monoethanolamine, which is highly corrosive, energy intensive and captures a limited amount of carbon from the atmosphere.
"Our research shows the lowest reported regeneration energy calculated for any solid porous adsorbent, including monoethanolamine, piperazine and other amines. This makes it a cheap method that can be paired with renewable solar energy to capture excess
carbon dioxide from the atmosphere.
"Essentially, we can capture CO2 from anywhere. Our current focus is for capture directly from the air in what are known as negative emissions technologies."
