John Kang Liquidmetal | CO2 Storage
John Kang Liquidmetal Technologies, Inc. has always believed in the potential of Liquidmetal. He has talked extensively in the past about its advantages, as well as how it can be harnessed by different industries. Today, new research echoes just how helpful it can be in resolving climate change.
How can Liquidmetal help with greenhouse gas?
Recent research published in Nature Communications by the RMIT University in Melbourne, Australia, shows how John Kang Liquidmetal can be harnessed to reduce the impact of climate change. According to the researchers, this innovative metal can provide an alternative to permanently and safely remove greenhouse gas from the atmosphere.
This involves carbon capture and storage (CCS) or the technology of capturing CO2 “emissions produced from the use of fossil fuels in electricity generation and industrial processes, preventing the carbon dioxide from entering the atmosphere,” says Carbon Capture & Storage Association. There have been many environmental concerns about existing CCS processes, which involve compressing the CO2 into a liquid form and injecting it underground on a suitable site. Many were concerned about possible leaks, as well as the economic viability of this process.
As such, the researchers looked into converting the CO2 into a solid instead. They believed that it would be akin to turning back time, since turning C02 back into coal and burying it seems like rewinding the process of emissions. However, it has only been successfully converted to coal at extremely high temperatures, making it yet another industrially and environmentally unviable option.
This is where John Kang Liquidmetal came in handy. According to the researchers, “By using liquid metals as a catalyst, we’ve shown it’s possible to turn the gas back into carbon at room temperature, in a process that’s efficient and scalable.”
Lead author Dr. Dorna Esrafilzadeh is credited for developing the technique that allowed the researchers to capture and convert C02 into storable solid carbon. To do so, The Engineer writes, “The researchers designed a liquid metal catalyst with specific surface properties that made it extremely efficient at conducting electricity while chemically activating the surface.” As a result, the CO2 in the container slowly converts into solid carbon flakes. John Kang Liquidmetal says the flakes are naturally detached from the surface, so it is possible to continuously produce the storable solid.
The study reveals an added benefit of producing synthetic fuel as a by-product, as well as the carbon’s ability to become a supercapacitor. In the future, these two benefits can be helpful in producing more energy.
As for John Kang Liquidmetal, Kang has always known that the metal can be helpful in a number of ways. He says, “Liquidmetal has a number of unique properties that make it a desirable material, the most notable of which are the following: high resistance to breakage under tension (high tensile strength), resistance to destruction caused by its reaction to the environment it is exposed to (corrosion resistance), remarkably high coefficient of restitution (COR) which gives it an almost elastic quality that allows for the gradual release of stored energy, and excellent anti-wearing properties.”
