World's first commercial sCO2 power generator begins operation in China (youtu.be)

The world's first commercial supercritical carbon dioxide power generator has begun operation in Southwest China's Guizhou Province. It is viewed as a milestone in changing the power generation mode relying on steam for more than a century. China calls the project "Chaotan-1." CGTN's Zheng Yibing speaks to experts from Nuclear Power Institute of China about it.

Why is this such a big deal? Because traditional power generation relies on steam driven turbines, even in nuclear reactors. The thermodynamic losses in the process are substantial and a major barrier to more efficient power generation. With superheated CO2 as the medium, the efficiency of the energy conversion can be greatly increased and losses reduced.

I agree, the terminology can be confusing.

If you get the chance, you can look up what a supercritical transition looks like, because it's really cool. I still remember to this day my first semester in uni one of the coolest demonstrations was seeing a fluid go supercritical, and you can really see the border between the liquid and the gas start to blur and eventually just disappear completely.

Just watched the Steve Mould video; very enlightening.
