This is just interesting, Baofeng energy announced yesterday that it started work on the largest ever olefin plant in the world with annual production of 3 million tons. Of which, 400k ton will be produced from green hydrogen powered by wind/solar. I'm not clear how much of that is just hydrogen, but this is possibly the largest ever green hydrogen project. Promises to save 6.31 million ton of carbon vs all coal solution. Other projects I've seen like Sinopec's 30k ton a year green hydrogen project only promises to save 1.4 million ton of carbon. So this is quite huge in hydrogen production and carbon emissions saving. Even so, most of the project is still produced by coal.
Overall, Baofeng here aims to produce 5.7 million t of Olefin a year by the time all of its plants are finished.
I actually have never heard of Baofeng or Olefins before today, but it's fascinating to read this. Looks like Chinese fossil fuel companies are increasingly getting into chemical plants and starting to use some renewable energy along the way.
While startup cost is higher, the eventual savings from green H2 should make it more economical than even coal. After all, it sources domestically made solar/wind/electrolysis technology and produces electricity for almost nothing. There is also no pollution to worry about.
