The largest carbon dioxide capture program in the world, the CASTOR project, set up with funds released by the EU under its Sixth Framework Program (6e PC), inaugurated the 15 March at the Central Elsam coal mill, near Esbjerg (Denmark). This project is a large-scale trial to examine how to modify plant releases to extract carbon dioxide, a greenhouse gas.

I have serious doubts about the burial of CO2.
Besides that the CO2 will find many flaws where to escape, I wonder how not to worry about the risk of massive acidification of soils above the landfill, which would turn the surface of the site into a real desert in a few years ...
It's nice to hide the dirt under the carpet, but it does not solve the problem and it could be dangerous ...

Nature does this very well, and to the eye: thanks to the energy of the sun, CO2 is stored in biomass.

So, if we have to summarize the burial of CO2, it is Rulian who summarizes:
- Lack of knowledge of the geology of the field
- Chemical attack of the walls by CO2 (which in combination with moisture becomes carbonic acid)
- Major industrial risk in case of earthquake: thousands of people asphyxiated by the pocket of thousands of m3 CO2 escaping.
There's something even more stupid in the CO2 landfill.
It means capturing the CO2 (in particular filtering the CO2 in the fumes, etc.), then compressing it "under the feet" (digging / finding / adapting an "adequate" cavity, generating the burial pressure, etc.) , it generates in itself even more CO2 ... without any guarantee that the CO2 buried the rest.

The only catch of the CO2 a little serious, as well economically as ecologically, it is that by microalgae (or other process that VALORIZES it) ...Because instead of being an economic dry waste, the capture of CO2 creates an industrial wealth ...
The other projects, I think it's just to show that "they know" how to do ... to reassure the crowds and spend billions in R&D ...
