Energy Dome Secures Funding, Partner For New CO2 Energy Storage Projects
The title of this post is the same as that of this article on Renewables Now.
This is the first paragraph.
Energy Dome SpA announced on Tuesday that it has closed a funding round securing USD 11 million (EUR 9.7m) to finalise the construction of a demonstration 2.5-MW/4-MWh carbon dioxide (CO2) battery storage project in Sardinia and to speed up business growth.
Note.
- It appears that Energy Dome has weaponised carbon dioxide against climate change.
- Providing 2.5 MW for over an hour and a half is an impressive performance.
- I think this project has the style we associate with Italy and Italians.
I have found their website at energydome.com and behind their energy storage system is unusual technology.
Their web site says this about their choice of storage medium.
CO2 is the perfect fluid to store energy cost effectively in a closed thermodynamic process as it is one of the few gases that can be condensed and stored as a liquid under pressure at ambient temperature. This allows for high density energy storage without the need to go at extreme cryogenic temperatures.
That is breathtakingly simple!
The main tank for the gaseous carbon dioxide is an inflatable dome and the liquid carbon dioxide is stored in steel tanks.
A turbine -compressor moves the carbon dioxide between gaseous and liquid states storing it appropriately.
It is very impressive! And I suspect extremely affordable!
