Norway inaugurates undersea vault to store CO2 safely
The Northern Lights project plans to take CO2 emissions captured at factory smokestacks in Europe and inject them into geological reservoirs under the seabed.
The aim is to prevent the emissions from being released into the atmosphere, and thereby help halt climate change.
The captured CO2 is compressed, liquefied and pumped deep down into the sub-surface to isolate the greenhouse gas from the atmosphere.
It will have an initial capacity of 1.5 million tonnes of CO2 per year, before being ramped up to five million tonnes in a second phase if there is enough demand.
