National Grid has successfully completed test drilling of a carbon dioxide storage site in the North Sea – a major milestone in delivering a storage solution for Carbon Capture and Storage (CCS).
Early indications are that the undersea site 65 kilometres off the Yorkshire coast is viable for carbon dioxide storage and will be able to hold around 200 million tonnes permanently. This is equivalent to taking ten million cars off the road for 10 years.
The drilling is a major milestone in its Don Valley storage work programme funded by an EU grant to advance CCS in Europe. The findings are significant as this type of storage site is common in Europe.
If we take that figure of 200 million tonnes of CO2 and compare it to a reported 35.6 billion tonnes of CO2 emitted globally in 2012, we may easily calculate that the National Grid CO2 storage project would accommodate global CO2 emissions for about two days. So after two days it would be full.
One might ask if that two days respite represents good value for money in terms of CO2-induced global temperature changes. Good value for the well owners no doubt, but good value for us?
