Carbon capture and storage

Carbon capture and storage

International bodies and the UK’s Climate Change Committee advise that carbon dioxide capture and storage (CCS) will be needed for Scotland to meet its climate targets.  

The use of CCS can, for example, help to reduce emissions from industries that are hard to decarbonise – like steel or cement production – but which make important products that will still be needed in our net zero future.   

The geology of the seabed around Scotland is well suited for storage  of carbon dioxide (CO2) and other gases.  

A working CCS infrastructure will create clean, sustainable industrial opportunities in Scotland which can lead to wider benefits – such as job creation – across the country. 

How it works 

CO2 is captured from various sources, such as cement production or fermentation processes, then compressed and either piped or shipped to an offshore storage location.

The compressed CO2 is then injected deep (> 1km) beneath the seabed into a layer of porous rock, like sandstone. There, it displaces water and fills pores within the rock, where it becomes trapped. Several layers of caprock prevent the CO2 from moving up through the rock layers to the seabed.

Roughly one half of Scotland’s potential storage capacity is within 15 kilometres (approximately 10 miles) of existing pipelines on the seabed, which can be re-used to transport CO2  to those areas. 

Scotland’s capacity for storage of this kind represents 75% of the UK’s total capacity. 

How we contribute 

Crown Estate Scotland is helping to develop the industry, working closely with companies, government and communities. 

This includes: 

  • bringing new development opportunities to market by leasing areas of the seabed and managing the associated seabed rights 
  • funding research and technical studies to help establish the sector (e.g. Reframing the value case for CCS
