Carbon capture and storage: where should the world store CO₂? It’s a moral dilemma

[Newspaper opinion] To give carbon storage sites the greatest chance of success, it makes sense to develop them in places where the geology has been thoroughly explored and where there is lots of relevant expertise. This would imply pumping carbon into underground storage sites in northern Europe, the Middle East and the US, where companies have spent centuries looking for and extracting fossil fuels. On the other hand, it might be important to develop storage sites in economies where the current and future demand for carbon capture and storage is greatest. The regions with the best prospects are not often those with the greatest expected need. [Open access]
