11. Conclusion

To succeed on a large scale, the deployment of capture-storage technologies requires :

• R work to develop new, more economical and safer CO ₂ capture and storage techniques;

• industrial demonstrators to validate and improve various concepts;

• a regulatory framework and economic incentives to facilitate investment in this sector.

Actions to ensure the social acceptability of these solutions are also essential.

The capture/storage sector is presented as a transitional solution, which should make it possible to lower CO ₂ emissions from the use of fossil fuels for as long as it takes for alternative energies to take over....
