There is broad consensus on the key role that carbon dioxide (CO2) capture, transport, and storage (CCTS) systems will play in mitigating climate change, either by removing CO2 from the atmosphere and storing it permanently or by avoiding CO2 emissions generated by point sources, especially from hard-to-abate sectors (e.g., waste-to-energy, cement, shipping or aviation). Although CCTS is ready to be implemented from a technical standpoint, the legal and regulatory framework required for its implementation and regulation could be further improved. In this article, we summarize and critically discuss the provisions of the Convention for the Protection of the Marine Environment of the North-East Atlantic (the ‘OSPAR Convention’), and of the London protocol, as well as of the European CCS and ETS Directives. With a focus on the European Economic Area, we highlight existing gaps and hurdles that should be tackled in view of the large-scale deployment of CCTS. Furthermore, as the legal landscape for CO2 transport and geological storage is evolving rapidly, we provide an overview of recent clarifications on aspects of the existing legislation and a summary of new proposals presented by the European Commission in this space.

Depleted oil fields in the Gulf of Suez (Egypt) can serve as geothermal reservoirs for power generation using a CO-Plume Geothermal (CPG) system, while geologically sequestering CO. This entails the injection of a substantial amount of CO into the highly permeable brine-saturated Nubian Sandstone. Numerical models of two-phase flow processes are indispensable for predicting the CO-plume migration at a representative geological scale. Such models require reliable constitutive relationships, including relative permeability and capillary pressure curves. In this study, quasi-static pore-network modelling has been used to simulate the equilibrium positions of fluid–fluid interfaces, and thus determine the capillary pressure and relative permeability curves. Three-dimensional images with a voxel size of 0.65  of a Nubian Sandstone rock sample have been obtained using Synchrotron Radiation X-ray Tomographic Microscopy. From the images, topological properties of pores/throats were constructed. Using a pore-network model, we performed a sequential primary drainage, main imbibition cycle of quasi-static invasion in order to quantify (1) the CO and brine relative permeability curves, (2) the effect of initial wetting-phase saturation (i.e. the saturation at the point of reversal from drainage to imbibition) on the residual-trapping potential, and (3) study the relative permeability-saturation hysteresis. The results improve our understanding of the potential magnitude of capillary trapping in Nubian Sandstone, essential for future field-scale simulations.

Techno-economic assessment of post-combustion CO2 capture using aqueous piperazine at different flue gas compositions and flowrates via a general optimization methodology
Pérez Calvo, José Francisco; Mazzotti, Marco (2022)
International Journal of Greenhouse Gas Control
An overall techno-economic assessment of a post-combustion CO2 capture process using aqueous piperazine is presented. A two-step techno-economic optimization approach is developed and implemented. First, two-objective technical optimization problems are solved at different combinations of CO2 capture efficiencies and CO2 concentrations in the flue gas, which aim at minimizing the specific equivalent work while maximizing the volume-based productivity of the capture process. Increasing minimum specific reboiler duties between 2.4 and 2.9 MJthkgCO2captured−1 are obtained for decreasing flue gas CO2 concentrations between 33 and 4 vol%, on a dry basis, with absorber packing heights below 10 m. Then, costs are computed at the technical optimal conditions as a function of the CO2 capture efficiency, flue gas flowrate and CO2 concentration. As a result, maps of minimum cost of CO2 captured, of minimum cost of CO2 avoided, and of minimum cost of CO2 generated by the CO2 point source are obtained, as well as of the associated optimal operating conditions and performance indicators of the capture process, which allow to assess the economic feasibility and performance of the capture process under different cost scenarios and assumptions when applied to different flue gas compositions and flowrates typical of industrial CO2 intensive point sources.
