SEPTEMBER 2021 - CCS NETWORKS IN THE CIRCULAR CARBON ECONOMY: LINKING

In part 1, using a single methodology to characterise global emissions and Pipeline and compression networks require the basins, we performed a high-level, regional analysis development of cost models for piping and compression identifying potential CCS networks by linking suitable systems for the specific country and local costs of energy storage to intense emissions centres across the globe. [...] The project has injected 5 million tonnes of CO2 since 15 CCS NETWORKS IN THE CIRCULAR CARBON ECONOMY New Zealand’s major emissions hubs are proximate to The CO2 storage potential of the Islands of Oceania the suitable Taranaki Basin. [...] Onshore emission hubs will of Venezuela emission sources – mainly from power 22 CCS NETWORKS IN THE CIRCULAR CARBON ECONOMY generation and oil and gas processing and refining – Both Venezuela and Trinidad and Tobago have complex can likely be stored in depleted oil and gas fields in the tectonic histories. [...] A sketch of this land is shown in Figure 16: 28 CCS NETWORKS IN THE CIRCULAR CARBON ECONOMY Each “X” represents a CO2 capture source, with the The network design is intended to be a first-pass number representing the annual volume in millions of attempt to minimise the overall transport system cost to tonnes per annum (Mtpa). [...] The If the CO2 source is in the 0.3-0.5 Mtpa range, the choice compression station should be located at the spot of compression arrangement will need to be on a case- where the total costs of all gas-phase lines supplying it by-case basis.
