Gas Liquids Engineering has finished detailed engineering for Enhance Energy's Origins carbon capture and storage (CCS) hub, the engineering contractor announced, advancing the project toward procurement and a final investment decision.

The detailed engineering package is the last pre-construction deliverable in a typical CCS development sequence, converting front-end engineering and design (FEED) into the construction-ready specifications contractors use to price and build. Completing the package positions the project to firm up long-lead equipment orders, lock construction contracts and close project financing on a defined technical scope.

Origins is structured as a CCS hub — the dominant project model for industrial decarbonization in North America — aggregating CO2 from multiple emitters along shared gathering pipelines and routing it to a common injection point, usually a depleted reservoir or saline aquifer where it is permanently sequestered under Class VI (US) or analogous provincial permits.

Gas Liquids Engineering (GLE) is a Calgary-based engineering firm that specializes in CO2 capture, dehydration, compression, pipeline transport and injection facility design. Completion of detailed engineering signals the Origins hub has crossed the threshold where most design risk is retired, leaving remaining uncertainties tied to execution, regulatory permitting and capital stack closure.

What comes next for the Origins hub?

With detailed engineering complete, the project is positioned to advance on three concurrent workstreams: long-lead procurement, regulatory close-out and final investment decision (FID). Class VI well permits in the US, or their provincial equivalents in Canada, typically dictate the project schedule because drilling authorization must precede injection and storage operations.

Why detailed engineering matters in CCS

Detailed engineering is the stage where project economics and risk profile crystallize. The phase is particularly sensitive for CO2 infrastructure because:

• Pressure, temperature and phase behaviour of dense-phase CO2 drive material selection, pipeline routing and compressor sizing
• Impurity tolerance in the captured stream dictates the specification of dehydration and treatment units
• Injection well design must reconcile reservoir pressure limits with the plume management plans regulators require

Retiring these design variables before FID reduces the cost-overrun risk that has affected several CCS projects globally over the past five years.

Open access as a hub model

Hub configurations spread infrastructure cost across multiple emitters, improving unit economics but adding complexity around CO2 custody transfer, allocation rules and tariff structures between shippers and storage operators. The model has largely replaced the single-source, single-sink configurations that characterized earlier CCS developments.

The next publicly observable milestone for the Origins hub will be either an FID announcement from Enhance Energy or a permitting action from the relevant regulator — whichever comes first.
