The facility problem
A large gas plant runs continuous compression, refrigeration and treating loads, today driven by natural-gas engines and turbines that emit CO₂ and NOx from exhaust stacks. Its emissions exposure is rising under federal and provincial methane and carbon rules, while its power demand is not going anywhere.
The proposed project replaces that gas-driven equipment with electric drives powered by on-site oxy-fuel generation, so the plant’s own fuel becomes zero-emission electricity and the combustion CO₂ becomes a captured, compressed stream for sequestration rather than a stack emission.
Problem statement drafted from the public project description; to be validated with the host operator.
Scope of the project
As described publicly by Valverde. Each element is a design intent until feasibility confirms it.
Oxy-fuel generation
Install the CES Direct Steam Gas Generation unit and connect gas-turbine generators to produce electricity from the steam and CO₂ stream.
Facility electrification
Convert natural-gas-driven generators and compression to electric drive, removing their exhaust emissions and consolidating fuel use into the oxy-fuel unit.
Air separation unit
Implement a properly sized ASU to supply the oxygen the combustor requires.
CO₂ compression
Compress the captured CO₂ for transport and geological sequestration.
Grid export
Sell surplus zero-emission electricity into the Alberta grid, subject to interconnection.
Facility upgrades
Upgrade the affected existing facilities so that they operate with zero stack emissions. design target
Milestones and dependencies
Completed
- Host operator engaged; project scope defined at concept level (public)
- Technology basis established: CES DSGG unit under Valverde master licence
- Further completed items to be listed by management verify
Outstanding dependencies
- Load, gas and site data sufficient for a scoped feasibility assessment
- Oxygen supply configuration (on-site ASU sizing or over-the-fence supply)
- Carbon destination: storage site, transport interface, pore-space and regulatory route
- Alberta grid interconnection and export arrangements
- Commercial model and development agreement between the host, Valverde and partners
- Incentive determinations (CCUS ITC, TIER, other) for the specific project — professional review required
Next decision
To be stated by management. The project page will show the date of the next gate and what evidence it requires. verify

How to read the numbers on this project
Every figure attached to this project is one of the following. Where a number is not yet available at that standard, we say so instead of implying completion or scale.
| Item | Type | Current basis |
|---|---|---|
| Electrical output | not disclosed | Capacity basis not published. The CES oxy-fuel solution is designed for roughly 10–100 MW per installation (supplier statement). |
| CO₂ captured | design target | Full capture of combustion CO₂ from the oxy-fuel unit is the design intent. Denominator, downtime and bypass treatment to be defined in feasibility; no measured figure exists. |
| Stack emissions after conversion | design target | Zero stack emissions from the converted equipment is the target; residual emissions from any unconverted equipment are excluded from that statement. |
| Capital and operating cost | not disclosed | No cost figures are published. Comparisons with post-combustion capture are project-specific and will be made in the feasibility study. |
| Fuel flexibility | supplier data | Pipeline gas at this site; CES data for other compositions is not needed for this configuration. |
| Independent assessment | none published | No independently assessed or measured results have been published for this project. |
A two-page project summary matching this page, with a version date, will be available on request once approved. Sensitive models and contracts are shared in a controlled diligence environment, not through a public download.
