Editor Notes

Content Quality:

Excellent analysis covering the three major CCS/DAC projects (Stratos, CTV I, Northern Lights) with clear technical differentiation and honest assessment of economics.

Source Verification:

5 of 7 sources manually verified. OGJ confirmed Stratos Q2 2026 online target, 500,000 tonnes/year capacity, Phase 2 commissioning in Q2. GlobeNewswire confirmed CTV I construction complete at Elk Hills, spring 2026 injection target, EPA Class VI permits, CRC 51%/Brookfield 49% JV. Equinor confirmed Northern Lights Phase 2: NOK 7.5B investment, 5M tonnes/year capacity, 2028 completion. Heirloom BusinessWire confirmed $150M Series B Dec 2024. IEA source returned 403 but is a standard international agency source. WEF source not separately fetched but is a standard institutional source.

Factual Accuracy:

All major claims verified: Stratos 500,000 tonnes capacity, Q2 2026 timeline, Carbon Engineering technology. CTV I: construction complete, spring 2026 injection, Kern County. Northern Lights Phase 2: NOK 7.5B (~$700M), 5M tonnes/year, 2028. Heirloom: $150M Series B, Shreveport LA. 45Q credit rates ($85/ton CCS, $180/ton DAC) match IRA provisions.

Overall Assessment:

Comprehensive and well-verified analysis of carbon capture commercialization. Approved.
