CCUS Vendor Selection: Why Most Feasibility Studies Are Wrong

Most CCUS vendors will pitch you their largest, most expensive solution regardless of your site constraints. This "boil the ocean" approach burns capital and delays progress. Here's how to separate engineering-grade feasibility from vendor hype.

The "Boil the Ocean" Problem

Traditional CCUS vendors approach every facility with the same playbook: design a massive, custom-built system that captures 90%+ of emissions. The problem isn't ambition — it's economics. A custom CCS system costs $7.8M–$15M in upfront CAPEX and takes 18–36 months to deploy.

The right question isn't "can we capture all our CO₂?" It's "what's the most economically defensible capture pathway for our specific emissions profile, timeline, and capital constraints?"

Dilute vs. Concentrated Streams

Most carbon capture technology was designed for concentrated CO₂ streams (80%+): ethanol fermentation, natural gas processing. These streams are straightforward — the CO₂ is already separated from other gases.

Dilute streams (3–5% CO₂) are fundamentally different. Gas data centers, power plants, and gas turbines produce flue gas where CO₂ is mixed with nitrogen, oxygen, water vapor, and trace pollutants. Conventional amine scrubbing fails at these concentrations — the chemistry degrades rapidly in high-oxygen environments.

If a vendor is proposing amine scrubbing for a gas data center, ask to see their performance data at 3–5% CO₂ concentration. If they can't provide it, walk away.
