Section 3 of 5CCU: Carbon as Raw Material
CO₂ utilization (CCU) treats carbon not as waste but as a valuable feedstock—a circular economy for carbon. With energy input (usually renewable electricity or green hydrogen), CO₂ can be transformed into fuels, chemicals, polymers, and building materials. The market is real: $300B+ annually. Urea fertilizer has consumed CO₂ for 100+ years (0.73 t CO₂/t urea). Enhanced oil recovery injects 80 Mt CO₂/year to boost production. New pathways are emerging: synthetic fuels (e-methanol, SAF), CO₂-based polymers (polycarbonates, polyols), and mineralized concrete. But scale is the challenge—global CCU today uses <300 Mt CO₂/year vs. 40 Gt emitted. Most pathways are energy-intensive and only temporary CO₂ storage (fuels release CO₂ when burned). Durable products (polymers, concrete) and renewable energy inputs are key to climate impact.

CH₃OHFischer-TropschCH₄✓ Climate-Positive CCU
- •Durable products: Polymers, concrete store CO₂ for decades
- •Renewable energy: Green H₂ + renewable electricity = net negative
- •Displacement: Replace fossil feedstocks with CO₂-based alternatives
⚠️ CCU Limitations
- •Fuels are temporary: CO₂ released again when burned
- •Energy intensity: Requires 2-5x energy of fossil equivalent
- •Small scale: CCU <1% of emissions—storage is essential
💡 Key Insight
CCU is NOT a replacement for CCS—it's a complement. Fuels and chemicals can use ~1 Gt CO₂/year economically. The remaining 10-20 Gt must be permanently stored underground. Think of CCU as high-value niche markets, not bulk disposal.
