Biological vs chemical carbon-negative processes: permanence, cost, and scalability compared

Side-by-side evaluation of biological carbon removal approaches (engineered algae, enhanced weathering microbes, soil carbon biotech) versus chemical processes (DAC, mineral carbonation). Biological pathways offer costs of $50–150 per tonne CO₂ but face permanence challenges, while chemical routes achieve 1,000+ year storage at $250–600 per tonne.

Climate biotech carbon-negative processes costs in 2026: investment, unit economics, and path to profitability

Detailed cost and ROI analysis for carbon-negative biotech ventures including engineered algae, methanotroph platforms, and microbial carbon mineralization. Early-stage companies require $5–30M in R&D before pilot deployment, with carbon credit revenues of $50–200 per tonne needed to reach breakeven within 7–12 years.
