Nonlinear CDR uses fast‑growing Ulva seaweed cultivated in controlled, land‑based tank systems to capture atmospheric carbon dioxide through photosynthesis. The harvested biomass is charred to create a stable, permanent carbon store, and the resulting material is reused to build the next generation of growth tanks, enabling a self‑scaling carbon removal process.

Problem
Current carbon removal methods often rely on large-scale, land-intensive agriculture or oceanic cultivation, which face challenges such as variable climate, high water usage, and limited scalability, making it difficult to capture atmospheric CO₂ at the volumes needed to mitigate climate change.
Solution
Nonlinear CDR captures atmospheric CO₂ by cultivating fast‑growing Ulva seaweed in controlled, land‑based tank systems. The tanks provide optimal, season‑independent conditions that enable Ulva to double its mass roughly every two days, maximizing photosynthetic carbon capture. Harvested biomass is then thermally converted (charred) into a stable carbon form for permanent storage. Materials derived from the harvested Ulva are recycled to construct new tank components, allowing the system to self‑scale and expand its carbon removal capacity without proportional increases in external inputs.
Target Audience
Primary customers are carbon offset providers, climate‑focused enterprises, and governments seeking verifiable, permanent carbon removal solutions at scale.
