Technological OCDR I — Ocean Alkalinity Enhancement
We cross from growing life to speeding up chemistry. It buys the most durable storage in the series — and, for the first time, an MRV problem that starts to look solvable . Part 5 of 7 The first four parts stayed in the ocean's living engine — restoring, growing, and feeding the organisms that pull carbon down. Now we cross into the Technological category, where the logic flips. Instead of coaxing biology, these approaches accelerate the ocean's own chemistry and physics — the slow, planetary machinery that has regulated atmospheric CO₂ for hundreds of millions of years. The first and most mature of them is Ocean Alkalinity Enhancement , or OAE. And it is where the measurement problem that haunted the natural approaches finally begins to loosen its grip. The chemistry: rebuilding the ocean's buffer Ocean alkalinity enhancement — adding alkaline minerals to seawater to lock CO₂ away as bicarbonate. Start with why the ocean can absorb CO₂ at all.
