![]() Talal Hasan was working in Oman’s sovereign investment arm when he read about the country’s coast having the largest “dead zone” in the world, a major contributor to which was CO2 emissions being absorbed by the sea and gathering there. Peridotite is normally found miles below sea level, but on the easternmost tip of the Arabian peninsula, specifically the northern coast of Oman, tectonic action has raised hundreds of square miles of the stuff to the surface. In fact this has occurred at enormous scales throughout history, as witnessed by large streaks of calcite piercing peridotite deposits. A naturally occurring stone called peridotite reacts with the gas and water to produce calcite, another common and harmless mineral. The process of mineralizing CO2 is well known among geologists and climate scientists. One promising approach turns the gas into an ordinary mineral through entirely natural processes 44.01 hopes to perform this process at scale using vast deposits of precursor materials and a $5 million seed round to get the ball rolling. ![]() Reducing global greenhouse gas emissions is an important goal, but another challenge awaits: lowering the levels of CO2 and other substances already in the atmosphere. ![]()
