BEFORE
Where does ocean alkalinity enhancement stand today: who's buying, is it accelerating, and how solid is the science?

Ocean alkalinity enhancement is moving from lab to market. Microsoft agreed to buy 350,000 tonnes from Ebb Carbon, and Frontier has backed Planetary in a deal worth about $31M. Interest from corporate buyers is clearly growing.

On the science, results are promising but early: a small number of field trials, with most work still in models and lab studies. Policy support for the pathway remains unclear.
