Tip Meckel, a lanky research scientist at the University of Texas' Bureau of Economic Geology, has worked for most of the past decade and a half to map a roughly 300-mile-wide arc of the Gulf Coast from Corpus Christi, Texas, through Port Arthur to Lake Charles, Louisiana. Though he's the grandson of a refinery worker and the son of an oil consultant, his interest isn't in extracting more petroleum from this rock. Instead, he has devoted most of his career to figuring out how to turn it into a commercial dump for CO2. The idea is that major emitters will hoover up their own carbon waste, then pay to have it compressed into liquid and injected back down, safely and permanently, into the same sorts of rocks it came from—carbon capture and sequestration on a scale unprecedented around the globe, large enough to put a real dent in climate change. Suddenly, amid surging global concern about the climate crisis, some of the biggest names in the petroleum industry are jumping in. Jeffrey Ball | Energy & environment writer |
