A major consideration is the kind of crop you’d grow to feed a wide-scale BECCS system. That would probably be switchgrass or Miscanthus, another kind of grass, neither of which need as much water or added nutrients as a crop like corn. “They’re quite efficient,” says David Lawrence, a climate scientist at the National Center for Atmospheric Research and coauthor of the new paper. They’re also perennial crops, so you don’t need to plant and till the ground all the time. “But in the context of the study, we found that despite that, we still are seeing increases in water stress and degraded water quality,” Lawrence adds. “And that
