Low-cost solar PV can turn CO2 into profitable materials enabling negative emissions Low-cost solar PV enables to turn CO2 from an unwanted burden into a precious raw material and sequestered in materials with many applications. This effectively reframes carbon capture, utilization, and sequestration as a monetizable carbon dioxide removal option. Three recent studies on electricity-based carbon fiber, silicon carbide, and graphene aimed at enabling large-scale negative emissions by 2050.
