Range-bar chart of seven carbon removal methods showing cost per ton today vs. at 2¢/kWh electricity, sorted by how much each method compresses. Direct air capture shows the largest compression, $400–1,000 today to $80–200 at cheap electricity. Nature-based methods hold at $15–100 in both because electricity is not the binding input. Energy-intensive methods (DAC, Ocean Alkalinity, Mineralization) are marked with an amber dot.
