## Summary

Dr. Laura Lammers, Founder and CEO of Travertine, explains how her company uses water electrolysis to upcycle sulfate waste (like phosphogypsum) into carbon-negative sulfuric acid while permanently sequestering CO2 in carbonate minerals. She discusses the massive scale of industrial sulfate waste, the business case for fertilizer and mining customers, and the hardware challenges of scaling electrolyzers with divalent ions. Lammers also outlines the path to gigaton-scale carbon removal through enhanced weathering and the impact of the Inflation Reduction Act on green hydrogen and carbon credits.
