Capture6 develops integrated carbon dioxide removal and brine-to-freshwater recovery technology that captures atmospheric CO2 emissions, converts brine waste into usable freshwater, and produces green chemicals. Its Monarch project, currently in demonstration in Palmdale, California in partnership with the Palmdale Water District, is designed to process brine from a 0.68 MGD purification plant. Once scaled in Phase 2, Monarch is expected to remove about 25,000 tons of CO2 per year and recover roughly 400,000 m³ of freshwater annually, while lowering regional brine disposal costs by up to 40%. The company has secured project-level, non-recourse financing to advance Phase 2 and previously raised $27.5 million in earlier funding. Beyond Monarch, Capture6 is pursuing a global pipeline of projects including sites in Western Australia, South Korea, the U.S. Midwest, and the United Arab Emirates. The company positions its offerings to address both climate targets and regional water stress through commercial deployments.
