Builds machines that pull water from air using tailored metal-organic frameworks (MOFs), released by low-grade heat instead of electricity

Data centers will pay to turn their waste-heat problem into water, making metal-organic-framework air-water harvesters economic without grid power

Chemist Omar Yaghi spent two decades turning MOFs from theory into stable materials, work that won the 2025 Nobel Prize in chemistry; Atoco builds water-harvesting products on them. Yaghi, who grew up hauling water for his household in a Jordanian refugee camp, says the goal is moving 'from scarcity to abundance'. CEO Samer Taha says four or five years ago 'we were not really thinking of AI data centers' — the buildout changed that.

In September 2026 Atoco showed a 20-foot off-grid unit in its Irvine parking lot: MOFs adsorb water from air, then release it with heat as low as 100F — the team simulated data-center heat at around 150F. The demo makes up to 300 liters a day; a commercial unit of 1,000 liters a day is in development. Atoco has five on-grid prototype trials with partners in the US and the GCC, is in conversations with major tech companies it would not name about data-center pilots, and hopes to take first orders by the end of 2026.

Data centers pay twice — to disperse waste heat and to buy cooling water — and Atoco returns 'the same product that is causing the issue'.

Big tech's water-positive-by-2030 pledges give the startup named prospective customers with budgets already committed.

The MOFs are engineered to 'like water but not love it', releasing at 100F so waste heat nobody wants can drive the cycle.

Founding science is credible and third-party checked: Yaghi's MOF work won the 2025 Nobel Prize in chemistry.

Solve two paying problems with one machine: if your process runs on low-grade heat, someone else's expensive waste stream is your free energy input.

As of 2026-10-07 the 300-liter-a-day demo has run all summer in an Irvine parking lot, five on-grid trials are underway with US and GCC partners, a 1,000-liter-a-day commercial unit is in development, first orders are targeted for end-2026, and data-center pilot talks with unnamed major tech companies are open. The $2-per-ton cost target is three to five years out.
