Sesame Solar out of Jackson, Michigan, makes mobile nanogrids that generate off-grid power within 15 minutes using solar, green hydrogen and battery storage.
The nanogrids consist of a retractable solar array that charges a battery system to produce green hydrogen via electrolyzers. The hydrogen system needs deionized water to run, which Sesame keeps on hand during deployments. But Sesame has now teamed up with Israel-based Watergen, which makes atmospheric water generators that pull H2O from humidity in the air, purifies it for drinking and has its U.S. headquarters in North Carolina.
By combining their technologies, they’ve come up with a system that ensures a steady supply of deionized water for green hydrogen production, advancing Sesame Solar’s off-grid system, says Lauren Flanagan,“Being able to now make our own water as needed, to make our hydrogen gas as needed, to in turn be the backup power to the battery if solar conditions are not ideal, it’s unique. Nobody’s really applied it this way that we’re aware of,” Flanagan says.
