The retractable solar array uses energy dense, thin-film solar panels that produce from 3 kW to 20kW of solar power, with total battery storage of 15 kWh to 150 kWh, although 40 kWh is most common. Electrolysis continues until the solid-state hydrogen storage tanks are refilled, and then it shuts off as well, making the nanogrid energy-independent and ready for the next extreme weather emergency with continuous,100% fossil fuel-free power generation. Then when the batteries have been recharged by the solar array, the hydrogen fuel cell shuts down. Electrolysis is engaged at the same time the hydrogen fuel cell powers up, so the solid-state hydrogen storage tanks are being refilled with hydrogen while hydrogen is being consumed by the fuel cell. When the batteries are at 35% capacity, the hydrogen fuel cell provides power to the inverter. The solar array charges the batteries whose power is managed by the inverter and electronics. The solar and green hydrogen work together with the help of a built-in integrated energy management system that ensures the resources are optimizing the available energy. “While we can’t stop hurricanes or wildfires from happening, we can create solutions that help communities recover efficiently without causing further damage to the environment.” “Our nanogrids are changing the trajectory of the effects of climate change while providing communities in distress with the power they need to access critical resources,” says Lauren Flanagan, CEO of Sesame Solar. When the batteries are charged, the H2 Fuel cell shuts down. The green hydrogen is then stored at low pressure (less than 300 psi) in onboard solid-state hydrogen tanks, which Sesame Solar says can be easily and safely transported, and which fuels the onboard hydrogen fuel cell that also charges the batteries. The green hydrogen is produced inside the nanogrid with the retractable solar array providing the energy to charge the lithium ferro phosphate battery storage system and to produce green hydrogen via electrolyzers. The Sesame solution uses solar and green hydrogen. Previous off-grid nanogrids were run on diesel fuel, which just increases pollution in communities already suffering from weather-related events. The systems can be tailored to the community’s need, for example in medical centers, for water filtration, or to provide communication services. To use the nanogrid, the retractable solar array is electronically unfolded, and the system can start generating power within fifteen minutes of setup, the company reports. They range from 10 to 40 feet long, and not only are they rugged, but they can be moved into place using a forklift, crane, truck, train, ship, cargo plane, or even a helicopter. 2019 grid parity white paperĪ new startup, Sesame Solar, unveiled its nanogrids that are designed for use in disaster torn areas.
