A Wake-Up Call for Resilience

The recent catastrophic flooding in Texas that took the lives of over a hundred people is a sobering reminder of the escalating risks posed by extreme weather events. Our hearts go out to the victims, their families, and the affected communities who are facing unimaginable loss and disruption.

While no technology can undo the human toll of disasters, it is crucial to ask: what can we do to prevent future tragedies or minimize their impact?

One of the answers lies in adaptation — the urgent need for resilient infrastructure and innovative off-grid energy technologies that can operate during and after disasters. Sesame Solar’s Mobile Nanogrids offer a compelling, proven solution to help communities stay connected, powered, and safe during floods and other extreme weather events.

Why Floods Demand Climate Adaptation Now

Flooding is the most common and deadly natural disaster in the United States. According to FEMA, just one inch of water can cause over $25,000 in damage to a home or business. In Texas, many communities are particularly vulnerable due to aging infrastructure, inadequate drainage systems, and increasing rainfall intensity driven by climate change.

The Texas flood was not an isolated event; it is part of a growing trend. NOAA reports that the number of billion-dollar flood disasters has doubled over the past two decades. In the face of these challenges, adapting to climate reality is no longer optional.

Resilient energy access is a critical component of that adaptation.

What Are Sesame Solar’s Mobile Nanogrids?

Sesame Solar’s Mobile Nanogrids are rapidly deployable, self-sustaining energy hubs that generate power using solar, green hydrogen and battery storage—no fuel required. Housed in towable units (the size of a trailer or shipping container), these Nanogrids are designed for fast setup (<15 minutes), requiring no specialized training and minimal infrastructure.

Once deployed, they can:

• Generate reliable and resilient off-grid energy
• Store power in onboard batteries
• Power-critical services like medical equipment, Wi-Fi and lights
• Run emergency communications and charging stations
• Be relocated as needed to disaster zones
  
  

These units don’t rely on fossil fuels, so they remain operable even when fuel supplies are disrupted — a common occurrence during floods.

How Sesame Solar Nanogrids Help During Floods

1. Providing Emergency Power When the Grid Fails

Flooding often causes power outages by damaging electrical substations, downing lines, and shorting out infrastructure. These outages can last days or even weeks.

Sesame Solar Nanogrids ensure continuous power delivery during these blackouts. First responders, shelters, mobile clinics, and emergency communication teams can operate independently of the grid, improving survival outcomes.

In the case of Texas, where homes and hospitals were plunged into darkness, Mobile Nanogrids could have delivered instant, clean energy to meet urgent needs.

2. Supporting Mobile Medical Units and Clinics

During floods, access to healthcare becomes critical. Contaminated water, injuries, infections, and chronic health conditions can quickly become life-threatening.

Sesame Solar’s Nanogrids have powered mobile medical units in the Caribbean and remote U.S. regions. With integrated HVAC, lighting, clean water access, and power for refrigeration and medical tools, they can serve as mobile clinics to reach flood-impacted neighborhoods.

This can be especially important in underserved or rural areas, where existing healthcare facilities are sparse or inaccessible due to water damage or road closures.

3. Keeping Communities Connected

Communication is a lifeline during disasters. But cell towers, routers, and base stations often go offline during floods due to power failure.

Equipped with Internet and voice connectivity through 5G and satellite, Nanogrids from Sesame Solar can support critical first responder communications and coordination, operating as a mobile command center moving to various locations to facilitate disaster response efforts. Nanogrids also support local telecom networks and Wi-Fi hotspots, enabling families to contact emergency services or check in with loved ones. Local officials are also able to broadcast public safety messages and coordinate response efforts, ensuring information flows smoothly even in chaotic situations.

4. Safe and Rapid Deployment

Floods move fast. Response solutions need to be even faster. Sesame Solar’s Mobile Nanogrids can be set up in under an hour, require no wiring or trenching, and can be pre-positioned or deployed rapidly.

Unlike diesel generators, which can take days to arrive and require a constant supply of fuel, these solar-powered systems are immediately functional with minimal human intervention.

5. Long-Term Adaptation and Community Resilience

Sesame Solar’s solutions aren’t just for the immediate aftermath. Communities can use Mobile Nanogrids as part of a long-term resilience plan.

For example:

• Schools can use them as resilient learning hubs.
• Municipal governments can station them in flood-prone zones year-round.
• Local clinics can expand into rural areas where electricity remains unreliable.
  
  

This flexibility makes them ideal tools for building extreme weather-adaptive infrastructure, not just responding to disasters.

Additional Features That Boost Flood Response

• Battery Storage: Stores energy for use at night or during cloudy conditions.
• Built-in Water Filtration (Optional): Adds another layer of public health support during waterborne disease outbreaks.
• Modular Design: Can scale depending on need, from small charging stations to full-scale relief hubs.
• Green Hydrogen Integration: When extended sunlight isn’t available, hydrogen fuel cells can take over to ensure uninterrupted clean energy.
  
  

Not Just For Governments — For the People

Sesame Solar works with local governments, tribal nations, public health agencies, and NGOs. But these Nanogrids can also serve community-based organizations and mutual aid groups that play a critical role in disaster response.

In communities like those devastated by the Texas floods, community centers, churches, and food distribution sites could all benefit from reliable off-grid power to support neighbors.

Real-World Readiness

Sesame Solar has already proven its capabilities in:
