On May 16, 2024, a deadly trio of storms slammed into Houston, bringing hurricane-force winds, severe thunderstorms, and a tornado that claimed eight lives and left more than 1 million people without power. In the days that followed, residents endured 90+ degree heat without air conditioning or refrigeration, and tragically, at least one man died of carbon monoxide poisoning while operating a gas-powered generator in his home.

This catastrophic event is a stark reminder that we need more resilient and renewable alternatives—particularly for communities that face higher disaster exposure and have fewer resources for recovery. It’s time to rethink how we power emergency response and protect our most vulnerable neighborhoods.

Clean Mobile Power Solution as an Alternative to Fossil-Fuel Generators

Following power outages, most often residents and businesses will resort to power generators, which can be life saving; however, they can also be deadly. One death following the recent Houston storm included a man who died from carbon monoxide poisoning while running a generator after his power went out. In response, Fire Chief Samuel Pena called carbon monoxide a silent killer that follows storms, and he warned people to use power generators safely. Pena said the fire department has responded to 80 carbon monoxide incidents following this recent storm, including one incident in which four children were hospitalized by the gas given off by a generator. 

So, what are the safer alternatives to power generators? 

One solution is Sesame Solar’s Renewable Mobile Nanogrid. Fueled by solar + green hydrogen + battery storage, these Mobile Nanogrids bring power and essential services when and where needed, and are easily set up by 1 person in less than 15 minutes. They provide a continuous loop of reliable, renewable energy—like an energy-independent power plant—so there are no supply logistics or downtime like there are with fossil fuel. These Nanogrids operate in all weather conditions and have up to 150 square feet of interior space to be used for anything from a mobile medical hub to a communications hub, a cooling or warming center or a mobile office. Sesame's Mobile Nanogrids are fast to deploy, easy to use and flexible for dozens of use cases.  ‍

Climate Resilience for Economic Justice Communities

As of a week following the storms, thousands in Houston still remained without power, and according to Harris County Commissioner Lesely Briones, the deadly storms had a severe impact on many lower-income residents. 

One such neighborhood that is often vulnerable to weather disasters is Independence Heights. Located in Northern Houston, Independence Heights was the first city incorporated by a black community in the State of Texas. Today the community is home to around 14,000 residents of diverse backgrounds who have come together to continue working for economic justice within their region, especially following weather disasters. 50% of the community is in a flood zone, which is compounded by the improper construction of I-45 highway culvers, which flood during moderate precipitation, with more intense impacts during extreme weather. The community has been underserved with city, state and federal emergency response services after weather disasters, and are still recovering and rebuilding from the impacts of Hurricane Harvey in 2017.

So, what is the solution for these economic justice communities that are overburdened and underserved in the face of increasing weather and climate impacts? 

True to their mission, Independence Heights has taken steps to become more independent and resilient to disasters through emergency preparedness training. Sesame Solar has been working with Dr. Atyia Martin of The Black Resilience Network and Tanya Dubose of the Independence Heights Redevelopment Council to raise funds to establish a Sesame Solar Renewable Mobile Nanogrid as a Hub for Disaster Preparedness and Response in Independence Heights. 

The goal of this Mobile Nanogrid is to:

• speed emergency response in this underserved community using Sesame Solar’s Mobile Nanogrids,
• reduce operating costs by using fossil-fuel-free power, 
• help save the planet, and 
• create a sustainable economic model for community disaster response by generating good jobs, multiple streams of revenue including emergency deployment teams, Nanogrid rentals, EV charging income, and corporate sponsorships recognized on the Nanogrid’s billboard-sized walls. 

According to FEMA, as the frequency of natural disasters continues to increase, so does the disproportionate risk exposure for socially vulnerable communities. There is an urgent need for reliable, renewably-powered solutions to make a difference now. Sesame Solar hopes to work with other communities, like Independence Heights, to create a climate resilience plan that can be replicated for all disadvantaged communities. Over the last 5 years, the U.S. has spent $600 Billion dollars on weather disasters—and 560 weather disasters are expected to happen every year by 2030. The recent storms in Houston are a wake up call that we can no longer postpone investing in more renewable, off-grid power options for vulnerable communities.

Frequently Asked Questions

1. Why are fossil-fuel generators dangerous during and after storms?

Fossil-fuel generators emit carbon monoxide (CO)—a colorless, odorless gas that can be fatal when inhaled in enclosed or poorly ventilated spaces. After Houston’s recent storms, fire departments responded to dozens of CO poisoning cases, including incidents involving children and fatalities. These risks are magnified during outages when windows are closed, ventilation is limited, and people rely on generators for long stretches. In contrast, renewable nanogrids produce zero emissions, removing this health hazard entirely while providing consistent, off-grid electricity.

2. What makes Sesame Solar’s Nanogrids suitable for disaster response?

Sesame Solar’s Nanogrids are designed for rapid, reliable deployment in crisis scenarios. They’re mobile, self-sufficient, and powered by solar energy, battery storage, and green hydrogen. Each unit can be set up in minutes by a single person and used to power medical devices, communication hubs, water purification systems, HVAC, and refrigeration—critical services when infrastructure is damaged. Unlike diesel generators, Nanogrids don’t require fuel deliveries, operate quietly, and are safer to use near homes, shelters, or clinics. This flexibility makes them ideal for hurricanes, wildfires, floods, and even heatwaves.

3. How do Nanogrid hubs benefit historically underserved communities?

Communities like Independence Heights are often left out of the early recovery process due to limited resources and systemic neglect. A Nanogrid hub provides access to lifesaving power during outages, supports emergency coordination, and can house medical or cooling services in one compact, clean-energy unit. More importantly, these hubs can create local economic opportunity through workforce training, equipment rental, and sponsor engagement. This is not just about recovery—it’s about building climate resilience through community ownership and empowerment.

4. What makes the Independence Heights project a replicable model?

The Independence Heights Disaster Resilience Hub aims to serve as a template for other frontline neighborhoods nationwide. By combining clean energy with local partnerships, the model delivers not only emergency response capability but also economic uplift. It integrates community input, focuses on underserved populations, and establishes financial sustainability through rental income, EV charging, and brand partnerships. With over $600 billion spent on U.S. weather disasters in the last 5 years, this type of grassroots-powered, clean energy infrastructure can help reduce response costs while empowering those most at risk.

5. What steps can other cities take to adopt this solution?

Cities can start by identifying climate-vulnerable zones, especially those underserved by traditional emergency response systems. From there, municipalities can partner with clean energy providers, community organizations, and philanthropic networks to fund Nanogrid installations. Investing in local training for deployment and maintenance ensures job creation and operational self-sufficiency. Including Nanogrids in resilience planning, hazard mitigation strategies, and grant applications (like FEMA BRIC or Justice40 programs) can help accelerate adoption. With the right cross-sector coordination, cities can roll out this scalable solution across regions and at multiple preparedness levels.
