Natural Disasters Are Happening 3x More Often Than 50 Years Ago. This Company Built a Better Response.

Natural disasters are not getting rarer. They are getting more frequent, more severe, and more damaging to the infrastructure communities depend on in a crisis.

The data is stark: natural disasters are occurring three times more often than they did 50 years ago. Wildfires, hurricanes, floods, and ice storms are disrupting communities at a scale that the conventional emergency response system was never designed to handle.

And here is the uncomfortable irony that Lauren Flanagan, CEO of Sesame Solar, brought to the Driving Mobility podcast: the traditional tools we use to respond to these disasters are part of the same problem that causes them.

The Problem with Conventional Disaster Response

When a hurricane or wildfire knocks out power to a community, the standard response involves deploying diesel generators. Diesel generators are loud, they produce emissions, and they depend on a fuel supply chain that is often disrupted by exactly the same events that created the need for backup power in the first place.

In the aftermath of a major hurricane, getting diesel fuel to the places that need it is a logistical challenge. Roads may be impassable. Supply chains are disrupted. The communities most in need of power often get it last.

Beyond the logistics, there is the environmental dimension. The climate change that is driving more frequent and severe disasters is itself partly a product of fossil fuel combustion. Using diesel generators as the primary disaster response tool means burning more fossil fuels in the aftermath of events that fossil fuel emissions helped cause. It is a cycle that Flanagan is working to break.

What Sesame Solar Built

Sesame Solar's nanogrids are mobile, fully renewable energy systems that run on solar power and green hydrogen to provide reliable power wherever they are deployed. They produce no emissions. They do not depend on a diesel supply chain. They can be transported to disaster zones and operational quickly.

The green hydrogen component is particularly significant. Solar power is intermittent: it generates electricity when the sun is shining and nothing when it isn't. Green hydrogen provides energy storage that bridges that gap, allowing a solar-powered system to deliver consistent power through the night and during cloudy conditions.

This combination, mobile solar generation paired with green hydrogen storage, produces a disaster response power system that is genuinely independent of the grid and the fossil fuel supply chain. It can operate wherever it's needed, for as long as it's needed, without refueling runs and without emissions.

Why This Matters for Mobility

The connection to mobility is direct. Transportation infrastructure is among the first things affected in a major disaster. Roads, traffic systems, electric vehicle charging infrastructure, and the facilities that support fleet operations all go down when the grid fails.

A mobile, renewable power source that can be rapidly deployed changes what is possible in a disaster response context. EV fleets used in emergency response can be charged without a functioning grid. Temporary facilities supporting disaster relief operations can be powered without diesel generators. Communities can maintain basic transportation functionality during extended outages.

As fleet electrification advances, the dependency on grid power for transportation operations increases. That makes resilient, off-grid power sources more important, not less, for fleet operators planning their long-term infrastructure.

The Business Case for Clean Disaster Response

Flanagan's work at Sesame Solar is grounded in a conviction that environmental responsibility and commercial viability are not competing goals. The nanogrid technology she's developing is not a charity project. It is a product designed to do a job better than the alternative.

The total cost of deploying a diesel generator-dependent disaster response, including fuel, logistics, maintenance, and the environmental costs that are increasingly being factored into organizational decision-making, compares less favorably to clean alternatives than it once did.

For governments, NGOs, and large organizations that are setting public commitments to decarbonization while also having operational responsibilities in disaster-prone regions, Sesame Solar's approach represents a way to meet both sets of obligations simultaneously.

The Climate Feedback Loop

Flanagan's perspective on why this work is urgent rests on a clear-eyed view of the feedback loop at play. Climate change causes more disasters. Disasters are responded to with fossil fuel combustion. That combustion contributes to climate change. Breaking that loop requires deploying clean energy specifically in the disaster response context, not just in the baseline energy mix.

That framing gives the work a particular urgency. It is not just about being more sustainable in normal operations. It is about not making the underlying problem worse in the moments when communities are most vulnerable.
