Decarbonizing HEFA’s process heat, whether by grid electricity or carbon capture, could save a HEFA plant up to 29 cents per gallon with Washington state’s current incentive structure.

Sustainable Aviation Fuel (SAF) is gaining momentum as a key tool in decarbonizing the aviation sector—but not all SAF is created equal. In this insight, we compare three of the most widely used U.S.-approved SAF technologies: Fischer-Tropsch (FT), Hydroprocessed Esters and Fatty Acids (HEFA), and Alcohol-to-Jet (AtJ). Using Sesame Sustainability’s modeling platform, we evaluate their emissions profiles, production costs, and policy incentives. The results reveal how technology choice, feedstock, and carbon capture strategies can make or break SAF’s environmental and economic viability in today’s evolving policy landscape.

Heathrow’s power outage brought one of the world’s most advanced transportation hubs to a standstill. It was not the fire alone that caused the disruption—it was the absence of foresight in how the system was designed to respond.

At Sesame, we believe that infrastructure should not only work when everything goes right—it should hold up when something goes wrong. Because when you’re powering an airport, a city, or a planet, failure is never just local. It’s global.

Data-driven energy modeling optimizes power reliability, controls costs, and integrates renewables for maximum resilience. Our analysis examines how regional differences shape optimal strategies, comparing solar, battery, and hybrid solutions to prevent costly business disruptions.

In this insight article, we delve into the complexities of hydrogen-powered vehicles and their emissions beyond the tailpipe. While hydrogen fuel cells offer near-zero tailpipe emissions, the true environmental impact hinges on factors like vehicle design, mileage, and, crucially, the carbon intensity of hydrogen production.

In this insight article, we explore how different fuel cell sizes, combined with varying hydrogen prices, can significantly impact the economic feasibility of heavy-duty trucks. We will explore a case study that demonstrates the potential advantages of a smaller fuel cell, analyze why this problem remains open-ended, and consider the risks and other factors that fleet operators must consider when making these decisions.
