The Algae Fuel Reality Check: What Didn’t Add Up

What happens when a bold “green” idea meets real-world economics? In this episode, I take a closer look at ExxonMobil’s long-running algae biofuel effort—a project that promised a cleaner, scalable alternative to traditional fuels.

But behind the headlines, the numbers tell a different story. From production yields and land use to water demands and overall costs, this is a case study in how quickly optimism can unravel when measured against operational reality.

This episode breaks down where the challenges emerged, why scaling proved so difficult, and what it reveals about the broader gap between “green” narratives and what actually works when the math has to pencil out.
