In this episode of The Hydrogen Podcast, we dive deep into the University of Texas Center for Electromechanics (UT-CEM) report: “Hydrogen, Air Quality, and Climate Change.”

🔹 The Problem: NOX, SOX, and PM2.5 emissions remain a major global public health risk—causing millions of premature deaths annually.
🔹 The Solutions:

• Fuel Cell Electric Vehicles (FCEVs): Zero tailpipe emissions, immediate health benefits in ports and urban corridors.
• Hydrogen Internal Combustion Engines (H2ICE): New breakthroughs show diesel-level performance with far lower NOX and PM2.5.
• Industrial Decarbonization: Hydrogen’s potential to replace high-emission fuels in refineries, steel, and chemicals.
  🔹 The Challenges: Infrastructure gaps, cost competitiveness, policy uncertainty, and ensuring hydrogen comes from low-emission sources.

We explore California’s ZEV mandate, Europe’s Stage V standards, and strategies for deploying hydrogen where it makes the biggest difference—urban fleets, ports, buses, and heavy-duty equipment.

💡 Key Insight: Every $1 spent on reducing NOX and PM2.5 yields a $30–$50 public health return. Hydrogen is more than a climate solution—it’s a public health tool.
