In this episode of Earthlings 2.0, we talk with Gary Ong, CEO of Celadyne Technologies, a company focused on making hydrogen a more accessible energy source through its membrane technology. We explore why hydrogen adoption has lagged, how issues such as hydrogen crossover and membrane degradation hold back today’s fuel cells and electrolyzers, and how Celadyne’s low-permeability membrane addresses these problems and significantly improves durability. Gary explains how the technology functions as a true drop-in solution, why Celadyne is focusing on supplying membranes to partners like General Motors and the U.S. Army, and how he expects hydrogen to scale across heavy transportation and energy systems by 2035.

Key Points:

• Hydrogen for heavy transport and industry – Hydrogen is emerging as a strong option for decarbonizing heavy-duty sectors—trucks, logistics, shipping, rail, aviation, and other long-life industrial applications—where today’s energy solutions, including diesel and natural gas, face limitations in meeting long-range, continuous-operation demands.
• Why membranes matter so much – Proton exchange membranes must block gases, conduct protons, and block electrons; today’s mostly Teflon-based membranes let too much hydrogen cross over, causing unwanted side reactions like hydrogen peroxide formation that drive degradation and limit durability and efficiency.
• Celadyne’s low-permeability membrane – By more effectively blocking hydrogen while still conducting protons, Celadyne’s membrane reduces crossover and side reactions, which Gary says can quintuple durability in applications like fuel cell trucks, bringing lifetimes closer to 15–20 years.
