In the latest epidose of The Clean Industry Podcast, and we went deep into a topic that gets oversimplified way too often: methane splitting.
At its core, the idea is simple. Split methane into hydrogen and solid carbon instead of burning it into CO₂. Where it gets interesting is how you do that, and what actually works at scale.
We talked through the main technology routes and their trade-offs. Plasma-based systems can prove scale but come with high electricity demand and mostly carbon black as the output. Molten metal and pure thermal approaches look elegant on paper but struggle with extreme temperatures, fouling, and mechanical complexity. Solid catalyst routes stand out because they operate at lower temperatures and give control over the carbon product.
That carbon detail matters. If the carbon forms with larger graphitic nuclei, downstream graphitization takes less time and energy compared to conventional synthetic graphite. That is a cost and CO₂ advantage that often gets missed when the focus is only on hydrogen.
On the hydrogen side, the appeal is practical. Many industries already sit on gas infrastructure. Decarbonization can start with modest hydrogen blends and scale up as equipment allows, without betting everything on new infrastructure from day one.
We also touched on policy. Technology-neutral regulation tends to speed things up. Picking winners too early tends to slow deployment and push projects to regions with clearer rules.
At the end of the day, customers care about emissions, speed, and cost. Methane splitting only works if it delivers on all three, with real uptime, bankable offtakes, and audited footprints.
If you are interested in what practical decarbonization actually looks like in heavy industry, this episode is worth a listen.
