Neuman & Esser and Graforce have partnered to develop an integrated plant solution for low-carbon hydrogen production. The system uses plasma-pyrolysis to split methane from natural gas, biogas, or landfill gas into hydrogen and solid carbon, avoiding CO2 emissions during the reactor process. The technology claims methane conversion rates up to 98% with energy consumption between 10 and 15 kWh per kilogram of hydrogen. This turquoise hydrogen approach aims to provide a scalable industrial platform that aligns with EU low-carbon hydrogen regulations.

10 to 15 kWh per kg of H2 is the key number here. If they can actually hit that at scale without the equipment degrading from carbon buildup, it's interesting. What is the expected lifespan of the plasma torches before maintenance is needed?

The mention of the EU Delegated Act is the real driver. Without those specific low-carbon definitions, turquoise hydrogen struggles to compete with subsidized green H2. The success of this depends entirely on whether the solid carbon is treated as a product or a waste stream.

Using flare gas or landfill gas makes this a lot more practical for existing industrial sites. The big question is the solid carbon. If they don't have a buyer for the carbon black, they just traded a gas waste problem for a solid waste problem.

Exactly. The economics of the solid carbon are usually the make or break point for pyrolysis. If it's high purity, it's a win. If it's low grade, it's just landfill.
