Low-Energy Methane Cracking for CO2-Free Hydrogen and High-Value Carbon Production

energyPilotedTRL 5

Imagine a way to split methane gas into hydrogen and solid carbon without burning it or using expensive chemicals. Instead of high heat, it uses a special kind of electric plasma—like a controlled lightning bolt—to break the molecules apart. This creates clean fuel and useful carbon soot without releasing any greenhouse gases into the air.

The business problem

What needed solving

EU hydrogen production relies heavily on fossil-based SMR, which creates high CO2 emissions and depends on volatile gas prices. Additionally, the EU lacks autonomy in producing critical carbon materials used in energy storage and manufacturing.

The solution

What was built

A fully integrated ColdSpark® reactor system including an optimized plasma chamber, a custom high voltage power supply (HVPS), and carbon handling subsystems.

Who can put this to work

Hydrogen Production
enterprise
Target: Industrial gas supplier

If you are an industrial gas supplier dealing with high CO2 emissions from traditional steam methane reforming—this project developed a plasma reactor that produces hydrogen with zero CO2 emissions and a process energy efficiency of 79%. This allows for a cleaner production path that cuts lifecycle emissions by over 60%.

Biogas & Waste-to-Energy
mid-size
Target: Biomethane plant operator

If you are a biomethane plant operator dealing with the need to valorize methane streams—this project developed a modular, catalyst-free system that converts biomethane into hydrogen and solid carbon. It operates at a low energy cost of less than 15 kWh/kg H2 produced.

Advanced Materials
SME
Target: Carbon nanomaterials manufacturer

If you are a materials manufacturer dealing with dependence on non-EU suppliers for critical carbon—this project developed a process to co-produce eCarbon® alongside hydrogen. This strengthens strategic autonomy by producing high-value solid carbon within the EU.

Frequently asked
