How it works

CH₄ → 2H₂ + C. No combustion, so no direct CO₂.

The plasma arc splits methane directly into hydrogen and solid carbon. Unlike steam reforming, nothing is burned or oxidised.

Guide: what is methane pyrolysis? →

1

(Bio)methane in — natural gas, biogas or flare gas, 1–6 barg.

2

Three-phase plasma arc — above 3,000°C; the arc’s motion mixes the gas, no oxygen involved.

3

Hydrogen and solid carbon out — two valuable products, zero direct CO₂.

Inside the unit

From gas skid to carbon filter.

The whole process in one containerised unit: power and control, gas feed, the plasma reactor and the carbon separation.

Inside the HyPlasma unit: control cabinets, gas skid, plasma torch and carbon filter

Control cabinets

Power supply and control of the plasma torch.

Gas skid

Meters the methane, and the inert gas used for start-up and cleaning.

Plasma torch

The three-phase torch on top of the reactor, where methane splits into hydrogen and carbon.

Carbon filter

Separates the solid carbon from the hydrogen; a screw conveyor carries it out.

Technical features

The most cost-effective route to clean hydrogen.

Solid carbon powder and a hydrogen molecule: the two products of HyPlasma

Combined valuable products

Clean hydrogen and high-value solid carbon in a single process, without direct CO₂. Conventional routes rely on separate, energy-intensive processes for hydrogen production and carbon handling.

Competitive cost

Low, stable production costs compared with conventional low-carbon hydrogen. Methane pyrolysis needs far less electrical energy per kilogram of hydrogen than water electrolysis, and the solid carbon co-product adds a revenue stream. Limited maintenance, economical consumables and no AC/DC rectifier keep the architecture simple.

No carbon bill

SMR pays around €0.70/kg H₂ in CO₂ costs at today’s EU ETS price. HyPlasma® emits no direct CO₂, so there’s nothing to pay, and that gap grows as the carbon price rises.


Indirect emissions depend on your electricity mix and gas source.

Low footprint

An optimised, pressurised design: operating at up to 6 barg reduces internal gas volumes and downstream equipment size, so the plant fits existing industrial sites where space is critical.

Competitive cost

What a kilogram of hydrogen costs in Europe.

In 2026, HyPlasma is slightly cheaper than steam methane reforming once SMR’s carbon cost is counted, and 2.4 times cheaper than electrolysis. Select a year to see the values.
