Green Hydrogen – Unlocking value from hydrogen-rich process gases

Hydrogen is increasingly viewed as a key component of future energy and industrial systems.

Demand is growing across sectors such as:

  • heavy industry

  • chemicals and refining

  • energy storage

  • mobility and transport

At present, however:

Most global hydrogen production still relies on fossil fuels.

The role of pyrolysis gases:

During pyrolysis, hydrogen-rich synthesis gases are generated as part of the thermochemical conversion process.

These gases typically contain:

  • hydrogen (H₂)

  • carbon monoxide (CO)

  • methane and light hydrocarbons

In many systems, these gases are primarily used internally to sustain process energy demand.

However, depending on:

  • feedstock composition

  • reactor configuration

  • heat integration efficiency

a portion of the gas stream may also be recovered, upgraded, and purified for additional applications.

From syngas to usable hydrogen.

To obtain industrially usable hydrogen, gas streams typically require:

  • gas cleaning

  • tar and particulate removal

  • gas separation technologies (e.g. PSA or membrane systems)

  • optional water-gas-shift upgrading

This enables the production of:

Low-carbon hydrogen from waste-derived process streams.

Strategic advantage

Unlike standalone hydrogen production systems, pyrolysis-based systems:

  • generate hydrogen-rich gases as part of an existing process

  • simultaneously produce additional outputs (biochar, heat, oils)

  • stabilize carbon in solid form instead of fully releasing it as CO₂

This creates:

Multi-output systems with integrated carbon management.

Potential applications

Recovered hydrogen streams may support:

  • industrial heat and processing

  • local energy systems

  • hydrogen blending applications

  • fuel and mobility sectors (depending on purity and infrastructure)

Economic and system relevance

The economic viability of hydrogen systems often depends on:

  • infrastructure costs

  • electricity prices

  • utilization rates

Pyrolysis-based pathways may offer advantages in situations where:

  • waste streams are already available

  • process heat is internally integrated

  • multi-output economics improve overall efficiency

The Satoumi perspective

Satoumi systems are not positioned as dedicated hydrogen plants.

Instead, they enable:

The recovery of additional value from process gases already generated during waste conversion.

This approach aligns with broader trends toward:

  • decentralized energy systems

  • circular carbon utilization

  • integrated industrial processes

In this context, hydrogen is not treated as an isolated product —

it becomes part of a broader system that combines waste conversion, energy recovery, and carbon stabilization.

Interested in becoming an early partner?

Satoumi is currently seeking pilot partners to realize the first projects and move the technology into real-world deployment.

At this stage, we are primarily looking for organizations capable of participating in early implementation, prototyping, manufacturing, or operational pilot projects.

If your organization is interested — even if the timing is not yet ideal — we encourage you to contact us.

We are happy to:

  • provide additional technical information

  • discuss potential collaboration models

  • evaluate whether a partnership is a good fit

  • place interested organizations on our early partner and deployment waitlist

We are also working toward making complete reactor systems available in the future through manufacturing and deployment partners.

If you are interested in:

  • future reactor purchases

  • licensing opportunities

  • pilot deployments

  • or future rental/leasing models

we would be glad to stay in contact and reach out once the appropriate deployment stage is reached.
