Green Hydrogen – Unlocking value from process gases
During pyrolysis, synthesis gases (syngas) are generated as part of the conversion process.
These gases typically contain:
hydrogen (H₂)
carbon monoxide (CO)
carbon dioxide (CO₂)
methane and light hydrocarbons
While often used internally for energy, these gas streams can also be upgraded into higher-value products.
From syngas to hydrogen
To obtain usable hydrogen, the gas stream undergoes several processing steps:
gas cleaning
→ removal of particulates, tar, and contaminants
water-gas shift reaction
→ converting CO + H₂O into additional H₂ + CO₂
gas separation technologies
→ such as pressure swing adsorption (PSA) or membrane separation
These steps enable the production of:
Purified hydrogen suitable for industrial use
Production characteristics (indicative)
Hydrogen yield depends strongly on feedstock and process configuration.
Typical ranges for biomass-based systems:
~20–60 kg of hydrogen per ton of feedstock (after upgrading)
Example (based on ~17 tons/day input):
~300–800 kg hydrogen per day
Actual values depend on:
reactor configuration
gas utilization strategy
upgrading system efficiency
Why this matters
Hydrogen is widely considered a key energy carrier for the future.
Global demand is growing rapidly due to:
decarbonization of industry
energy storage needs
fuel applications in mobility
integration into chemical processes
At present: The majority of hydrogen is still produced from fossil fuels
Unique advantage of pyrolysis-based systems
Compared to conventional hydrogen production:
hydrogen is generated as a byproduct of waste conversion
no dedicated large-scale electrolysis infrastructure required
carbon is stabilized in solid form (biochar), not emitted as CO₂
overall system efficiency benefits from multi-output production
combining carbon removal with hydrogen production
Potential applications
Hydrogen produced from pyrolysis can be used in:
industrial processes (e.g. steel, chemicals, refining)
energy storage systems
fuel applications (transport, heavy-duty mobility)
decentralized energy systems
System integration potential
In decentralized systems, hydrogen can be:
used on-site
injected into local energy systems
further processed or stored
This enables flexible deployment depending on local demand and infrastructure.
The Satoumi perspective
Satoumi systems enable:
decentralized generation of hydrogen-rich gas streams
flexible upgrading depending on application
integration into broader energy and material systems
Hydrogen is not necessarily the primary product —
but under the right conditions, it becomes a valuable additional output.
Strategic relevance
As hydrogen markets mature, systems that can:
produce hydrogen efficiently
combine it with other revenue streams
operate independently of large infrastructure
will gain increasing importance.
In this context, hydrogen is not the starting point of the system —
it emerges as a high-value output from an already productive process.
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.
