Biomass-derived hydrogen for the circular energy economy. Agricultural waste becomes a traceable, application-classified hydrogen resource — purified, measured and verified batch by batch.
SPX-BIO-HYDROGEN™ is produced from biomass-derived gas streams using gas cleaning, water-gas-shift conversion, hydrogen-selective separation and final purification. If the process starts with pyrolysis rather than gasification, the resulting hydrocarbons generally require additional reforming/conditioning before the gas is hydrogen-rich enough for this pathway.
Measure. Purify. Verify. Trace.
Stage 2 produces a gas stream of H₂ + CO + CO₂ + CH₄ + H₂O + other components, with exact composition depending on feedstock, moisture, reactor technology and operating conditions. Stage 3 removes tar, particulates, sulphur compounds, ammonia, alkali compounds and other contaminants. Stage 4 applies the water-gas-shift reaction (CO + H₂O → CO₂ + H₂) to increase hydrogen yield. Stage 5 separates hydrogen using hydrogen-selective membranes and/or Pressure Swing Adsorption (PSA).
These numbers are SPX product classifications, not claims of compliance with a particular hydrogen standard. For fuel-cell or transport applications, the product must meet the applicable hydrogen-fuel specification — ISO 14687:2025 specifies hydrogen fuel quality for residential, commercial, industrial, vehicular and stationary applications.
Rather than implying “100 = 100% hydrogen,” SPX-BIO-H₂ 100 is defined as the highest SPX application class, subject to verified hydrogen purity and contaminant limits. The certificate shows the actual measured H₂ concentration (for example, H₂: XX.XX mol%) alongside individual impurity measurements — never a rounded or implied claim.
The customer can scan a QR code and see the verified production and quality information for that batch.
An industrial facility requires hydrogen for a process. Agricultural biomass → thermal conversion → syngas → gas cleaning → WGS → H₂ separation → SPX-BIO-H₂ → industrial process. Potential applications include industrial processing, heat treatment, hydrogenation, chemical processing and metallurgical processes — actual suitability depends on hydrogen quality and equipment requirements.
Example grade: SPX-BIO-H₂ 30–60
Higher-purity SPX-BIO-H₂ grades could be developed for fuel-cell applications: biomass → syngas → CO conversion → H₂ separation → high-purity hydrogen → fuel cell → electricity + heat + water. ISO 14687:2025 defines hydrogen quality requirements for PEM fuel-cell applications specifically, so SPX-BIO-H₂ 90/100 is positioned as a fuel-cell qualification pathway, not a claim of automatic compliance.
Example grade: SPX-BIO-H₂ 90 / 100
A future pathway: biomass → SPX hydrogen production → high-purity H₂ → compression → hydrogen station → fuel-cell vehicle. This requires compliance with the relevant hydrogen fuel-quality, compression, storage and fuelling requirements, so SPX-BIO-H₂ 100 is positioned as a mobility-grade development target, subject to certification and testing.
Example grade: SPX-BIO-H₂ 100 (R&D pathway)
Hydrogen can also be used as an industrial energy carrier: SPX-BIO-H₂ → industrial burner/heating system → high-temperature process heat. Potential sectors include steel, glass, ceramics, chemicals, food processing and industrial manufacturing — required hydrogen quality and combustion-system design depend on the application.
Example grade: SPX-BIO-H₂ 50–80
The NZLoop model can produce both electricity (syngas → engine/turbine → electricity) and hydrogen (syngas → WGS → separation → SPX-BIO-H₂) from the same biomass stream, alongside Bio-Oil, Bio-Tar and Biochar — a flexible, multi-product biorefinery model.
Example grade: Multi-product output
The water-gas-shift stage converts CO + H₂O → CO₂ + H₂. The resulting CO₂-rich stream can potentially be separated and managed separately — biomass → syngas → H₂ production → CO₂ separation → hydrogen product + CO₂ stream — creating opportunities for integrated carbon management, subject to a full mass balance and lifecycle assessment.
Example grade: Integrated with carbon workflows
This creates a much stronger product proposition than simply selling “green hydrogen.”

SPX-BIO-HYDROGEN™ is Soil Passport's biomass-derived hydrogen product platform — biomass gasification produces a hydrogen-rich syngas, which is then reformed and purified into classified hydrogen grades.
Through gasification of biomass-derived syngas, followed by water-gas-shift conversion, hydrogen separation and purification.
Primary applications are clean hydrogen for industry and transport decarbonisation, as a renewable alternative to grey hydrogen. Refining and fuels applications are treated as potential, pending qualification for the specific process.
SPX-BIO-HYDROGEN™ is graded by purity and application classification, backed by a digital Hydrogen Quality Passport documenting feedstock, process and purification data.
The same thermal conversion platform can also yield SPX-BIO-OIL™, SPX-BIO-TAR™ and SPX BioChar™ depending on process configuration and feedstock.
It's biomass-derived hydrogen, which is a renewable pathway distinct from electrolysis-based green hydrogen — suitability for a specific green-hydrogen standard depends on the methodology and feedstock involved.
