South Africa · EU export

Export-ready RFNBO compliance for South Africa's green hydrogen projects.

Hydromize combines modular software and expert support to turn EU RFNBO requirements into a clear, auditable workflow — from project design to Proof-of-Sustainability.

Built on European RFNBO certification experience — now tailored for South Africa's export pipeline.

The evidence chain that connects renewable power to a certifiable Proof-of-Sustainability.

Why this matters now

South Africa is scaling. Europe is verifying.

South Africa's hydrogen economy is moving from strategy documents to real projects — with a strong pipeline aimed at industrial decarbonisation and premium export markets.

Those European offtakers, financiers and regulators demand credible RFNBO verification. The rules exist. The verification infrastructure, particularly on the producer side, is still catching up.

Without a robust evidence chain, projects face delays, costly rework and audit risk — right when speed to market matters most.

  • Design RFNBO compliance in early — avoid costly redesigns later.
  • Keep evidence traceable across the entire value chain.
  • Stay audit-ready as rules and buyer expectations evolve.
The problems we remove

Compliance friction, engineered out.

RFNBO complexity in project design

Additionality and temporal correlation shape decisions long before FID — but they're often left too late.

Fragmented data and documentation

Renewable inputs, production logs and GHG numbers live in disconnected tools that don't reconcile.

Audit risk and last-minute surprises

Missing evidence surfaces late in the audit — stalling shipments and offtake contracts.

Manual PoS workflows that don't scale

Spreadsheet-driven Proof-of-Sustainability breaks the moment volumes or scope grow.

No single source of truth for sustainability evidence

Every stakeholder rebuilds the same story from scratch — with a different version each time.

What is Hydromize?

Hydromize = Software + experts. One workflow.

Digital Twin

Model your plant and value chain with the parameters that certification actually depends on.

GHG & lifecycle calculation

Run scenarios, validate the ≥70% saving threshold, and keep numbers reproducible.

PoS-ready documentation

Structured workflow and operating model support that produces audit-clean evidence packages.

Before, during & after certification

Expert support across pre-feasibility, active certification, and continuous operations.

Compliance should be a catalyst — not a bottleneck.

How it works

Three steps from design to audit-ready.

01

Pre-check & project setup

Lock in certification-critical design choices early — PPA structure, additionality, metering architecture and commissioning windows.

02

Evidence & calculations

Track renewable inputs, correlation logic, and GHG accounting in a structured system with a full audit trail.

03

Audit-ready output & ongoing operations

Produce clean audit packages and run continuous PoS processes as production and offtake scale.

Use cases · South Africa

Built for the projects moving the SA hydrogen economy.

IPPs & developers exporting to Europe

Typical challenge

Hydrogen and derivatives (ammonia, SAF, e-fuels) must clear RFNBO before EU offtake contracts close.

How Hydromize helps

Design the compliance envelope during FEED and produce PoS packages that match buyer and auditor expectations.

Industrial offtakers replacing grey hydrogen

Typical challenge

Sustainability claims need defensible provenance across the value chain.

How Hydromize helps

Traceable evidence from renewable input to on-site consumption, with GHG numbers ready for reporting.

Utilities exploring hydrogen for flexibility & storage

Typical challenge

Multiple electricity sources and operating modes complicate correlation logic.

How Hydromize helps

A Digital Twin that keeps additionality and temporal rules straight across scenarios.

Logistics & ports needing verifiable green fuel claims

Typical challenge

Downstream buyers demand fuel-specific proof, not portfolio averages.

How Hydromize helps

Batch-level PoS output aligned to shipment and delivery documentation.

Differentiation

Why Hydromize by GreenTrax.

Bridge between Europe and South Africa

EU RFNBO know-how paired with a focus on the SA export pipeline.

End-to-end sustainability documentation

A mindset — not just a tool. We handle the workflow, not just the form.

Practical audit preparation

Operational readiness so audits are validation, not discovery.

Clear, modular approach

Start small, scale up. Adopt what you need, when you need it.

FAQ

Frequently asked questions.

RFNBO stands for Renewable Fuels of Non-Biological Origin. Under EU regulations, hydrogen and derivatives (like ammonia, e-methanol or SAF) must meet specific RFNBO criteria — including additionality, temporal and geographical correlation, and a lifecycle GHG saving of at least 70% — to count toward European renewable energy targets.
