Will your plant deliver the tonnes you contracted in a poor weather year?
We model your plant against real weather and power prices and work out how to design and run it to deliver what you contracted. Our e-SAF design model reproduces the San Roque results from the RH2EDIN 2026 work. Each recommendation comes with its assumptions and a feasibility check.
The decisions
The decisions that set what a power-to-X plant earns
Dispatch
When to run the electrolyser against power prices and renewable output, inside the RFNBO matching rules.
Buffers and storage
How much hydrogen, CO2 and power buffer keeps the plant running when renewable supply dips under hourly matching.
Design under uncertainty
Which plant delivers the contracted tonnes in a poor weather year, with P50 and P90 cost and delivery across many weather years, before the final investment decision.
Ramp-up and feedstock
How hydrogen and CO2 supply, synthesis turndown and start-up interact while the plant reaches rated output.
Contracts
How PPAs and offtake commitments change what the plant should do hour by hour, and what a missed tonne costs.
Compliance records
Which hours count as renewable, recorded as the plant runs for the certification auditor.
What exists today
What we have built
A design model for e-SAF
Our e-SAF plant design model from the RH2EDIN 2026 work. It reproduces that work’s San Roque results within tolerance.
Certified optimisation
Each linear-programme result comes with an exact certificate that it is optimal, checked by separate code that does not share the model.
A reference hydrogen hub
A synthetic hydrogen hub, modelled asset by asset, where we test ways of running a plant.
Ports
Hydrogen at the port
We built these models for the RH2EDIN 2026 port challenge.
Refuelling stations
Where, when and how big to build hydrogen refuelling while nobody knows how fast trucks and ships will switch.
Supply runs
How to route tube trailers so every station stays supplied without trucks running half empty.
Leaks
Where to put gas sensors, and how to spot a slow leak in the mass balance long before an alarm would.
How it starts
A benchmark on your own numbers
The first engagement is a fixed-scope optimisation benchmark on your design basis or plant data. It compares our best plan, with its optimality certificate, against the plan you would otherwise follow. Scope and price are agreed in writing first.
The boundary
It advises, and your control system decides
What we build does not write to a PLC, a DCS or a safety instrumented system. Its read-only connection runs through a site gateway that follows ISA/IEC 62443 zoning, and operators can overrule every recommendation. See security and data.
FAQ
Questions about e-fuels plants
Which rules does it follow?
The RFNBO delegated acts, year by year, including hourly matching from 2030. The rules are kept as dated versions, so the model follows them as they change.
Can we see it?
Yes, in a working session with your own questions.
Start with one plant
Tell us which plant, and which decision
A design under study, a plant in commissioning or one already running. A partner will tell you what a benchmark would cover and cost.
