Is GasIQ free to use?

Yes. GasIQ runs in your browser and is free to use. No account or install is required for the public workbench.

What units does GasIQ support?

Flow in Nm³, Sm³, scf, MSCFD, MMSCFD and actual/reference m³; energy in MWh, GJ and MMBtu; price basis in €/MWh, $/MMBtu and more.

Is GasIQ accurate enough for custody transfer?

No. GasIQ is an engineering and commercial screening tool. For fiscal metering use a calibrated AGA-3 or ISO-5167 flow computer.

Can I save and export my work?

Yes. You can save cases locally, export JSON and CSV, and generate a print-ready PDF report.

GasIQ

Free · Engineering-grade · No install

Your gas did not change.
Your basis did.

Enter one natural-gas basis. GasIQ turns it into flow, gas quality, emissions, price-basis, hydrogen blending, steam reforming estimates and client-ready reports — with assumptions visible.

What it does

Define the gas once. Add only the answers you need.

Each result is a self-contained card with its own assumptions, so a quick property check and a full commercial valuation live side by side — nothing you don't ask for.

How it works

Define the gas

Enter a flow value, pick a unit, and choose a composition preset or paste your chromatograph.

Build your results

Add commercial, emissions, combustion or flow cards. Each shows its calculation assumptions inline.

Export & share

Save the case, export JSON or CSV, or generate a print-ready PDF report for the file.

Who it's for

One tool, two desks.

Process & facilities engineers

Check Wobbe and calorific value, size combustion air, screen hydrogen blends, and convert between Nm³, scf and MMSCFD without a spreadsheet.

→Combustion & flue-gas estimates
→Reference-condition & Z-factor control
→Hydrogen blend screening

Commercial & trading teams

Move a volume to an energy and a price basis in seconds — €/MWh, $/MMBtu — with fuel and carbon cost, then issue a clean report.

→Price-basis & FX conversion
→Carbon cost of combustion
→Client summary and internal validation report modes
