Ready for the future networks being built today

The gas industry is undergoing its most significant infrastructure change in a generation. Existing networks are being repurposed for hydrogen and CO₂ transport. New distribution networks must handle blended gases, hydrogen, biomethane and natural gas simultaneously, while billing customers fairly for energy that varies in calorific value from node to node.

Discover three technical papers below that demonstrate how we've deployed Atmos Simulation (SIM) Suite to overcome the challenges pipeline operators are facing as they respond to the energy transition.

Hydrogen and biomethane blending

Blending hydrogen and biomethane into existing networks creates two simultaneous challenges:

  1. Managing the hydraulic impact of variable-density
    gas
  2. Billing customers fairly when calorific value
    varies across the network.

Atmos SIM’s real-time digital twin addresses both in a single platform.

Pure hydrogen pipeline simulation

Repurposing existing infrastructure for hydrogen transport requires rigorous pre-commissioning analysis. Atmos SIM has been validated on pure hydrogen and blended pipelines.

CO2 transport & carbon capture CO2

CO2 pipelines operate under conditions conventional gas simulation tools were not designed to handle. Atmos SIM models dense phase behaviour, impurity sensitivity, and pressure transients accurately, giving operators the
confidence to commission.
