Software allows renewable gases to be fed into gas grids

SmartSim software

Variations in gas properties have been steadily increasing for some years. These variations are driven by the diversification of natural gas supplies and the growing number of biogas plants feeding into natural gas grids. In future these grids will also have to accommodate increasing quantities of hydrogen produced by power-to-gas plants using excess energy. These developments represent a great challenge for network operators who need to bill their customers with an accurately determined calorific value for the gas delivered.

The SmartSim method developed by E.ON allows gas flows in the pipeline network to be simulated so that the superior calorific value can be precisely determined at all exit points. It provides gas suppliers in service areas with several natural gas or biogas feed-in points with a tool for correctly billing their customers. The main advantage of this gas quality tracking tool is that in areas where bio natural gas is fed into the system, the superior calorific value no longer needs to be adjusted by adding propane (as is current practice). As a result, network operators save costs and avoid additional CO2 emissions.

Benefits of gas quality tracking for grid operators

SmartSim Gas Software
  • Correct customer billing even where gas qualities vary.
  • Ability of the grid to accommodate different gases (natural gases, bio natural gas, hydrogen).
  • Helps avoid costly alternatives (expensive instrumentation or gas conditioning to achieve the desired calorific value).
  • Provides detailed knowledge of the gas quality distribution across the entire grid both in terms of time and location.
  • Customer support for questions related to specific gas characteristics (Wobbe index, methane number etc.).
