Gas Mixing Systems for smooth Transitioning to Hydrogen

Industrial use of green hydrogen (H2) as an energy source for process heat is gaining importance as companies seek sustainable alternatives to fossil fuels. Gas mixing systems offer a flexible solution for blending H2 with natural gas or for generating synthetic natural gas (SNG). This allows for a gradual transition to hydrogen-based energy.

 

Most existing installations and thermal process plants can handle gas mixtures with up to 20% H2 content, sometimes even up to 30%. An integration of a gas mixing system provides several benefits:

·        Increased flexibility

·        Enhanced supply security

·        Cost optimization opportunities without changing plant technology

 

Gas mixing systems enable companies to switch between different energy sources like H2, natural gas, and as well propane or CO2, adapting to market conditions and meeting both economic and ecological goals. However, transitioning to H2 presents challenges:

·        Impacts on gas supply networks, process plants, and burner limits

·        Changes in combustion characteristics and flame properties

·        Safety considerations and explosion risks

·        Regulatory and certification requirements

 

To address these issues, gas mixing systems allow for testing different H2 concentration scenarios by blending various gases and to evaluate effects on equipment and processes. Applications range from large consumers in steel, glass, and ceramics industries to burner institutes, industrial furnaces, and engine/turbine development. Gas mixture flow rates typically range from 10 to 10,000 Nm³/h, and up to 100 MWh/h.
