Aspen HYSYS Simulation of Green Hydrogen Blending with Natural Gas for Power Generation Gas Turbines

Hydrogen Blending in Gas Turbines: Performance Analysis & CO₂ Impact Building on our previous gas turbine modelling session, this video explores hydrogen blending from a thermodynamic perspective. We introduce up to 20% hydrogen into the fuel system while maintaining constant energy input to isolate the effects of hydrogen addition on turbine performance. What We Cover: • Setting up hydrogen combustion reactions in Aspen HYSYS • Creating a fuel blending station (mixer) for hydrogen + natural gas • Building a performance dashboard to track critical KPIs • Using adjust controllers to maintain target compositions and energy input • Analysing impacts on efficiency, power output, and emissions 📊 Key Results (20% H₂ Blending): ✓ Thermal Efficiency: 38.84% (vs 38.93% baseline) - minimal change ✓ Net Power Output: 22.8 MW (vs 22.89 MW baseline) - slight decrease ✓ CO₂ Emissions: 10,853 kg/hr (vs 11,677 kg/hr baseline) - 7% reduction ✓ Turbine Inlet Temperature: Stays within safe operating limits Critical Insight: 20% hydrogen blending yields only ~7% CO₂ reduction. This demonstrates that hydrogen is NOT a simple 1:1 replacement for natural gas, the relationship between hydrogen content and emissions reduction is non-linear due to thermodynamic properties. Who This Is For: • Process engineers working on decarbonisation projects • Energy professionals exploring hydrogen applications • Students learning gas turbine thermodynamics • Anyone interested in practical hydrogen blending analysis Software: Aspen HYSYS Topics Covered: Hydrogen reaction setup Material stream configuration Mixer (blending station) design Spreadsheet KPI tracking Adjust tool implementation Energy balance maintenance Emissions calculations What's Next?
