Next-Generation Gas Turbine Blades: Cooling Strategies, Material Development, and Failure Prevention

The International Energy Agency (IEA) predicts global energy demand will rise by 1.7% annually from 2000 to 2030, reaching roughly two-thirds of current levels.To use sustainable fuels, modern turbo-machinery must offer high specific power, better electrical efficiency, lower investment costs, minimal pollution, and reduced maintenance.As independent power producers grow in competitiveness, flexible plants with higher efficiency can meet fluctuating demand.Cooling techniques can boost efficiency to about 60%.The combined cycle gas turbine (CCGT) is currently the most efficient large-scale power system, with thermal efficiency at 64% (LHV), cutting CO2 emissions to onethird of coal plants.However, CCGTs still require further advancements to achieve carbon neutrality by 2050.
