Hydrogen’s role in gas turbine technology
A futuristic ZEISS facility is situated near offshore wind turbines with glowing blue lines.

As the global energy landscape shifts toward sustainable and low-carbon solutions, hydrogen (H2) is emerging as a promising fuel source for gas turbines. The transition to hydrogen not only aligns with climate goals, but also serves as a versatile energy solution that can complement renewable energy sources, providing power during dark doldrums or easing peak loads in the grid. However, to realize the full potential of hydrogen, gas turbines must be prepared to use H2 instead of fossil fuels.

Key challenges in achieving H2 readiness

H2 compatibility is key to ensuring that gas turbines can operate safely and efficiently on hydrogen. This involves overcoming technical challenges such as high combustion temperatures, advanced materials, and special coatings. Given the unique combustion characteristics of hydrogen, modifications to turbine design and processes are essential to optimize the performance and reliability of future hydrogen-powered plants.

One of the biggest challenges in converting gas turbines to hydrogen as a fuel is the high temperatures generated during combustion. Hydrogen generates higher temperatures during combustion than natural gas, which leads to increased thermal stress on the turbine components. Modern materials must therefore be used that can withstand these high temperatures without compromising structural integrity.

Blades and vanes: Critical components for efficiency

The blades and vanes of gas turbines are crucial for efficient energy conversion and must be designed to handle the unique challenges posed by hydrogen combustion. Manufacturing and assembling these components requires precise inspection techniques, such as geometric dimensioning and tolerancing (GD&T), to maintain tight tolerances. Advanced materials, such as high-temperature alloys and ceramics, are essential for ensuring durability and performance under extreme conditions.

Thermal barrier coatings: A game changer for performance and longevity
Special coatings protect blades and vanes from oxidation and wear, particularly in high-temperature environments. Thermal barrier coatings (TBCs) are especially important in the context of H2 operation. TBCs are applied to the surfaces of turbine components to thermally insulate them, allowing them to operate at higher temperatures without experiencing thermal fatigue or degradation. This is why quality assurance is particularly important here.

The role of ZEISS Solutions in quality assurance
The implementation of innovative and reliable production methods and maintenance, repair, and overhaul (MRO) processes for H2-compatible turbine components is of the utmost importance. End-to-end quality assurance processes play a vital role. They ensure the long-term success and reliability of these technologies. High-precision data for complex shapes and internal structures is essential for maintaining tight tolerances, especially in critical areas such as cooling channels and combustion zones. ZEISS offers advanced measurement technologies – such as ZEISS ScanBox and ATOS 5 for Airfoils, ZEISS PRISMO and ZEISS Microscopy Solutions – to ensure the highest levels of component quality.

During MRO, IGT blades are inspected and recoated for future service.

ZEISS Software: Early analysis for reliability
The fast, accurate, and reliable measurement systems and their powerful control and analysis software solutions like ZEISS INSPECT and ZEISS CALYPSO can identify potential quality problems early in the production process. This minimizes the risk of failure during operation of the gas turbine and increases the service life of its components. By ensuring the quality standards of each individual component, ZEISS Solutions make an important contribution to the reliability and overall efficiency of hydrogen-powered gas turbines.

Doncasters: Global leader in turbine blade manufacturing

Founded in 1778 by Daniel Doncaster in Sheffield, UK, Doncasters has evolved from a tool foundry into a leading global supplier of industrial gas turbines and aerospace applications.

Quality, reliability, and safety are critical in the production of turbine blades as even small defects can lead to failure. For over 14 years, Doncasters in Bochum, Germany, has employed optical measurement technology to capture complex blade geometries, such as those used in industrial gas turbines. The company uses two ATOS 5 sensors for 3D data acquisition, one manual for verifying the wax models and a second in a ZEISS ScanBox for final inspection before shipping. Dr. Jens Vrenegor, Head of 3D Metrology, explains, “With the ATOS 3D scanners, we can accelerate measurement times by a factor of two to three while completely scanning critical products.” Committed to innovation, Doncasters is increasingly digitizing processes and using optical 3D metrology to streamline operations, minimize waste, and ensure quality turbine blades.
