STA for Hydrogen Application

Simultaneous Thermal Analysis – Safe examination of materials under hydrogen

Infos / Datasheet

Hydrogen (H2) is gaining attention or its potential role in sustainable practices and green technology. Research into the interaction of materials with hydrogen is critical for developing eco-friendly solutions that can significantly reduce environmental impact.

The H2Secure concept developed by NETZSCH features a complete solution for conducting tests in environments with varying concentrations of hydrogen while providing utmost safety. This concept enables safe experimentation in a 100% H2 environment or with lower concentrations of H2 mixed with non-flammable gases such as nitrogen (N2) or argon (Ar) atmospheres. This flexibility is achieved through a comprehensive safety protocol embedded in the system.


Functional principle:

Simultaneous Thermal Analysis (STA) generally refers to the simultaneous application of Thermogravimetry (TGA) and Differential Scanning Calorimetry (DSC) to one and the same sample in a single instrument. The advantages are obvious: The test conditions are perfectly identical for the TGA and DSC signals (same atmosphere, gas flow rate, vapor pressure on the sample, heating rate, thermal contact to the sample crucible and sensor, radiation effect, etc.). Furthermore, sample throughput is improved as more information can be gathered from each test run.


STA 449 / 509 Series supports with:

  • Oxidation-reduction cycles without interrupting the measurement
  • Analysis of the reaction kinetics
  • Investigation of direct reduction, e.g. of metallurgical processes
  • Determination of volumetric and gravimetric capacities, e.g. for H2 energy storage solutions
  • Adsorption/desorption kinetic
  • Investigation of the life cycle of materials
