Hydrogen Embrittlement of X52 Electrolytically Charged Pipeline Steel
Original language description
Burning fossil fuels releases greenhouse gases into the atmosphere, causing global warming and climate change. Reducing climate impacts can be achieved by switching to carbon-free energy sources, and hydrogen as a carbon-free energy carrier can be a key parameter. The use of a mixture of natural gas and hydrogen is a much-discussed option. The use of this mixture in industry, e.g. as fuel for gas-fired power plants, would lead to a lower environmental burden due to reduced greenhouse gas emissions. Efficient and economically acceptable distribution of hydrogen is important. The best option is to transport the gas using existing pipeline systems. Hydrogen degrades the mechanical properties of most structural metal materials, especially steel. Describing the degradation of materials exposed to a hydrogen environment is a key parameter for the use of existing natural gas transport infrastructure. For the experiment, X52 steel was used, which is the base material for the natural gas distribution network. Electrolytic saturation was used to charge the material with hydrogen. Different saturation times were tested. The mechanical properties were determined by the notch impact test.
