Fundación Tecnalia Research and Innovation (TECNALIA) is the first private applied research centre in Spain and the 5th in Europe. In the field of compatibility of materials with hydrogen, TECNALIA studied the effects of hydrogen on materials in industrial processes (oil & gas, chemical industry, …) over the last two decades, but it has not been until the recent boom in hydrogen as an energy carrier when the research focused on the compatibility of hydrogen with the components of gas grids. During the last year, TECNALIA contributed to some of the main EU funded projects related to the study of the compatibility of gas distribution grids with hydrogen, such HIGGS, SHIMMER or PILGRHYM. On the private side, TECNALIA is actively collaborating with its clients in this field in projects related to distribution and storage of hydrogen
