Speciality glass manufacturer Schott has begun its large-scale tests on how to power its melting tanks with hydrogen.
Over a period of one month, R&D experts will gradually increase the ratio of hydrogen in the melt up to 35% at Schott's headquarters in Mainz, Germany.
Schott launched the project earlier this year in an aim to manufacture carbon neutral glass.
The project is supported by partners including the European Union, Mainzer Stadtwerke, Staatskanzlei Rheinland-Pfalz, and the Environmental Ministry of Rheinland-Pfalz.
