Borosilicate melted by natural gas/hydrogen blend
La Maison Française du Verre at its Châteauroux site producing borosilicate glass, has just completed its injection tests of up to 20% (in power) of hydrogen mixed in natural gas.
The company were able to validate this approach to decarbonisation at a true glass melting scale with a full load.
The Châteauroux internal teams and partners SEFPRO, Air Liquide, GRTgaz, Federation Cristal Verre, Federation Verre, with ADEME funding as part of the “France relance” project.
A team from Saint-Gobain Research Provence was also on site to study the feasibility of replacing a part of the natural gas used in the melting furnace with hydrogen and its impact on refractory blocks, combustion and the quality of glass.
The first results are very encouraging and fully in line with SEFPRO support for the transition to a decarbonized glass industry.
The rebuild of the Pyrex glass furnace in Châteauroux has now begun: technical teams are draining the furnace.
The work will be spread out until mid-August 2022 during the summer off-peak period.
La Maison Française du Verre has received €1.8 million support from funds dedicated to energy transition from Ademe, the French environment agency.
