The objectives to be achieved within the H2GLASS project at Steklarna Hrastnik are:
Test the operation of two of its furnaces (oxyfuel and hybrid EP regenerative) with 100% H2 as fuel, aiming to reach 90% of the total energy used in the furnace
Maintaining high glass quality while reducing the use of natural gas to lower carbon dioxide emissions
Determine the effect of hydrogen combustion on the glass melting process and furnace
Enhance the integration of IT systems by creating a Computational Fluid Dynamics model of the glass furnace for techno-economic optimisation
