Hydrogen as a Potential New Source of Energy Combustion for Glass Melting

​​​​Clean hydrogen is one possible option to replace fossil fuels (notably NG or fuel oils) as feedstock, and significantly reduce GHG emissions. H2 combustion could be one feasible and efficient route toward decarbonization. Several options might emerge, stand-alone or combined, with the electrical melter, co-firing with Biogas or Hydrogen, heat recovery and ultimately Carbon capture (CCS). All these energies can be combined with oxy-combustion technology for better effectiveness.

A recent Air Liquide study, based on the LCA (life cycle analysis) approach, showed that one of the most effective solutions, economically and for CO2 reduction purposes, is the Hybrid furnace. It consists of using decarbonized electricity for one-half and for the other decarbonized H2, associated with heat oxy combustion technology. This solution would enable up to 78% CO2 reduction of emissions from the combustion process.

This Hybrid melting tank (electrical + H2 oxy-firing furnace, possibly combined with Air Liquide HeatOx solution) could be the solution to upgrade air-firing furnaces in use to produce container, flat and technical glass, while addressing more stringent environmental regulation.

The presentation will disclose the results of an Air Liquide study regarding CO2 reduction efficiencies and operating cost of glass production for H2 combustion produced through different technologies.

Other applications for H2 to fight climate change.

As part of its climate objectives, Air Liquide is working with its customers to develop low carbon solutions for a sustainable industry. For example, the Group is developing innovative projects with its steel industry customers. The use of hydrogen in the blast furnace during steel production could reduce CO2 emissions in the production process by up to 20%.

Air Liquide is also promoting the use of Hydrogen energy for clean mobility. Used with a fuel cell, hydrogen combines with the oxygen present in air to produce electricity and move cars, forklifts, trains or trucks forward. Without any emissions nor particles.
