Preparing for Sustainable Glass Production – Technical and Economic Investigation of Hydrogen Supply for Glass Melting
To qualify glass operations to be CO2 – free, clean hydrogen production with low carbon intensity must be used. Two common clean H2 production methods currently under consideration are NG-based steam methane reforming with carbon capture and sequestration (blue H2) as well as electrolysis with renewable power (green H2).
H2 requirements will be determined by multiple factors including furnace size, number of furnaces and cullet rates. Techno-economic assessments for use of clean H2 will be presented. Factors affecting techno-economic feasibility are NG prices and potential for CO2 sequestration and/or CO2 utilization for blue H2 and availability and prices of renewable power for green H2.
