Project Update

The project has been initiated. Team is working on 1) gathering the baseline energy measurements, and 2) preparing for equipment procurement. Gallo Glass experienced delays due to COVID-19 outbreak and is currently revising their project schedule to make up for these delays. Team believes that the project will be finished within the agreement timeframes.

The Issue

Nitrogen constitutes almost 80 percent of air used for combustion. It is inert and does not participate in combustion but is heated and rejected to the atmosphere with the flue gases adding to energy losses. Increasing oxygen content of the air used for combustion improves efficiency of the heating process.

Project Innovation

The purpose of the project is to demonstrate an economically viable advanced oxygen-enriched combustion system (Advanced Oxy-Fuel Combustion Glass Melting System (AOGM)) at Gallo Glass Company (Gallo Glass), a glass manufacturer in the California industrial sector. Gallo Glass will partner with Linde, which will provide the proposed technology, measure the performance, and transfer the demonstrated technology to the broader glass market.

Project Benefits

This project will result in ratepayer benefit of reduced natural gas consumption of approximately 25 percent, directly leading to lower utility costs. A 25 percent reduction in O2 requirements as a result of this project will also lower electricity consumed in oxygen production by ~140 kW, which also will result in lower electricity costs. [br /]
This project will lead to technological advancement and breakthroughs to overcome barriers to the achievement of the State of California's statutory energy goals by demonstrating technology at a major natural gas user that will reduce carbon emissions from natural gas sources, helping to achieve AB32's goals of 40 percent lower CO2 generation from 1990 levels by 2030.

Lower Costs


Advanced combustion technology is anticipated to decrease natural gas consumption on the installed glass furnace by 25 percent.

Environmental & Public Health

Environmental Sustainability

Advanced combustion technology is anticipated to reduce NOx and CO2 emissions from combustion also by 25 percent, as compared with the state of the art oxy-fuel combustion process currently used for glass melting.
