Green Hydrogen for Glass

Providing a zero emissions method of creating uniform glass

Hydrogen is employed to create an oxygen-free environment as a blanket to avoid oxidisation of the glass, preventing imperfections. However, green hydrogen can help decarbonise glass production.

Hydrogen is used in float glass processes to provide an atmosphere of 5-10% hydrogen in nitrogen.

Float glass is widely used to create high quality glass for automotive and buildings applications. 

Because of the way it is made, float glass is very flat, of uniform thickness, and contains no bubbles or distortions. 

Using green hydrogen generated from renewable sources rather than fossil fuels offers a solution for reducing the greenhouse gas emissions of float glass production.
