CEMENT
CEMENTDecarbonize Cement with Green Hydrogen
Cement production is responsible for approximately 8% of global CO2 emissions. Green hydrogen provides pathways for kiln fuel substitution and utilization of process CO2 emissions.
Membrane Cross-Section
PSU-TiO₂-GOKiln Fuel Switching
Green hydrogen can partially replace fossil fuels in cement kilns, directly reducing combustion-related CO2 emissions without major modifications to existing kiln systems.
CO2 Utilization Enabler
Cement plants produce concentrated CO2 from calcination. Green hydrogen enables conversion of this CO2 to synthetic fuels or chemicals via Power-to-X pathways.
Cost-Effective H2 Supply
IONZERA's 3x lower area resistance reduces the cost of green hydrogen, improving the economics of both fuel switching and CCU pathways for cement decarbonization.
The Cement Decarbonization Challenge
Cement is the most widely used construction material on Earth, with over 4 billion tonnes produced annually. The production process generates CO2 from two sources: combustion of fossil fuels to heat the kiln to approximately 1,450 degrees C, and the calcination reaction itself (CaCO3 to CaO + CO2). The calcination emissions cannot be eliminated by fuel switching alone, making cement one of the hardest-to-abate industrial sectors.
Green hydrogen addresses cement emissions through two complementary pathways: partial replacement of fossil kiln fuels with hydrogen, and utilization of captured CO2 by reacting it with green hydrogen to produce synthetic fuels or chemicals.
Hydrogen Pathways for Cement Plants
IONZERA-equipped electrolysers can support multiple decarbonization strategies for cement production:

India's Cement Industry
India is the world's second-largest cement producer, with over 350 million tonnes per year. As Indian cement companies face growing pressure to decarbonize, IONZERA, manufactured locally by G-Hexa, provides a domestic source for the efficient electrolyser membranes needed to produce green hydrogen at cement plant scale. This alignment between local membrane manufacturing and local cement industry demand creates a natural pathway for hydrogen adoption in Indian cement production.
