The industrial sector, a major contributor to global carbon emissions, is finding innovative ways to integrate green hydrogen into its processes. This shift is not only reducing the carbon footprint of heavy industries but also opening up new avenues for sustainable production methods.

Steel manufacturing turning to hydrogen reduction

The steel industry, traditionally one of the largest emitters of CO2, is at the forefront of adopting green hydrogen technology. Hydrogen-based direct reduction of iron ore is emerging as a promising alternative to traditional coal-based processes. This method uses hydrogen as a reducing agent, producing water vapor instead of CO2 as a byproduct. Several major steel producers have already begun pilot projects using hydrogen reduction. For example, a plant in Sweden has successfully produced fossil-free steel using hydrogen technology, marking a significant milestone in the industry's decarbonization efforts. Experts predict that by 2030, hydrogen-based steel production could account for up to 10% of global steel output.

Ammonia synthesis using renewable hydrogen feedstock

Ammonia production, a key process in the fertilizer industry, is another area where green hydrogen is making significant inroads. Traditionally, ammonia synthesis relies on hydrogen derived from natural gas, a process that generates substantial CO2 emissions. By switching to green hydrogen as a feedstock, the industry can dramatically reduce its carbon footprint. Several large-scale projects are underway to produce "green ammonia" using renewable hydrogen. These initiatives not only address the environmental concerns associated with ammonia production but also open up new possibilities for using ammonia as a hydrogen carrier for energy storage and transportation.
