\nThe correct answer is C) All three.
\n<\/section>\n
\nGreen hydrogen, produced using renewable energy sources, is a key solution for decarbonizing heavy industries which are difficult to electrify and heavily reliant on fossil fuels.
\nFertilizer plants: Production of ammonia (NH3), a primary component of fertilizers, currently uses hydrogen derived mainly from natural gas (steam methane reforming), a process that emits significant CO2. Green hydrogen can directly replace this, making ammonia production carbon-free.
\nOil refineries: Hydrogen is used in refining processes like hydrocracking and hydrotreating to remove impurities and upgrade fuel products. Replacing grey hydrogen with green hydrogen is a direct pathway to reduce emissions in refineries.
\nSteel plants: Traditional steel production is a major source of CO2 emissions due to the use of coal as a reducing agent. Green hydrogen can be used as a reducing agent in direct reduced iron (DRI) processes, replacing coal and enabling the production of “green steel” with significantly lower emissions.
\n<\/section>\n
\nDecarbonizing heavy industries is crucial for achieving global climate goals. Green hydrogen offers a promising avenue as a clean fuel and feedstock, capable of reducing or eliminating process emissions in these sectors. Significant research, development, and pilot projects are underway globally to implement green hydrogen solutions in fertilizer, refining, and steel production.
