how many of the above industries?
(a) Only one
(b) Only two
(c) All three
(d) None
Answer: (c)
- Fertiliser plants: Green hydrogen can be used as a clean source of energy for the production of fertilisers. Hydrogen is a key component in the manufacturing of ammonia, which is used as a primary raw material in the production of nitrogen-based fertilisers. By utilising green hydrogen instead of traditional hydrogen derived from fossil fuels, the fertiliser industry can reduce its carbon emissions and contribute to decarbonization efforts.
- Oil refineries: Green hydrogen can be utilised in oil refineries as a clean energy source for various processes. It can be used in hydrogenation processes to produce cleaner fuels with lower sulphur content, as well as for desulfurization and hydrocracking operations. By incorporating green hydrogen, oil refineries can reduce their reliance on fossil fuels and minimise their carbon footprint.
- Steel plants: Green hydrogen has the potential to revolutionise the steel industry by replacing the conventional use of coal in blast furnaces. Currently, the production of steel through the traditional blast furnace route is a significant source of carbon dioxide emissions. By using green hydrogen as a reducing agent instead of coal, it becomes possible to produce “green steel” with substantially lower carbon emissions. This process, known as direct reduction, has the potential to significantly decarbonize the steel industry
