Demystifying hydrogen

Hydrogen, when produced from renewable sources like green hydrogen, plays a critical role in reducing carbon emissions in sectors that are difficult to electrify, such as heavy industry and transportation. As a fuel, hydrogen emits only water as a byproduct, providing a clean alternative to fossil fuels and significantly contributing to decarbonisation efforts.

Hydrogen serves as a valuable tool for energy storage, especially when paired with intermittent renewable sources like wind and solar, enabling long-term storage of energy and stabilising the supply over both short- and longer-term (e.g. seasonal) periods. Additionally, hydrogen helps balance the grid by converting excess renewable energy into storable hydrogen, which can later be reconverted to electricity or used in various applications.

Hydrogen offers solutions for industrial processes that require high-temperature heat, such as steelmaking, cement production, and chemical manufacturing, where electrification is challenging. It also acts as a versatile feedstock in chemical processes like ammonia production and refining, providing a cleaner alternative to traditional methods.

Hydrogen enhances energy security by diversifying the energy mix and reducing reliance on imported fossil fuels. It can be produced locally using renewable energy, which bolsters energy independence and mitigates geopolitical risks associated with energy imports.

The transition to hydrogen stimulates technological innovation in fields such as fuel cells, electrolysers, and hydrogen storage, driving advancements in engineering and manufacturing. This shift is also expected to generate new jobs and economic opportunities in renewable energy, manufacturing, and infrastructure development.
