Hydrogen is the lightest and most abundant element in the universe. It’s also a great source of energy. Did you know that the sun is 70% hydrogen? Here on Earth, it is commonly known as a green fuel because it produces only water when burned which makes it a promising alternative to fossil fuels. Hydrogen is primarily produced through three methods: electrolysis, which splits water into hydrogen and oxygen using electricity; steam methane reforming (SMR), the most common and cost-effective method but one that emits carbon dioxide; and coal gasification, which also releases significant CO₂ emissions. Despite its environmental benefits, the challenge remains in making green hydrogen affordable and scaling up production.
Hydrogen is widely used in petroleum refining to remove sulfur from crude oil, in steel and metal production as a reducing agent, and in glass manufacturing to prevent oxidation. In the energy sector, hydrogen fuel cells power vehicles, trains, and even aeroplanes, providing a zero-emission alternative to conventional fuels. It is a key component in ammonia production for fertilisers, methanol manufacturing, and hydrogen peroxide production for industrial cleaning and bleaching. The food industry utilises hydrogen for hydrogenating fats and oils, while the electronics sector relies on it for semiconductor fabrication.
The environmental impact of hydrogen is variable. Green hydrogen, derived from electrolysis using renewable energy, generates zero emissions and can significantly reduce reliance on fossil fuels. It has the potential to decarbonise transportation, power generation, and industrial sectors. However, current hydrogen production is dominated by SMR and coal gasification, which release large amounts of CO₂. Additionally, hydrogen leakage poses climate risks, as it can extend the atmospheric lifetime of methane, a potent greenhouse gas.
Safety is a critical consideration when handling hydrogen due to its highly flammable nature. To prevent fires and explosions, it must be stored in high-pressure cylinders, kept away from open flames, and handled using specialized leak-proof piping. Hydrogen flames are nearly invisible in daylight, making thermal cameras essential for fire detection. Safety measures include wearing flame-resistant clothing, using gas detectors, and implementing strict leak detection protocols.
