Hydrogen is widely used in various industrial processes, such as:

  • Synthesis of ammonia: Hydrogen reacts with nitrogen to produce ammonia, which is a key ingredient for fertilizers and explosives. Ammonia synthesis is one of the largest consumers of hydrogen in the world.
  • Hydrogenation of oils: Hydrogen is used to convert liquid vegetable oils into solid fats, such as margarine and shortening. This process improves the shelf life and texture of the oils.
  • Refining of petroleum: Hydrogen is used to remove sulfur and other impurities from crude oil, and to enhance the quality and octane rating of gasoline and diesel.
  • Production of methanol: Hydrogen reacts with carbon monoxide to produce methanol, which is a versatile chemical that can be used as a fuel, solvent, or feedstock for other chemicals.

Hydrogen is also a promising source of clean and renewable energy, as it can be produced from water and other abundant resources. It can be converted into electricity or heat with zero emissions. Some of the energy uses of hydrogen are:

  • Fuel cells: Fuel cells are devices that convert the chemical energy of hydrogen and oxygen into electricity and water. Fuel cells can be used to power vehicles, homes, and businesses, as well as to provide backup power for critical facilities.
  • Hydrogen vehicles: Hydrogen vehicles are vehicles that use hydrogen as a fuel, either in internal combustion engines or in fuel cells. Hydrogen vehicles have the advantage of producing only water as a byproduct and can offer a longer driving range and faster refueling than battery-electric vehicles.
  • Power-to-gas: Power-to-gas is a process that converts excess electricity from renewable sources, such as wind and solar, into hydrogen, which can be stored or injected into the natural gas grid. This can help balance the supply and demand of electricity and reduce the dependence on fossil fuels.

Hydrogen also has some medical uses, such as:

  • Hydrogen inhalation: Hydrogen inhalation is a therapy that involves breathing in a mixture of hydrogen and oxygen gas. It can have anti-inflammatory, antioxidant, and neuroprotective effects and can help treat various diseases, such as stroke, heart attack, and lung injury.
  • Hydrogen water: Hydrogen water is water that contains dissolved hydrogen gas. It can have similar benefits as hydrogen inhalation and can also improve hydration, metabolism, and skin health.
  • Hydrogen peroxide: Hydrogen peroxide is a compound comprising hydrogen and oxygen. It can be used as an antiseptic, disinfectant, and bleaching agent, as well as to treat minor wounds, infections, and acne.

Space Exploration Uses of Hydrogen

Hydrogen is also essential for space exploration, as it can provide both propulsion and power for spacecraft, such as:

  • Rocket fuel: Hydrogen is the most efficient rocket fuel, as it has the highest specific impulse and the lowest molecular weight. Hydrogen can be combined with oxygen or other oxidizers to produce a powerful thrust and a large amount of water.
  • Space station: Hydrogen is used to generate electricity and water for the International Space Station (ISS). The ISS has fuel cells that use hydrogen and oxygen to produce electricity, and electrolyzers that use electricity to split water into hydrogen and oxygen. The hydrogen and oxygen can then be stored or recycled for future use.

Benefits of Hydrogen

Hydrogen not only has many uses but also many benefits for humanity and the planet. Here are some of the benefits of hydrogen that you should know:

  • Environmental benefit: Hydrogen can help reduce greenhouse gas emissions and air pollution, as it only produces water and heat when used in fuel cells or combustion engines. Hydrogen can also be produced from renewable sources, such as solar, wind, and biomass, which have lower environmental impacts than fossil fuels. For instance, the European Union has set a target to produce 10 million tonnes of renewable hydrogen by 2030, which could save up to 170 million tonnes of CO2 emissions per year.
  • Health benefit: Hydrogen can improve human health by reducing exposure to harmful pollutants, such as nitrogen oxides, particulate matter, and carbon monoxide, which can cause respiratory and cardiovascular diseases. Hydrogen can also have therapeutic effects, such as anti-inflammatory, antioxidant, and neuroprotective, when inhaled or consumed as water. For example, a clinical trial in Japan showed that hydrogen water can improve the quality of life and cognitive function of patients with Parkinson’s disease.
  • Energy security benefit: Hydrogen can enhance energy security by diversifying the energy supply and reducing the dependence on imported fossil fuels. Hydrogen can also be stored and transported in various forms, such as gas, liquid, or solid, and used for different purposes, such as electricity, heat, or mobility. For example, Australia is planning to export hydrogen to Japan and other Asian countries, using its abundant solar and wind resources.


Hydrogen is a versatile and valuable element that has many uses in different fields. It can be used to synthesize important chemicals, produce clean and renewable energy, treat various medical conditions, and explore outer space. Hydrogen can also help reduce greenhouse gas emissions and dependence on fossil fuels, and thus contribute to a sustainable and prosperous future for humanity.
