What is hydrogen?

Hydrogen is a chemical element with the symbol H and atomic number 1. It is the lightest and most abundant element in the universe, making up about 75% of its elemental mass. Hydrogen is the primary building block of the universe, formed shortly after the Big Bang.

In its most common form, hydrogen consists of a single proton and a single electron. It is the simplest and lightest element, and it is odourless, colourless, and highly flammable. Hydrogen has the lowest boiling point and density of any known substance.

Hydrogen is versatile and has numerous applications in various industries. Some key uses of hydrogen include:

  • Fuel: Hydrogen can be used as a clean and efficient fuel in fuel cells to produce electricity. When hydrogen combines with oxygen in a fuel cell, the only byproduct is water, making it a potentially sustainable and environmentally friendly energy source.
  • Chemical production: Hydrogen is used in the production of various chemicals, including ammonia, methanol, and petroleum products. It is an essential component in industries such as fertilisers, pharmaceuticals, and refineries.
  • Hydrogenation: Hydrogen is used in the hydrogenation process to convert unsaturated fats and oils into saturated fats, making it important in the food industry for the production of margarine, shortening, and other products.
  • Metal refining: Hydrogen is used in the refining of metals, such as removing impurities from steel and other alloys. It can also be used in the production of electronics, semiconductors, and other high-tech materials.
  • Aerospace: Hydrogen is used as rocket fuel for space exploration due to its high energy content and the ability to react with oxygen in a combustion chamber.

In recent years, hydrogen has gained increased attention as a potential solution for decarbonizing energy systems and reducing greenhouse gas emissions. It is seen as a promising alternative to fossil fuels in transportation and energy storage, with ongoing research and development focused on improving hydrogen production, storage, and utilisation technologies.

How much does hydrogen weigh?

In terms of atomic mass, the atomic weight of hydrogen is approximately 1.008 atomic mass units (u) or 1 gram per mole (g/mol). This represents the average mass of a hydrogen atom.

In terms of weight per volume, the density of hydrogen gas depends on the temperature and pressure conditions. At standard temperature and pressure (STP), which is defined as 0 degrees Celsius (273.15 Kelvin) and 1 atmosphere of pressure, the density of hydrogen gas is approximately 0.0899 grams per litre (g/L) or 0.0899 kilograms per cubic metre (kg/m³).

It's worth noting that hydrogen is the lightest and least dense element, making it significantly lighter than most other gases. Its low density contributes to its ability to quickly disperse and rise in the atmosphere.

What is the energy content of hydrogen?

The energy content of hydrogen is typically measured in terms of its higher heating value (HHV) or lower heating value (LHV).

The higher heating value represents the total energy content of hydrogen, assuming that the water produced from the combustion process remains in a vapour state. It is approximately 141.9 megajoules per kilogram (MJ/kg) or 3.54 kilowatt-hours per normal cubic metre (kWh/Nm³) or 39.5 kilowatt-hours per kilogram (kWh/kg).

The lower heating value takes into account the energy required to convert the water vapour back into a liquid state. It is slightly lower than the higher heating value and is approximately 120.7 megajoules per kilogram (MJ/kg) or 3.00 kilowatt-hours per normal cubic metre (kWh/Nm³) or 33.5 kilowatt-hours per kilogram (kWh/kg)

These values indicate the amount of energy that can be released by burning hydrogen as a fuel or by utilising it in a fuel cell to generate electricity. Hydrogen has a high energy content per unit mass, making it an attractive option for various energy applications.

Is hydrogen safe?

Hydrogen is generally considered safe when handled and used properly. However, there are certain safety considerations associated with hydrogen due to its unique properties:

  • Flammability: Hydrogen is highly flammable and can ignite easily. It has a wide flammability range in air (4% to 75% by volume), meaning that even a small concentration of hydrogen mixed with air can be combustible. Special precautions must be taken to prevent leaks, control ignition sources, and ensure proper ventilation in hydrogen storage, handling, and usage.
  • Explosive Limits: Hydrogen forms explosive mixtures with air or oxygen. When hydrogen concentrations are within the flammable range and there is an ignition source present, it can lead to a rapid combustion or explosion. This highlights the need for careful monitoring and control of hydrogen concentrations in confined spaces or areas where leaks may occur.
  • Leak Hazards: Hydrogen has small molecular size and can easily leak through small gaps or cracks. Leak detection systems and proper sealing of hydrogen storage and transportation systems are essential to prevent potential hazards.
  • High-Pressure Handling: Hydrogen is often stored and transported under high pressure, which requires appropriate engineering and safety measures to prevent ruptures or leaks in the equipment and piping systems.
  • Embrittlement: Hydrogen can cause embrittlement in certain materials, particularly metals. It can lead to structural weaknesses and failures over time. Proper material selection is crucial for hydrogen infrastructure to prevent embrittlement issues.
  • Asphyxiation Risk: While not toxic, hydrogen can displace oxygen in an enclosed space, potentially leading to oxygen depletion. Proper ventilation and monitoring of oxygen levels are necessary when working with hydrogen in confined areas.

It is important to note that safety practices, guidelines, and regulations exist to mitigate the risks associated with hydrogen. Adequate training, proper equipment design, strict adherence to safety protocols, and regular maintenance are essential to ensure safe handling and usage of hydrogen.

Does hydrogen have an expiration date?

Hydrogen itself does not have an expiration date in the sense of a chemical degradation or decay over time. It is a stable element and does not undergo radioactive decay or other processes that would cause it to degrade naturally.
