Hydrogen can be considered as an indirect greenhouse gas with the potential to increase global warming. The potential effects on climate from hydrogen-based energy systems would be much greater than from fossil fuels, according to the scientists.

Why is hydrogen not a greenhouse gas?
The heat in the atmosphere is produced by a greenhouse gas. It cannot leave the internal layer of the Earth’s atmosphere because it gets stuck in the environment. Pollution is caused by gases that affect the environment. Oxygen and hydrogens are not examples of pollutants.
Carbon dioxide (CO2) is a gas that is produced by the burning of fossil fuels such as coal, oil, and natural gas. CO2 is also emitted by plants and animals, as well as by human activities. Carbon dioxide is the main component of all the greenhouse gases, including methane (CH4), nitrous oxide (N2O), and ozone (O3).
The amount of each of these gases is measured in parts per million (ppm), which is equal to one part in 10,000 (1 ppm = 10 parts in a million) of air. This means that the concentration of a particular gas is directly proportional to its mass.
For example, if a molecule of methane has a mass of 1 ppm, then its concentration in air is 10 ppm.
Are hydrogen and helium greenhouse gases?
Water and non greenhouse gases make up over 99% of the gases in the atmosphere. Neon, hydrogen, and carbon monoxide are the only gases that make it into the air. The rest is water vapor, carbon dioxide, methane, ammonia, nitrous oxide, sulphur dioxide and nitrogen oxides. Water vapor is the most important greenhouse gas because it traps heat from the sun.
It is also responsible for the formation of clouds, which reflect sunlight back into space. Water vapor also acts as a refrigerant, helping to keep the Earth’s surface at a comfortable temperature. In addition, water vapour can be used to make plastics, paints, detergents, lubricants and many other products.
Is hydrogen harmful to the environment?
Hydrogen fuel does not produce the same amount of waste as fossil fuels. To produce usable hydrogen, it has to be separated from other non-renewable resources.
Hydrogen can be produced from a variety of renewable sources, including wind, solar, geothermal, biofuels, natural gas, coal, nuclear, hydroelectric, biogas, wind turbines, wave energy, tidal power, waste water treatment plants, landfill gasification, wood-burning stoves, biodiesel and ethanol production, as well as from fossil fuel-based fuels such as oil, gas and coal.
Is hydrogen a renewable?
The hydrogen fuel is considered to be renewable if the electricity comes from renewable sources. “Hydrogen is a renewable fuel, but it’s not renewable in the sense that it doesn’t have to come from fossil fuels.
Is NOx a greenhouse gas?
The conclusion is that emissions of NOx are a cause of global warming because they are not greenhouse gases. The burning of fossil fuels is the most important source of N2O emissions. The study was published in the journal Environmental Research Letters.
What are the 5 main greenhouse gases?
Carbon dioxide, methane, nitrous oxide, and water vapor are some of the main gases responsible for the greenhouse effect. Greenhouse gases can be removed from the atmosphere or trapped in the earth’s crust by different processes. Carbon dioxide is the most common greenhouse gas, but other gases, such as methane and nitrogen oxides, also contribute to global warming.
Greenhouse gas concentrations are measured in parts per million (ppm). The lower the number, the higher the concentration of the gas. For example, a measurement of 0.1 ppm is considered to be “safe” for human health and the environment, while a reading of 10,000 ppm would be considered “unhealthy” and “unsafe” to the human body.
