It is the lightest element and, at standard conditions, is a gas of diatomic molecules with the formula H 2, sometimes called dihydrogen, but more commonly called hydrogen gas, molecular hydrogen or simply hydrogen.
May 5, 2024 · hydrogen (H), a colourless, odourless, tasteless, flammable gaseous substance that is the simplest member of the family of chemical elements. The hydrogen atom has a nucleus consisting of a proton bearing one unit of positive electrical charge; an electron, bearing one unit of negative electrical charge, is also associated with this nucleus.
Hydrogen is a clean fuel that, when consumed in a fuel cell, produces only water. Hydrogen can be produced from a variety of domestic resources, such as natural gas, nuclear power, biomass, and renewable power like solar and wind.
Sep 27, 2023 · Hydrogen is a naturally occurring gas, and it is the most abundant substance in the universe. (The word in Greek means “water former” because hydrogen creates water when burned.) Clean hydrogen is hydrogen produced with very low or zero carbon emissions.
As the world moves towards a low-carbon future, hydrogen provides a strategic pathway for Singapore to diversify our future energy mix, create new economic opportunities, and achieve net-zero emissions by 2050.
Jun 14, 2019 · In buildings, hydrogen could be blended into existing natural gas networks, with the highest potential in multifamily and commercial buildings, particularly in dense cities while longer-term prospects could include the direct use of hydrogen in hydrogen boilers or fuel cells.
It is used to synthesize ammonia, ethanol, aniline, and methanol; to treat petroleum fuels; as a reducing agent ( see reduction) and to supply a reducing atmosphere; to make hydrogen chloride ( see hydrochloric acid) and hydrogen bromide; and in hydrogenation (e.g., of fat s).
Dedicated hydrogen production today is primarily based on fossil fuel technologies, with around a sixth of the global hydrogen supply coming from “by-product” hydrogen, mainly in the petrochemical industry.
Hydrogen is a gas at normal temperature and pressure, but hydrogen condenses to a liquid at minus 423 o F (-253 o C). Hydrogen is an energy carrier. Energy carriers transport energy in a usable form from one place to another. Elemental hydrogen is an energy carrier that must be produced from another substance.
Feb 21, 2017 · Hydrogen is a clean fuel that, when consumed in a fuel cell, produces only water, electricity, and heat. Hydrogen and fuel cells can play an important role in our national energy strategy, with the potential for use in a broad range of applications, across virtually all sectors—transportation, commercial, industrial, residential ...
