Hydrogen economy. Hydrogen has the most potential to reduce greenhouse gas emissions when used in chemical production, refineries, international shipping, and steelmaking [ 1] The hydrogen economy is an umbrella term for the roles hydrogen can play alongside low-carbon electricity to reduce emissions of greenhouse gases.
In this process, hydrogen is produced from a chemical reaction between steam and methane, the main component of natural gas. Producing one tonne of hydrogen through this process emits 6.6–9.3 tonnes of carbon dioxide. [ 3] When carbon capture and storage is used to remove a large fraction of these emissions, the product is known as blue hydrogen.
01:37. Newly appointed Starbucks CEO Brian Niccol won’t be required to relocate to the company’s headquarters in Seattle when he joins the coffee giant next month. Instead, Starbucks says ...
Hydrogen is the only element whose isotopes have different names that remain in common use today: the 2. H. (or hydrogen-2) isotope is deuterium [ 6] and the 3. H. (or hydrogen-3) isotope is tritium. [ 7] The symbols D and T are sometimes used for deuterium and tritium.
Hydrogen is a chemical element; it has symbol H and atomic number 1. It is the lightest element and, at standard conditions, is a gas of diatomic molecules with the formula H2, sometimes called dihydrogen, [ 11] but more commonly called hydrogen gas, molecular hydrogen or simply hydrogen. It is colorless, odorless, tasteless, [ 12] non-toxic ...
A thermonuclear weapon, fusion weapon or hydrogen bomb ( H bomb) is a second-generation nuclear weapon design. Its greater sophistication affords it vastly greater destructive power than first-generation nuclear bombs, a more compact size, a lower mass, or a combination of these benefits. Characteristics of nuclear fusion reactions make ...
Hydrogen peroxide is a chemical compound with the formula H 2 O 2.In its pure form, it is a very pale blue [5] liquid that is slightly more viscous than water.It is used as an oxidizer, bleaching agent, and antiseptic, usually as a dilute solution (3%–6% by weight) in water for consumer use and in higher concentrations for industrial use.
A hydrogen vehicle is a vehicle that uses hydrogen to move. Hydrogen vehicles include some road vehicles, rail vehicles, space rockets, forklifts, ships and aircraft. Motive power is generated by converting the chemical energy of hydrogen to mechanical energy, either by reacting hydrogen with oxygen in a fuel cell to power electric motors or ...
