Because H 2 is the lightest element, atmospheric H 2 can readily be lost to space via Jeans escape, an irreversible process that drives Earth's net mass loss. [7] Photolysis of heavier compounds not prone to escape, such as CH 4 or H 2 O, can also liberate H 2 from the upper atmosphere and contribute to this process.
Dihydrogen monoxide is a name for the water molecule, which comprises two hydrogen atoms and one oxygen atom (H 2 O).. The dihydrogen monoxide parody is a parody that involves referring to water by its unfamiliar chemical systematic name "dihydrogen monoxide" (DHMO, or the chemical formula H 2 O) and describing some properties of water in a particularly concerning manner — such as the ...
Interest is high in this technology because H 2 is a clean fuel and can be readily produced from certain kinds of biomass, [2] including biological waste. [3] Furthermore some photosynthetic microorganisms are capable to produce H 2 directly from water splitting using light as energy source.
Modelling suggests that enough natural hydrogen exists to meet humanity's demand for hydrogen for thousands of years, however most of this cannot be extracted economically. [ 5 ] [ 6 ] Natural hydrogen has been identified in many source rocks in areas beyond the sedimentary basins where oil companies typically operate.
The cycle can be performed with any source of very high temperatures, approximately 950 °C, such as by Concentrating solar power systems (CSP) and is regarded as being well suited to the production of hydrogen by high-temperature nuclear reactors, [102] and as such, is being studied in the High-temperature engineering test reactor in Japan.
Hydrogen can be used in fuel cells to produce electricity, or burned to generate heat. [153] When hydrogen is consumed in fuel cells, the only emission at the point of use is water vapour. [153] When burned, hydrogen produces relatively little pollution at the point of combustion, but can lead to thermal formation of harmful nitrogen oxides. [153]
In its pure form it may be called tritium oxide (T 2 O or 3 H 2 O) or super-heavy water. Pure T 2 O is a colorless liquid, [1] and it is corrosive due to self-radiolysis. Diluted, tritiated water is mainly H 2 O plus some HTO (3 HOH). It is also used as a tracer for water transport studies in life-science research
