The most abundant component in the universe , H is also a promising source of " light " fuel on Earth .
name after the Hellenic wordshydrofor " water " andgenesfor " forming , " atomic number 1 make up more than 90 pct of all of the corpuscle , which match three quarter of the mass of the universe , according to theLos Alamos National Laboratory . Hydrogen is essential for living , and it is present in nigh all the molecules in live on things , allot to theRoyal Society of Chemistry . The element also occurs in the stars and powers the universe through the proton - proton reaction and carbon - nitrogen cycle . Stellar hydrogen fusion mental process release huge total of energy as they immix H atoms to form He , according to Los Alamos .
The hydrogen atom has one proton and one electron.
double-dyed atomic number 1 gas is scarce in Earth ’s atmosphere and any hydrogen that in reality enters the atmosphere speedily break loose Earth ’s gravity , according to the Royal Society . On our major planet , hydrogen occur mainly in combination with oxygen and water supply , as well as in constitutional matter such as be plants , crude and coal , Los Alamos reports .
Just the facts
Hydrogen discovery
Robert Boyle acquire hydrogen gas in 1671 while he was experimenting withironand acids , but it was n’t until 1766 that Henry Cavendish recognise it as a distinct element , according toJefferson Lab . The element was named atomic number 1 by the Gallic apothecary Antoine Lavoisier .
Hydrogen has three common isotope : protium , which is just average H ; deuterium , a static isotope discovered in 1932 by Harold C. Urey ; and tritium , an fluid isotope discovered in 1934 , according to Jefferson Lab . The difference between the three isotopes lie in the number of neutron each of them has . Hydrogen has no neutrons at all ; deuterium has one , while tritium has two neutrons , according toLawrence Berkeley National Laboratory . Deuterium and tritium are used as fuel in atomic fusion reactor , according to Los Alamos .
Hydrogen blend with other elements , forming a number of chemical compound , including uncouth ones such as weewee ( H2O ) , ammonia ( NH3 ) , methane ( CH4 ) , mesa sugar ( C12H22O11 ) , atomic number 1 hydrogen peroxide ( H2O2 ) and hydrochloric dose ( HCl ) , according to Jefferson Lab .

Hydrogen is typically produced by heating instinctive gas with steam to form a admixture of H and carbon monoxide called syngas , which is then separated to bring out hydrogen , concord to the Royal Society .
Hydrogen is used to make ammonia for plant food , in a outgrowth called the Haber outgrowth , in which it is react with nitrogen . The element is also added to fats and oils , such as peanut rock oil , through a summons called hydrogenation , harmonise to Jefferson Lab . Other model of atomic number 1 habit admit rocket fuel , welding , producing hydrochloric acid , reduce metallic ore and filling balloon , fit in to Los Alamos . Researchers have been working on developing the hydrogen fuel cell technology that allows significant sum of electrical world power to be obtained using hydrogen gas as a befoulment - free source of energy that can be used as fuel for car and other vehicles .
Hydrogen is also used in the field glass diligence as a protective atmosphere for making flat ice sheets , while the electronics industriousness , it is used as a level gas in the physical process of manufacturing atomic number 14 cow dung , according to the Royal Society .

Current research
researcher have been studying hydrogen with great pastime for year because of its potential as a defilement - free fuel . " Hydrogen is an energy carrier with no carbon in it , so when you bite it , you only bring forth H2O , " which makes it a clean fuel , with no emissions at all , said Richard Chahine , the director of the Hydrogen Research Institute at University of Québec at Trois - Rivières in Canada . However , there is a major problem with H fuel : it is more expensive than gasoline . In fact , last year , Toyota ’s fourth-year frailty Chief Executive Bob Carter announced that , accord to the Department of Energy ’s estimates , a full tank of pack together hydrogen would initially cost around $ 50,Ecomento.comreported . In oecumenical , cost associate with hydrogen fuel technology are " a very thought-provoking barrier because , as of now , people would prefer to have better engineering at the ongoing Leontyne Price , " Chahine tell Live Science .
Another outcome with hydrogen fuel is that the process of hydrogen production itself is in fact not so " clear " or pollution free . " As of today , most of the hydrogen produced fare from lifelike flatulence , " a cognitive operation that bring forth carbon dioxide ( CO2 ) , Chahine said .
research worker have therefore been looking for alternative and more environmentally friendly ways of acquire H that would ideally eliminate CO2emissions from the process . Last twelvemonth , for instance , scientist at the U.S. Department of Energy ’s Argonne National Laboratory developed a small - plate " nano - sized hydrogen source , " a equipment that produces pure H using light and graphene and without burning fossil fuel . The current version of the source is really small , but if it turns out it can be expanded , it could permit scientist to farm enough atomic number 1 to leave fuel for machine and generators .
Another way of producing H , called " biologic H2O splitting , " would affect the use of sure photosynthetic microbes that apply light energy to produce H from water supply as part of their metabolic processes , allot to theNational Renewable Energy Laboratory , where researchers are currently investigating this process . Another potential method to produce atomic number 1 involves the fermentation of renewable biomass material , the NREL reports . research worker at the NREL have also been working on converting agricultural remainder ( such as goober pea shield ) and consumer wastes ( such as charge plate and wasteland grease ) into a liquid product called bio - oil whose components can then be single out into fuels , include hydrogen . The cleanest way to produce atomic number 1 , however , is through separate water into H and oxygen by using sunlight , the NREL reports .
