HYDROGENTECHNOLOGIES Themostcommonelementintheuniverse,hydrogen, haslong beenhailedasapromisingcleanfuelfor the future.Thatfuturemightbecloser than everthankstomassiveinvestments madein hydrogen research anddevelopmentby energyand automakers.

Hydrogenandoxygenreactchemicallytoproduceelectricity inhydrogenfuel cells;the only byproductis water.Becauseofthis, hydrogenproducedusingrenewableenergy sources like solar andwind hasno emissions.Today'sroad-worthyhydrogenfuel cell vehiclesareproducedbyToyota,Honda,Hyundai,and other automakers.However, alackofinfrastructure forrefuelinghaspreventedbroaderadoption. Now,ifslowly,thatinfrastructureisbeginningtoappear.Lessthan50 publichydrogenfillingstationscan befound intheUSatthemoment,mostof themare in California,wherelawsfavorzero-emissioncars. Over thenext ten years, energycompaniessuchasShelland BP haveannounced planstorapidlyexpand the number ofhydrogenstations in thenation. Production-wise,electrolysistechniquesfor removing hydrogenfromwaterarebecomingmore advanced.Modularelectrolyzers thatrunonrenewableenergyhavebeendevelopedbystartups.So- called"greenhydrogen"is gettingclosetochallengingconventionalhydrogenproductionfromnatural gas assolarandwindpowerbecomemore affordable. Significantinfrastructurelegislationenactedlast year alsoincrease federalfundingforthestudy and development ofhydrogen. Within thenextten years, theDepartment ofEnergy wantstocutthe price of cleanhydrogenby 80%. Butproblemsstillexist.Large-scalehydrogenfuel transportation and storageneednewstoragetanks, pipelines,and otherinfrastructure.Also,thecostofhydrogenfuelcellcarsisstill higherthanthat of gasoline-powered ones. Whether hydrogenbecomesacommonfuelis stillup in theair.However,asmore carmanufacturersand energy giantsplacesignificantbetson hydrogen,thiscleanerfuelmightfinally have achancetopower thefuture. Hereis anoverviewexplaining some keyhydrogentechnologies: HydrogenFuelCells: Hydrogenandoxygenundergoanelectrochemicalreactionin fuelcellsto produce electricity.Fuelcells are emission-free and highlyefficient.Differentkindsof fuelcellsare employedin portablepowersystems, automobiles,andbuildings.Adoptionhas beenconstrained,though,byhigh costs. HydrogenProduction:Nowadays,themajority ofhydrogeniscreatedbysteammethanereforming naturalgas.However,"greenhydrogen" canalsobe createdbyelectrolyzingwatertoseparatethe hydrogenand oxygenusingelectricitygeneratedfrom renewablesources.R&Dis focused onrenewable hydrogen production techniques.

  2. HydrogenStorage:Becausehydrogenisalight,gaseouselement, storing itefficientlyisdifficult. Hydrogencanbecompressedor liquefiedforstorageorbonded withothermaterials.Newstorage methodsareneededtoincreasecapacity and reducecosts. HydrogenTransportation:Hydrogeniscurrently transportedviapipelines,trucks,trains,andships,but in order to support alarger hydrogenenergyeconomy,capacity needsto increase significantly. Investments innewpipelines andinfrastructureareessential. HydrogenRefueling:There are currently onlyafewhydrogenstationsinexistence.An expanded infrastructureforgaseousandliquidhydrogenrefueling isnecessaryforthewidespreadconsumer adoptionof hydrogenfuelcell vehicles.Fueling ismadesimple. In conclusion,major areasofconcentration forhydrogentechnologiesincludelowering thecostof productionandstorage,extending theinfrastructurefordistribution,andenhancingthelongevityand efficiency of fuelcells.By overcomingthesetechnicalobstacles, hydrogen'spotentialasaflexible and clean energysourcecan be realized.
