Abstract
Thepurposeofthisstudyhasbeentoincreasetheunderstandingofsomeofthemostcommonlyusedenergystoragetechnologies.Also,theworkaimedtocollectnumericvaluesofanumberofcommonparametersusedtoanalyzeenergystorage.Thesenumericvaluescouldthenbeusedasbasisforafirstevaluationoftheenergystoragetechnologythatisbestsuitedtoagivensituation.
Themethodwasdividedintothreemainphases.ThefirstphasewastogatherinformationonthedifferenttechnologiesandtoassesswhichoftheinformationthatwasrelevanttopresentinatechnicalsurveycalledEnergyStorageTechnologyMapping.Thispartwasdonetoachievethegoalofincreasetheinsightofdifferentenergystoragetechnologies.Thefollowingphasewas,onthebasisofthenumericvaluespresentedinthetechnicalsurvey,todevelopatooltofacilitatethechoiceofenergystoragetechnologiesindifferentsituations.Thefinalphaseconsistedofacasestudythatwasdonetodemonstratethetool’sutilityandevaluateitsperformance.
Withoutcomparingthestudiedtechnologieswithaspecificapplicationinmind,thefollowingwasstatedregardingthefourcategoriesofenergystoragetechnologies:
Electrochemical:highefficiency,shortstorageperiod
Mechanical:largecapacityandpower,highinitialinvestmentcostsandgeographicallylimited
Chemical:verylongstorageperiod,lowefficiency
Thermal:longlifetimeandhighefficiency,variabledependingonthemediumstudied
Fromtheliteraturestudyandtheresultsanumberofconclusionsweredrawn.Amongotherthings,itwaspossibletoconcludethatenvironmental-,social-andethicalaspectsshouldbetakenintoaccountaswellasthegeographical-andgeologicalconditions.Itwasalsopossibletoconcludethatthetechnologiescomparedwerefoundatdifferentstagesintermsofmaturityandcommercialuse,whichwasreflectedintheabilitytofindmoregeneralnumericvaluesrelativetothevalueslinkedtoaspecificapplication.

Beforetheindustrialrevolutionduringthe19thcentury,theneedofenergywasmodestcomparedwithtoday’ssituation.Theenergyneedintheindustrializedworldincreaseinlinewiththetechnologyadvancesmadeduringtheindustrialization.Oneofthemostimportanttechnicalinventionsisthediscoveryofelectricity.Eversinceelectricity,inthe20thcenturybecomeamatterofcourseinmanyindustrializedsocieties;theenergyneedhaveincreasedsignificantly[1].Today,comfortslikehotwater,airconditionerandoutletsprovidedwithelectricityistakenforgranted.Historically,thesourcesconvertingenergyintoelectricity,heatandcoldhavebeenmainlynon-renewable.Fossilfuelssuchasoil,petroleumandnaturalgashavefilledourneedsforalongperiodoftime[1].Productionofheat,coldandelectricityfromthesesourceshavetheabilitytoadapttodemand,hencetheneedofsupplementaryenergystorageislow.However,theseenergysourcesarefiniteandhaveshownnegativeenvironmentalimpact.Apartfromglobalwarming,theincreaseinthedifferentgreenhousegasescontributetooceanacidification,smogpollution,ozonedepletionaswellaschangestoplantgrowthandnutritionlevels[2].
Basedonincreaseddemand,thepriceoffossilfuelshasfirmlyrisenandanumberof“crises”havehadbigeconomicimpact.E.g.thefirstoilcrisisin1973morethandoubledthepriceofoilovernightandledtogreatreactionsworldwide[3].Amongotherthings,Francethenembarkonamajornuclearpowerprogramtoensureitsenergyindependence.Eversince,nuclearpoweraccountedforthebulkoftheelectricityproducedinFrance,correspondingto75%oftheelectricity[4].Asaresultofthedecision,Francehastoday(2016)almostthelowestcostofelectricityinEuropeandishighlyenergyindependent.Also,thecountryhasextremelylowlevelofCO2emissionspercapitafromelectricitygenerationbecauseofthehighproportionofnuclearpower.Nevertheless,nuclearpowerhascausedanumberofseriousaccidentsthathasledtodevastationresultsduetodangerouslyhighconcentrationsofradioactivesubstances[2].NomajoraccidentshaveoccurredinFrancebuttheradionuclidesspreadhasaffectedlargepartsoftheworld,notonlywithintheareawheretheaccidenthappened.
Nuclearaccidentsandglobalwarmingaswellastherisingpriceandlimitedamountoffossilfuelshasincreasedthenumberofdifferentenergysourcesandatthepresenttimetheproportionofrenewableenergysourceshaveincreased[5].Renewableenergysourcessuchassun-andwindpowerarelessharmfultotheenvironmentandinexhaustible.However,theyareunpredictableandmoredifficulttocontrol.Therefore,oneoftoday’slargestchallengesistomatchtheavailableenergywiththeenergydemandintime,placeandquantity[6].Thisappliesnotonlyelectricitybutalsothermalenergyintheformofheatandcold.Forexample,ifitispossibletostoretheenergygeneratedfromthesunduringsunnydaysorsummerseasonstotimeswithlesssunitcanminimizethelossinheatfromproductiontoconsumption.Inthatwayitispossibletousetheresidualheatlateroninsteadofusinge.g.additionalelectricitytogenerateheatfromanelectricalsourceofheatduringtimeswithlesssun.
PresentlythereisagreatnumberofEnergyStorageTechnologies(EST)availableonthemarket,oftendividedintoElectrochemicalEnergyStorage(ECES),MechanicalEnergyStorage(MES),ChemicalEnergyStorage(CES)andThermalEnergyStorage(TES).Allthetechnologieshavecertaindesignandoperationalparametersthatputconstraintstowheneacharesuitabletouse.Allofthetechnologieshavetheiradvantagesanddisadvantagesthereforewhichareidealindifferentsituationsandapplications.Themorematuretechnologiescurrentlyusedarepumpedhydroenergystorage(mechanical),somebatteries
