Et NASA G2 svinghjulsbatteri (Flywheel Energy Storage (FES)). Kan fungere i 15 år pga. friktionsløse magnetiske lejer, som aldrig skal smøres. Kan oplades og aflades 100.000 gange. Ca. 85-95% oplade/aflade effektivitet. Ladningsgraden er let at bestemme, da den kan bestemmes af omdrejningshastigheden.
Bil drevet af en trykluftstank med indbygget kompressor som blot skal tilsluttes stikkontakt.
Modelfly med elastikdreven propel.
Fjeder til urværk og slagværk til at gemme potentiel energi.
Når man på isskøjter har opnået en fart og skøjter ligeud, har man faktisk lagret muskelenergi som kinetisk energi. Grundet den lave friktion med isen og luftmodstanden, taber man kun langsomt fart.
En elektrisk spole fungerer som et kortvarigt energilager i smps.

Energilagring er det at gemme energi i en eller anden form, så den senere kan anvendes.

Fremtidig energilagringsmetode[redigér | redigér wikikode]

I fremtiden kan det tænkes at man kan gemme energien i brint (besværligt at gemme) eller ætanol (ugiftigt, miljøvenligt og let at opbevare).

Launchpoint: Gravity Power Featured in Water Power & Dam Construction Magazine, Gravity Power’s innovative pumped storage hydropower technology, the Gravity Power Module, is the subject of a recent article in International Water Power and Dam Construction (IWPDC) Citat: "...His idea is called the Gravity Power Module (GPM) and, in concept, it is like a sealed water-filled piston...The pipes always remain full of water, including above and below the stack, whether it is stationary or moving..."

Ethanol som energilager: 2004-02-16, ScienceDaily: New Reactor Puts Hydrogen From Renewable Fuels Within Reach Citat: "...The first reactor capable of producing hydrogen from a renewable fuel source – ethanol – efficiently enough to hold economic potential has been invented by University of Minnesota engineers. When coupled with a hydrogen fuel cell, the unit – small enough to hold in your hand – could generate one kilowatt of power, almost enough to supply an average home, the researchers said...if you used ethanol to make hydrogen for a fuel cell, you would get 60 percent efficiency..."
