4.1.2. Multiweight The energy storage capacity of a gravity energy storage system can be scaled up and optimized by using multiple weights.
Gravity energy storage systems, using weights lifted and lowered by electric winches to store energy, have great potential to deliver valuable energy storage services to enable this transformation.
Some of the aforementioned researches includes pumped hydro gravity storage system, Compressed air gravity storage system, suspended weight in abandoned mine shaft, dynamic modelling of gravity energy storage coupled with a PV energy plant and deep ocean gravity energy storage.

Techno-economic analysis of gravity energy storage. Energetic performance of Gravity Energy Storage (GES) with a wire rope hoisting system. GES and GESH offer interesting economic advantages for the provision of energy arbitrage service.
In simple terms a gravity energy storage device uses an electric lifting system to raise one or more weights a vertical distance thereby transferring electrical energy to be stored as gravitational potential energy.
A watt is defined as 1 joule per second and is therefore a measurement of energy transfer over a period of time.. A kilowatt-hour is a measurement of energy equal to one kilowatt sustained over a period of one hour.. What is the point in double counting units per time? It seems to me that a kilowatt-hour could be more simply expressed as 3.6 megajoules.

Prisen per kWh du betaler i Norge er basert på prisene på den nordiske kraftbørsen Nord Pool. Strømprisene er konstant i endring og endrer seg hvert minutt. I skrivende stund ligger strømprisen på 115,08 øre/kWh i de tre nederste strømsonene. I Midt Norge ligger den på 17,79 og i Nord Norge ligger den på 14,23 øre/kWh.
kWh er symbolet for kilowattime, som er en mye brukt målenhet for energi. 1 kWh er den energien som en effekt på 1 kW utvikler i løpet av en time. Kilowattime er sammensatt av kilo, watt og time. Watt er enheten for effekt i SI-systemet, mens kilo er et prefiks som betyr at enheten skal multipliseres med 1000.
