Claims (11)

1. Hydraulisk energilager (1) med et første (2) og et andet fluidreservoir (6), hvis fluidniveauer (4, 12) forløber i forskellige højde, som via en turbine-pumpeanordning (10) er forbundet med hinanden, og en fluid (3) kan bevæges frem og tilbage mellem det første (2) og andet fluidreservoir (6) under driften, hvorved der kan omdannes energi, kendetegnet ved, at det andet fluidreservoir (6) er udformet som beholder, som er anbragt i fluiden (3) inde i det første fluidreservoir (2), hvor fluidniveauet (12) i det andet fluidreservoir (6) kan ændres under driften på en sådan måde, at nedsænkningsdybden (ht) af det andet fluidreservoir (6) i det første fluidreservoir (2) kan ændres på grund af opdriften.
2. Hydraulisk energilager (1) ifølge krav 1, hvor fluidniveauet (12) af det andet fluidreservoir (6) ligger under fluidniveauet (4) af det første fluidreservoir (2).
3. Hydraulisk energilager (1) ifølge krav 1 eller 2, hvor det andet fluidreservoir (6) er forsynet med ekstra belastninger (8) for at øge nedsænkningsdybden (ht) og niveauforskellen (h).
4. Hydraulisk energilager (1) ifølge krav 1, 2 eller 3, hvor nedsænkningsdybden (ht) og niveauforskellen (h) øges via en trækindretning (18, 18').
5. Hydraulisk energilager (1) ifølge krav 1 eller 2, hvor det andet fluidreservoir (6) er forsynet med et eller flere opdriftslegemer (9), således at fluidniveauet (12) af det andet fluidreservoir (6) ligger over fluidniveauet (4) af det første fluidreservoir (2).
6. Hydraulisk energilager (1) ifølge et af kravene 1 til 5, hvor fluiden (3) ved fyldning af det andet fluidreservoir (6) deformerer et elastisk element (20, 24) mod en spændekraft.
7. Hydraulisk energilager (1) ifølge krav 6, hvor det elastiske element (20, 24) omfatter en fjederkonstruktion (19, 20) og/eller er udformet som en gasformet buffer (24).
8. Hydraulisk energilager (1) ifølge krav 7, hvor den gasformige buffer er udformet som en luftpude (24), der er anbragt over fluidniveauet (12) af det andet fluidreservoir (6), og det andet fluidreservoir (6) er udformet som en lukket beholder.
9. Hydraulisk energilager (1) ifølge et af de foregående krav, hvor pumpe-turbineindretningen (10) er anbragt i en åbning (11) i bundområdet af det andet fluidlager (6).
10. Hydraulisk energilager (1) ifølge et af de foregående krav, hvor pumpe-turbineindretningen (10) er koblet med en elektrisk maskine, der kan anvendes som elektrisk motor i en pumpedrift og som generator i en turbinedrift og kan forbindes med en elektrisk forbruger og/eller med en elektrisk strømkilde.
11. Storenergilageranlæg med et hydraulisk energilager (1) ifølge et af de foregående krav, hvor det første fluidreservoir (2) er vand, især et hav, sø eller opstemmet sø.
