  24. Saltkraft Prinsippet ved saltkraftverk kalles trykkretardert osmose (TRO) og går ut på å utnytte energien som frigjøres når salt og ferskvann blandes. Dette skjer ved at de tilføres i hvert sitt kammer i et kar adskilt av en membran (se fig). Membranen tillater gjennomstrømning av ferskvann, men ikke saltvann. Det ferske vannet vil da strømme gjennom til den andre siden, og energien i denne strømmen kan tappes ved hjelp av en turbin. Det er det osmotiske trykket mellom ferskvann og saltvann som sørger for at det opprettholdes en strømning gjennom membranen. Det osmotiske trykket er maksimalt 27 bar. Norges energi potensial er 50 TWh Kilde: www.sintef.no
