osmotic power; salinity gradient power
Technical term in electricity and energy engineering for power generated from the difference in salt concentration between two liquids, typically seawater and freshwater.
Salinity gradient power is a renewable energy technology that uses the difference in salt concentration between seawater and freshwater.
浸透圧発電 is a specific type of osmotic power generation using pressure-retarded osmosis, while 塩分濃度差発電 is a broader term covering all salinity gradient power methods.
Compound of 塩分 (salt content), 濃度 (concentration), 差 (difference), and 発電 (power generation). A modern technical term with no historical derivation beyond its components.
