A power generation process is disclosed, the process comprises dissolving a solute () into an unsaturated stream () to produce a high concentration stream () and converting latent mixing energy present in a high concentration input stream () into power by passage through a power unit () in which the concentration of the high concentration input stream () is reduced. The process comprises using a reduced concentration output stream () derived from the high concentration input stream () following passage through the power unit () as the unsaturated stream (). A first fraction of the high concentration stream () is passed to the power unit () for use as the high concentration input stream () and a second fraction of the high concentration stream () is output from the process.

Solvation entropy engine

A process for solution mining of minerals is disclosed. The process comprises injecting an unsaturated stream () at an injection pressure into a mineral formation () to dissolve the mineral and extracting a high concentration stream () containing said dissolved mineral. The process comprising converting latent osmotic energy present in said high concentration stream into an increase in the total pressure of said stream by passage through an osmotic power unit () and generating electricity and reducing to the injection pressure the total pressure of a reduced concentration output stream () by passage through a power generating device () and using the reduced concentration output stream () at the injection pressure as the unsaturated stream (). A process for storing a fuel in an underground formation is also disclosed.

Osmotic solution mining

A process for generating power from a warm saline steam () obtained from geothermal sources. The process involves converting latent osmotic energy present in the stream () into an increase in the total pressure of said stream by passing through an osmotic pump unit (). The stream is passed over a semi-permeable membrane () and a lower salinity steam () is passed over the other side of said membrane (), such that the need for mechanical pumping in subsequent process steps is reduced.
