Patent number: 11231020Abstract: A process for generating power from a warm saline steam (1) obtained from geothermal sources. The process involves extracting a warm saline stream (1) from an underground geothermal formation (2), reducing the temperature of the saline stream (1) by passing the stream through a thermal power unit (5) in which thermal energy present in the stream is extracted. The process also involves converting latent osmotic energy present in the stream into electricity by passing the stream through an osmotic power unit (7) comprising a semi-permeable membrane (8). The output stream (13) derived from passage through the osmotic power unit is injected into a second, different underground formation.Type: GrantFiled: July 11, 2018Date of Patent: January 25, 2022Assignee: SALTKRAFT APSInventor: Steen Søndergaard Nissen

Patent number: 11231021Abstract: A process for generating power from a warm saline steam (1) obtained from geothermal sources. The process involves converting latent osmotic energy present in the stream (1) into an increase in the total pressure of said stream by passing through an osmotic pump unit (7). The stream is passed over a semi-permeable membrane (8) and a lower salinity steam (14) is passed over the other side of said membrane (8), such that the need for mechanical pumping in subsequent process steps is reduced.Type: GrantFiled: July 11, 2018Date of Patent: January 25, 2022Assignee: SALTKRAFT APSInventors: Henrik Tækker Madsen, Steen Søndergaard Nissen

Patent number: 11231019Abstract: An electricity generation process is disclosed. The process comprises injecting an aqueous feed stream into a salt formation to dissolve the salt contained therein, and then extracting a saline stream containing said dissolved salt from the salt formation. The process also comprises converting latent osmotic energy present in said saline stream into electricity by passage through an osmotic power unit comprising a semi-permeable membrane which permits the passage of water but not the passage of salts in which said saline stream is passed over one side of the semi-permeable membrane, a low salinity stream being passed over the other side of said membrane. The process also comprises using an output stream derived from the low salinity stream as the aqueous feed stream.Type: GrantFiled: March 2, 2017Date of Patent: January 25, 2022Assignee: APPLIED BIOMIMETIC A/SInventor: Steen Søndergaard Nissen

Patent number: 10968128Abstract: A process for the generation of power is disclosed. The process comprises receiving a wastewater stream containing organic matter and passing the wastewater stream to an anaerobic digester in which the organic matter contained therein is broken down to produce biogas. The liquid content of said wastewater stream is reduced before said stream enters the anaerobic digester by passing the wastewater stream through an osmotic power unit. The said stream is passed over one side of a semi-permeable membrane which permits the passage of water but not the passage of salts, an aqueous stream of higher salinity than said wastewater stream being passed over the other side of said membrane such that latent osmotic energy present in said aqueous stream of higher salinity is converted into electricity.Type: GrantFiled: March 2, 2017Date of Patent: April 6, 2021Assignee: APPLIED BIOMIMETIC A/SInventor: Steen Søndergaard Nissen
