摘要： A method and system of generating electrical power or hydrogen from thermal energy is disclosed. The method includes separating, by a selectively permeable membrane, a first saline solution from a second saline solution, receiving, by the first saline solution and/or the second saline solution, thermal energy from a heat source, and mixing the first saline solution and the second saline solution in a controlled manner, capturing at least some salinity-gradient energy as electrical power as the salinity difference between the first saline solution and the second saline solution decreases. The method further includes transferring, by a heat pump, thermal energy from the first saline solution to the second saline solution, causing the salinity difference between the first saline solution and the second saline solution to increase. The method may include a process of membrane distillation, forward osmosis, evaporation, electrodialysis, and/or salt decomposition for further energy efficiency and power generation.

摘要： The present invention provides a spiral membrane element suitable for suppressing a decrease in a permeation rate (or a permeation flux) of a permeated fluid from a separation membrane. A spiral membrane element of the present invention includes: a central tube; a membrane leaf that has a separation membrane and a permeation spacer and is wound around the central tube; and a flow passage spacer that is connected to the permeation spacer and is wound around the central tube on a side closer to the central tube than the membrane leaf is. A pressure loss of the flow passage spacer measured by a predetermined test is smaller than a pressure loss of the permeation spacer.

摘要： A liquid fuel synthesis system includes a liquid fuel synthesis portion and a sweep gas supply unit. The liquid fuel synthesis portion is partitioned into a non-permeation side space and a permeation side space by the separation membrane. A temperature of the sweep gas flowing into the permeation side space is higher than at least one of a temperature of the raw material gas flowing into the non-permeation side space and a temperature of a first outflow gas flowing out of the non-permeation side space. A temperature of a second outflow gas flowing out of the permeation side space is higher than at least one of the temperature of the raw material gas flowing into the non-permeation side space and the temperature of the first outflow gas flowing out of the non-permeation side space.

摘要： A method for controlling a membrane distillation system includes determining whether there is a day time or a night time at a location of a solar collector system associated with the membrane distillation system; applying a first control mode during the day time to a flow velocity of a feed used by the membrane distillation system; and applying a second control mode, different from the first control scheme, during the night time, to the feed. The first control scheme is a model-free mode.
