Abstract: The present inventions is directed to a sensible heat storage apparatus and use thereof. The apparatus comprises an inner vessel (2) comprising an internal volume (3) adapted to comprise a fluid (4); an outer container (5) enclosing said inner vessel; a thermal insulation layer (6) between said inner vessel and said outer container; and at least two integrated connections (71, 72) to connect the internal volume of said inner vessel to an outer environment through the thermal insulation layer. Said integrated connections are adapted to integrate and accommodate at least two individual sub-connections such that every integrated connection forms a single thermal bridge (8) between the inner vessel and outer container and wherein all thermal bridges are located in the bottom 75% of the total height of said outer container.

Abstract: The invention is directed to a system for energy storage comprising a chemical combustion reactor comprising a reactor segment that comprises at least two porous active fixed beds that are separated by an inactive insulating layer which are at least partially surrounded by an insulating mantle. The active beds comprise a metal and/or oxide thereof.

Abstract: The invention relates to a sensible heat storage apparatus that comprises a core material that can be heated to a high temperature while it has been placed in a heat transfer fluid that absorbs essentially all the heat that is lost by any heat leakages from the core material. Accordingly, there is a very low, or almost absent overall heat loss, even though the sensible heat storage apparatus can store heat at a very high temperature. The gist of the invention is further that the high amount of heat can gradually be transferred to the HTF, which heat can in turn be put to use for domestic applications (e.g. domestic hot water and/or space heating) or for steam generation.

Abstract: In accordance with the present invention there is provided a method for deoxygenation of a first liquid, which method comprises contacting said first liquid with a membrane, which membrane is on its filtrate side in contact with a second liquid comprising an oxygen scavenger. There is provided a second method for deoxygenation of a first liquid which method comprises contacting said first liquid with a membrane, which membrane is on its filtrate side in contact with an oxygen-lean sweep gas. The invention is also directed to an apparatus for carrying out these methods. The present invention provides a very efficient means to deoxygenate liquids of all sorts, such as CO2 scrubbing solutions and beverages.
