    • There is disclosed an energy storage system. In particular, there is disclosed a chemisorption based energy storage system, able to provide electricity, heating or cooling depending on the desired energy output. The energy storage system includes a first chemical reactor containing a first sorbent material and a second chemical reactor containing a second sorbent material. The first and second chemical reactors are in mutual fluid connection such that a refrigerant fluid can flow from the first chemical reactor to the second chemical reactor, and from the second chemical reactor to the first chemical reactor. The first and second chemical reactors are further provided with means for putting heat in to, or taking heat out of, the first and/or the second chemical reactors. A heat exchanger module is also provided. The heat exchanger module is configured to select from a plurality of available heat sources, a heat source having the highest temperature and an expander module selectively connected to the first chemical reactor and the second chemical reactor via the heat exchanger module. The heat source is arranged to heat the refrigerant fluid prior to the refrigerant fluid passing through the expander module, and the heat exchanger is configured to recover a surplus heat from the highest temperature heat source. The expander module is configured to expand the refrigerant fluid. The means for putting heat in to, or taking heat out of, the first and/or the second chemical reactors provides a flow of refrigerant fluid between the expander module and the first and second chemical reactors, and wherein the expander module is operable to expand the refrigerant fluid to provide a variable work output depending on energy storage requirements.

    • A method for preventing counterfeiting of an object (e.g. paper) is described. The method comprises capturing an image of at least a portion of the object, wherein the portion of the object whose image is captured is at least partially transparent, and wherein the captured image includes features of the internal structure of the object (e.g. the texture of the paper resulting from the arrangement of fibres from which the paper is made). The method further comprises generating, based on the image, a code that encodes features of the internal structure of the object, and recording the code. Generating the code may comprise applying a filter to the image to obtain a filtered image, and processing the filtered image to obtain a binary code. The filter may be a Gabor filter, and processing the filtered image may comprise applying a Gray code to the filtered image. The method may further comprise encrypting the binary code, and recording the code may comprise recording the encrypted binary code. A method for authenticating an object is also described. The method comprises capturing an image of at least a portion of the object, wherein the portion of the object whose image is captured is at least partially transparent, and wherein the captured image includes features of the internal structure of the object. The method further comprises generating, based on the image, a code that encodes features of the internal structure of the object, reading one or more reference values comprising at least a reference code, and authenticating the object based on the code and the reference code.

    • A process for stimulating microbial methane production in a petroleum-bearing subterranean formation, comprising: (a) analyzing one or more components of the formation to determine characteristics of the formation environment; (b) detecting the presence of a microbial consortium, comprising at least one methanogenic microorganism, within the formation; (c) assessing whether the formation microorganisms are currently active; (d) determining whether the microbial consortium comprises one or more methanotrophic microorganism; (e) characterization of one or more microorganisms of the consortium, at least one of the members of the consortium being a methanogenic microorganism, and comparing the members of the consortium with at least one known microorganism having one or more known physiological and ecological characteristics; (f) characterization of one or more methanotrophic microorganisms of the consortium (if present), and comparing the members of the consortium with at least one known microorganism having one or more known physiological and ecological characteristics; (g) using information obtained from steps (a) through (e) for determining an ecological environment that promotes in situ microbial degradation of petroleum and promotes microbial generation of methane by at least one methanogenic microorganism of the consortium; (h) using information obtained from steps (a) and (f), if methanotrophic microorganisms are present, for determining an ecological environment that demotes in situ microbial degradation of methane by at least one methanotrophic microorganism of the consortium; and (i) modifying the formation environment based on the determinations of steps (g) and (h), if methanotrophic microorganisms are present, to stimulate microbial conversion of petroleums to methane while minimising methane destruction by adverse processes.
