A heat management system (100) for minimising overall energy use in a process, in which the heat management system is operable in a first mode for chilling milk (600) or another product and recovering heat therefrom, and a second mode for transferring recovered heat through the system comprising: a refrigeration system (500) for chilling the milk or product, the refrigeration system comprising a refrigeration circuit (550) for receiving a working fluid, including a compressor (554), an evaporator (552), an expansion valve (558), a condenser (556); and a heat recovery system (10) for recovering heat from the milk or product, the heat recovery system comprising first and second heat reservoirs (12, 14), in which during operation in the first mode, the refrigeration system is configured to cool the milk and at least some of the recovered heat is stored in the first heat reservoir, and in which during operation in the second mode, the first heat reservoir is configured to provide heat to the evaporator, and the second heat reservoir is configured to receive heat from the condenser for subsequent use in the process.

A system for dispatching and navigating an unmanned aerial vehicle (UAV) to a target location comprises a UAV and a navigation module comprising a processor and a memory storing a 3D map comprising the target location and machine-readable instructions such that, when executed by the navigation module processor, cause the processor to perform a method comprising identifying a location of the UAV with respect to the 3D map, receiving a target location input, identifying the target location with respect to the 3D map, generating at least one potential route connecting the location of the UAV and the target location, assigning to at least one potential route an evaluation score according to at least one route assessment criterion, selecting the potential route having the highest evaluation score as a preferred route, and transmitting the preferred route to the UAV.

A storage system (100) is provided that includes a primary container (102), a first insulation layer (104), a secondary container (106), a secondary bottom (108), and a second insulation layer (110). The primary container (102) has a primary bottom (112). The first insulation layer (104) is disposed below the primary bottom (112). The secondary bottom (108) is disposed below the first insulation layer (104) and the secondary container (106). The secondary bottom (108) has an expansion joint (114) configured to permit the secondary bottom (108) to expand and/or contract independently from the secondary container (106). The second insulation layer (110) is disposed below the secondary bottom (108). In the event of LNG leaking from the primary container (102), the second insulation layer (110) is protected from LNG contact by the secondary bottom (108). The carbon steel liner (116) located on the outside face (117) of the concrete wall (118) remains vapor tight and liquid tight in the event of any amount of LNG leaking from the primary container (102).
