Abstract: Process and plant for producing hydrocarbon products from a feedstock originating from a renewable source, where a hydrogen-rich stream and on off-gas stream comprising hydrocarbons is formed. A portion of the hydrogen-rich stream is used as a recycle gas stream in a hydroprocessing stage for the production of said hydrocarbon products, and another portion may be used for hydrogen production, while the off-gas stream is treated to remove its H2S content and used as a recycle gas stream in the hydrogen producing unit, from which the hydrogen produced i.e. make-up hydrogen, is used in the hydroprocessing stage. The invention enables minimizing natural gas consumption in the hydrogen producing unit as well as steam reformer size.

Abstract: Various embodiments may provide non-isolated single-input dual-output (SIDO) bi-directional buck-boost direct current (DC) to DC (DC-DC) converters. Various embodiments may provide a method for controlling a buck duty cycle of the non-isolated SIDO bi-directional buck-boost DC-DC converter such that a first voltage measured across a first portion of the non-isolated SIDO bi-directional buck-boost DC-DC converter is maintained at less than a voltage of a first load and a second voltage measured across a second portion of the non-isolated SIDO bi-directional buck-boost DC-DC converter is maintained at less than a voltage of a second load.

Abstract: A power control device for an electrolyzer that is configured to encode power curtailment information as a DC bus voltage level using a DC droop characteristic in first stage and decode the DC bus voltage to power information in a second stage.

Abstract: A method of operating a fuel cell system which includes a plurality of fuel cells and a plurality of auxiliary components located in at least one cabinet, includes monitoring, by a control unit, a parameter of the fuel cell system, determining whether the parameter has violated a threshold, and varying an auxiliary bus voltage provided to the plurality of auxiliary components connected to a common auxiliary bus by a first amount in response to determining that the parameter has violated the threshold.

Abstract: A system and method for animal feed management for a dairy farm, include a feed management server configured to monitor activities of a plurality of entities in a defined area of the dairy farm by a plurality of sensing devices. The monitored activities include at least a free-style grazing activity by a plurality of dairy animals included in the plurality of entities. An amount of milk yielded by each dairy animal of the plurality of dairy animals is estimated based on the monitored activities. A feed composition for each of the plurality of dairy animals is determined based on the determined amount of milk yielded by corresponding dairy animal and the monitored activities. A loading device, which loads a feed container with the determined feed composition for the first dairy animal, is controlled to manage consumption of the feed composition by the first dairy animal.
