Abstract: A system may include a datacenter supervisory control system (SCS). A system may include at least one datacenter sensor in data communication with the SCS to communicate a datacenter state variable to the SCS. A system may include at least one environmental sensor in data communication with the SCS to communicate an environmental state variable to the SCS. A system may include a water aware controller in data communication with the SCS, wherein the water aware controller includes a predictor that receives a datacenter state input based on the datacenter state variable, the environmental state input based on the environmental state variable, and at least one user objective function, and the water aware controller transmits a selected action to the SCS to meet a setpoint based on the datacenter state input and the environmental state input.

Abstract: A thermal management system includes an air handling unit (AHU) configured to receive outside air (OA) from an OA intake, and water from a water source, where the AHU is configured to direct conditioned air toward a cold aisle and the AHU includes a modular adiabatic layer containing an evaporative media, and the modular adiabatic layer includes a plurality of subregions configured to be wetted by the evaporative media independently of one another.

Abstract: Examples described in this disclosure relate to waste cold recuperation in fuel cell based power generation systems for datacenters. An example waste cold recuperation system includes a liquefied gas storage for supplying liquefied gas as a coolant to cool a first set of compute resources configurable to operate in a first cryogenic environment. The system is configurable to supply at least some of the vapor phase of the liquefied gas as a coolant to cool a second set of compute resources configurable to operate in a second cryogenic environment, resulting in the at least some of the vapor phase of the liquefied gas becoming a super-heated vapor phase of the liquefied gas. The system is configurable to supply the super-heated vapor phase of the liquefied gas as fuel to fuel cells for providing electrical power to a datacenter load including compute resources configurable to operate in a non-cryogenic environment.

Abstract: A carbon capture system includes two carbon capture plates. A first carbon capture plate collects carbon dioxide from a flow of ambient air. A second carbon capture plate releases carbon dioxide upon application of heat from a heat exchanger. The heat is exhaust heat from a data center. The first carbon capture plate and the second carbon capture plate are rotatable between the capture and release positions. The carbon capture system uses the waste heat from a data center to collect and store atmospheric carbon dioxide, thereby reducing the concentration of atmospheric carbon dioxide.

Abstract: A power controller allocates input power to a datacenter between computing power for computing services, backup power, and overhead power for overhead systems. The power controller reallocates the overhead power and/or the backup power to the computing power. This may increase the overall utilization of the datacenter by allowing additional processing power of the servers to be used.

Abstract: A method of power management in a datacenter includes obtaining at least one workload status of at least one server rack, obtaining at least one infrastructure parameter, obtaining at least one utility telemetry, and comparing the at least one workload status to the at least one utility telemetry. The method further includes determining a workload demand based at least partially on a difference between the at least one workload status and the at least one utility telemetry and changing the at least one infrastructure parameter based on the workload demand and the at least one infrastructure parameter.

Abstract: Cooling a first device and second device in a fashion to produce water. The method includes collecting environmental air from an environment. The environmental air is used to cool a first device. Cooling the first device generates first device exhaust air produced from the environmental air. The first device exhaust air is provided to a first device portion of a heat exchanger. At a second device portion of the heat exchanger, thermally coupled to the first device portion of the heat exchanger, second device exhaust air generated by cooling a second device is received. At the heat exchanger, the first device exhaust air is used to cool the second device exhaust air to a dew point, causing condensed water to be created from the second device exhaust air. The condensed water is collected.
