Abstract: The invention relates to a process for fueling of vehicle tanks with compressed hydrogen comprising splitting ammonia into hydrogen and nitrogen in an ammonia cracking unit, compressing the hydrogen from the ammonia cracking unit, and dispensing the compressed hydrogen to the vehicle tanks in a hydrogen fueling unit comprising one or more dispensing units, wherein chilled ammonia is used to cool the compressed hydrogen before being dispensed to the vehicle tanks by heat exchange between the compressed hydrogen and the chilled ammonia so that the chilled ammonia is heated, and transferring the heated ammonia to the ammonia cracking unit.

Abstract: A burner apparatus (10) includes a fluid-based flame stabilizer for discharging a stabilized flame therefrom, a burner tile (44), and fuel lances associated with the burner tile. Each of the fuel lances has a discharge nozzle (40). A Coanda feature (34) having a Coanda surface directs a portion of the stabilized flame from the passage defined by the burner tile at the discharge end of a primary flow passage (32) toward at least one first fuel lance of the plurality of fuel lances to cross light the at least one first fuel lance. In another embodiment, a method of combustion includes supplying a first gaseous fuel to fuel lances of a burner apparatus and igniting and sustaining combustion of a gaseous fuel by cross lighting at the discharge nozzles of the fuel lances by flow from the fluid-based flame stabilizer along a Coanda surface of a Coanda feature toward the discharge nozzles.

Abstract: A process and system for a process for releasing hydrogen from a hydrogenated organic carrier. The process including providing a reactor system comprising a first reaction zone and a second reaction zone, the first reaction zone having a first reaction condition and the second reaction zone having a second reaction condition, wherein the first reaction condition and the second reaction condition are different. A ballast system and method are also disclosed. The ballast system includes at least one vessel containing metal hydride capable of selectively storing hydrogen from the hydrogen-containing stream and one or both of selectively providing hydrogen to one or both of a hydrogen load or the dehydrogenation system.

Abstract: A system for monitoring thin-film fabrication processes is herein disclosed. Diffraction of incident light is measured and the results are compared to a predictive model based on at least one idealized or nominal structure. The model and/or the measurement of diffracted incident light may be modified using the output of one or more additional metrology systems.

Abstract: An apparatus and method for storing and releasing hydrogen is disclosed. In one embodiment, the apparatus includes a reactor, a heater having a first portion that is located in the reactor; a dehydrogenation catalyst that is affixed to the first portion of the heater; a hydrogen release conduit in communication with the reactor; a chamber containing a hydrogenated carrier; and an energy source coupled to the heater.

Abstract: An optical system includes both a microspot broadband spectroscopic ellipsometer and a photoacoustic film thickness measurement system that are supplied laser light by the same laser light source. One of the systems makes a measurement, the result of which is used to adjust a parameter of the other system; e.g. the ellipsometer measures thickness and the photoacoustic system uses the thickness result to measure the speed of sound. In one version, the ellipsometer converts the laser beam to a broad-spectrum beam that provides higher intensity.

Abstract: An automated metrology system for photoacoustic measurement of single or multi-layer films, and a method of making the system, are disclosed. Dramatic improvements in the cost of ownership of the system is attained by making the system scalable from a system having a single metrology sub-system for making measurements, to a system having two, vertically stacked metrology sub-systems for making independent measurements. A front end of the system for storing multiple cassettes comprises a robot having vertical travel capable of transferring cassettes to and from each of the first and second metrology sub-systems in the case the system is expanded. The two metrology sub-systems are preferably identical and share much of the optics, a computer as well as the front end of the system. Throughput of the dual system is 1.75-2 times greater than that of a single tool metrology system while the cost is substantially less than two complete single tool metrology systems.
