Abstract:
A pressure vessel refuelling system enables reduced recompression heating in vehicle CNG pressure vessels during refuelling. The system includes a first pressure vessel and a second pressure vessel, each vessel having at least one opening for the entry and exit of a gas and a liquid. A liquid line establishes fluid communication between the first and second pressure vessels via the at least one opening in each of the first and second pressure vessels. A backpressure control device is operatively connected to the liquid line, whereby during refuelling of the first pressure vessel a gaseous fuel from a refuelling station flows into the first pressure vessel, and whereby a liquid in the first pressure vessel flows, under control of the backpressure control device, from the first pressure vessel through the liquid line to maintain a near constant pressure in the first pressure vessel.

Abstract:
A modular energy accumulator system using compressed air. The system comprises a plurality of bladder modules disposed underwater for subjection to a hydrostatic ambient pressure. The plurality of bladder modules include a first bladder module and at least a second bladder module, each of the bladder modules being oriented substantially longitudinally about a vertical axis when made buoyant by ingress of compressed air. An interconnection pipe assembly is configured to facilitate ingress of compressed air into the bladder modules to a pressure level substantially equal to the hydrostatic ambient pressure, and also to facilitate egress of air from the bladder modules at the hydrostatic ambient pressure. The bladder modules are tethered for being maintained in the underwater disposition.

Abstract:
A method and apparatus for transporting LNG are provided. A storage container is disclosed including a support frame fixedly attached to at least one top panel, at least one bottom assembly, and a plurality of corrugated side panels, wherein the support frame is externally disposed around the storage container; wherein the support frame is configured to operably engage at least a portion of a hull of a marine vessel; and wherein the storage container is an enclosed, liquid-tight, self-supporting storage container. A method of manufacturing the storage container is also provided.
Abstract:
Described herein is a portable storage device that stores a hydrogen fuel source. The storage device includes a bladder that contains the hydrogen fuel source and conforms to the volume of the hydrogen fuel source. A housing provides mechanical protection for the bladder. The storage device also includes a connector that interfaces with a mating connector to permit transfer of the fuel source to a device such as a laptop computer. The refillable system comprises a hydrogen fuel source refiller that includes the mating connector and provides the hydrogen fuel source to the storage device. Hot swappable fuel storage systems described herein allow a portable hydrogen fuel source storage device to be removed from a fuel processor or electronics device it provides the hydrogen fuel source to, without shutting down the receiving device or without compromising hydrogen fuel source provision to the receiving device for a limited time.
Abstract:
A flotation device (10) , as shown in figure 1, is provided comprising a carrier (20) mounted to the watercraft (12) with the carrier having a first cover channel (26), a second cover channel (28), a first bladder retaining slot (46), and a second bladder retaining slot (48). A space is defined between the carrier and an elongated cover having a first edge (34) and a second edge (36) with the first edge releasably receivable in the first cover channel and the second edge releasably receivable in the second cover channel. A cover-removing bladder (21) is receivable within the space and secured to the carrier. An inflation mechanism (58) connected to the cover-removing bladder and the flotation bladder inflates both bladders wherein the first edge of the cover is released from the first cover channel of the carrier allowing the flotation bladder to substantially inflate.
