SYSTEMS AND METHODS FOR STORING HYDROGEN

摘要

Devices and methods for storing hydrogen fuels or other gaseous fuels (e.g. hydrogen). One embodiment of a container (20) for storing gaseous fuels in accordance with an aspect of the invention comprises a high-pressure vessel (22) configured to contain the gas in a high-pressure zone at a pressure significantly above atmospheric pressure (e.g. 300-10,000 psi). The container (20) can also include a storing medium (40) in the vessel (22) and an inlet/outlet line (50) extending through the vessel (22). The storing medium (40) can have a plurality of storage spaces (28) configured to physically bind molecules of the gas to the storing medium (40), and the inlet/outlet line (50) can be a tube (52) extending through the vessel (22) in fluid communication with the storing medium (40). The molecules of the gaseous fuel bind to the storing medium (40), and the pressure in the vessel drives additional molecules of the fuel into vacant spaces within the storing medium . A heater (60) is used to release hydrogen from the medium (40).
