摘要： Reduction of fuel tank heating during the refueling process is effected by a coolant exchange between the station and the vehicle whereby a heat exchanger internal to the tank is interconnected through a heat exchanger external to the tank with a station side cooler that cools the refill gas to an ambient temperature before introduction into the tank. As a result of station provided ambient temperature cooling, the vehicle does not need to have particularly complicated on-board cooling devices, nor does the station need to be encumbered with complex and expensive pre cooling devices.

摘要： Advantages such as reduced emissions of NOx can be achieved if engines are fuelled with mixtures of gaseous fuels such as hydrogen and natural gas. It is also desirable to store the gaseous fuels separately so that the fuel mixture ratio can be changed responsive to engine operating conditions. However, compared to liquid fuels, a problem with storing gaseous fuels is that they generally require larger storage volumes to hold an equivalent amount of fuel on an energy basis. There are also obstacles to storing some gaseous fuels such as hydrogen in liquefied form because of the energy required to liquefy them and the extremely low temperatures needed to store such gaseous fuels in liquefied form. The invention relates to an apparatus for increasing the storage density of gaseous fuels such as hydrogen by storing them in gaseous form at high pressures and at sub-ambient temperatures. An apparatus is provided for separately storing a first gaseous fuel and a second gaseous fuel. A first vessel defines a first thermally insulated space for holding the first gaseous fuel in a liquefied form. A second thermally insulated space that can hold the second fuel is disposed within the first vessel. The second thermally insulated space is separated from the first thermally insulated space by a thermally conductive fluid barrier. The second gaseous fuel liquefies at a lower temperature than the first gaseous fuel, whereby the second gaseous fuel can be stored within the second thermally insulated space in a gaseous form at a sub-ambient temperature.
摘要翻译：如果使用气体燃料（如氢气和天然气）的混合物来燃烧发动机，则可以实现减少NOx排放的优点。还期望分开地储存气体燃料，使得可以响应于发动机操作条件改变燃料混合比。然而，与液体燃料相比，存储气体燃料的问题在于它们通常需要更大的储存量以在能量基础上保持等量的燃料。由于液化它们所需的能量以及以液化形式存储这种气体燃料所需的极低温度，因此存在一些气态燃料如氢气的液化形式存在障碍。本发明涉及一种用于通过将气体燃料如氢气储存在高压和低于环境温度下的气体燃料来提高其储存密度的装置。提供了用于分别存储第一气体燃料和第二气体燃料的装置。第一容器限定用于将第一气态燃料以液化形式保持的第一绝热空间。可以容纳第二燃料的第二绝热空间设置在第一容器内。第二隔热空间通过导热流体屏障与第一绝热空间分离。第二气体燃料在比第一气态燃料低的温度下液化，由此第二气体燃料可以在亚环境温度下以气态形式储存在第二绝热空间内。

摘要： Systems for handling and/or dispensing hydrogen or a mixture of fuels containing hydrogen gas including refueling stations for hydrogen-powered vehicles. Pure hydrogen or various mixtures ratios of hydrogen and CNG may be dispensed. Hydrogen handling equipment may include a hydrogen generator, a pressurizing apparatus or compressor, pressure vessels, piping, valves, vent pipes, and/or a dispenser. Substantially vertical orientation of pressure vessels may reduce the amount of land required and facilitate installation in urban environments. Pressurization may take place before hydrogen generation to reduce the power required for pressurization. Safety features include enclosures and surrounding walls that lean away from the equipment. Any leaking hydrogen, fires, or explosions may be contained and/or directed upward, protecting human life and property. Systems may be shop assembled and certified.
