The system may comprise a Proton Exchange Membrane Fuel Cell (PEM FC) stack that is connected to and provides energy to a microgrid for back-up applications, is connected to and provides energy to a fast-charge battery electric vehicle station (BEV) for fast charging of Electric Vehicles (EVs) and is connected to and provides hydrogen to a hydrogen dispenser for fueling Fuel Cell Vehicles (FCVs). Utilizing an integrated forecourt to support several different energy delivery applications and technologies may result in improved overall project economics and may accelerate the transition to a low/zero carbon economy for transportation and stationary back-up power.

Combined hydrogen fuel cell for vehicle fueling, electric vehicle fast charging and fuel cell back-up power forecourt

A hydrogen storage system and method having a main hydrogen storage site that contains a sufficient amount of hydrogen for a fuel cell employing a polymer membrane to generate power in accordance with a predetermined electrical power requirement. A main storage site is provided to store and supply hydrogen to meet the electrical power requirement for the fuel cell. An auxiliary hydrogen storage site contains a sufficient amount of hydrogen to allow the fuel cell to operate on a scheduled basis that is required to maintain the polymer membrane hydrated. A manifold connects the main and auxiliary hydrogen storage sites and has an outlet to deliver hydrogen to the fuel cell. The manifold allows the auxiliary hydrogen storage site to be renewed independently of the main storage site and has a flow control network to allow the fuel cell to draw hydrogen from the auxiliary hydrogen storage site for maintenance purposes without utilization of the hydrogen from the main hydrogen storage site.

A superconducting magnet system wherein a cryocooler provides refrigeration to a cryogenic shield for the superconducting magnet and a heat pipe extends from the cryogenic shield to a cryogen vessel for the provision of supplementary refrigeration.

Superconducting magnet system with supplementary heat pipe refrigeration

A method for operating a cryocooler which provides opportunity for timely intervention prior to failure thus enhancing the reliability of the provision of the refrigeration wherein temperature trending of at least one cryocooler component or the refrigeration load is monitored and used to calculate a service time.

Method for operating a cryocooler using temperature trending monitoring

A pulse tube system for generating refrigeration for uses such as in magnetic resonance imaging systems wherein an oil-free compressor operating at a higher frequency generates pulsing gas which undergoes a frequency reduction and drives the pulse tube system at a more efficient lower frequency.

Low frequency pulse tube system with oil-free drive

A method for operating a cryocooler which provides opportunity for timely intervention prior to failure thus enhancing the reliability of the provision of the refrigeration wherein contaminant concentration downstream of a compressor but upstream of the cryocooler is monitored and the time rate of change of the contaminant concentration is used to calculate a service time.

Method for operating a cryocooler using on line contaminant monitoring

A refrigeration generation system wherein a frequency modulating mechanical resonator is positioned between a pressure wave generator and a cryocooler and serves to reduce the frequency of the oscillating gas emanating from the pressure wave generator so that it more closely comports with a more efficient operating frequency of the cryocooler.

Cryocooler system with frequency modulating mechanical resonator

This invention is directed to a process for recovering helium. The process includes a) passing a first gas containing helium to an eductor to produce a second gas; b) passing the second gas through a heat exchanger to produce a third gas; and c) recovering the third gas into the eductor to combine with the first gas.
