An Air Force Research Laboratory project demonstrated its mission capability during a power outage at Joint Air and Naval Base Pearl Harbor-Hickam (JBPHH), Hawaii, Dec. 5.

A containerized hydrogen fuel cell back-up power solution commissioned by Hydrogenics Corporation, proved successful when it quickly engaged to replace power to its designated areas during the outage which affected the base for nearly 12 hours.

“The fuel cell system didn’t miss a beat, not even a single hertz,” said Mark Schultz, site manager for HydraFLX Systems, operator of the Hydrogen Station under a cooperative agreement with AFRL’s Advanced Power Technology Office (APTO).

The system was used to enable the continued operation of the Hickam Hydrogen Station, providing for the hydrogen fleet at JBPHH. This real world event proved to be a demonstration of the utility of Hydrogen Fuel Cell technology.

“The Hydrogenics fuel cell systems produced very high quality electrical power all night long – not a flicker, blip, dip or trip all night. No faults, warnings, nor any failures,” added Schultz. “We’re extremely pleased Hydrogenics backed up these proof-of concept trials. Our work resulted in a shining moment for fuel cells going toe-to-toe with our diesel counterparts.”

Hydrogen alternatives reduce the Air Force’s reliance on petroleum fuels for ground based vehicles and equipment through the adoption of alternative, renewable energy sources.

“If this had been a more serious crisis situation such as an earthquake or hurricane, in addition to demonstrating a fully off the grid Hydrogen Refueling Station, we would’ve also been filling the fuel cell vehicles as an emergency response fleet. We had enough fuel to power the station for 10 days and 10,000 road miles of equivalent hydrogen energy to the Fuel Cell Vehicles (FCVs).”

 Hydrogenics fuel cell power modules are currently powering a number of FCVs, including buses that operate around the base.

"Events such as the outage at JBPHH help underscore the capabilities of hydrogen based power generation for critical applications," said Daryl Wilson, Chief Executive Officer of Hydrogenics. "We salute the members of AFRL and HCATT for their forward thinking in applying this technology for the Hydrogen Station at the Joint Base Pearl Harbor-Hickam." The fuel cell system project is an effort under AFRL's Advanced Power Technology Office. The APTO program executes technology development and demonstration of alternative energy technologies on behalf of the Deputy Assistant Secretary of the Air Force, Energy.

Kareem Afzal, Vice President of Business Development, presents Beijing Longradar Technology & Trading Co. Ltd staff Mooncakes for the Chinese celebration of Moon Festival.
The Mid-Autumn Festival is a popular harvest festival celebrated by Chinese and Vietnamese peoples. The festival is held on the 15th day of the eighth month in the Chinese calendar, during a full moon, which is in late September or early October in the Gregorian calendar, close to the autumnal equinox.
The Mid-Autumn Festival is also known by other names, such as:
• Moon Festival, because of the celebration’s association with the full moon on this night, as well as the traditions of moon worship and moon gazing.
• Mooncake Festival, because of the popular tradition of eating mooncakes on this occasion.

Introduction to Diaphragm Compressors

Published on May 15, 2013 by in Blog, News

Diaphragm compressors are the preferred choice when contamination-free and leak-tight gas compression is required. Diaphragm compression achieves its high purity compression by isolating the pulsating hydraulic fluid from the process gas with a set of triple metallic diaphragms and a set of static seals. The reciprocating piston moves a column of high pressure hydraulic oil through a fixed cavity, which allows the diaphragms to compress and pump the process media.

PDC utilizes the latest technology in cavity contour design, diaphragm processing technology and metallurgical design to provide the longest lasting diaphragm life in the industry.

The typical markets for diaphragm compressors include:
• The industrial gases industry including transfilling, cylinder and tube trailer filling stations, and gas distribution markets such as helium, hydrogen, nitrogen, and argon among others.
• The specialty gases industry including electronics gases (silane, specialty gas blends), calibration gases among others.
• The alternative energy sectors including the hydrogen energy sectors, compressed natural gas applications and biogas industries.

PDC leads the industry in diaphragm life and our typical client reports between 6000 and 8000 hours of operating life from PDC machines diaphragms.

Low operating temperatures
Diaphragm compressors are well-suited for applications ranging from vacuum to pressure as high as 60,000 psig [4136 BARG]. Diaphragm compression is very unique in that compression application that could require three to five stages on traditional types of compressors, in diaphragm compressors can be done in one to two stages.

“Diaphragm compression is very unique in that compression application that could require three to five stages on traditional types of compressors can be done in one to two stages”

This is due to heat being dissipated in the mass of the large surface area of the compressor head assembly(s), the presence of pulsing oil and integral cooling of the compressor heads. Typically, diaphragm compression can run 20-60% cooler on outlet temperatures than other types of compression technology. This inherent advantage enables downstream cost benefits including lower operating and maintenance costs. PDC compressors run a compression cycle that is more isentropic than adiabatic and this enables – in certain applications – compression ratios as high as 100:1.

High efficiency and low-power
From an efficiency perspective, diaphragm compressors provide outstanding results.

Due to horizontally opposed crankcase designs, PDC compressors, for example,
can achieve up to 33% brake horsepower reduction in running power, as opposed to traditional in-line opposed designs with high suction pressures.

Volumetric efficiencies run between 87% and 94% depending on the compressor size, and isentropic efficiencies upwards of 90%. This all correlates to maximizing the return on the capex spent with low power requirements and high efficiencies.

Integral hydraulic lube oil system
With all PDC compressors, automatic priming pumps are included as a standard, eliminating the priming problems typically associated with gravity-fed lube oil pumps or hand crank devices. This automatic system works in tandem with an automatic injection pump assembly which injects a fixed volume of oil into the compressor head assemblies during each suction stroke.

This injection pump acts as a compensation pump device, compensating for the following:
• Normal oil leakages past the high pressure oil piston
• Compressibility of the oil under high pressure
• Providing for over-pump to ensure the diaphragm makes a complete sweep of the process cavity, enabling full efficiency during each compression stroke.

Safety features
Standard diaphragm or seal failure leak detection systems are provided on all PDC diaphragm compressors. This interlock stops the compressor upon a failure of either a process or oil side diaphragm or seal.
Due to the inherent nature of diaphragm compressors, there is no possibility of leakage of the process media to the atmosphere, the crankcase or into the hydraulic oil. This enables the compression of pyrophoric, explosive, radioactive and other hazardous gases, without the need to purge crankcases or manage gas leakage past the main seals.
