Article in LA paper March 9, 1999 the-signal.com Got gas? Chernobyl did Valencia firm designs system to check for hydrogen leaks in Leningrad nuclear plant By LEON WORDEN Signal Business Editor Tuesday, March 9, 1999 A nasty buildup of hydrogen gas may not have been the direct cause of the meltdown at Chernobyl, but it certainly didn't help matters when the former Soviet nuclear power plant exploded and spread radiation for miles around. To prevent that sort of disaster in the future, the Russian government has enlisted the aid of Westinghouse to retrofit the Leningrad Nuclear Power Plant with the latest technologies — some of which come from a firm in the Valencia Industrial Center. "Hydrogen is explosive at 4 percent (concentration in air)," said William L. Firestone, Ph.D., president of DCH Technology. "If it reaches 1 percent you might want to know about it." DCH moved to Valencia last year after winning an exclusive license to market new-generation hydrogen-detecting technology developed by researchers at Sandia National Laboratories, where the non-nuclear components of U.S. nuclear weapons are made. Known as the Robust Wide-Range Hydrogen Sensor, the device uses patented palladium-nickel-coated resistors and transistors to "sniff" hydrogen at concentrations under 1 percent and up. It is smaller and faster than its predecessors, and unlike anything previously available for commercial or industrial use, it will survive for an extended period in a nuclear environment — thus the name, "robust." Engineers and technicians at DCH designed the 180-sensor hydrogen gas detection system Westinghouse will use in Leningrad, and more orders could be on the way. "This opens doors (for DCH)," Firestone said. "There are 18 more reactors in Russia and over 300 nuclear plants around the world. This could become a multi-billion dollar business." For now gas detection is at least a $1 billion business annually, and hydrogen gas sensor equipment represents an estimated $107 million of it. The future wasn't always so bright for DCH, which got off to a rocky start five years ago in Sherman Oaks when founders David Haberman and David Walker tried to get into the aircraft temperature sensing business. Product failures led them to recall their early line; they regrouped, brought in experienced technicians and managers from major electronics firms, and found their way to the cutting edge of hydrogen gas detection. In 1996 they landed the Sandia license, in 1997 they went public and in 1998 they moved to larger quarters in Valencia with a 15-person work force. Today the company's chief product, a hand-held hydrogen leak detector, is being field-tested by customers ranging from General Motors to NASA. "We expect this to be our breakthrough year," said Walker, now vice president of business operations. Last week DCH announced that it had signed a multi-year agreement with AlliedSignal, which will integrate DCH technology in missions ranging from nuclear safety to hydrogen powered vessels and corrosion control. DCH is also scheduled to deliver 100 sensors in the first year of a five-year contract with Hydrogen Burner Technology, a Long Beach firm that extracts hydrogen from "dirty gas" for use as a clean-burning fuel. Another new contract puts DCH in the business of measuring deuterium — an isotope of hydrogen sometimes called heavy water — in fiber optic cable; and by the end of the year the company expects to roll out the Universal Gas Detector, a portable device calibrated to measure four different gases at once. An economy model of the hydrogen sensor could go from the drawing board to the living room by the end of the year as well. DCH is developing a hand-held model intended to retail for under $100 for use in the average home or office. It doesn't end there. A few weeks ago DCH built a prototype for a low-wattage fuel cell after securing an exclusive license from Los Alamos National Laboratory. "Hydrogen is the cleanest fuel in the world," Firestone said. "When you burn it all you get is heat, electricity and water. It's the lightest and most plentiful element on earth. Hydrogen is the fuel of the future." Come home to The Signal ©1999, THE SIGNAL · ALL RIGHTS RESERVED.
