Fire and Explosion At Hydrogen Station Near Rochester Airport
RossR writes "There was a hydrogen fire and explosion at a renewable fuel station used by government vehicles near Rochester's airport. The nearby freeway and airport were closed resulting in diverted flights. This may the first major incident at a hydrogen vehicle refueling station. GM has their major fuel cell development center nearby, in the town of Honeoye Falls. The fire occurred when the 18-wheeler tractor truck was transferring hydrogen to the station. The airport press conference reported that airport firefighters responded first and initially waited on the scene deciding how to respond. No news yet if the hard to see flames of hydrogen combustion contributed to this delay. The fueling station is also adjacent to a NY State Trooper station, and a firefighting training facility is a few blocks away."
RossR also provides a Police/FD Radio transcript. Luckily, no one was killed, and only two injured, including the driver.
Oh, but hydrogen doesn't explode or even burn! Half a million slashdotters insisted as much, and profusely insisted that the Hindenburg really burned because of a "thermite" or "rocket fuel" skin. ;)
The reality is that hydrogen is an exceedingly flammable gas, much moreso than hydrocarbons, with 1/10th the ignition energy required many times the fuel-air combustible mixture range, and -- unlike hydrocarbons -- readily undergoes deflagration-to-detonation transitions in unconfined spaces. It's also extremely prone to leaks, burns largely clear, and tends to pool in fuel-air mixtures underneath overhangs. To top it all off, it's stored under immense pressure.
