A small cylinder of hydrogen fluoride with 340 g or 360 liter of HF in it. More than enough to kill someone.   Hydrogen fluoride is a colorless gas what can be liquefied quite easily, with a little ice and water, since its boiling point is 19.5 °C. The gas or its solution in water (hydrofluoric acid) attacks glass, so it could be only stored in steel or plastic.

FC-22-A MQ-2 Combustible Gas Sensor Module for Liquefied Gas / Propane / Hydrogen - Blue + Silver. Model: FC-22-A - Quantity: 1 - Color: Blue + silver - Material: PCB - Sensitive material of MQ-2 gas sensor is SnO2, which is with lower conductivity in clean air. When the target combustible gas exist, The sensors conductivity is more higher along with the gas concentration rising; Please use simple electrocircuit, Convert change of conductivity to correspond output signal of gas…

WHILE politicians and environmentalists are on a collision course over plans to build a coal gasification plant at Hastings, Kawasaki Heavy Industries is already building a test vessel to carry liquefied hydrogen. The ship now being developed by the Japanese company is designed to carry 2500 cubic metres of the gas which will be produced...

KLM's new engine would use two different combustion systems. The first burns either cryogenic hydrogen or liquefied natural gas (LNG), and the second burns either kerosene or biofuel.  "By using two different combustor and fuel systems, the engine's total efficiency increases and emissions are reduced," said Duivis.
