ABSTRACT

Ignition takes place when the hydrogen gas contacts the catalyst—in prototype burner models, typically a very thin coating of platinum—and the burner begins to give off heat. Conventional atmospheric premix burners suffer from flashback when burning hydrogen. A much greater problem is whether hydrogen can be carried in existing natural gas pipeline networks, something that some researchers took pretty much for granted in the early seventies. The commercial-residential test, completed after the conference, produced generally favorable results for hydrogen. Storage is an essential feature of any gas transmission system to maintain a "buffer" for seasonal, daily, and hourly swings in demand. Cryogenic storage of large amounts of hydrogen is the space-age method. A new storage idea that to some extent minimizes the drawbacks of both cryogenic and hydride storage is adsorption of hydrogen. Hydride storage of hydrogen, in which hydrogen is stored inside the metallic lattice structure of certain alloys such as titanium-iron, has received most attention in automotive applications.
