Welcome to European Tribune. It's gone a bit quiet around here these days, but it's still going.

Not so knowledgeable about ammonia as a fuel, but the additional nitrogen molecule will add significantly to the weight of the fuel.

Having worked in the Industrial gas industry for twenty years, I am familiar with the problems of production, handling and storage of hydrogen, and simply put, of all the common gases, hydrogen is the one that gives rise to the most safety issues.

The first liquid H2 plant in Europe was built in the eighties, and as a product, it was a failure,because of the transport/storage problems. The most significant application was for space flight. For the rest, compressed hydrogen worked out just fine.

Compressed is OK.  the first H2 pipeline was built from somewhere in the Ruhr valley to near Köln in the late 20's (article says 30's, believe it's wrong).  It's remained in full use to the present.  notice what's happening now.

"There was a study two or three years ago which calculated that around 300,000 cars could be operated by the excess hydrogen. That is plenty for the short term, we just need to gain access to it. The plan is to build five refuelling stations along the route which are connected to the main pipeline by smaller ones. We have asked Air Liquide to calculate the cost per kilometre of these smaller connecting pipelines so we can get a clearer view of the infrastructure costs," explains Koch.

Another option, he says, is to build filling stations directly at some of the chemical sites along the pipeline. At a plant near Cologne, for example, there is a chlorine electrolyser which can produce hydrogen at very low cost: as low as €2 to €3 per kg, compared to around €12 - €25 per kg at a hydrogen filling station in Berlin.

1  million cubic feet of H2 is about 1/15th of what is used to launch the space shuttle each time.Liquefied, it would fill one 11,000 gal container, which wouldn't run 300,000 cars.

Even 1 miilion cubic feet per day wouldn't be enough as this would work out about 3 cubic feet at atmospheric pressure per car per day.

I'd trust the people behind the NRW project, but not the journalist.
