Austria published Hydrogen strategy

[kenneal - lagger]

Austria has published a green hydrogen strategy which severely limits hydrogen use to the most essential and efficient uses of the gas. It is about the most sensible proposal that I have seen.

Producing by electrolysis and then using hydrogen in a fuel cell to recover the electricity can be as low as 25% efficient.

Better to use the hydrogen to make ammonia based fertilizer that used to be supplied by the Russians using natural gas. The environment benefits and so do the Ukrainians.

Nitrogen from the air may also be "fixed" and used to manufacture nitrogen fertiliser by means of an electric arc.
The process is very simple but uses a vast amount of electricity, It was largely rendered obsolete by cheap and plentiful natural gas.

This also occurs in nature, lightning produces nitric acid which falls to earth mixed with the rain. This slightly acidic rain then reacts with minerals in the soil and provides a little nitrogen.
