Decarbonising Nitrogen fertiliser production

Posted by – 2010/03/05

Before we had lots of natural gas, nitrogen fertiliser was produced using the Haber-Bosch process. In our low-carbon future, we’ll be making use of it, or something like it, once more. It uses Hydrogen and Nitrogen with energy and an iron catalyst to produce ammonia, which can then form the basis of nitrogen fertilisers. And this process will be of assistance in the move to decarbonise. We can build coastal energy-intensive plants, right on the transmission network, for example at the points where offshore wind farms come ashore, and just operate them when energy is the cheapest. This would help balance demand and supply, at those times when electricity production from wind, wave, tidal and solar energy is highest, and at the same time it helps decarbonise the agriculture sector.
