  1. This article was very very badly written and is factually incorrect.
    1st incorrect statement: “While the Haber-Bosch process uses huge amounts of energy”, no it does not, the H-B process is (weakly) exothermic, it releases net energy.
    2nd incorrect statement: “The Haber Bosch process requires large amounts of methane gas”. HB uses hydrogen. When first implemented, the HB process used H2 via electrolysis. One of the main suppliers of H2? Step forward Norsk Hydro. Yes the production of H2 requires lots of electricity.
    Currently H2 comes from SMRs (steam methane reformers) which uses methane. The HB process does not and never has directly used CH4 (methane).
    3rd incorrect statement: “rapidly increasing fertiliser costs, due to increasing energy prices and the war in Ukraine”. I will interpret the claim as “increasing gas prices”. Untrue if you consider the USA where Henry Hub prices for nat gas are circa $4/MWh compared to EU TTF prices of Euro40/MWh – somebody is making a load of money from the carry trade (USA – EU and doubtless Gulf States – EU).
    The project looks very promising, it is unfortunate that the journalist was incapable of producing a factually correct article.
