Alfa Laval has signed an agreement to deliver compact heat exchangers to the world’s largest green hydrogen plant, which is to be built in the upcoming city of Neom in Saudia Arabia.
Neom’s location and infrastructure will allow the generation of 4GW of renewable power from solar and wind where the green hydrogen production facility will use about half of it.
It will be the largest green hydrogen plant and the first installation of gigawatt size, producing 650 tonnes of hydrogen per day. This in turn will be used to produce 1.2 million tonnes of green ammonia annually.
When purified water is split into hydrogen and oxygen using renewable electricity, it is crucial to keep a stable temperature in the electrolyser to maximise efficiency. Splitting water into the two gases generates excess heat which needs to be constantly cooled off.
