The 2.2GW NEOM green hydrogen and ammonia project in Saudi Arabia has completed construction and is currently being commissioned for a start of operations in 2027, according to one of its developers, Acwa.  “The plan is basically commercial operation will be next year,” said Acwa CEO Samir Serhan on a recent earnings call.  He added that construction is “finished”, and that the plant is currently being commissioned to meet the target of beginning operations in 2027.

Once operational, the NEOM green hydrogen and ammonia complex will be the largest by electrolyser capacity in the world, at more than quadruple the size of the current largest project, Envision Energy’s 500MW plant in Chifeng, China.

While Air Products had initially agreed to be the NEOM project’s sole offtaker of green ammonia, the industrial gases giant has since finalised a deal last month with fertiliser firm Yara to sell on volumes that Air Products has not managed to sell on a commission basis.
