Haldor Topsoe to supply ammonia tech to world's largest green hydrogen project

A US$5 billion dollar green hydrogen production facility to be sited in NEOM, Saudi Arabia, will include Haldor Topsoe’s proven ammonia technology. The planned green ammonia loop will be the world’s largest on a par with the Gulf Coast Ammonia facility to be built in Texas, United States (US), which will also use Haldor Topsoe's ammonia technology.

The recently announced NEOM project, to produce 650 tonnes per day of carbon-free hydrogen to power buses and trucks around the world, is equally owned by partners Air Products, ACWA Power, and NEOM. Air Products will be the exclusive off-taker of the green ammonia and intends to transport it around the world to be dissociated to produce carbon-free hydrogen for the transportation market.

The NEOM project will use about 4 GW of renewable power from solar, wind, and storage to produce 650 tonnes per day of carbon-free hydrogen. Using Haldor Topsoe’s proven technology, the hydrogen will be converted into 3 500 tonnes per day – or 1.2 million tonnes per year – of green ammonia.

The conversion of hydrogen into ammonia is an innovative approach to facilitate safe and reliable transport and storage of the green fuel, using the existing, well-proven infrastructure.

Ammonia as a hydrogen carrier

Air Products will be the exclusive off-taker of the green ammonia produced at the NEOM site and intends to transport it around the world to be converted back into carbon-free hydrogen at local hydrogen refueling stations.

Air Products’ focus is to supply hydrogen fuel cell buses and trucks with carbon-free hydrogen by 2025. The distribution to end customers represents an additional investment of US$2 billion by Air Products.

We are honored to be part of this innovative world-scale project to reduce carbon emissions. Topsoe is focused on improving energy efficiency in today’s technologies while developing the solutions of the future. This is a great step ahead, said Amy Hebert, Deputy CEO and EVP, Chemicals, Haldor Topsoe.

In May 2020, Haldor Topsoe and Air Products revealed that they had signed a global alliance agreement for collaboration on large-scale ammonia, methanol, and/or dimethyl ether projects around the world.

Based on almost 80 years of experience in ammonia, Haldor Topsoe’s “industry-leading solutions” ensure reliable and safe operation with the lowest possible energy consumption and the lowest possible emissions. From new plants to revamps, its solutions secure optimal operation by increasing capacity, efficiency, and feedstock flexibility.
