‘Green’ hydrogen to be converted to ammonia using Haldor Topsoe technology

| By Chemical Engineering

The world’s largest “green” hydrogen project — a $5-billion investment to be located in NEOM, Saudia Arabia — will use Haldor Topsoe’s technology to convert hydrogen  into 3,500 tons per day ( 1.2 million tons 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 existing, well-proven infrastructure.

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 two billion dollars by Air Products.

When implemented, the project avoids all emissions from the equivalent of over 700,000 cars, including over three million tons per year of CO2. “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,” says Amy Hebert, Deputy CEO and EVP, Chemicals, Haldor Topsoe.
