Project name
Green Ammonia – Development of Large-scale Greenfield Ammonia Project. Process Lead Support
Time span
Key figures
o Ammonia production: 100 000 tonnes / year
o PV capacity: 500 MW
o Electrolyser capacity: 320 MW
o Ammonia pipeline: 1500 m
o Liquid ammonia storage capacity: 10 000 m3


Norconsult was engaged by the client as Principle and Lead Process Engineering support during; FEED, due diligence of electrolyser and hydrogen storage sub-suppliers, detail design and engineering, procurement of equipment packages for a complete ammonia plant with supporting systems, warranty- equipment- and liability contract negotiation.


Norconsult support in the FEED phase ensures vendor selection of packages for the complete plant. Currently, as the project is in detail engineering, Norconsult is supporting the project on completion of RAM, HAZID studies, contracts, and procurement related activities.

The whole facility will be mainly driven by solar electricity from a 500 MW AC PV plant. 320 MW of electrolyser capacity will be installed in order to produce enough hydrogen during daytime to enable  

night-time operations of the ammonia plant. The ammonia facility will operate 24/7.


Norconsult has been supporting the client in the process of becoming a large-scale green ammonia supplier.
