Ammonia’s Green Power Revolution : Project ARENHA

Focuses on the full power-to-ammonia-to-usage value chain; consortium consists of 11 partners from seven countries

The Advanced Research on Energy Storage and Hydrogen Applications (ARENHA) project aims to demonstrate the feasibility of ammonia as a dispatchable form of large-scale energy storage.

The main technical objectives of the ARENHA project are:
