Decarbonizing Industrial Processes Beyond Clean Power: Case Study of “Solar Powered Hydrogen” for Ammonia Production
In 2019 Terabase Energy, a California-based company digitalizing the solar power plant, and ANT Energy Solutions, an Australian hydrogen engineering firm, collaborated on a feasibility study for a large scale solar to hydrogen project in Queensland, Australia. This first-of-its kind project aims to produce 24 tons a day of 100% solar-powered hydrogen for Dyno Nobel’s Ammonia Nitrate manufacturing facility.
The scope of the study included 1) determination of the necessary solar generation and hydrogen storage capacity required for the hydrogen plant to operate off-grid year-round, 2) pros and cons of centralized vs. distributed DC collection system, and 3) optimal design and technology options to minimize the plant’s Levelized Cost of Hydrogen. The study concluded that a 220 MWp solar facility, paired with hydrogen electrolyzers, could support the Dyno Nobel Ammonia Nitrate manufacturing facility year-round. The proposed solar and hydrogen facility is now slated for a 2021 COD.
