The U.S. Department of Energy (DOE) is proposing to provide federal funding to the University of California at Los Angeles (UCLA) to investigate and develop reversible ammonia dissociation reactions as a thermochemical energy storage mechanism for solar thermal power.

Activities associated with the proposed project would include design, fabrication and lab-testing of an ammonia synthesis reactor that is optimized for the direct production of supercritical steam and investigation and analysis of drilled wells, converted gas wells, and other types of engineered underground storage in order to identify the optimal storage system for large amounts of energy-rich mixtures of hydrogen and nitrogen. These activities would be completed at the Boiling Heat Transfer Lab on campus at UCLA in Los Angeles, CA. This facility was designed for this type of research; therefore, no new construction, modifications or new permits, additional licenses and/or authorizations would be required and no significant impacts to the environment are expected as a result of the proposed project.
