EETF: Solid State Ammonia Synthesis

Project Overview

This project is designed to use electricity, water, and air to produce ammonia which could be stored and later used to produce electricity. The first testbed for this project will be based in Juneau in the University of Alaska Southeast, Technical Education Center(TEC). The ammonia plant will be connected to the Alaska Electric Light & Power grid through the TEC's internal electricity system. The production of ammonia and the storage of the gas is beneficial because it allows the energy to be stored for a long amount of time, as well as the added advantage of being able to use the gas for other purposes outside of energy production. The gas produced by the plant can be transported via carbon steel pipelines, tanks, barges, and tanker ships. These tanks are identical to the ones used to store propane, however the brass fittings will need to be replaced with steel ones. Current generators can run off of ammonia after being modified however, even then the ammonia needs to be mixed with propane in order for the motor to run for extended periods of time.


Project Objectives

The primary objective of this project is to affirm the feasibility of this project. A potential success would be defined as a complete, self-contained, containerized, transportable plug-and-play systemcapable of round-trip NH3 synthesis, storage, and regeneration of electric energy for feedback into the energy grid.


Technology

Ammonia can be synthesized using electricity, water, and atmospheric nitrogen(N2). This synthesis process is rather inefficient process however if ammonia from oil or gas is used it must be heavily taxed due to the carbon emissions of collecting the ammonia from the oil and gas deposit. In order to obtain energy from the ammonia gas it must be combusted with oxygen to produce useable energy.


Administration of Funds
