Ammonia’s high hydrogen density makes it a very promising green energy storage and carrier medium. In fact, among practical fuels, ammonia has the highest hydrogen density including hydrogen itself both in the cryogenic and also in the compressed gas storage modes. Unlike many other practical fuels, ammonia (NH3) molecule is free of carbon atoms, which leads to zero CO2 emissions during its combustion. The fact that ammonia is already a widely produced and used commodity with well established distribution and handling procedures would allow for its smooth transition as an alternative fuel. The two major disadvantages of the ammonia fuel: 1) low energy density compared to hydrocarbons and 2) toxicity, have hindered its development as a transportation system fuel. Note that both of these issues are not key drivers in power generation systems, making this mode an ideal entry point for the ammonia fuel. SPG Inc. has been developing technologies to burn ammonia in the gas turbine systems with the primary objective of minimizing the NOx and NH3 emissions. The first phase of the project involves establishing the fundamentals of ammonia combustion in gas turbine combustors. As an important part of this phase, testing with ammonia fuel in a simulated gas turbine combustor has already been started.
