We have mentioned the gas turbine program at Tohoku University before (in October 2016 and February 2017). Dr. Aika brought this article to our attention because it provides the full story of the technology development. Hideaki Kobayashi, professor at the Institute of Fluid Science at Tohoku University in Sendai, Japan, has developed the world’s first technology for direct combustion of ammonia in a gas turbine.
The advance was made in cooperation with the National Institute of Advanced Industrial Science and Technology (AIST) under a program led by Norihiko Iki. It has long been known that ammonia is a combustible substance. “We could not supply 100% ammonia in 2014 because we only had a small cylinder (50-kilogram). Mitsubishi Power Developing 100% Ammonia-Capable Gas Turbine. Mitsubishi Power is developing a 40-MW class gas turbine that can directly combust 100% ammonia under an initiative that responds to heightened global decarbonization ambitions, as well as Japan’s recent roadmap for ammonia fuel. The Yokohama–headquartered power equipment firm, a subsidiary of Mitsubishi Heavy Industries (MHI), on March 1 said it is targeting commercialization of the novel ammonia-capable gas turbine, which will be derived from its H-25 series, “in or around” 2025.
“When achieved, it will mark the world’s first commercialized gas turbine to make exclusive use of ammonia as fuel in a system of this scale,” the company said. The gas turbine will “aid in the promotion of decarbonization of small to medium-scale power stations for industrial applications, [and] on remote islands,” it said. Direct Gas Turbine Combustion of Ammonia The development is a notable new direction for Mitsubishi Power. Ammonia Garnering Interest as a Fuel MHI has been notably active on this front.
Ammonia—a renewable fuel made from sun, air, and water—could power the globe without carbon | Science | AAAS. Science and technology of ammonia combustion. This paper focuses on the potential use of ammonia as a carbon-free fuel, and covers recent advances in the development of ammonia combustion technology and its underlying chemistry. Fulfilling the COP21 Paris Agreement requires the de-carbonization of energy generation, through utilization of carbon-neutral and overall carbon-free fuels produced from renewable sources. Hydrogen is one of such fuels, which is a potential energy carrier for reducing greenhouse-gas emissions.
However, its shipment for long distances and storage for long times present challenges. Ammonia on the other hand, comprises 17.8% of hydrogen by mass and can be produced from renewable hydrogen and nitrogen separated from air. Furthermore, thermal properties of ammonia are similar to those of propane in terms of boiling temperature and condensation pressure, making it attractive as a hydrogen and energy carrier. New catalyst turns ammonia into an innovative clean fuel.

Taking measures against climate change and converting into societies that use significant amounts of renewable energy for power are two of the most important issues common to developed countries today.
One promising technology in those efforts uses hydrogen (H2) as a renewable energy source. Although it is a primary candidate for clean secondary energy, large amounts of H2 must be converted into liquid form, which is a difficult process, for easier storage and transportation. Among the possible forms of liquid H2, ammonia (NH3) is a promising carrier because it has high H2 density, is easily liquefied, and can be produced on a large-scale.
Additionally, NH3 has been drawing attention recently as a carbon-free alternative fuel. NH3 is a combustible gas that can be widely used in thermal power generation and industrial furnaces as an alternative to gasoline and light oil.
