News from Mitsubishi Hitachi Power Systems
Article

A series of announcements from Mitsubishi Hitachi Power Systems this year shows the breadth of the company’s efforts to prepare for the energy transition. MHPS is a prominent global supplier of large gas turbines for power generation, and is a member of Japan’s Green Ammonia Consortium.

Cardiff University Launches Ammonia Gas Turbine Project
Article

Last week Agustin Valera-Medina, Associate Professor at Cardiff University in the United Kingdom, told Ammonia Energy that work is underway on a £1.9 million (USD $2.3 million) project that will advance the frontiers of ammonia-gas turbine (AGT) technology. Valera-Medina is serving as the Principal Investigator of the Storage of Ammonia for Energy (SAFE) – AGT Pilot, a four-year effort that hopes to develop “a unique, competitive technology that can be implemented to support the hydrogen transition.”

Performance of Ammonia/Natural Gas Co-Fired Gas Turbine with Two-Stage Combustor
Presentation

Ammonia has several advantages as renewable energy career [1-3]. Regarding the manufacturing process, the Harbor-Bosch method is already established. For transportation, ammonia can easily be liquefied at room temperature. Therefore, both transportation and storage are much easier than in case of hydrogen. In utilization, ammonia is combustible and used as a carbon-free fuel. However, ammonia has different combustion characteristics from natural gas. For example, the nitrogen atom contained in ammonia molecule causes high NOx emission through fuel NOx mechanisms [3]. Laminar burning velocity of ammonia is much lower; it might increase unburnt ammonia emission and cause unstable operation of gas…

Pure Ammonia Combustion Micro Gas Turbine System
Presentation

To protect against global warming, a massive influx of renewable energy is expected. Although hydrogen is a renewable media, its storage and transportation in large quantity has some problems. Ammonia fuel, however, is a hydrogen energy carrier and carbon-free fuel, and its storage and transportation technology is already established. In the 1960s, development of ammonia combustion gas turbines was abandoned because combustion efficiency was unacceptably low [1]. Recent demand for hydrogen energy carriers has revived the interest in ammonia as fuel [2, 3]. In 2015, ammonia-combustion gas turbine power generation was reported in Japan using a 50-kW class micro gas…

IHI Corporation pushes its ammonia combustion technologies closer to commercialization
Article

This week, an article in Japan Chemical Daily disclosed IHI Corporation's future plans for its range of ammonia combustion technologies, each of which has been demonstrated in the last year. These include "ammonia-coal co-fired thermal power boilers, ammonia-fired gas turbines and direct ammonia solid oxide fuel cells (SOFCs)." Under the headline "IHI Speeds up Development of Several Ammonia-Based Technologies," the article describes the company's ambitions for scaling-up each of these technologies, and provides a schedule for its next set of demonstration projects.

New Video Summarizes SIP Energy Carriers Accomplishments
Article

ANNOUNCEMENT: The Japanese Government’s Cabinet Office and the Japan Science and Technology Agency have released an English-language video that summarizes the accomplishments of the Cross-Ministerial Strategic Innovation Promotion Program’s Energy Carriers initiative.  The release coincides with the end-of-March conclusion of Energy Carriers’ work, and anticipates this month’s formal activation of the Green Ammonia Consortium.

Performance of Ammonia-Natural Gas Co-Fired Gas Turbine for Power Generation
Presentation

Ammonia is paid special attention as renewable energy carrier [1-3], because it offers advantages in generation, transportation and utilization. Haber-Bosch method is already established as ammonia generation method; large amount of ammonia is already used as fertilizer and chemical raw material. Ammonia can be liquefied at room temperature. Its transport and storage system are already established. Ammonia is cheaper to transport than hydrogen. Ammonia can be used as carbon-free fuel in internal combustion engines as alternative to conventional hydrocarbon fuels. However, it has different combustion characteristics. For example, the nitrogen atom contained in the ammonia molecule, causes high NOx emission…

Two Stage Ammonia Combustion in a Gas Turbine like Combustor for Simultaneous NO and Unburnt Ammonia Reductions
Presentation

Ammonia is expected not only as a hydrogen energy carrier but also as a carbon free fuel. Recently, ammonia fueled gas turbine combustor was successfully demonstrated. However, large amount of NOx was produced when ammonia burns because ammonia includes nitrogen atom in the ammonia molecule. In addition, unburnt ammonia concentration in exhaust gas also needs to be reduced. In this study, we proposed a combustion concept in order to reduce NO and unburnt ammonia concentrations in the exhaust gas simultaneously in a gas turbine like model swirl combustor. In this concept, two stage (rich – lean) combustion was employed. Two…

Development of Low-NOx Combustor of Micro Gas Turbine Firing Ammonia Gas
Presentation

A massive influx of renewable energy is required in order to mitigate global warming. Although hydrogen is a renewable media, its storage and transportation in large quantity is difficult. Ammonia, however, is a hydrogen energy carrier, and its storage and transportation technology is already established. Although ammonia fuel combustion was studied in the 1960s in the USA, the development of an ammonia fuel gas turbine had been abandoned because combustion efficiency was unacceptably low [1]. Recent demand for hydrogen energy carrier revives the usage of ammonia fuel. The National Institute of Advanced Industrial Science and Technology (AIST) in Japan, in…
