Pure Ammonia Combustion Micro Gas Turbine System

Ryan Miller November 12, 2019

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…

JGC Corporation demonstrates "world's first" carbon-free ammonia energy cycle

Ryan Miller January 04, 2019

In late 2018, JGC Corporation issued a press release to celebrate a "world's first" in ammonia energy, demonstrating at its pilot plant in Koriyama both "synthesis of ammonia with hydrogen produced through the electrolysis of water by renewable energy, and

Demonstration of CO2-Free Ammonia Synthesis Using Renewable Energy-Generated Hydrogen

Ryan Miller October 31, 2018

In Japan, the government funding project SIP, Strategic Innovation Promotion Program, supports the research, development and demonstration of “Energy Carriers”. The concept of the “Energy Carriers” value chain is to produce hydrogen energy carriers overseas from fossil resources using CCS or renewable energy, and transport it to Japan for utilization as clean energy. The purpose of the program is to help realize a low-carbon society in Japan by using hydrogen. Among energy carriers, ammonia is the one of the most promising carriers, because of the ease of transportation as a liquid, higher hydrogen density, and proven technologies for commercial and…

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

Ryan Miller October 31, 2018

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…

Green ammonia demonstration plants now operational, in Oxford and Fukushima

Ryan Miller June 29, 2018

Two new pilot projects for producing "green ammonia" from renewable electricity are now up and running and successfully producing ammonia. In April 2018, the Ammonia Manufacturing Pilot Plant for Renewable Energy started up at the Fukushima Renewable Energy Institute - AIST

Combustion Emissions from NH3 Fuel Gas Turbine Power Generation Demonstrated

Ryan Miller November 1, 2017

To protect against global warming, a massive influx of renewable energy is expected. Although H2 is a renewable media, its storage and transportation in large quantity is difficult. NH3 fuel, however, is an H2 energy carrier and carbon-free fuel, and its storage and transportation technology is already established. Although NH3 fuel combustion was studied in the 1960s in the USA, the development of an NH3 fuel gas turbine had been abandoned because combustion efficiency was unacceptably low [1]. Recent demand for H2 energy carrier revives the usage of NH3 fuel, but no one has attempted an actual design setup for…

SIP "Energy Carriers" video: ammonia turbines, industrial furnaces, fuel cells

Ryan Miller October 13, 2017

To demonstrate the progress of the SIP "Energy Carriers" program, the Japan Science and Technology Agency last week released a video, embedded below, that shows three of its ammonia fuel research and development projects in operation. R&D is often an abstract

Ammonia Turbine Power Generation with Reduced NOx

Ryan Miller October 06, 2016

A common concern with ammonia fuel is that NOx emissions will be too high to control. However, in new research from Turkey, USA, and Japan, presented at this year's NH3 Fuel Conference in September 2016, two things became clear. First, NOx

Power Generation and Flame Visualization of Micro Gas Turbine Firing Ammonia or Ammonia-Methane Mixture

Ryan Miller September 19, 2016

A demonstration test with the aim to show the potential of ammonia-fired power plant is planned using a micro gas turbine. 50kW class turbine system firing kerosene is selected as a base model. A standard combustor is replaced to a prototype combustor which enables a bi-fuel supply of kerosene and ammonia gas. Diffusion combustion is employed to the prototype combustor due to its flame stability. 44kW power generation was achieved by 100% heat from ammonia gas. Although NOx concentration in the exhaust gas of ammonia combustion exceeded 500ppm, NOx removal equipment reduced NOx concentration below 10ppm. Over 30kW power generation…

Micro Gas Turbine Operation with Kerosene and Ammonia

Ryan Miller September 22, 2014

A demonstration test with the aim to show the potential of ammonia-fired power plant is planned using a micro gas turbine. 50kW class turbine system firing kerosene is selected as a base model. A standard combustor is replaced with a prototype combustor which enables a bi-fuel supply of kerosene and ammonia gas. Diffusion combustion is employed to the prototype combustor due to its flame stability. Demonstration test of co-firing of kerosene and ammonia gas was achieved to check the functionality of the each component of the micro gas turbine. The gas turbine started firing kerosene and increased its electric power…
