Synthesis and Assessment of Process Systems for Production of Ammonia Using Nitric Oxide in Combustion Exhaust Gas

Ryan Miller November 14, 2019

Recently, ammonia is regarded as an alternative fuel without carbon dioxide (CO2). Numerous studies have been performed using ammonia as a fuel. Iki and Kurata confirmed the working of a prototype for the ammonia gas turbine, where ammonia burned in an environmentally benign way to generate electricity, exhausting only water and nitrogen [1]. From the view of cycle of ammonia for the development of a society with low carbon, it is required to synthesize carbon-free ammonia (green ammonia) in small plants. This green ammonia can be synthesized using renewable energy, with hydrogen from electrolysis of water and nitrogen from pressure…

Effect of Preparation Condition on Ammonia Synthesis over Ru/CeO

Ryan Miller November 14, 2019

Development of the hydrogen carrier system is of great interest to utilization of renewable energy. To store renewable energy, especially for the electricity from photovoltaic and wind turbine, fluctuation of the generated electricity is not appropriate for the stable supply of the electric power. Also, the hydrogen production by the water electrolysis with the fluctuating electricity results in the fluctuation of hydrogen production. When we store the hydrogen derived from renewable energy in the carrier compounds, it is necessary to consider the reduction or smoothing of fluctuation in the hydrogen flow rate as a feed of chemical process. Although the…

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…

Demonstration and Optimization of Green Ammonia Production Operation Responding to Fluctuating Hydrogen Production from Renewable Energy

Ryan Miller November 12, 2019

Ammonia is a promising hydrogen carrier to transport green hydrogen from overseas to Japan at lower cost and resulting in lower lifecycle CO2 emission. Low carbon ammonia will be produced by fossil fuel reforming with CCS or EOR at the early stage of the introduction of ammonia fuel to the market. Green ammonia production from renewable sources is the ultimate goal, but there are some issues to commercialize. The low capacity factor, which is caused by the fluctuation of solar irradiation or wind speed, is a big issue which leads to ammonia production costs. In this presentation, we would like…

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…

Analysis of influence of operating pressure on dynamic behavior of ammonia production over ruthenium catalyst under high pressure condition

Ryan Miller October 31, 2018

Process technologies on energy conversion of renewable electricity into hydrogen energy carrier are significant to deploy long-term storage and long-distance transport of much more renewable inside and outside Japan. Ammonia is a potential hydrogen carrier that contains 17.6 wt% of hydrogen. Moreover, as an energy carrier, ammonia is thought to be a clean fuel as only water and nitrogen are produced on direct combustion. Many researchers and engineers consider that ammonia plants using hydrogen produced by solar electricity or wind electricity will be much smaller than those currently used [1]. There is an issue of low pressure condition for feed…

Influence of H2 / N2 Ratio on Dynamic Behavior of Ammonia Production on Ru Catalyst Under Low Pressure Condition

Ryan Miller November 2, 2017

Recently deployment of renewable energy such as sunlight and wind power or deployment of process technologies for carbon dioxide capture and storage (CCS) is indispensable to reduce the CO2-emission. However, there are some issues to be solved in order to accelerate the mass deployment of renewable energy. Since amount of renewable energy quite changes unstably with time, which depends on weather and place, development of process systems technology is an issue for stable and effective utilization of electric power that is generated by fluctuating renewable energy. Those in national institute of National Institute of Advanced Industrial Science and Technology (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…

Combustion characteristics of ammonia/air flames for a model swirl burner and an actual gas turbine combustor

Ryan Miller September 19, 2016

Ammonia is expected not only as hydrogen energy carrier but also as carbon free fuel. For an industrial use of ammonia combustor, ammonia flame stabilized on a swirl combustor should be clarified. However, in order to realize an ammonia-fueled combustor, there are some issues to be solved, such as a difficulty of flame stabilization and reductions of NOx and ammonia emission. In this study, stabilization and emission characteristics of ammonia / air flames stabilized by a model swirl burner are investigated. The outer and inner diameters of the swirler are 24 mm and 14 mm, respectively, and the swirl number…
