ABSTRACT

There are severe issues on increasing amount of carbon dioxide (CO2) emission in the world. Many studies are devoted on alternative fuels. One of superior candidates is the utilization of hydrogen energy which can realize a low-carbon and hydrogen-based society. Ammonia might play an important role which is zero emission of CO2, and is useful for hydrogen energy carrier as a clean energy. Additionally, ammonia is an easily-liquefiable fuel with pressure of about 0.86 MPa and temperature of 293 K. Commercially, ammonia is produced in large quantity by the Haber–Bosch process. It is also to be produced by using catalyst with renewable energy sources, such as wind energy and solar energy. Continue reading →

AIChE Annual Meeting, Topical Conference: NH3 Energy+

ABSTRACT

Ammonia is a carbon-free fuel, so it has potential to reduce carbon dioxide emission from power plants when used as a fuel. However, combustion characteristics of ammonia are notably different from hydrocarbon fuels, especially regarding NOx emission [1]. The nitrogen atom of the ammonia molecule may cause high NOx emission. Therefore, special techniques to reduce NOx emission are essential for gas turbine combustors which burn ammonia and natural gas. The results of our previous study [2] showed the characteristics of NOx emission in single-stage combustion. In this study, the concept for low-emission combustion in two-stage combustion has been examined numerically and experimentally. Continue reading →

NH3 Fuel Conference 2017, Minneapolis, November 1, 2017
AIChE Annual Meeting, Topical Conference: NH3 Energy+

ABSTRACT

Unlike some technology areas where “all of the above” has significant advantages, there are tremendous advantages associated with choosing a single, optimized, liquid transportation fuel. The cost, efficiency and environmental benefits associated with choosing an optimized liquid transportation fuel are enormous and merit serious consideration.

NH3 most closely meets the criteria for an ideal liquid transportation fuel. Continue reading →

NH3 Fuel Conference, Los Angeles, September 19, 2016

ABSTRACT

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. Continue reading →

NH3 Fuel Conference, Los Angeles, September 19, 2016

ABSTRACT

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. Continue reading →

ABSTRACT

NH3 is a carbon-free fuel, so it has the potential to reduce CO2 emission from the power plant when used as a fuel. However, NH3 has combustion characteristics different from conventional hydrocarbon fuels. The N atom in the ammonia molecule causes high NOx emission through combustion reactions. To develop a gas-turbine combustor, which burns a combination of NH3 and natural gas with controlled emissions, combustion characteristics have been studied experimentally and numerically by using a swirl-burner, which is typically used in gas-turbines.

ABSTRACT

Based on its well-known merits, ammonia has been gaining special attention as a potential renewable energy carrier which can be replaced in power generation units. One of the major challenges with ammonia as a fuel is NOx emission, which has a complex underlying chemical kinetics. Continue reading →

CONFERENCE HOST 2016

The UCLA Sustainable Technology & Policy Program (UCLA-STPP) serves as the host of the 2016 NH3 Fuel Conference.

Eddie Sturman, Sturman Industries, USA

13th Annual NH3 Fuel Conference, September 20, 2016

ABSTRACT

UCLA-STPP is an interdisciplinary science / policy research unit, enjoining faculty in schools of engineering, public health, law, business, and medicine. The two-part mission of UCLA-STPP is to: (1) evaluate the viability of safer, cleaner, greener, more sustainable substitutes for existing hazardous services, processes, systems, and/or technologies, and (2) employ diffusion analysis to identify institutional, policy, and regulatory barriers to the adoption of viable safer substitutes and prescribe policy changes to overcome key barriers. UCLA-STPP has taken leadership in developing and institutionalizing “alternatives analysis” as policy/regulatory tool as a method to evaluate and identify safer, cleaner, greener, more sustainable substitutes.

UCLA-STPP is employing this alternatives analysis approach to evaluate the commercial viability of using renewable-based NH3 for peak power generation and natural gas for base load power in a camless engine genset system to be installed at a distributed generation pilot demonstration facility in the greater Los Angeles region.
