High Efficiency Electrochemical Synthesis of Ammonia from Nitrogen at Ambient Temperature and Pressure

Greg ReddenFengling ZhouLuis AzofraMuataz AliMega KarAlexandr SimonovCiaran McDonnellChenghua SunAngeline BartholomeuszXinyi ZhangDouglas MacFarlane

Ammonia as well as being an important fertiliser is being increasingly considered as an easily transported carrier of hydrogen energy. However, the traditional Haber-Bosch process for the production of ammonia from atmospheric nitrogen and fossil fuels is a high temperature and pressure process that is energy intensive. Newer technology is being investigated to produce sustainable ammonia from green energy. An ambient temperature, electrochemical synthesis of ammonia is an attractive alternative approach, but has, to date, not been achieved at high efficiency. Researchers from Monash University have obtained faradaic efficiency as high as 60% using liquid salt electrolytes under ambient conditions,…

Introducing the Global NH3 Fuel Federation

Stephen H. Crolius

Until recently, ammonia fuel was the focus of a few dozen individuals working in isolated groups. Institutional interest and support were limited at best. Now we are in a new stage: ammonia fuel is being investigated seriously in publicly and privately supported programs in most of the world’s leading economies. The NH3 Fuel Association has been engaged in informal conversations over the last year about how to respond to this very significant trend. The conclusion is that it is time to launch an initiative that can engender a higher level of mutual awareness, communication, and support across all of the…

Key Life Cycle Assessment Numbers for NH3, Green and Brown Energy

Key Life Cycle Assessment Numbers for NH3, Green and Brown Energy

Yusuf BicerIbrahim DincerCalin ZamfirescuGreg VezinaFrank Raso

This talk will present the results of two recent studies. In the first study, four different ammonia production methods are comparatively evaluated using life cycle assessment (LCA). The proposed ammonia production systems consist of an electrolyzer for hydrogen production and a Haber-Bosch plant for ammonia synthesis. The required energy for the systems are utilized from various resources namely hydropower, nuclear, biomass and municipal waste. Life cycle assessment methodology is used to identify and quantify environmental impacts in global warming potential, human toxicity and abiotic depletion categories of each method during the life cycle of the systems. The proposed non-conventional ammonia…

The Investment Case for Sustainable Ammonia Synthesis Technologies

The Investment Case for Sustainable Ammonia Synthesis Technologies

Trevor Brown

For 100 years, we have made ammonia with the Haber-Bosch process, almost always using a fossil fuel feedstock. Recently, though, government policy, academic innovation, commercial opportunity, and human morality have combined to spur the development of new, “green” ammonia manufacturing processes: sustainable, low-carbon technologies. These new synthesis methods augur a future in which, instead of the single, over-riding drive toward the economies of scale associated with Haber-Bosch, an array of different feedstocks, uses, and business models will support a multiplicity of competing technologies serving multiple markets. This presentation aims to introduce the factors affecting the appetite for commercialization and adoption…

Ammonia as a Key to Meeting the Fuel Demand of China

Ammonia as a Key to Meeting the Fuel Demand of China

Zhaolin (Forest) Wang

Currently, China is facing a challenge of increasing its energy consumption and simultaneously decreasing its emissions. Particularly, the desire of owning a car is so strong in China that it cannot be easily mitigated by high pricing or taxing. This paper presents the statistical results of fuel consumption in China and predicts the fuel demand in near future, it then compares the fuel demand of China with the fuel production scale of the world. It is concluded that China must utilize clean alternative fuels to meet the fast increasing demand for automotive fuels. The price, distribution infrastructure, and thermodynamic properties…

Decentralised ammonia production in the Netherlands

Decentralised ammonia production in the Netherlands

Hans Vrijenhoef

Our presentation will summarize the results of two government funded research projects Proton carried out over the last year. The presentation will give an overview of the Dutch power and chemicals (ammonia) markets. We will start by including a brief history of both markets, current trends and foreseen problems. We propose that electrification of the chemical industry will solve the anticipated problems.

Piloting a Combined Heat and Power / Distributed Generation System, Powered by Carbon-Free, Renewable-Based Anhydrous Ammonia

Peter Sinsheimer

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.…

Ammonia for Green Energy Storage and Beyond
Presentation

Ammonia for Green Energy Storage and Beyond

Ian Wilkinson

Siemens is participating in an all electric ammonia synthesis and energy storage system demonstration programme at Rutherford Appleton Laboratory, near Oxford. The demonstrator, which will run until December 2017, is supported by Innovate UK. Collaborators include the University of Oxford, Cardiff University and the Science & Technology Facilities Council.
