Sustainable Ammonia Production from Sun, Air and Water

Sustainable Ammonia Production from Sun, Air and Water

Dorottya GubanJosua VietenMartin RoebChristian Sattler

There is an ever growing demand for ammonia production that already reached globally 200 million tons per year by 2018 and is forecasted to increase to over 350 million tons per year by 2050 [1]. The application segment is dominated by the fertilizer industry, since the most important fertilizer and the world’s most widely produced chemical is urea. Ammonia is synthesized via the Haber-Bosch process, for which the required hydrogen and nitrogen are currently provided by using fossil fuels. This work proposes a novel approach to produce ammonia from the raw materials water and air only by utilizing solar energy…

Starfire Energy's 10 Kg/Day Rapid Ramp NH3 System Development

Joseph BeachJonathan KintnerAdam Welch

Starfire Energy is building a 10 kg/day NH3 synthesis system using its low pressure Rapid Ramp NH3 process. The system includes hydrogen production by proton exchange membrane electrolyzer, nitrogen production by pressure swing adsorption, NH3 synthesis, and liquid NH3 storage. The tight coupling of the hydrogen, nitrogen, and NH3 processes require minimal reactant buffering. The system design, status, and preliminary performance will be discussed.

Life-cycle analysis of green ammonia and its application as fertilizer building block

Life-cycle analysis of green ammonia and its application as fertilizer building block

Xinyu LiuAmgad Elgowainy

Conventionally, ammonia is produced from natural gas via steam methane reforming, water-gas shift reaction, and Haber-Bosch process. The process uses fossil fuels extensively and leads to 2.7 ton of CO2 emission per ton ammonia produced. With ammonia being the second largest chemical produced in the world, its production accounts for approximately 2% of worldwide fossil fuel use and generates over 420 million tons of CO2 annually. To decarbonize the ammonia sector, green ammonia synthesis pathways are of increasing interest. Green ammonia originates from air, water, and renewable electricity, and thus could be produced with low or zero carbon emissions. Since…

Technoeconomic Requirements for Sustainable Ammonia Production

Joshua M. McEnaneyNico PinkowskiBrian A. RohrJay SchwalbeMichael Statt

Ammonia, the feedstock for all nitrogen fertilizers, is produced via the Haber-Bosch process, which is responsible for 1-2% of global carbon dioxide emissions each year. An attractive solution to this problem is to create an electrochemical ammonia synthesis process that can produce ammonia using only air, water, and renewable electricity. Researchers across the world have been working toward such a solution for the last several decades, but so far, no economically viable alternative has been created. The Haber-Bosch process is one of the largest-scale, most highly optimized chemical processes in the world; it is very difficult to find a cheaper…

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

Yasushi FujimuraMototaka KaiTakayoshi FujimotoSho FujimotoRyousuke AtsumiMasayasu NishiTakehisa MochizukiTetsuya Nanba

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…

Solid Oxide Technology for Ammonia Production and Use

John Bøgild Hansen

The presentation will outline a 4 million € project funded by the Danish Energy Agency. The project is coordinated by Haldor Topsøe A/S and the partners are Vestas Wind Power, Ørsted, Energinet, Equinor, DTU Energy Conversion, and Aarhus University. The purpose of the project is to demonstrate a novel process for generation of ammonia synthesis gas without an air separation unit by means of Solid Oxide Electrolyzer Cells as well as using ammonia as a fuel for Solid Oxide Fuel Cells. The synthesis gas generation plant will be a 50 kW unit. The SOFC unit test will be carried out…

From Micro to Mega, how the green ammonia concept adapts

Rhys TuckerKaran Bagga

Green ammonia concepts from thyssenkrupp are available from 50 to over 5000 tonnes per day. Variability of electrolytic hydrogen feed presents one of the biggest and unique challenge in achieving an optimal and stable functioning of the Haber-Bosch synthesis loop. The solutions to these challenges require a customised approach, dependent on scale and power generation mix of the of the facility. At thyssenkrupp, Australia, we offer local expertise in optimising the concepts for your small and large scale green ammonia applications, underpinned by our know how as a world leading electrolysis and ammonia technology supplier.

Australia's hydrogen transition: Mobility projects as a catalyst to large-scale export

Claire Johnson

With Australia’s eye firmly fixed on becoming a major hydrogen export player, hydrogen mobility opportunities sometimes gets overlooked. Claire will discuss the important role that fuel cell vehicles and their infrastructure can play in enabling a hydrogen export sector in Australia, including the potential uptake rates out to 2030 and what governments need to do to make this happen.
