Tsubame BHB Launches Joint Evaluation with Mitsubishi Chemical

Stephen H. Crolius December 17, 2020

Last month Tsubame BHB, a Japanese developer of ammonia synthesis technology, announced the signing of a “joint evaluation contract” with Mitsubishi Chemical Corporation (MCC) that will focus on a novel ammonia separation membrane. The company, which started operations in 2017, is working on a method of ammonia synthesis that could allow economic production at scales 1-2 orders of magnitude below today’s plants.

Observations on green ammonia production scaleup and the potential for job creation

Rhys Tucker

Green ammonia provides Australia with the opportunity to export our abundant renewable resources. A key benefit to the nation is the jobs created in an expanded ammonia export industry, allowing transition from carbon-based energy to cleaner sources. Drawing on cases study analysis of green ammonia plants scaled from 25 to 2500 tonnes of ammonia per day, the impact of a range of production cost elements is assessed focusing on ammonia production.

Small-Scale Ammonia Synthesis Technology on Track for 2021

Stephen H. Crolius December 12, 2019

On October 6, 2019, the Nihon Keizai Shimbun published an article that confirmed a goal set at the 2017 launch of Japanese chemical technology developer Tsubame BHB. The goal is to have Tsubame’s ammonia synthesis technology ready for licensing in 2021. According to Tsubame’s English-language Web site, its technology “makes it possible to produce ammonia even at small-scale plants” – good news for ammonia energy project developers interested in distributed production concepts.

Ammonia Absorbents with High Stability and High Capacity for Fast Cycling

Matthew Kale Joshua I. Militti Sayandeep Biswas Alon McCormick Paul Dauenhauer Edward Cussler

Ammonia absorption is an alternative separation to condensation in ammonia production. Metal chloride salts selectively incorporate ammonia into their crystal lattices with remarkably high capacity. Regeneration and stability of these salts are further improved by dispersing them onto a porous silica support. Here, we discuss the optimal preparation methods of supported metal halides, as well as optimal conditions for uptake and release of ammonia. The metal halide salt particle size, support particle size, support composition and preparation methods are optimized for material stability, speed of uptake and release, and maximum ammonia capacity. An automated system was used to rapidly screen…

Comparative Technoeconomic Analysis of Conventional and Absorbent-Enhanced Ammonia Synthesis

Matthew Palys Alon McCormick Edward Cussler Prodromos Daoutidis

Ammonia is the second-most produced synthetic chemical and the main precursor for nitrogen-based fertilizer. In 2015, 160 million tons were produced globally, and global demand is expected to grow 1.5% annually until 2050 [1]. However, traditional ammonia production uses natural gas or coal as its hydrogen source, and as a result, is also responsible for more than 1% of global GHG emissions and 5% of global natural gas consumption [2]. Clearly, a more sustainable ammonia production scheme is needed. One such alternative is obtain hydrogen from electrolysis powered by wind- or solar-derived electricity. It has been proposed to perform this…

Ammonia as an Energy Carrier – Update from the Netherlands

Hans Vrijenhoef Jacco Mooijer

Proton Ventures specializes in ammonia and energy related matters in four ways: Terminal storage and handling (bulk) NFUEL Small scale ammonia production DeNOx and N2O removal systems Battolyser Technology (electrolysis and battery storage in a single appliance) Recently, Proton Ventures welcomed new venture capital from Koolen Industries allowing further growth, development and market penetration of the new small scale ammonia production technology. Momentum is increasing: across the globe, we have some great leads in various stages of development. Can multiple small scale production trains actually be a smart solution for the larger production capacity requirements when fluctuation of either the…

Arpa-E Refuel Program: Distributed Production of Ammonia and Its Conversion to Energy

Grigorii Soloveichik

Ammonia, which has high energy density in easily produced liquid form and can be converted to electric or motive power, is considered to be an almost ideal non-carbon energy vector in addition to its common use as a fertilizer. It can be manufactured anywhere using the Haber-Bosch process, effectively stored, transported and used in combustion engines and fuel cells as well as a hydrogen carrier. Transition from fossil fuels as the energy source and feedstock to intermittent renewable energy sources will require a shift from large scale Haber-Bosch plants (1,000 – 1,500 t/day) to distributed ammonia production matching electrical power…

Optimizing Absorptive Separation for Intensification of Ammonia Production

Bosong Lin Fouzia Nowrin Mahdi Malmali

High pressure requirements of Haber-Bosch process imposes substantial operating (e.g., compression) and capital (compressor cost, advanced costly alloys, thick reactor casing, etc.) expenses in the ammonia production. Cost considerations force ammonia producers to take advantage of the economy of scale to drive down the manufacture cost, while small and energy-efficient processes that can be powered with off-grid renewable energy are required for ammonia-mediated hydrogen economy. Small-scale reaction-absorption process is proposed to be a viable technology to reduce the operating pressure requirements of Haber-Bosch process.1–4 Here, we present an overview of our efforts to further intensify ammonia production via reaction-absorption process.…

Technoeconomic Requirements for Sustainable Ammonia Production

Joshua M. McEnaney Nico Pinkowski Brian A. Rohr Jay Schwalbe Michael 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…
