Tsubame BHB Launches Joint Evaluation with Mitsubishi Chemical

By on 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

By on August 27, 2020
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

By on 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

By , , , , and on November 14, 2019
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…

Ammonia as an Energy Carrier – Update from the Netherlands

By and on November 13, 2019
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…

Optimizing Absorptive Separation for Intensification of Ammonia Production

By , and on November 12, 2019
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.…

From Micro to Mega, how the green ammonia concept adapts

By and on August 23, 2019
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.
