Small-Scale Ammonia Synthesis Technology on Track for 2021

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.

Effect of Preparation Condition on Ammonia Synthesis over Ru/CeO

Development of the hydrogen carrier system is of great interest to utilization of renewable energy. To store renewable energy, especially for the electricity from photovoltaic and wind turbine, fluctuation of the generated electricity is not appropriate for the stable supply of the electric power. Also, the hydrogen production by the water electrolysis with the fluctuating electricity results in the fluctuation of hydrogen production. When we store the hydrogen derived from renewable energy in the carrier compounds, it is necessary to consider the reduction or smoothing of fluctuation in the hydrogen flow rate as a feed of chemical process. Although the…

Synthesis and Assessment of Process Systems for Production of Ammonia Using Nitric Oxide in Combustion Exhaust Gas

Recently, ammonia is regarded as an alternative fuel without carbon dioxide (CO2). Numerous studies have been performed using ammonia as a fuel. Iki and Kurata confirmed the working of a prototype for the ammonia gas turbine, where ammonia burned in an environmentally benign way to generate electricity, exhausting only water and nitrogen [1]. From the view of cycle of ammonia for the development of a society with low carbon, it is required to synthesize carbon-free ammonia (green ammonia) in small plants. This green ammonia can be synthesized using renewable energy, with hydrogen from electrolysis of water and nitrogen from pressure…

NH3 Fuel Association Announces Charter Sponsors

The NH3 Fuel Association (NH3FA) has released the names of the organization’s charter group of sponsors. The common thread that unites the six companies? A conviction that ammonia energy represents a significant opportunity for their businesses. The sponsors are Yara, Nel Hydrogen, Airgas, Haldor Topsoe, Casale, and Terrestrial Energy.

The Ammonia Economy at the ACS National Meeting

The American Chemical Society (ACS) has published the program for its 2017 National Meeting, which takes place next month in Washington DC and includes a session dedicated to the "Ammonia Economy." The first day of the week-long meeting, Sunday August 20th, will feature a full morning of technical papers from the US, UK, and Japan, covering ammonia energy topics across three general areas: producing hydrogen from ammonia, developing new catalysts for ammonia synthesis and oxidation, and storing ammonia in solid chemical form.

Low-carbon ammonia synthesis: Japan’s ‘Energy Carriers’

In 2018, a pilot plant in Japan will demonstrate a new way to produce ammonia at industrial-scale, with a low carbon footprint. This is part of Japan's 'Energy Carriers' R&D initiative, which aims to develop technologies to enable the nation's transition to a carbon-free hydrogen economy. The scope of the program covers ten subjects that encompass the full "CO2-free hydrogen value chain." Three of these ten programs describe a technology pathway for making low-carbon ammonia.

How to create a market for low-carbon ammonia: product labeling

I wrote last week about ARPA-E's "transformative" ammonia synthesis technologies, describing three technology pathways under development: low pressure Haber-Bosch, electrochemical processes, and advanced electrolysis. ARPA-E's ambitious R&D program might imply that a meaningful, commercial market for sustainable ammonia is still decades away. It represents, however, only the slow American tip of a fast-moving global iceberg. In Japan, where there's no debate about climate science, the national effort is already well underway, with three programs to develop low-carbon ammonia synthesis under the Cross-ministerial Strategic Innovation Promotion Program (SIP), 'Energy Carriers.'

Australia’s Concentrated Solar Fuels Program

Solar ammonia' could be the key to the sustainable energy economies of two nations. During his talk at the 2016 NH3 Fuel Conference, Keith Lovegrove, Head of Solar Thermal at IT Power Group in Australia, said that Japan and Australia have the opportunity to move their trade in energy onto a climate-friendly foundation. This would involve development of Australia's solar resources in a way that helps Japan ramp up its Strategy for Hydrogen & Fuel Cells in the coming decades.
