The Evolving Context of Ammonia-Coal Co-Firing

Co-firing ammonia in a coal-fueled boiler, a concept under active development in Japan, received positive notice in the International Energy Agency’s recently published report, The Future of Hydrogen. So far serious scrutiny of the co-firing concept is limited to Japan.  In the fullness of time, the demand side of the concept may take root in other countries.  The supply side, however, could have near-term global relevance.

The global quest to decarbonize ammonia production

NEWS BRIEF: The industrial process for ammonia production is increasingly being recognized as a target for decarbonization - by researchers, investors, regulators, and the producers themselves. Demonstrating this shift in awareness, Chemical and Engineering News (C&EN), one of the flagship publications of the American Chemical Society (ACS), this week published an in-depth review of global research and development efforts and demonstration plants for sustainable ammonia synthesis. Its review is all-encompassing, from near-term feasible renewable Haber-Bosch plants, to long-term research areas of electrochemistry, photocatalysis, and bioengineering.

New Video Summarizes SIP Energy Carriers Accomplishments

ANNOUNCEMENT: The Japanese Government’s Cabinet Office and the Japan Science and Technology Agency have released an English-language video that summarizes the accomplishments of the Cross-Ministerial Strategic Innovation Promotion Program’s Energy Carriers initiative.  The release coincides with the end-of-March conclusion of Energy Carriers’ work, and anticipates this month’s formal activation of the Green Ammonia Consortium.

JGC Corporation demonstrates “world’s first” carbon-free ammonia energy cycle

In late 2018, JGC Corporation issued a press release to celebrate a "world's first" in ammonia energy, demonstrating at its pilot plant in Koriyama both "synthesis of ammonia with hydrogen produced through the electrolysis of water by renewable energy, and generation of electricity through gas turbines fueled by synthesized ammonia."

By demonstrating the feasibility of using ammonia on both sides of the renewable energy equation -- first, producing green ammonia from intermittent renewable electricity and, second, combusting this carbon-free fuel for power generation -- the project demonstrates the role of ammonia in the "establishment of an energy chain ... that does not emit CO2 (CO2-free) from production to power generation."

Green ammonia demonstration plants now operational, in Oxford and Fukushima

Two new pilot projects for producing "green ammonia" from renewable electricity are now up and running and successfully producing ammonia.

In April 2018, the Ammonia Manufacturing Pilot Plant for Renewable Energy started up at the Fukushima Renewable Energy Institute - AIST (FREA) in Japan. Earlier this week, Siemens launched operations at its Green Ammonia Demonstrator, at the Rutherford Appleton Laboratory outside Oxford in the UK.

The commercial product coming out of these plants is not ammonia, however, it is knowledge.

While both the FREA and Siemens plants are of similar scale, with respective ammonia capacities of 20 and 30 kg per day, they have very different objectives. At FREA, the pilot project supports catalyst development with the goal of enabling efficient low-pressure, low-temperature ammonia synthesis. At Siemens, the pilot will provide insights into the business case for ammonia as a market-flexible energy storage vector.

Green Ammonia Consortium: Bright Prospects in Japan for Ammonia as an Energy Carrier

In the last 12 months ...
In July 2017, 19 companies and three research institutions came together to form the Green Ammonia Consortium. Before this development, it was unclear whether ammonia would find a significant role in Japan’s hydrogen economy. In the wake of this announcement, however, ammonia seems to have claimed the leading position in the race among potential energy carriers.

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.
