Ammonia energy is now a talking point for CEOs

Chief executives of major corporations are now talking about ammonia energy. This represents another crucial step up the learning curve for clean industry: knowledge about ammonia's potential has successfully spread from the R&D department to the executive suite. This is the difference between development and deployment. The fertilizer industry saw this in 2018, when the CEOs of first movers like Yara and OCP announced green ammonia pilot plants. These latest announcements come, however, from the shipping and power sectors — far bigger industries, with no existing ammonia business — and they focus on the use of green ammonia: for fuel and for profit.

New Technology of the Ammonia Co-Firing with Pulverized Coal to Reduce the NOx Emission

Ammonia is recognized as the new energy carrier and it is expected to be introduced into the society in a short time, since the infrastructures related to the ammonia, such as the mass production, transportation and storage are already introduced to produce the fertilizer for the agriculture. There is one technical issue, to use the ammonia in the direct combustion as the fuel for the electric power generation. It is the increase of the NO concentration in the exhaust gas. Ammonia contains the large amount of the nitrogen, comparing with any other fuels that human being has ever treated. Nitrogen…

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.

Test Results of the Ammonia Mixed Combustion at Mizushima Power Station Unit No.2 and Related Patent Applications

At the Mizushima Power Station Unit No.2 (Coal-fired, Location: Kurashiki, Okayama Prefecture, rated output: 156,000 kW), the Chugoku Electric Power Company conducted the ammonia mixed-combustion test from July 3 to 9, 2017, in order to reduce the environmental burden of coal-fired power stations. We compile the test results and report it to Japan Science and Technology Agency (JST), and we are pleased to inform you today that we applied for patents on the findings obtained in this examination. This test is part of the “ammonia direct burning” as a commissioned research topic on “energy carriers” out of the “Strategic Innovation…

Basic Co-Firing Characteristics of Ammonia with Pulverized Coal in a Single Burner Test Furnace

Ammonia is expected as a potential fuel to substitute fossil fuels, because it does not discharge carbon dioxide and is easily handled by liquefaction. There are several ways for the direct use of ammonia as a fuel; for example, use in fuel cells and combustion devices. One of the possible application is the combustion use in thermal power plants. In particular, co-firing of ammonia in coal-fired power plants seems to have a relatively great advantage on the suppression of greenhouse gases, because coal is one of the main emission source of carbon dioxide. On the other hand, it is concerned…

Cost Evaluation Study on CO2-Free Ammonia and Coal Co-Fired Power Generation Integrated with Cost of CCS

This study presents a cost estimation for electricity generated by CO2-free ammonia and coal co-firing. Regulation of CO2 emissions seems to be gaining pace due to the global warming issue so the introduction of CO2-free energy in power generation has become desirable. Ammonia is one of the potential energy carriers for power generation and development of ammonia combustion technology with low NOx emissions has been conducted in Japan. In order to investigate the feasibility of the introduction of CO2-free ammonia in Japan from both the technical and economic viewpoints, we estimated the ammonia supply chain cost from ammonia production integrated…

IHI First to Reach 20% Ammonia-Coal Co-Firing Milestone

The Japanese manufacturer IHI Corporation announced on March 28 that it had successfully demonstrated the co-firing of ammonia and coal in a fuel mix composed of 20% ammonia. Ammonia-coal co-firing had previously been demonstrated by Chugoku Electric in a fuel mix composed of just 0.6-0.8% ammonia. IHI says its ultimate goal is to “construct a value chain that connects the production and use of ammonia, using combustion technology of gas turbines and coal-fired boilers, using ammonia as fuel.”
