Round-trip Efficiency of Ammonia as a Renewable Energy Transportation Media

A new study has made a major addition to the available literature on the economic benefits of ammonia energy. This latest study, published by researchers from CSIRO in Australia, provides the data needed to define the round-trip efficiency of using ammonia as a sustainable fuel and hydrogen carrier.

SIP “Energy Carriers” video: ammonia turbines, industrial furnaces, fuel cells

To demonstrate the progress of the SIP "Energy Carriers" program, the Japan Science and Technology Agency last week released a video, embedded below, that shows three of its ammonia fuel research and development projects in operation.

R&D is often an abstract idea: this video shows what it looks like to generate power from ammonia.

As it turns out, fuel cells aren't hugely photogenic. Nonetheless, if a picture is worth a thousand words, this will be a long article.

Advances in Ammonia-Fired Gas Turbines Open Up Major Use Case

In the last 12 months ...
Researchers seeking to fire gas turbines with ammonia made significant strides toward realization of commercial-scale machines in both the U.K. and Japan. This means that electricity generation has become a realistic near-term use-case for ammonia energy.

Report from the European Conference: Ammonia-Fueled Gas Turbines

The ammonia-fueled gas turbine (A-GT) seems destined to become one of the key technologies in the sustainable energy economy of the future.  Siemens AG, for one, features the A-GT in its vision for “Green Ammonia for Energy Storage and Beyond” and the demonstration system that the company is building at the Rutherford Appleton Laboratory in the U.K.  Last month Ian Wilkinson, Siemens’ Programme Manager for the demonstration project, spoke about the project’s progress at the 1st European Power to Ammonia® Conference in Rotterdam in The Netherlands.  Although he devoted a slide to the A-GT, the detailed perspective came from another presentation at the conference.  This one was delivered by Dr. Agustin Valera-Medina, a Senior Lecturer at Cardiff University, one of Siemens’ main green ammonia collaborators.

Power to Ammonia: the Eemshaven case

The Institute for Sustainable Process Technology recently published a feasibility study, Power to Ammonia, looking at the possibility of producing and using ammonia in the renewable power sector. This project is based in The Netherlands and is led by a powerful industrial consortium.

I wrote about the feasibility study last month, but it deserves closer attention because it examines three entirely separate business cases for integrating ammonia into a renewable energy economy, centered on three site-specific participants in the study: Nuon at Eemshaven, Stedin at Goeree-Overflakkee, and OCI Nitrogen at Geleen.

Over the next few years, the group intends to build pilot projects to develop and demonstrate the necessary technologies. Next month, however, these projects will be an important part of the Power-to-Ammonia Conference, in Rotterdam on May 18-19.

This article is the first in a series of three that aims to introduce each business case.

Ammonia – and Other Nitrogen-Based Fuels

Next month the print edition of Fuel Processing Technology will feature a paper entitled “Auto-ignition of a carbon-free aqueous ammonia/ammonium nitrate monofuel: a thermal and barometric analysis.” This title is provocative. First, what is this idea of a fuel composed of a mixture of ammonia and ammonium nitrate (AN)? If ammonia is a good fuel, is it made better with the addition of ammonium nitrate? Second, why is it aqueous? Is the presence of water a feature or a bug? Third, what is a monofuel and why is this term used when the fuel is a mixture of two molecular species? And finally, why is the paper ultimately about auto-ignition?

Power to Ammonia feasibility study

The Institute for Sustainable Process Technology has just published a feasibility study that represents a major step toward commercializing renewable ammonia.

It examines the "value chains and business cases to produce CO2-free ammonia," analysing the potential for commercial deployment at three companies with existing sites in The Netherlands: Nuon at Eemshaven, Stedin at Goeree-Overflakkee, and OCI Nitrogen at Geleen. The project is called Power to Ammonia.

Industrial demonstrations of ammonia fuel in Japan

Most of the ammonia energy projects I write about are in the research and development phase but, as I've said before, technology transfer from the academic lab to commercial deployment is moving swiftly - especially in Japan.

Last week, Nikkei Asian Review published two articles outlining plans by major engineering and power firms to build utility-scale demonstrations using ammonia as a fuel for electricity generation. Both projects aim to reduce the carbon intensity of the Japanese electrical grid, incrementally but significantly, by displacing a portion of the fossil fuels with ammonia. The first project will generate power using an ammonia-coal mix, while the second will combine ammonia with natural gas.

Ammonia Turbine Power Generation with Reduced NOx

A common concern with ammonia fuel is that NOx emissions will be too high to control. However, in new research from Turkey, USA, and Japan, presented at this year's NH3 Fuel Conference in September 2016, two things became clear.

First, NOx emissions can be reduced to less than 10ppm by employing good engineering design and exploiting the chemical properties of ammonia, which plays a dual role as both the fuel and the emissions-cleanup agent.

Second, the deployment of ammonia-fueled turbines for power generation is not only feasible, but actively being developed, with demonstration units running today and improved demonstration projects currently in development.

Japan’s Fourth Strategic Energy Plan

The Cabinet of the Government of Japan adopted the country’s Fourth Strategic Energy Plan in April 2014. The Plan includes a Strategy for Hydrogen & Fuel Cells which is being executed by the Ministry of Economy, Trade and Industry (METI). The accompanying H2/FC Road Map includes an investigation of three materials that can carry the energy embodied in molecular hydrogen: liquid hydrogen, organic hydrides such as methylcyclohexane, and ammonia.
