ACS "Ammonia Economy" Call for Papers Deadline Extended

Stephen H. Crolius March 23, 2017

The deadline for abstracts for the Ammonia Economy session at the American Chemical Society (ACS) National Meeting in August has been extended to April 3. This was reported in an interview yesterday with Martin Owen Jones, Energy Materials Coordinator for the ISIS neutron spallation facility at the Rutherford Appleton Laboratory in the United Kingdom. Jones is the co-organizer of the session along with Michael Mock, a Catalysis Scientist at Pacific Northwest National Laboratory (PNNL) in the U.S. The session will be the most prominent treatment of ammonia energy to date at a scientific conference held by an organization of global stature.

Bunker Ammonia: carbon-free liquid fuel for ships

Trevor Brown March 23, 2017

The shipping industry is beginning to evaluate ammonia as a potential "bunker fuel," a carbon-free alternative to the heavy fuel oil (HFO) used in maritime transport. International trade associations are leading the effort to decarbonize the sector, in alignment with targets set by the Paris Climate Agreement. Their immediate challenge is simple to state but hard to solve: "ambitious CO2 reduction objectives will only be achievable with alternative marine fuels which do not yet exist." In the long-term, however researchers recognize that "fuel cell-powered ships are likely to dominate, drawing their energy from fuels such as hydrogen and ammonia."

Terrestrial Energy and the Production of Carbon-Free Ammonia

Stephen H. Crolius March 16, 2017

On January 24, the nuclear energy company Terrestrial Energy USA informed the United States Nuclear Regulatory Commission of its plans “to license a small modular, advanced nuclear reactor in the United States.” Many steps later – sometime in the 2020s – the American subsidiary of the Canadian company Terrestrial Energy, Inc., hopes to bring its IMSR technology to market. IMSR stands for integral molten salt reactor. The IMSR stands apart from conventional nuclear technology on several dimensions. On the dimension of operating temperature, the IMSR is hot enough that it can be beneficially integrated with high-temperature industrial processes. According to the company’s research, ammonia production could be a candidate for such integration.

Progress in Ammonia Combustion Catalysts

Stephen H. Crolius March 08, 2017

On February 14 the Journal of Physical Chemistry published a paper entitled “Local Structures and Catalytic Ammonia Combustion Properties of Copper Oxides and Silver Supported on Aluminum Oxides.” The paper, by Satoshi Hinokuma of Kumamoto University in Kumamoto, Japan and four co-authors, reports on a catalyst system that is well adapted for use in ammonia energy applications.

Industrial demonstrations of ammonia fuel in Japan

Trevor Brown March 06, 2017

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 for energy storage: economic and technical analysis

Trevor Brown March 02, 2017

Developers around the world are looking at using ammonia as a form of energy storage, essentially turning an ammonia storage tank into a very large chemical battery. In the UK, Siemens is building an "all electric ammonia synthesis and energy storage system." In the Netherlands, Nuon is studying the feasibility of using Power-to-Ammonia "to convert high amounts of excess renewable power into ammonia, store it and burn it when renewable power supply is insufficient." While results from Siemens could be available in 2018, it might be 2021 before we see results from Nuon, whose "demonstration facility is planned to be completed in five years." But, while we wait for these real-world industrial data, the academic literature has just been updated with a significant new study on the design and performance of a grid-scale ammonia energy storage system.

Ammonia-Fueled Gas Turbine Power Generation

Ammonia Energy News February 16, 2017

Hideaki Kobayashi, professor at the Institute of Fluid Science at Tohoku University in Sendai, Japan, has developed the world’s first technology for direct combustion of ammonia in a gas turbine. The advance was made in cooperation with the National Institute of Advanced Industrial Science and Technology (AIST) under a program led by Norihiko Iki.
