Cardiff University Launches Ammonia Gas Turbine Project

Last week Agustin Valera-Medina, Associate Professor at Cardiff University in the United Kingdom, told Ammonia Energy that work is underway on a £1.9 million (USD $2.3 million) project that will advance the frontiers of ammonia-gas turbine (AGT) technology. Valera-Medina is serving as the Principal Investigator of the Storage of Ammonia for Energy (SAFE) – AGT Pilot, a four-year effort that hopes to develop “a unique, competitive technology that can be implemented to support the hydrogen transition.”

Performance of Ammonia/Natural Gas Co-Fired Gas Turbine with Two-Stage Combustor

Ammonia has several advantages as renewable energy career [1-3]. Regarding the manufacturing process, the Harbor-Bosch method is already established. For transportation, ammonia can easily be liquefied at room temperature. Therefore, both transportation and storage are much easier than in case of hydrogen. In utilization, ammonia is combustible and used as a carbon-free fuel. However, ammonia has different combustion characteristics from natural gas. For example, the nitrogen atom contained in ammonia molecule causes high NOx emission through fuel NOx mechanisms [3]. Laminar burning velocity of ammonia is much lower; it might increase unburnt ammonia emission and cause unstable operation of gas…

Pure Ammonia Combustion Micro Gas Turbine System

To protect against global warming, a massive influx of renewable energy is expected. Although hydrogen is a renewable media, its storage and transportation in large quantity has some problems. Ammonia fuel, however, is a hydrogen energy carrier and carbon-free fuel, and its storage and transportation technology is already established. In the 1960s, development of ammonia combustion gas turbines was abandoned because combustion efficiency was unacceptably low [1]. Recent demand for hydrogen energy carriers has revived the interest in ammonia as fuel [2, 3]. In 2015, ammonia-combustion gas turbine power generation was reported in Japan using a 50-kW class micro gas…

IHI Corporation pushes its ammonia combustion technologies closer to commercialization

This week, an article in Japan Chemical Daily disclosed IHI Corporation's future plans for its range of ammonia combustion technologies, each of which has been demonstrated in the last year. These include "ammonia-coal co-fired thermal power boilers, ammonia-fired gas turbines and direct ammonia solid oxide fuel cells (SOFCs)." Under the headline "IHI Speeds up Development of Several Ammonia-Based Technologies," the article describes the company's ambitions for scaling-up each of these technologies, and provides a schedule for its next set of demonstration projects.

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.

Ammonia for Power: a literature review

"Ammonia for Power" is an open-access literature review that includes over 300 citations for recent and ongoing research in the use of ammonia in engines, fuel cells, and turbines, as well as providing references to decades of historical case studies and publications. The review, written by a consortium of ammonia energy experts from the University of Cardiff, University of Oxford, the UK's Science and Technology Facilities Council, and Tsinghua University in China, can be found in the November 2018 edition of Progress in Energy and Combustion Science.

IHI Commits to Ammonia Energy. Big Time.

During his presentation at the November 2017 NH3 Energy + Topical Conference, Shogo Onishi of IHI Corporation described the progress made by IHI and Tohoku University in limiting NOx emissions from ammonia-fired gas turbines (AGTs).  Regular attendees of the annual NH3 Fuel Conference identify IHI with its work on AGTs since the company also addressed this topic at the 2016 and 2015 events.  However, a scan of published materials shows that AGTs are just one aspect of IHI’s activity in the ammonia energy arena.  In fact, IHI is also looking at the near-term commercialization of technologies in ammonia-coal co-firing in steam boilers and direct ammonia fuel cells.  This level and breadth of commitment to ammonia energy is unique among global capital goods producers.

Green Ammonia Consortium Comes to the Fore in Japan

On December 8, the Nikkei Sangyo Shimbun ran a story about the future of coal-fired electricity generation in Japan.  The story touched on topics ranging from the plumbing in a Chugoku Electric generating station to the Trump administration’s idiosyncratic approach to environmental diplomacy.  And it contained this sentence: “Ammonia can become a ‘savior’ of coal-fired power.” Clearly an explanation is in order.
