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.”

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.
