The Cost of CO2-free Ammonia
Article

If ammonia is to be introduced into the energy system as a CO2-free fuel, its cost must be at least competitive with that of other CO2-free fuels such as CO2-free hydrogen. In the discussion below I consider the cost aspect of CO2-free ammonia. To state my conclusion at the beginning, the cost of CO2-free ammonia can be less than 30 yen/Nm3-H2, which is the 2030 cost target for hydrogen energy set by the Japanese government in its "Basic Hydrogen Strategy” for introducing hydrogen energy into Japan.

A Deep Dive into SIP “Energy Carriers” Ammonia Combustion Research (second half)
Article

From 2014 to 2018 Bunro Shiozawa served as Deputy Program Director of the SIP “Energy Carriers” initiative in Japan. Over the last year he has published a ten-part series of articles that describe and reflect on the research supported by the initiative. Part 4 covers ammonia combustion technologies. The first half of the article was posted on September 23, 2020, in Shiozawa's English translation. The second half follows.

Series Presents Japanese Perspective on Ammonia as a CO2-Free Fuel
Article

From 2014 to 2018, I served as Deputy Program Director of SIP “Energy Carriers” under Mr. Shigeru Muraki, Program Director, and alongside my fellow Deputy Program Director, Dr. Ken-ichi Aika. After helping to bring the Energy Carriers' work to a successful conclusion, I decided to write a series of articles that describe prospects for ammonia as a CO2-free fuel and hydrogen carrier, as well as activities to construct a value chain of CO2-free ammonia. The articles were published in the on-line journal of Japan’s International Environment and Economy Institute (IEEI).
