Progress toward Ammonia-to-Hydrogen Conversion at H2 Fueling Stations

In the last 12 months ...
Groups in Australia, Japan, Denmark, the U.K., and the U.S. all made progress with technologies that can be used to convert ammonia to hydrogen at fueling stations. This means that hydrogen for fuel cell vehicles can be handled as ammonia from the point of production to the point of dispensing.

On the Ground in Japan: FCV Uptake and Hydrogen Fueling Stations

Module four of the ten-module research and development agenda for Japan’s Cross-Ministerial Strategic Innovation Promotion Program -- Energy Carriers is entitled “Basic Technology for Hydrogen Station Utilizing Ammonia.” The rationale for including this technology is that “high purity H2 supply system with low cost hydrogen transportation is a key issue to spread fuel cell vehicles (FCVs).”

A story published last week in the Tokyo Shimbun says that to date FCVs have not spread very far. Among the factors seen as constraints is the cost of hydrogen fueling stations (HFS). The Tokyo Shimbun story states that “according to industry officials, each station that supplies hydrogen to fuel cell vehicles runs about ¥400 million ($3.6 million) in construction costs. In order to achieve profitability, about 1,000 fuel cell vehicles are required as customers per location. Construction is not proceeding.”

So far, the players focused on FCVs do not seem to be looking to ammonia as an expedient that will help reduce the cost of HFS and thereby encourage their construction and by extension the uptake of FCVs. This appears to be a missed opportunity whose benefits may become too compelling to ignore.

New Technology for Generating Hydrogen from Ammonia

On March 21, Gifu University in Japan announced a breakthrough in technology for generating hydrogen from ammonia. A press release from the Gifu Prefectural Association Press Club stated that Professor Shinji Kambara, Director of the Next Generation Research Center within the Environmental Energy Systems Department at the Gifu University Graduate School of Engineering, has developed a "plasma membrane reactor" that is capable of evolving hydrogen with a purity of 99.999 percent from an ammonia feedstock. This surpasses the 99.97 percent purity announced last July by a research group centered at Hiroshima University with a hydrogen generation device based on a different technology.
