Demonstration and Optimization of Green Ammonia Production Operation Responding to Fluctuating Hydrogen Production from Renewable Energy

Yasushi Fujimura Mototaka Kai Takayoshi Fujimoto Sho Fujimoto Ryousuke Atsumi Masayasu Nishi Takehisa Mochizuki Tetsuya Nanba

Ammonia is a promising hydrogen carrier to transport green hydrogen from overseas to Japan at lower cost and resulting in lower lifecycle CO2 emission. Low carbon ammonia will be produced by fossil fuel reforming with CCS or EOR at the early stage of the introduction of ammonia fuel to the market. Green ammonia production from renewable sources is the ultimate goal, but there are some issues to commercialize. The low capacity factor, which is caused by the fluctuation of solar irradiation or wind speed, is a big issue which leads to ammonia production costs. In this presentation, we would like…

Demonstration of CO2-Free Ammonia Synthesis Using Renewable Energy-Generated Hydrogen

Mototaka Kai Yasushi Fujimura Takayoshi Fujimoto Hideyuki Takagi Yuichi Manaka Tetsuya Nanba

In Japan, the government funding project SIP, Strategic Innovation Promotion Program, supports the research, development and demonstration of “Energy Carriers”. The concept of the “Energy Carriers” value chain is to produce hydrogen energy carriers overseas from fossil resources using CCS or renewable energy, and transport it to Japan for utilization as clean energy. The purpose of the program is to help realize a low-carbon society in Japan by using hydrogen. Among energy carriers, ammonia is the one of the most promising carriers, because of the ease of transportation as a liquid, higher hydrogen density, and proven technologies for commercial and…
