Demonstration project for a green chemical plant using large-scale alkaline water electrolysis

Yohei Shimada Mototaka Kai Shuya Takakuwa Satoshi Katsuike

To achieve the carbon neutrality target set to be accomplished by 2050, hydrogen will play an important role in many sectors such as power, transportation, and industrial applications. Especially in the chemicals and fertilizers sectors, green ammonia, made by utilizing renewable energy as a feed stock, is expected to be materialized, and is also being considered as a hydrogen carrier with the advantage of easier transportation and handling than the hydrogen itself. Hence, in the near future, green chemical production facilities which are fed with hydrogen produced through the use of renewable energy will be installed instead of the conventional…

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…

Cost Evaluation Study on CO2-Free Ammonia and Coal Co-Fired Power Generation Integrated with Cost of CCS

Kazutaka Hiraoka Yasushi Fujimura Yoshiyuki Watanabe Mototaka Kai Ko Sakata Yuki Ishimoto Yuji Mizuno

This study presents a cost estimation for electricity generated by CO2-free ammonia and coal co-firing. Regulation of CO2 emissions seems to be gaining pace due to the global warming issue so the introduction of CO2-free energy in power generation has become desirable. Ammonia is one of the potential energy carriers for power generation and development of ammonia combustion technology with low NOx emissions has been conducted in Japan. In order to investigate the feasibility of the introduction of CO2-free ammonia in Japan from both the technical and economic viewpoints, we estimated the ammonia supply chain cost from ammonia production integrated…
