 In October 2020, Japan declared that it aims to achieve carbon neutrality by 2050.
 The Ministry of Economy, Trade and Industry in collaboration with other ministries and agencies,
formulated the “Green Growth Strategy through Achieving Carbon Neutrality in 2050”.
 This strategy specifies 14 promising fields that are expected to grow and provides action plans forthem from the viewpoints of both industrial and energy policies.

Project Overview

Next-generation Ship Development
 In the shipping sector, hydrogen, ammonia, and carbon-recycled methane are expected to be
used as zero-emission ship fuels; however, their adoption will depend considerably on the fuelprices and the development of the fuel supply infrastructure.
 In this project, we will develop and demonstrate the engine, fuel tank, fuel supply system, andother components for next-generation ships and develop the infrastructure for ammonia fuel supply
to ships, including the developing of an ammonia bunkering ship.

Project Overview

Next-generation Aircraft Development
 To realize carbon neutrality in the aviation field, realizing sustainable aviation fuels (SAFs) andinnovations such as aircraft weight reduction, engine efficiency improvement andelectrification, hydrogen aircraft development, etc. are necessary.
 Entire aircraft is developed by European and American OEM manufacturers (Boeing, Airbus). Japan
will develop core technologies for hydrogen aircraft and technologies for lightweight primarystructural components with complex shapes for them.

Project Overview

Large-scale Hydrogen Supply Chain Establishment
 Toward the realization of a hydrogen society, the project will promote the construction of a largescale hydrogen supply chain as well as demand creation.
 Using multiple hydrogen carriers (liquefied hydrogen, methylcyclohexane (MCH)), the project aims toreducing supply costs to 30 yen/Nm3 in 2030 and 20 yen/Nm3 or lesser in 2050 (equivalent tofossil fuels) by the development and demonstration of large-scale transportation equipment
and hydrogen combustion stability in actual hydrogen power generation equipment.

Project Overview

Hydrogen Production through Water Electrolysis
Using Power from Renewables

 To establish domestic hydrogen production bases that utilize surplus renewables, etc. and to acquire
the overseas market, this project aims to further reduce the equipment cost (up to approximately
1/6 of the current cost) by increasing the size and modularizing multiple types of waterelectrolyzers (alkaline and polymer electrolyte membrane (PEM) types), implementing
membranes, and demonstrating power-to-X systems.

 Ammonia supply is limited to raw materials such as fertilizers; therefore, building a large-scale fuelammonia supply chain integrating use and supply sides is necessary.
 We will develop and demonstrate a manufacturing method for fuel ammonia with large-scale
production, cost reduction, and reduction in CO2 emissions, as well as develop technologies
for high-mixed and single firing.
Ammonia synthesis technology

Green ammonia synthesis

Manufacture of burners

 Developed a synthetic method superior to theHaber–Bosch method to reduce the synthesis
cost of blue ammonia (at least 15%).

 By the development of catalysts andelectrolytes, we will develop a newproduction method without using hydrogen torealize cost reductions for green ammonia.

 Aiming for high-mixed and single firing inboilers and gas turbines, we will develop
high-mixed and single firing burners (50% ormore in actual equipment).
