In order to abide by the Paris Agreement, it is necessary for CO2 emissions to be reduced to net zero in the second half of this century, and in other words, fuel that emits no CO2 (CO2-free fuel) is in demand. Among such fuel, ammonia is a portable fuel which is easy to carry, and it can be easily produced from natural gas. In addition, the capture and storage of CO2 emitted in the production of ammonia prevent the emission of CO2. The production of ammonia has a long history, and it is now distributed at relatively low prices throughout the world. The use of ammonia by direct combustion is also becoming feasible through research on Energy Carriers in the Strategic Innovation Promotion Program (SIP). We hope that a system for using CO2-free fuel will be developed and such fuel will be used to prevent global warming.
