Fusion energy is expected to be a permanent "dream energy source" because it does not emit CO2 and fuel for the fusion reaction exists abundantly in seawater. Recently, many fusion startups have been established inside and outside of Japan, and they are developing their technologies while backed by a large amount of funds. Japan is participating in the International Thermonuclear Experimental Reactor (ITER) project, which is being promoted through international cooperation, and is developing in parallel a fusion DEMO reactor in Japan. Mitsubishi Heavy Industries, Ltd. is contributing to the construction of ITER by actual-component manufacturing toroidal field coils and divertors, which are important components for fusion reactions in ITER. In the development of the fusion DEMO reactor, we are promoting design activities based on the knowledge accumulated in Light Water Reactor and ITER projects.
