Welcome to this special edition of our technical review featuring carbon neutrality.
With increasing awareness of global warming and climate change as common challenges facing
humanity, each country is accelerating its efforts for decarbonization. On the other hand, it is alsoessential to sincerely work on the issues to realize an energy supply that is economical and stable.
We consider it necessary to tap the technologies and resources of Mitsubishi Heavy Industries, Ltd.
(MHI) Group and advance our efforts.
Under such circumstances, in October 2021, MHI Group released the “Carbon Neutrality
Declaration by 2040” with the theme of “MISSION NET ZERO”. Many countries including Japan
have pledged to achieve carbon neutrality by 2050. To fulfill this goal, we have set the target year
for Net Zero CO2 emissions as 2040, a decade earlier than the government, considering the leadtime required for our products and technologies to be implemented in society. Although this is quite
ambitious goal setting, it is our responsibility as a company that has long been supporting social
infrastructure. Our approach is to focus on the two areas of growth we have set: “EnergyTransition” aiming to decarbonize the energy supply side, and “Smart Infrastructure” to realize
decarbonization, energy conservation, and less labor-intensiveness on the energy use side.
In this edition, some of the MHI Group’s “MISSION NET ZERO" initiatives for carbon
neutrality are presented in 19 reports.
The first set of reports focuses on the “Energy Transition”, which pertains to the initiatives on theenergy supply side. These present the Takasago Hydrogen Park project for the realization of ahydrogen society, the status of development of hydrogen/ammonia-fired gas turbines andhydrogen/ammonia engines, the technology for ammonia co-firing in coal-fired boilers, and thenuclear energy business that can realize a stable, carbon-free energy supply. Furthermore, “CO2capture, circulation and utilization” is indispensable in carbon neutrality. Presented in relation tothis topic are the large-scale carbon dioxide capture, utilization and storage (CCUS) and compact
CO2 capture systems, sustainable aviation fuel (SAF) that can help decarbonize the aviationindustry, and the recovery and recycling system of biomass resources in municipal waste.
The next set of reports focuses on the “Smart Infrastructure”, which pertains to the initiatives on
the energy use side. These include the projects about: decarbonization in the iron and steelmaking
sector; heat pump technology – the key to decarbonizing the industrial sector; smartification oflogistics; social infrastructure to support mobility; large-capacity electric compressors forair-conditioning systems in electric vehicles; advanced composite material technology to reduce theweight of future aircraft; and data centers with power-saving features that will be the foundation for
the next-generation social infrastructure. Also presented in relation to the projects undertaken withthe aim of “providing total solutions” for the smartification of social infrastructure are theMitsubishi Heavy Industries Technical Review Vol. 59 No.4 (December 2022)2

decarbonization of factories/works/plants as well as the energy management system for carbon
neutrality.
We appreciate your continued understanding and support for our activities.
