Welcome to this special edition of our technical review featuring Plants & Infrastructure Systems.
Global warming is one of the critical environmental issues that the world should unite to solve.
The importance of initiatives to achieve a carbon-neutral society with net-zero emissions ofgreenhouse gases (GHGs) is increasing day by day. With IT and digital technologies developing
dramatically, there is a growing need from society and customers in all business fields for theproducts and services to be automated, manpower saving and become infallible even without skill.
This edition introduces our latest products and developments in Plants & Infrastructure Systems,
which aims to contribute to a sustainably growing world while responding to environmental issues
and social needs.
Presented in the commercial ships business are: the solution technologies necessary to achieve
zero emissions from vessels, which is underway under the International Maritime Organization’s(IMO’s) target of carbon net zero by 2050; the product development of gas handling technology; theLNG-fueled ferry “Sunflower Kurenai” and the liquefied CO2 carrier “EXCOOL,” which serves asa safe and inexpensive means of CO2 transportation in the Carbon dioxide Capture, Utilization andStorage (CCUS) value chain.
In the metals machinery business, we are expanding our product lineup to meet the industry’s
decarbonization needs of the metal machinery industry, which is called the “hard-to-abate” industry
because of the difficulty to reduce CO2 emissions, Following the previously introduced technology
related to the hydrogen-based direct reduction of iron ore, this edition presents the technologies thatare indispensable to Green Steel project. That is, active power feeder system for feeding electric
furnaces, and the endless hot rolled coils in which original thermal energy of the liquid steel is usedinstead of fossil fuel to reduce GHG emissions.
The demonstration of CO2 capture from flue gas of waste incineration facility for use inmethanation, and the Hybrid Bag Filter® made of Polytetrafluoroethylene, for waste incineration
plants are described in relation to the environmental systems business whose goal is to achieve a
resource circular society.
In addition, related to machinery systems business, the reports pertain to: the manufacturing
technology of accelerating cavities in the electron accelerator for the synchrotron radiation facility
that works as a tool to develop new materials and unravel microscopic phenomena or those occurring

within an extremely short time; our initiatives to enable autonomous buses to become part of mobility
services to build a safe and secure social infrastructure; and the sequel to the previously introduced
Facility Engineering.
Lastly, presented in addition to the electric propulsion system to electrify ocean mobility are thesystem development cases in which DX is utilized in such a way that it can set off a great change insociety. These include: the integrity management system using digital twin for large floating
structures; the reinforcement learning-based control technology to stabilize fuel supply to the stoker
furnace; and the ride experience system to evaluate comfort of automated guideway transit using VRtechnology.
Plants & Infrastructure Systems will continue its journey to achieving a carbon-neutral society
and building safe and secure social infrastructure through providing wide range of products andservices by leveraging the strengths of each business. We appreciate your continued support.
