JGC and Yokogawa Team up to Develop Lunar Plant Control System
That Will Support Ultra-remote Communications
JGC Corporation and Yokogawa Electric Corporation (TOKYO: 6841) announce the signing of an agreementon November 15 to jointly develop a control system that will support the ultra-remote communications required
for the operation of plants on the lunar surface.
Initiatives aimed at exploring and developing the moon are already underway in many countries. For example,
the Artemis project, a US-led manned lunar exploration program, is proceeding in partnership with 32 countries,including Japan (as of December 4, 2023). In addition, the Japan Aerospace Exploration Agency (JAXA) is
considering a concept for a plant that will utilize water resources on the moon to produce hydrogen and oxygenfor use by spacecraft and manned facilities. Considering the possibility that such a plant might be built on thelunar surface, JGC and Yokogawa have decided to leverage their technology and experience in terrestrial plant
operation, remote monitoring, and control to research and develop the core underlying technology for a control
system that will support communications at extreme distances.
The construction of such a system, which will be located at a ground station and integrate the communications,process control, and operation monitoring for a plant on the lunar surface, will need to take into accountconstraints such as the communication delay between the earth and the moon. This joint development will makeuse of JGC’s know-how of energy plant control/operations and knowledge gained through the conduct of lunar
plant studies, and Yokogawa's remote monitoring and control technology. The two companies plan to quickly
move ahead with the design and construction of experimental equipment that can simulate these delays, thencomplete by the end of 2024 a study that will identify an optimal solution for a control system that will becapable of handling ultra-remote communications.
This joint development project will also look at whether this system can be utilized for plants and other facilities
here on Earth. The separation of the heart of the control system (the controller that executes the control logic)
from the equipment installed in the plant makes it possible to remotely control these plant facilities, giving plantowners greater flexibility in production planning and simplifying the task of plant maintenance.
JGC is actively engaged in lunar development activities. In April 2021, the company entered into an agreementwith JAXA to collaborate in a conceptual study of a plant on the lunar surface that will produce propellants, andin November 2021 joined a lunar development project that is being conducted under the Japanese government'sStardust program.
Yokogawa has positioned space as a new business area that it will explore, and in July 2021 launched a dedicated1

organization to develop the space business. In July 2023, Yokogawa and JAXA began a proof-of-concept studyof a water pipe network monitoring solution that uses data from the ALOS-2 satellite, and the company isworking on a wide range of business opportunities that will utilize space infrastructure for existing businesses.
