Contributions to Society

Contribution to the SDGs through Our Business Activities

The Sustainable Development Goals (SDGs) express priority global issues and the ideal status of global society in relation to economics, society, and the environment in the lead-up to 2030. Many countries, companies, and other organizations are actively addressing these issues with the aim of creating sustainable societies.

The GS Yuasa Group believes that it can contribute to achieving the society sought by the SDGs by practicing our corporate philosophy of contributing to people, society, and the global environment through innovation and growth of our employees and business entities. The Group is developing globally with storage batteries as its main products, and by providing products and services to regional societies in every country of the world by making use of the storage battery technologies we have accumulated through more than a century of experience, we are working to solve the shared problems of the international community. In addition, the Group has decided to consider CSR issues that have an impact on its business as well as a significant impact on society, as materiality. By promoting activities that respond to materiality, we aim to maximize the positive impact and minimize the negative impact on global social issues.

Contributions to R&D Relating to Space Development Applications

The Group’s space lithium-ion batteries are used on the International Space Station (ISS). The ISS is a manned test facility constructed approximately 400 km above the Earth’s surface. It is used through the cooperation of many countries.

The main objective of the ISS is scientific and technological advances through various experiments and research in outer space, and the results of research, experimentation, and measurement are contributing to enriching lifestyles and enhancing industrial competitiveness. It is a key facility for making significant advances in space development and is also a symbol of international cooperation and peace operated jointly through the provision of state-of-the-art technologies by numerous countries.*

Power for all equipment on the ISS including experimentation and observation devices and life support systems is supplied by photovoltaic power generation. However, power generation ceases 16 times each day as the ISS passes through the earth’s shadow, and during these periods, power is supplied by GS Yuasa lithium-ion batteries for space use that are charged while the station is in the sunlight.

The GS Yuasa Group will continue contributing to the development of science and technology for the realization of a sustainable society through development and manufacture of high-performance lithium-ion batteries.

In Indonesia, where natural disasters (such as earthquakes, tsunamis, and floods) are many, disaster management activities carried out by the Karawang fire brigades play a very important role. PTGS assist the fire brigades in their smooth operations through the continuous supply of storage batteries. In fiscal 2022, in addition to donations to other public institutions, PTGS provided 108 storage batteries free of charge.

Inci GS Yuasa Aku Sanayi ve Ticaret Anonim Sirketi (below, IGYA), located in the Republic of Turkey, ensures a continued supply of storage batteries manufactured by our company to all vehicles owned by Turkey's largest search and rescue organization (AKUT), and has donated a total of 91 storage batteries since fiscal 2019. IGYA has also received training in fire, search and rescue, and disaster preparedness from the same organization in order to prepare for the establishment of an in-house rescue team. In February 2023, the company donated supplies, including tents and containers to be used for accommodation, basic toilets, heaters, hygiene kits, and winter clothing, along with 300 storage batteries needed for energy systems, to support those affected by the major earthquake which had occurred in south-eastern Turkey.

Siam GS Battery, located in Thailand has donated our company manufactured storage batteries to the Thung Yai Naresuan Wildlife Sanctuary and Border Patrol in Kanchanaburi Province. The Thung Yai Naresuan Wildlife Sanctuary is one of Southeast Asia’s largest wildlife reserves endowed with untouched nature and is also a UNESCO World Heritage Site. The donated storage batteries are used in solar power generation systems providing support to daily power use.

Stable Supply of Photovoltaic Generation Systems

A photovoltaic generation system using the GS Yuasa Group's lithium-ion batteries has been in operation at the Kushiro Town Toritoushi Wildland Photovoltaic Generation Plant in Hokkaido.

When generating photovoltaic power, changes in natural conditions, such as sunshine hours and temperature, can lead to significant fluctuations in the power generated, while a major increase in the photovoltaic power load could reduce the quality of the system's power in terms of both voltage and frequency. For this reason, storage battery systems are necessary to stabilize output fluctuations in power generated when photovoltaic power generating facilities are connected to the power grid.

In conjunction with the global increase in energy demand due to the growing population, economic growth and other factors, there are increasing calls for the expanded use of renewable energy as an alternative to limited fossil fuels. The introduction of storage battery systems to stabilize output fluctuations is essential for the effective use of energy from photovoltaic or wind power generation.

The Group continues to promote the use of high-performance lithium-ion battery systems in power generation and is aiming to contribute to creating sustainable local communities using renewable energy.

Contributing to the Optimization of Energy Use

The Group aims to optimize energy use in local communities by utilizing new energy services that link storage batteries with IoT technology.

At the Kyoto Plant, we have introduced a power storage system manufactured by our company that can handle virtual power plants* (below, VPP) and that performs energy management taking into account the balance between power supply and demand. By adjusting the power supply balance in the plant during normal times and utilizing it for peak cut in the event of tight demand, we have been able to achieve stabilization of power supply and lower power consumption costs. In addition, in the event of an emergency such as a power outage due to a large-scale disaster, supplying power in cooperation with solar power generation systems to lighting load (lighting and outlet equipment) and power load (air conditioning equipment) has also played a role in ensuring employee safety and business continuity.

Since fiscal 2016, the Group has participated in the VPP construction verification project to start verification of the introduction and control of large storage batteries. In fiscal 2017, we introduced a container-type power storage system at our Kyoto Plant and are promoting verification for the practical application of power supply and demand adjustments based on directives from external, large storage battery servers.

It functions like a single power plant through the supervision and control of scattered energy sources (including small-scale solar power generation and storage batteries) using IoT devices, and plays the role of adjusting the power supply-demand balance (including leveling the power load, absorbing surplus power when excess renewable energy is supplied, power supply in the event of power shortage).

Increasing the Accuracy of Greenhouse Gas Observations

The IBUKI-2 greenhouse gases observing satellite launched from the Tanegashima Space Center in October 2018 was equipped with a space lithium-ion battery manufactured by the Group. The mission of IBUKI-2 is to accurately and uniformly measure greenhouse gases such as carbon dioxide and methane around the world and to increase the precision of measurements.

Many countries are obligated to report on their own greenhouse gas emissions in accordance with the Paris Agreement, in international mechanism relating to climate change. As a result, the data obtained from IBUKI-2, which can take uniform measurements around the world, is expected to play an important role as a scientific basis for confirming the accuracy of greenhouse gas emissions volumes by each country.*

Group products will continue to contribute to international efforts to curtail global warming.
