Sumitomo Electric Industries has announced the Mid-term Management Plan 2028, a three-year plan that positions digital & AI, energy, and mobility as key areas for the continued growth of the Sumitomo Electric Group. By investing a total of one trillion yen over the next three fiscal years in these key areas and related technologies, the Group will leverage its integrated capabilities to respond effectively to global changes and the demands of Green Transformation (GX) and Digital Transformation (DX).  Press release: https://lnkd.in/ePZ8Ktas Connect with Innovation | Sumitomo Electric 

We were delighted and honoured to welcome senior representatives from our valued customer, SSEN Transmission, to our factory construction site. It was a pleasure to present the strong progress being made and to exchange views on the project’s development. We sincerely appreciate their continued trust and partnership. As a local manufacturer, we are proud to support SSEN Transmission in delivering critical infrastructure for the region and remain committed to contributing to a reliable and sustainable energy future. We look forward to the next steps in our journey together.

As renewable energy adoption accelerates, one challenge is becoming increasingly clear: how do we store and deliver energy when it’s needed most? Sumitomo Electric will be exhibiting at #CLEANPOWER2026, showcasing our vanadium redox flow battery (VRFB) technology—designed to support long-duration energy storage (LDES) and grid reliability. With a proven track record in large-scale deployments, VRFB enables: • Safe, non-flammable operation • Long service life with stable performance • Long-duration energy storage (LDES) designed for grid-scale applications If you're attending CLEANPOWER, we invite you to connect with us and explore how energy storage can support renewable integration and grid stability. 📅 June 1–4, 2026 📍 George R.

In a new post, SEI President Inoue writes about the welcome ceremony for new employees that was held earlier this month: "As this fiscal year marks the first year of our Mid-term Management Plan 2028, we are at a new milestone in our corporate journey. It's my hope that everyone who has joined us will use this policy as a foundation to manifest their abilities to the fullest in their respective workplaces, as we all work together to build our company's future."

"Sumitomo Electric has a long history of turning familiar materials into high-performance products—such as copper into wires, glass into optical fibers, and iron powder into sintered components," notes Masato Baba, an assistant manager in our Advanced Materials Laboratory. Inspired by that tradition, he asked himself: What if carbon dioxide could be transformed into a functional material with industrial value?  This question led Baba-san to develop metacol™, a chemical process that uses iron, water, and CO2 to produce iron carbonate (FeCO3) and hydrogen gas. He says the iron carbonate can improve rigidity, heat dissipation, and flame resistance when mixed with resins. The company is now looking into various ways to use the substance to enhance the value of existing products.

Unlike Sumitomo Electric's businesses based on copper wire or optical fiber, the Special Steel Wire Division was founded on iron. Its main product, prestressed concrete (PC) strand, is a high-performance steel cable that's used to reinforce bridges, buildings, and expressways.  PC strand has also been augmented to enable infrastructure monitoring. "By integrating optical fibers into PC steel strand, [it can] detect ground movement via sensors," explained General Manager Kazuhiko Saiga in a recent interview.  Such integration of diverse technologies is just one way we continue to build "businesses that are necessary for society and trusted," said Saiga-san. He emphasizes the importance of adaptability and communication as well.  Read the interview: https://lnkd.in/e8DjgQpK Connect with Innovation | Sumitomo Electric

In a recent interview with the Nikkei financial newspaper, SEI President Osamu Inoue talked about the Sumitomo Electric Group's long-term growth strategy in general and one product in particular: the redox flow battery. This large-scale battery system, used by utility companies for long-duration storage of wind and solar power, is one of the major ways in which Sumitomo Electric is contributing to the infrastructure of renewable energy. The redox flow battery's safety, long operational life, and recyclability are highlighted in the article below.  Read the article: https://lnkd.in/edH5TxVC Connect with Innovation | Sumitomo Electric
