- Showcasing Energy Technologies Contributing to Carbon Neutrality SCiB, AEROXIA and P2C (Power to Chemicals) -

TOKYO, Nov. 27, 2023 /PRNewswire/ -- Toshiba Corporation and Toshiba Energy Systems & Solutions Corporation (hereinafter "Toshiba ESS") will be exhibiting innovating technologies at the Japan Pavilion, the exhibition accompanying the 28th Conference of the Parties to the United Nations Framework Convention on Climate Change ("COP28") in Dubai, UAE, from November 30 to December 12. Toshiba and Toshiba ESS will exhibit cutting-edge technologies—SCiB, AEROXIA and P2C (power to chemicals)—that are contributing to the global goal of achieving carbon neutrality.

The Japan Pavilion at COP28, organized by Ministry of the Environment, Government of Japan ("MOE"), will serve as an exhibition and event space, a showcase for Japan's outstanding products, services, and initiatives in the global effort to address climate change.

Toshiba Group will exhibit energy solutions that play a crucial role in achieving carbon neutrality across the energy lifecycle – from generation and transmission to storage and smart-use. The Toshiba technologies the MOE has selected to showcase include SCiB, complemented by AEROXIA and P2C.

Exhibition Highlights:

1. Energy Storage and Smart-use: SCiB Optimizes Battery Systems from a Product Lifecycle Perspective

The SCiB, the lithium-ion rechargeable battery developed by Toshiba, offers performance characteristics that overcome challenges for conventional batteries. These include a long life of over 20,000*¹ charge and discharge cycles, rapid charging, high input and output performance, excellent low-temperature performance, and wide state-of-charge*² range, all while maintaining a high level of safety.

The excellent performance of the SCiB supports an extended lifetime, which contributes to lower consumption of limited resources such as lithium and reduces the total cost throughout the lifecycle of battery systems. The effects lead to co-benefits*³, supporting a circular economy and fostering nature positive*⁴. Models of SCiB cells and SCiB modules will be on display at the Japan Pavilion.

2. Energy Transmission: AEROXIA Replaces SF₆ in Power Facilities with Eco-friendly Gas

The excellent high-voltage insulation and current interrupting capabilities of sulfur hexafluoride (SF₆) has won its wide use in gas-insulated switchgear, where it significantly contributes to compact design and easy maintenance. However, released into the atmosphere, it is over 20,000 more effective at trapping heat than the equivalent volume of CO₂. These environmental concerns are behind legislative initiatives to prohibit its use in the EU and at the federal and state level in the United States.

Toshiba ESS prioritizes a product philosophy that integrates high safety, environmental sustainability, and user-friendliness. In 2022, with a dedication to environmental harmony and seek to heighten maintenance efficiency, Toshiba ESS introduced AEROXIA*⁵, which serves as an SF₆ alternative solution for electrical power facilities, entirely eliminating the use of SF₆ and utilizing natural-origin gas as an alternative. The product lineup continues to expand, showcasing a range of environmentally friendly and easily maintainable solutions. At the Japan Pavilion, AEROXIA will be introduced through video presentations.

3. Smart-use of Energy: P2C (Power to Chemicals) that Transforms CO₂ into Green Resources with Renewable Energy

Achieving carbon neutrality requires the effective utilization of CO₂ as an asset. P2C, powered by renewable energy, transforms CO₂ into valuable resources, such as synthetic fuels and chemicals. Toshiba Group has developed a CO₂ electrolysis system based on artificial photosynthesis technology that converts CO₂ into CO, a raw material for chemical products, with the world's highest conversion rate*⁶.

On the basis of that success, Toshiba Group along with other partner companies, was commissioned by the MOE to conduct "Project to Promote the Creation of Circular Carbon Society Model through CO₂ Recycling (Regional CO₂ Resource Utilization Study Business Through Electrolysis Utilizing Artificial Photosynthesis Technology)" (2021-2024). The Group has produced a prototype, "C2One", that stacks over 100 cells, and that can process 250 tons of CO₂ a year and will conduct an operational demonstration of its capabilities. At the Japan Pavilion, the concept of P2C and its contribution to society will be introduced in a video.

Guided by its corporate philosophy, "Committed to People, Committed to the Future.," Toshiba Group contributes to society with products and services that support us in our daily lives and address societal challenges. The adoption of the Paris Agreement in 2015 has accelerated global initiatives toward carbon neutrality, and inspired companies to proactively address the long-term impacts of climate change. Toshiba Group is responding to this challenge by actively applying its advanced technologies to the realization of global objectives, such as carbon neutrality and a circular economy.
