  • SCiB™ optimizes battery systems from a product lifecycle perspective

    "Generation", “Transmission", "Storage", and "Smart-use". Toshiba's total energy solution that contributes to a carbon-neutral society

    From power generation to transmission and distribution, energy storage, energy conservation, and effective use, we ensure a stable energy supply as well as reduce greenhouse gas emissions in every corner of society.
    Applying advantages of high safety, long life and rapid charging to EV bus case, the number of buses and battery capacity can be reduced. Consequently, "larger cabins" and "improved energy consumption costs through weight reduction" are realized.

    A carbon-neutral society requires diverse technologies. Toshiba provides a full lineup of energy solutions from upstream to downstream.

    Regarding transmission and distribution networks, we have released AEROXIA™, an environmentally friendly, safe, and secure power facility that uses natural-origin gas instead of SF6 (sulfur hexafluoride) gas which has a very strong greenhouse effect.
    Regarding storage and smart-use of energy, rechargeable battery SCiB™ using lithium titanium oxide (LTO) in its anode, which is unique from conventional lithium-ion batteries, has excellent characteristics such as high safety, long life and rapid charging, optimizing the lifecycle cost through efficient use of energy.
    Furthermore, P2C (Power to Chemicals) is a technology to convert CO2 into resources, and produces synthetic fuels and chemical products without using fossil feedstock.

    Toshiba contributes to the realization of a carbon-neutral society through total energy solutions.

    Decarbonization solutions by MHI Group's CCUS value chain

    Contributing to carbon neutrality through MHI's strength ~CO₂ Capture, LCO₂ Carrier, CO₂ Compressor, etc.~

    Mission Net Zero:MHI Group's Declaration to achieve Carbon Neutral by 2040
    MHI Group's CCUS value chain

    To achieve decarbonized society, it is necessary to have both "CO₂ reduction" and "CO₂ recovery" activities. Even if CO₂ emissions are reduced in various ways, there are industrial sectors where CO₂ emissions are inevitable in order to continue economic and social activities. To recover CO₂ in these sectors, it is necessary to capture, transportation, recycle, and storage emitted CO₂ (CCUS). Mitsubishi Heavy Industries Group has a wide range of products and services that make up CCUS, such as CO₂ Capture System, CO₂ Liquefaction System, Liquefied CO₂ Carrier, and CO₂ Compressor. Through the provision of these decarbonization solutions, we will contribute to the early realization of carbon neutrality by establishing CCUS value chain.

  • High-efficient inverter air conditioners which contribute to 50% energy savings

    Inverter technology offers significant energy savings for air conditioners, which use 10% of the world's electricity.

    Approximately 10% of all electricity in the world is consumed by air conditioners.
    *Our calculation based on IEA/UNEP "Cooling Emissions and Policy Synthesis Report”
    By precisely controlling the compressor, the heart of an air conditioner. air conditioners equipped with inverters can achieve both a significant reduction in power consumption and comfort.

    The G7 and G20 highlighted the importance of enhanced energy efficiency as the “first fuel” to achieve net-zero emissions by 2050 at the latest. Currently, Air Conditioners(AC) account for about 10% of the world’s total electricity demand, but development in emerging countries has been increasing energy demand for AC on average 4% per year. High-efficient inverter AC precisely controls the rotation speed of the air conditioner compressor in line with ambient conditions to reduce power consumption. While the ratio of inverter AC has reached nearly 100% in markets such as Japan and Europe, such levels are still low in the whole world. Through this exhibition, we will introduce you of the potential of inverter AC for decarbonization and the advantages of Daikin's high-efficient inverter AC.

  • Decarbonization by Local SDGs
    San Pou Yoshi = Win-Win for All

    Biogas project addresses local challenges by resource circulation on Nature-based Solutions with "Together for Action"

    We tackle to creating a sustainable cycle of resources and energy in local towns based on Nature-based Solutions. This approach can be applied anywhere in the world as a local SDGs.
    We developed low-moisture methane fermentation process and plant which is simplified with automotive manufacturing know-how.

    The decarbonization in the industrial sector triggered "Together for Action". The local main industries, crops and livestock farmers, and the automobile industry, each have their own challenges: organic farming of Omi Rice, waste management of Omi cattle dung, and decarbonization of high-temperature heating.

    • The automobile industry processes Omi cattle dung into biogas and compost, and the gas is burned in a furnace.
    • Crops farmers use the compost to produce organic Omi Rice.
    • Livestock farmers use the Omi Rice straw to feed Omi cattle.
    • This sustainable cycle of resources creates a Nature-based solution to each of challenges.
    • Collaboration between local government and local industries helps to achieve SDG No. 17.
    • Local SDGs, "San Pou Yoshi" is a principle that can be applied globally.

  • "RePEaT PROCESS" for PET Chemical Recycling

    RePEaT PROCESS performs de-polymerization and purification of PET, which enables production of virgin equivalent PET

    RePEaT PROCESS Flow Scheme
    Concept for implementation of RePEaT Process

    Polyester (PET) is one of the major polymer which has been used widely, such as, plastic bottle, food package, fiber and film. RePEaT PROCESS de-composes the PET into minimum molecule unit, called monomer, then performs purification. These process enables removal of impurities and dye staff contained in the feedstock, and therefore, it is possible to produce virgin equivalent R-PET. RePEaT PROCESS is commercially proven and will contributes to reduce the fossil resource consumption because the process is useful to recycle products which are difficult to handle by mechanical recycling due to the impurities and its color.
    JGC group provides the RePEaT PROCESS all over the world as a license package through the joint venture company RePEaT Co., Ltd. founded by JGC HD, TEIJIN and ITOCHU.

  • Digital Transformation to accelerate Adaptation Finance for Climate Change

    Quantitatively assess the validity of disaster mitigation and the environmental value of disaster preparation to respond to intensify disasters, to encourage the flow of private sector funds into adaptation

    Overview of Adaptation Finance for Climate Change
    ~ Assessment of climate change risk, effectiveness of disaster prevention measures, and disaster mitigation value ~
    Creating Value through Digital Transformation of Adaptation Finance
    ~ Creating value in disaster mitigation by implementing disaster prevention solutions ~

    To achieve carbon neutrality, it's important to control CO2 emissions generated as a result of disaster recovery. To this end, it's desirable to increase the inflow of not only public funds but also private-sector funds to promote the adaptation projects to cope with extreme weather. Therefore, we'll create and globally disseminate "Digital Transformation to accelerate Adaptation Finance for Climate Change," a financial scheme to attract private-sector funds for adaptation projects, based on the advanced efforts and disaster prevention solutions of Japan, a disaster-prone country. Specifically, we'll create a mechanism to visualize the disaster prevention and environmental value of adaptation projects prior to their introduction by utilizing wide-area sensing technology, digital twin technology, etc., and convert them into economic value (premium) that is attractive to investors.
