  • Satellites and Remote-sensing technology for Climate Change monitoring

    JAXA's efforts to understand sink and sources of Greenhouse Gases by satellites will be presented.

    JAXA began satellite Earth observation in the 1980s, and over the years has acquired data on the global environment, including land areas such as forests, which are sinks for GHGs; ocean areas such as polar sea ice and sea surface temperature; and the atmosphere such as carbon dioxide and methane.
    Currently, JAXA is operating six satellites. The satellite provide information using long-term, wide-area observation data, which is one of the satellite's features, and will contribute to providing scientific evidence in the Global Stocktake process. In addition, since the satellite conducts global observations, it will also provide scientific evidence on emissions in the realization of a "decarbonized society" in each country and region.

    Left:SAPCECOOL_Film / Right:SPACECOOL_Membrane

    SPACECOOL®, a zero-energy radiative sky cooling material, uses optical control technology to suppress heat input from sunlight while releasing heat into outer space through an atmospheric window, thereby maintaining temperatures below ambient air even under direct sunlight without consuming any energy. When used in living and transportation spaces, it reduces the environmental burden caused by air conditioning and creates comfortable spaces by controlling internal temperatures. In this exhibition, we are showing the effects of SPACECOOL as a measure against energy conservation and global warming, such as a 20% improvement in cooling efficiency in a prefab house, and propose solutions for "heat" using tents made of our materials and our products to prevent heat stroke.

  • Realization of CCUS with concrete&Energy- Generating exterior system

    Environmentally friendly concrete that carbon-negative & exterior system that achieves efficient solar power generation functions on the walls and windows.

    Carbon-Recycled Concrete: “T-eConcrete®/Carbon-Recycle” enables to take in a large amount of CO₂ and make the CO₂ balance of concrete negative.
    T-Green® Multi Solar See-through type offers daylighting with power generation Solid type offers outstanding design

    Our Carbon-Recycled Concrete, prepared with calcium carbonate produced by reacting calcium with CO₂ captured from the atmosphere and the exhaust gases as well as large amount of ground granulated blast furnace slag, an industrial by-product, has achieved carbon-negative.
    While this concrete maintains the same strength and workability as ordinary concrete, we have been able to prevent rebars from being corroded and to secure the durability of building structures, thus our Carbon-Recycled Concrete can contribute to the early realization of carbon neutrality.

    Buildings located in the urban metropolitan areas usually have small rooftop areas, and as a result the capacity of power generated by solar photovoltaic panels installed there is limited. On the other hand, we also have an issue that, from the design perspective, it is also limited to install solar photovoltaic panels onto large-scale facades of the buildings. Therefore, Taisei Corporation and Kaneka Corporation have jointly developed the building integrated photovoltaics panel "T-Green Multi Solar" with an excellence in design that can be installed on facades (window and wall surfaces) with great power generation potential, and we continue our contribution to the improvement of the Energy Generation of the buildings.

    Replacing fossil fuel engines with superconducting motors to power large mobility vehicles and boosting zero emissions!

    Lightweight, Compact, High-Power Superconducting Motor Prototype
    To achieve net zero in the aviation industry, not only SAF but also hydrogen fuel and electrification are essential.

    The mobility industry is accelerating moves toward CO₂ reductions. For instance, the aviation industry is looking at using sustainable aviation fuel (SAF) in order to become carbon neutral by 2050. But fuel alone is not enough. Aircraft systems as whole must evolve.

    Toshiba Group has applied its long-cultivated superconducting and manufacturing technologies to a high-speed rotating machine. The result is a prototype for the world's first lightweight, compact, high-power superconducting motor, with high-speed rotation and a maximum output of 2 MW. It is less than one-tenth the weight and size of a conventional motor. We will contribute to a carbon-neutral society by reducing the weight and accelerating efforts for implementation.
