[Case 1] Hydrogen solution

Toshiba Energy Systems & Solutions Corporation

In response to the trend toward low-carbonization and de-carbonization that is underway around the world following the Paris Agreement, Japan has also set the goal of reducing CO2 emissions 80% by 2050 and is working to introduce renewable energy nationwide. To solve this challenge, however, a new technology such as the hydrogen solution needs to be introduced due to issues including a decline in the operating rate of renewable energy due to increased restrictions on connection to the power grid and additional implementation of output control, increased investment in batteries by renewable power generation operators and power transmission and distribution operators, and a drop in the operating rate of thermal power plants to adjust the power supply.
The hydrogen solution utilizes power storage capability to cope with unstable renewable energy, and also can convert renewable energy power into hydrogen for multiple purposes. By taking advantage of these characteristics, we provide two solutions: "off-grid power supply using hydrogen energy storage" and "hydrogen supply chain aimed at wide area use."
As an off-grid power supply, we have the H2One™ hydrogen-based autonomous energy supply system, which has been installed in local government offices, baseball parks, beer factory tour facilities, and so on. In addition, our H2Rex™ pure hydrogen fuel cell system has also been installed in factories, markets, hotels, and so on and further success in the installation of the system is expected.
As a representative case of the hydrogen power-to-gas (P2G) supply chain*, Fukushima Hydrogen Energy Research Field (FH2R) is being constructed in Namie-machi, Fukushima in Japan. This research is a project assigned to Japan's New Energy and Industrial Technology Development Organization (NEDO), and the world's largest class water electrolyzer is used to produce hydrogen. The demonstration operation and hydrogen transportation are planned to commence by July 2020 and the hydrogen produced in the FH2HR will also be used for the 2020 Tokyo Olympics and Paralympics.

[Case 2] Recycling of carbon dioxide using renewable energy

Toshiba Corporation
Corporate Research & Development Center

Among the efforts for the elimination of the increasing CO2 emissions in Japan, CO2 reduction in the industrial sector, including factories, has also become a major issue. To deal with this situation, CO2 is effectively used by converting it into valuable products via a technology in which chemical reactions and electricity are involved (electrochemical reactions).
We have been developing such a carbon dioxide recycling technology to produce green chemical products such as methanol from renewable energy and carbon dioxide by using our unique catalyst electrodes. Recently, we have successfully developed a CO2 recycling cell with drastically improved CO2 conversion rates, enabling a substantially reduced CO2-recycling system installation area. Using this technology, we will reduce carbon dioxide emissions more economically and contribute to achieving a de-carbonized society.
We are conducting a system demonstration of this technology and will construct a model carbon recycling society via the "Carbon Dioxide Recycling Model Project using Artificial Photosynthesis Technology," a project commissioned from the Ministry of the Environment, with the aim of putting the technology into practical use in the late 2020s.

[Case 3] Perovskite film-based solar cell

Toshiba Corporation
Corporate Research & Development Center

We have developed the world’s largest film-based perovskite*1 photovoltaic module, which are expected to help reduce costs and achieve high efficiency due to the use of the printing technology. With a newly developed process, in addition to our unique printing technology, we have achieved both the world’s largest*2 area of 703 cm2 and high energy conversion efficiency of 11.7%, although coexistence of large area and high efficiency is difficult. Due to their flexibility and lightweight, the film-based perovskite photovoltaic modules can be installed in many installation situations, including installation in buildings with low load bearing capacity and on walls, in which hard crystal Si solar cells could not be installed previously, and these will lead to the spread of zero energy buildings.
These results have been obtained by "Development of technology of power generation cost reduction for high-performance and high-reliability solar power generation," project commissioned from Japan's New Energy and Industrial Technology Development Organization (NEDO).

[Case 4] AI technology for accurate forecasting of power demand and solar power output

Toshiba Corporation
Corporate Research & Development Center

Electric utility companies usually operate power stations while forecasting the amount of power that will be needed. Since a power shortage may cause a serious accident such as a major power outage, stand-by operation of thermal power stations is performed so as to immediately respond to power demand that exceeds the forecast. If the forecast is accurate, unnecessary stand-by operation will no longer be needed thus resulting in improved power generation efficiency and therefore a reduction in CO2 emissions. To achieve this we will apply AI in a system to accurately forecast power demand and solar power output.
Power demand and solar power generation are largely dependent on weather conditions. Therefore, by teaching AI weather conditions such as temperature and the amount of solar radiation that affect power demand and solar power output, we improved the accuracy needed to forecast future power demand and solar power output. We participated in the “First Electricity Load Forecasting Technology Contest” hosted by Tokyo Electric Power Company Holdings (TEPCO) and the “PV in HOKKAIDO Contest on Technology for Predicting Solar Energy Production” jointly hosted by TEPCO and Hokkaido Electric Power and received both best award and grand prize. Looking forward from here, we will aim to introduce a system to support utility companies in operating efficiently in anticipation of renewable energy to serve as a major power source.

[Case 6] Toshiba machine-room-less elevator SPACEL-GR Ⅱ

Toshiba Elevator and Building Systems Corporation

The SPACEL-GR Ⅱ is an elevator developed with the aim of improving ride safety, security, and comfort. Equipped for the first time in the industry with a feature to eliminate the gap between the elevator and the building when passengers get on and off the elevator, the SPACEL-GR Ⅱ prevents accidents caused for example by a cane or shoe caught in the gap or dropped items. In addition, by grasping the movement of people around the elevator using advanced image analysis technology, it efficiently opens and closes the door and prevents a passenger from becoming caught there.
In terms of environment, while reducing power consumption by up to 50%* through the use of regenerative electric power and adoption of LED lighting, as well as by reducing stand-by current with a controller and improving system efficiency, it also reduces hazardous substances by use of the following: guide rails needing no lubrication through use of a roller guide shoe, by reducing the lead content, and adopting mercury-free LED lighting, and use of non-vinyl chloride decorated steel plates.

[Case 7] Spot and zone air-conditioning system "FLEXAIR"

Toshiba Carrier Corporation

In addition to energy saving performance, air-conditioning a large space such as a warehouse, exhibition hall, and factory, requires high efficiency products to deal with issues in installation restrictions, environmental improvement effects, and others. To accomplish this, we worked to develop a product that does not require a ceiling duct, can effectively use columns and wall surfaces as the installation locations, and can create more appropriate air-conditioning environment based on high-speed airflow control for each spot and zone requiring air-conditioning while maintaining excellent energy saving performance and have completed the spot and zone air-conditioning system "FLEXAIR."
This product features an annual performance factor (APF) of 4.86 and can reduce the power consumption per period by as much as 26% when compared with the floor installation, direct blowing type* used in many workplaces and the like. These factors were highly rated and the product received the METI Minister's Award in the FY2018 Energy Conservation Grand Prize.

[Case 8] LED high-bay lighting fixture (lightweight type)

Toshiba Lighting & Technology Corporation

Conventionally high-bay lighting fixtures had been assembled with HID lamps*1 (hereafter, conventional fixture) and were used at large space facilities such as arenas, gymnasiums, factories, and warehouses. The conventional fixture has generally been used in between the luminous flux range of 1 kW metal halide lamp (96,000 lm total luminous flux*2 at 1,050 W rated wattage) and of 250 W metal halide lamp (22,000 lm total luminous flux at 275 W rated wattage).
However, in accordance with the implementation of the planned electric outage consequent upon the Great East Japan Earthquake, conventional fixtures which have inefficient energy consumption have been rapidly replaced with high efficiency LED high-bay lighting fixtures. Also, it is required to reduce weight load on ceiling for the prevention of damages caused by the possible next severe earthquake, when the existing buildings are repaired and the aseismic capacity are improved. In the view of this situation, we have developed LEDJ-21001N-LD9 LED high-bay lighting fixture (lightweight type) featuring both high efficiency and light weight. As a result, we have achieved approximately 62% lighter weight and around 4.3 times higher efficiency compared to the conventional fixture equivalent to a 400 W metal halide lamp.
This product was awarded the Energy Conservation Center, Japan Chairman's Award in the FY2018 Energy Conservation Grand Prize.

[Case 9] Structure health monitoring using AE sensing

Toshiba Corporation
Corporate Research & Development Center

The market scale for infrastructure maintenance and management technology is expected to reach approximately 700 billion yen in 2030. As for 25% of the domestic bridges over 2-meter length, more than 50 years has passed since they were built by 2018, and also 68% of them by 2033. Under these circumstances, more efficient technology is newly required that takes place of conventional technique such as visual and hammering inspections. Toshiba has developed new monitoring system that is made to realize preventive maintenance by sensing the progressive damage of structures. The system detects Acoustic Emission (AE)*1 generated from inside structural components, like micro crack, wear, and flake, enabling us to detect internal damages that may cause massive destruction.
Now we are targeting at Reinforced Concrete (RC) deck of a highway bridge. AE sensors are installed on the surface of the bottom panel, and AE waves generated from internal cracks in concrete are detected on passage of the vehicles. AE signals are sent to distant server via palm-sized wireless sensing units and accumulated. The signals are analyzed with our original signal processing technique in order to visualize the location and the scale of the cracks. Through the long-term verification test at the public highway bridge, we have good prospects of detecting the internal cracks.

[Case 12] Electronic receipt service SMART RECEIPT

Toshiba Tec Corporation

SMART RECEIPT is a system that digitizes receipts that customers receive when they make purchases at a cash register and manages and provides these receipts as data from SMART RECEIPT Center. While customers can check their shopping histories anytime and anywhere via smartphones, stores can improve the efficiency of cash register tasks performed by their employees, and eliminate the cost of issuing paper-based receipts. In addition, promotion services such as paper-based receipt coupons and stamp cards can be digitized thus reducing the operational cost as in the case of receipts.
The volume of receipt paper consumed in Japan in one year amounts to approximately 5.4 tons which corresponds to as many as 13.5 billion sheets of A4 copy paper.* Reducing the amount of receipt paper through SMART RECEIPT will contribute to reducing paper resources wasted after receiving such receipts as well as lead to reducing CO2 emissions and the amount of water used associated with manufacture of paper. Furthermore, reducing receipt paper can reduce the amount of pulp used, which will control the harvesting of forest resources, the raw material for receipt paper, and thus lead to protection of precious forest resources.
