[Japan] Kansai Electric Power Developed a Drone to Conduct Chimney Inspections for Thermal Power Plants

On August 6, 2020, Kansai Electric Power (KEPCO, Headquarters: Osaka Prefecture) announced that it has developed a drone that can be used to inspect the interiors of chimneys installed at thermal power plants.

Traditionally, workers had to set up a scaffold inside the chimney to inspect the interior to identify any deterioration. This work posed some significant risks for worker safety because the height of chimneys installed at thermal power plants can reach approximately 200m.

The use of drones was previously considered to be too difficult since Global Positioning System (GPS) is not available inside the chimney. However, the drone developed by KEPCO is equipped with Visual Simultaneous Localization and Mapping (SLAM), a mapping technology that can determine the position and orientation of the drone, as well as LiDAR, a method for measuring distances, in order to enable autonomous drone operation without GPS. It is the first time that Japan has developed a drone technology that can determine the position of a drone in a cylindrical space where GPS is not available.

In addition to improving worker safety, the drone is expected to reduce the time necessary to conduct inspections by approximately 90% and the inspection costs by more than 50%.

KEPCO partnered with Kanso (Headquarters: Osaka), a civil engineering consulting company, and Autonomous Control Systems Laboratory (Headquarters: Tokyo), an autonomous control solutions company, to consider marketing the drone to utilities and local governments.[1] [2]

[Japan] Japan’s Agency for Natural Resources and Energy Held a Discussion About Phasing Out Inefficient Coal-Fired Power Plants

On July 3, 2020, the Ministry of Economy, Trade, and Industry (METI) announced its plan to develop specific measures for phasing out inefficient coal-fired power plants by 2030. The announcement was made by Hiroshi Kajiyama, the minister of METI, in a press conference.

Japan’s decision to phase out inefficient coal-fired power plants is described in the 5th Strategic Energy Plan[1] issued in 2018; however, no detailed implementation plans were developed thus far. Minister Kajiyama described the need to develop concrete steps towards phasing out inefficient coal-fired power plants and accelerating the implementation of renewable energy to achieve a decarbonized society while carefully balancing Japan’s energy mix with consideration of limited energy resources to ensure a stable energy supply. The minister said that he had ordered METI’s officials to start discussion to develop the phase out plans by the end of July 2020.

Following this announcement, on July 13, 2020, the Agency for Natural Resources and Energy’s Electricity and Gas Industry Committee held a meeting to discuss specific measures to phase out coal-fired power plants.  The discussion focused on addressing the following topics:

1)   Introduce new regulatory measures in order to phase out inefficient coal-fired power plants

2)   Create new mechanisms to promote the early retirement of inefficient coal-fired power plants while ensuring a stable energy supply

3)   Review the current utilization rules on transmission lines to implement measures to accelerate the expansion of renewable energy, while considering various specific regional conditions.

Currently, coal-fired power generation accounts for 32 percent of Japan’s energy mix and inefficient coal-fired generation accounts for 16 percent of the total. Japan plans to reduce the share of coal-fired power generation to 26 percent by FY 2030. Japan plans to continue supporting the long-term use of coal generation by promoting innovative technologies to enhance the efficiency of coal-fired power plants, including Integrated Coal Gasification Combined Cycle (IGCC), Integrated Coal Gasification Fuel Cell Combined Cycle (IGFC), and Carbon Capture Utilization and Storage (CCUS).

[Japan] NEDO and the Advanced Hydrogen Energy Chain Association for Technology Development Jointly Conducted the World’s First Global Hydrogen Supply Chain Demonstration Project

On June 25, 2020, New Energy and Industrial Technology Development Organization (NEDO, Headquarters: Tokyo) and the Advanced Hydrogen Energy Chain Association for Technology Development (AHEAD, Headquarters: Yokohama City, Kanagawa Prefecture)[1] announced that they have conducted the world's first global hydrogen supply chain demonstration project, which transports hydrogen from Brunei Darussalam to Japan. NEDO is Japan’s largest public R&D funding organization specialized in innovative energy technologies. AHEAD was established in 2017 by four Japanese companies: global chemical engineering company Chiyoda (Headquarters: Yokomaha City, Kanagawa Prefecture)[2], Japanese shipping company Nippon Yusen (Headquarters: Tokyo)[3], and two Japanese trading companies, Mitsui & Co (Headquarters: Tokyo)[4] and Mitsubishi (Headquarters: Tokyo).[5] AHEAD is an association that supports hydrogen research in order to accelerate the development of hydrogen supply chains.

The project uses the "organic chemical hydride method" to build the hydrogen supply chain. Methylcyclohexane (MCH) generated in Brunei is transported by sea to Japan. The MCH is then separated into hydrogen and toluene at a dehydrogenation plant located in Kawasaki City, Kanagawa Prefecture. The toluene is then sent back to Brunei’s hydrogeneration plant and processed to re-bond with hydrogen.

The first MCH transportation process was carried out in December 2019. The dehydrogenation plant in Kawasaki City began extracting hydrogen from MCH in April 2020 and has been supplying hydrogen to the gas turbine of the Mizue power plant owned by Toa Oil (Headquarters: Kawasaki City, Kanagawa Prefecture) since May 2020.[6] In June 2020, the project began transporting the toluene processed by the Kawasaki dehydrogenation plant to Brunei. NEDO and the AHEAD will operate the demonstration test until the end of 2020 to evaluate the performance of the hydrogenation/dehydrogenation plant equipment and identify any issues.

NEDO has contributed to the development of hydrogen technology since FY2015. Through this project, NEDO intends to establish a large-scale hydrogen utilization system that can transport hydrogen from overseas and use it for Japan’s hydrogen power generation.[7]

[Japan] Tokyo Gas Invested in Floating Wind Power Company Principle Power

Tokyo Gas (Headquarters: Tokyo[1]) announced on May 27, 2020, that it has invested more than 2 billion yen (approximately $18 million)[2] in Principle Power (Headquarters: Emeryville, California, U.S.), a wind power technology developer that owns the WindFloat technology. With its investment, Tokyo Gas has become one of Principle Power’s major shareholders.

WindFloat is a patented technology owned by Principle Power. It is a floating foundation for offshore wind turbines. The technology has achieved high stability in various aquatic environments and is expected to be widely adopted by floating offshore wind projects around the world in the future. It has already been used in some large wind turbine projects in Europe. The introduction of WindFloat technology is expected to drive the implementation of floating offshore wind turbines in Japan, where the availability of shallow seabeds is limited.

Tokyo Gas has been investing in renewable energy sources in Japan and overseas to achieve net-zero CO2 emissions. According to its management vision, Compass 2030, it aims to reach 5GW of renewable power generation capacity by 2030. Investment in Principle Power’s technology is expected to further accelerate this effort.

Takeshi Uchida, President of Tokyo Gas, said, “Our company is working to build up renewable energy sources inside and outside of Japan in order to achieve net-zero CO2 emissions as set forth in our Group Management Vision, “Compass 2030.” Principle Power, with its advanced technology and proven track record in the field of floating offshore wind, which is expected to grow in Europe and in Asia, is an ideal partner for Tokyo Gas, and this investment will give us a good start in promoting floating-type wind power generation projects in Japan and in other parts of the world.” [3] [4]

[Japan] Toshiba Energy Systems & Solutions and Chubu Electric Power Announced the Construction of the Double-Flash Geothermal Power Plant in Gifu Prefecture

On May 13, 2020, Toshiba Energy Systems & Solutions (Headquarters: Kawasaki City, Kanagawa Prefecture) announced that Nakao Geothermal Power Generation Corporation (Nakao Geothermal, Headquarters: Takayama City, Gifu Prefecture) will build a double-flash geothermal power plant in Takayama City, Gifu Prefecture.[1] Nakao Geothermal was jointly established in 2013 by Toshiba Energy Systems & Solutions, a subsidiary of Toshiba (Headquarters: Tokyo)[2] that offers energy business products and services [3], and Cenergy, a subsidiary of Chubu Electric Power (Chuden, Headquarters: Nagoya City, Aichi Prefecture). Toshiba Energy Systems & Solutions owns 55 percent of shares of Nakao Geothermal, and Chuden owns 45 percent of share of it.

The construction of the Nakao Geothermal Power Plant is scheduled to begin in September 2020, and it is expected to begin commercial operations in late 2021. It is the first time for Toshiba and Chuden to cooperate to build a geothermal power plant. The maximum capacity of the power plant is expected to be 1,998 kW, and all of the generated electricity will be sold to Chubu Electric Power Grid (Chuden Power Grid, Headquarters: Nagoya City, Aichi Prefecture)[4] to supply approximately 4,000 households.

The plant will adopt the double-flash method, which is about 20% more efficient than the general single flash method. It will be the world’s smallest geothermal power plant using this method. The Okuhida Onsengo Nakao district where the plant will be constructed is famous for its hot springs and the hot temperature of its steam, which makes it suitable for geothermal generation.[5]
