[Japan] Kansai Electric Power, Kawasaki Heavy Industries, and RITE Agreed to Build a Test Facility to Conduct CO2 Capture Demonstration Project

On September 24, 2020, Kansai Electric Power (KEPCO, Headquarters: Osaka Prefecture); Kawasaki Heavy Industries (KHI, Headquarters: Tokyo)[1], a heavy machinery manufacturer; and the Research Institute of Innovative Technology for the Earth (RITE, Headquarters: Kyoto), a research institution that develops carbon dioxide capture and storage technologies[2], announced that they had reached an agreement to conduct a joint study on “Applicability to Capture Gas Generated by Coal Combustion using CO2 Solid Sorbents.”

KHI and RITE will work with KEPCO to build a pilot-scale test facility with a CO2 capture capacity of 40t-CO/day at KEPCO’s Maizuru coal-fired power plant to conduct the demonstration project. They were selected and financially supported by the New Energy and Industrial Technology Development Organization (NEDO, Headquarters: Tokyo), a Japan-based public funding organization that promotes the development and deployment of new clean energy technologies. The project marks the first demonstration test in Japan using solid sorbents for CO2 separation and capture at a thermal power plant. The method has the potential to significantly reduce the energy required for CO2 separation compared with conventional technologies.

The test facility is expected to begin the CO2 capture demonstration test in FY2022. KHI will be responsible for designing and constructing the test facility and conducting the CO2 capture and recovery test. KHI and RITE have been developing a solid absorber and a Kawasaki CO2 Capture (KCC) system for separating and recovering CO2 under the Carbon Dioxide Recovery Technology Practical Use Research Project, which was commissioned by the Ministry of Economy, Trade and Industry (METI) in FY2015. Since 2016, KEPCO has been collaborating with them toward the implementation of a pilot-scale tests to evaluate the durability and economic feasibility for solid sorbents at the Maizuru coal-fired power plant.

By leveraging the knowledge developed through the efforts of KEPCO’s engineering services branch, the Kansai-Value Creation Service (K-VaCS), KEPCO hopes to continue to contribute to the reduction of CO2 emissions and move towards a low-carbon society.[3] [4]

[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]

[USA] PSEG to explore strategic alternatives for its non-nuclear fleet

During its second quarter earnings conference call on July 31, 2020, New Jersey utility Public Service Enterprise Group (PSEG) announced that it is “exploring strategic alternatives” to PSEG Power’s, a subsidiary of PSEG, non-nuclear generating fleet.[1] This includes 6,750 MW of fossil generation located in New Jersey, Connecticut, New York and Maryland and its 467 MW Solar Source portfolio spread across 14 states. According to CEO Ralph Izzo, PSEG expects the sale of its fossil fuel portfolio to begin in late 2020 and be completed in 2021. PSEG intends to retain ownership of PSEG Power’s existing nuclear fleet. Izzo said the move to exit merchant generation while retaining nuclear power “could reduce overall business risk and earnings volatility, improve our credit profile and enhance an already compelling [environmental, social and governance] position driven by pending clean energy investments, methane reduction and zero-carbon generation.” In addition to keeping its existing nuclear fleet, PSEG says that it is evaluating potential investments in offshore wind and considering participation in upcoming offshore wind solicitations in New Jersey and other Mid-Atlantic states. The utility expects to decide on whether to invest in Ørsted's Ocean Wind project by the end of 2020.

[USA] Report: APS declares thermal runaway event caused 2019 battery explosion

According to a report released on July 27, 2020, an explosion on April 19, 2019 at Arizona Public Service’s (APS) McMicken Battery Energy Storage System (BESS) facility in Surprise, Arizona was caused by an internal cell failure in a single battery which led to a cascading thermal runaway event[1].[2] The report was written for APS by Davion Hill, a U.S. energy storage leader DNV GL, a Norway-based company that provides advisory and analytics services to the energy industry. The report found that abnormal lithium metal deposits likely led to the internal failure. Contributing factors to the explosion include: a lack of thermal barriers between battery cells, a fire suppression system ill equipped to stop the thermal runaway, a concentration of flammable off-gassing, and a lack of coordination with emergency responders.

The APS report concluded that four issues must be addressed in future BESS installations: barriers to limit cell-to-cell and module-to-module cascading; ventilation and cooling; a combined strategy of fire suppression followed by ventilation and cooling strategies; and response procedures that incorporate system monitoring, the detection of gases, ventilation practices, extinguishing methods, and critical information.

[Japan] JERA, ADEME Investment SAS, and IDEOL Agreed to Jointly Invest in the Development of Commercial Scale Floating Offshore Wind Projects

JERA (a joint venture between Tokyo Electric Power Fuel & Power (headquarters: Tokyo)  and Chubu Electric Power (Headquarters: Nagoya City, Aichi Prefecture)), 100% French state-owned infrastructure investment company ADEME Investment SAS (Headquarters: Angers City, France)[1], and the leading French floating offshore wind technology company IDEOL (Headquarters: La Ciotat, France) announced on June 22, 2020, that they have agreed to establish an investment vehicle that will finance the development and construction phase of several commercial-scale floating offshore wind projects around the world. This includes two upcoming wind farms in Scotland and France, which will use IDEOL’s patented Damping Pool technology. The three parties are in discussion to determine the details of the partnership, including the investment amount.

Offshore wind power generation technologies can generally be divided into  two types: fixed structures connected to the offshore foundations called “bottom-mounted foundations” and “floating-type” structures where the foundation is floating on the sea.[2] Floating-type offshore wind turbines, which can be installed even in deep water, have significant potential to help expand the use of renewable energy in the future. The three companies are therefore trying to better understand floating-type offshore wind power and accelerate its global development through this partnership.[3] [4]

[Japan] Hokuriku Electric Power and JFE Engineering Seeks to Expand the Use of AI-based WinmuSe System to Optimize Dam Operation

On June 12, 2020, Hokuriku Electric Power (Rikuden, Headquarters: Toyama City, Toyama Prefecture) and JFE Engineering, an engineering company headquartered in Tokyo, announced that they had jointly developed an optimal operating system for dams using AI (Artificial Intelligence) technology, which will help increase hydroelectricity power plants’ generation. The system mainly utilizes the WinmuSe, an AI-based water inflow forecasting application developed by JFE Engineering.

The two companies have jointly demonstrated WinmuSe at Rikuden’s Asaida Dam, located in Takayama City, Gifu Prefecture, since FY 2017. Its forecasting function was successfully improved through advanced analysis of large amounts of data related to Asaida Dam’s amount of rainfall and water inflow in past years. The results of the demonstration project showed excellent performance, with a high level of accuracy in forecasting water inflow. The project also confirmed that the system could be expected to increase the generation of hydroelectricity power plants by approximately 5 GWh per year.

Based on the results, Rikuden and JFE Engineering plan to apply the AI-based optimal operating system to other dams in the entire Jinzu River Water System, aiming to maximize their power generation.[1]

[USA] Duke and Dominion cancel Atlantic Coast Pipeline amid ongoing legal battles

On July 5, 2020, Duke Energy and Dominion Energy announced that they are cancelling the Atlantic Coast Pipeline—originally slated to run 600 miles from West Virginia to eastern North Carolina to provide additional natural gas capacity in the region—due to ongoing delays and cost uncertainty.[1][2] The Atlantic Coast Pipeline project has run into several legal challenges which has increased cost estimates from $4.5 billion to $8 billion. In June 2020, the Supreme Court ruled 7-2 overturning a lower court’s decision to block the pipeline from crossing beneath the Appalachian Trail, a protected national scenic trail overseen by the U.S. Forest Service. Despite this win, Duke and Dominion pointed to other legal battles as barriers to the project. In particular, the U.S. District Court for the District of Montana decision to overturn federal permit authority for waterbody and wetland crossings and a Ninth Circuit ruling on May 28, 2020 are stated as major concerns.

In addition to the announcement regarding the Atlantic Coast Pipeline, Dominion announced the sale of its natural gas transmission and storage assets to a Berkshire Hathaway affiliate for $9.7 billion.[3] However, this sale does not include Dominion's interest in the Atlantic Coast Pipeline.

[USA] Vectren Energy announces plans to reduce coal mix 78% to 12% by 2025

On June 15, 2020, Vectren Energy, a subsidiary of CenterPoint Energy based in Indiana and parts of Ohio, announced it would retire 730 MW of coal by 2030 which would bring its resource mix to 12% coal-fired power by 2025.[1] As of 2020, the utility’s generation portfolio is 78% coal. Under Vectren’s preferred integrated resource plan (IRP), which is based on an all-resource request for proposals, the utility would add 700 MW to 1000 MW of solar+storage, 300 MW of wind, 30 MW of demand response resources and 460 MW of combustion turbine natural gas plants. In total, the mix would be 64% renewable energy plus demand response by 2025. According to Vectren, the proposed plan is expected to reduce greenhouse gas emissions (GHG) 75% below 2005 levels by 2035 and save customers up to $320 million over the next 20 years.

In recent years, the utility has been under pressure from state legislators to keep Indiana coal online. In 2019, Indiana lawmakers proposed legislation that would place a moratorium on new resources in the state in order to protect coal-fired power from getting replaced.[2] Though the bill failed in the 2019 legislative session, in early 2020 lawmakers passed House Bill 1414 which makes coal plants in the state more difficult to retire.[3] Vectren’s new plan, though, bucks these pressures.

[USA] Minnesota Power energizes Great Northern Transmission Line

On June 11, 2020, Minnesota Power, the state’s second largest investor-owned utility, energized its 224-mile, 500 kV transmission line, Great Northern Transmission Line (GNTL), that will bring the utility to 50% renewable energy in 2021.[1] The GNTL brings 250 MW of hydropower from Manitoba, Canada to Northern Minnesota and was completed in February 2020. With the GNTL energized and connected to Manitoba Hydro’s Manitoba Minnesota Transmission Project, the utilities now have a unique “mechanism that quickly balances energy supply and demand in Minnesota and Manitoba" which enables the utilities to use wind power more effectively. The utility first filed permits for the project in 2014. This is a big shift for Minnesota Power which generated most of its power from coal in the early 2000s.[2] Now, the only coal units in the utility’s portfolio are Boswell Energy Center’s 355 MW and 585 MW units 3 and 4, respectively.

[USA] Alabama regulators approve Southern Company’s request for nearly 2 GW of natural gas

On June 9, 2020, the Alabama Public Service Commission (PSC) unanimously voted to authorize Southern Company to buy, build, or contract for nearly 2 GW of natural gas resources to guarantee system resilience.[1] Previously, Alabama Power, a Southern Company subsidiary, had announced that it is switching from a summer-peaking to a winter-peaking system, and proposed several expansions in solar, energy efficiency, and natural gas for a total of about $1.1 billion. According to Alabama Power, the additions are part of a nearly 20% fleet capacity increase necessary for resilience. In addition to the approval of natural gas, about 200 MW of energy efficiency programs were approved. However, regulators did not approve the five proposed solar-plus-storage projects, stating that those resource additions should be considered on a separate docket not focused on resiliency.

The decision not to include solar-plus-storage has received backlash from environmental groups who claim that the solar-plus-storage projects would have saved customers more. According to Docket participants from Energy Alabama and the Southern Environmental Law Center, an environmental advocacy group and an environmental public interest law firm, respectively, Alabama Power’s analysis showed solar-plus-storage options were the least costly solution.[2]

[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]
