Japan – TANAKA to Install 500 kW Fuel Cell System to Promote the Use of Hydrogen Energy at Production Plants
TANAKA to Install 500 kW Fuel Cell System to Promote the Use of Hydrogen Energy at Production Plants
Seeking to cut CO2 emissions at least 50% by 2030 using 500 kW stationary pure hydrogen fuel cell system, which boasts among the largest generating capacities in Japan*1
TOKYO, Mar 27, 2024 – (JCN Newswire) – TANAKA Holdings Co., Ltd. (Head office: Chiyoda-ku, Tokyo; Group CEO: Koichiro Tanaka) announces that TANAKA Precious Metals will install a stationary pure hydrogen fuel cell system with a maximum generating capacity of 500 kilowatts (kW), one of the largest in private-sector use in Japan, at the Shonan Plant in Kanagawa Prefecture, a key recycling business site for TANAKA. It has decided to install an H2Rex™ pure hydrogen fuel cell system manufactured by Toshiba Energy Systems & Solutions Corporation to optimally control generating efficiency. Operation is scheduled to commence in 2026.
Initiatives for Achieving Carbon Neutrality
TANAKA is currently carrying out Operation Polaris*2 with the objective of achieving carbon neutrality by 2050. To achieve at least a 50% reduction of CO2 emissions by 2030 (compared to 2013 levels), proactive steps are being taken, including enhancing energy efficiency, optimizing manufacturing processes, implementing green energy solutions, and pursuing additional measures aimed at emission reduction. The recent decision to use hydrogen energy is a part of these efforts.
Pure Hydrogen Fuel Cell Systems
The pure hydrogen fuel cell system to be introduced generates electricity by making use of a chemical reaction that combines hydrogen and oxygen, the reverse of the electrolysis of water. Since the system directly uses hydrogen to generate electricity, unlike household fuel cell systems that extract hydrogen from city gas and other sources, it is able to generate electricity with high efficiency and zero CO2 emissions. Additionally, in the event of a disaster, the system can be used to supply backup electric power without interruption. Such systems also give consideration to the local environment, due to their low noise and vibration.
Effects of Introduction
With the introduction of this system, 25% of the electricity used at the Shonan Plant will be switched to power generated by the fuel cell system, with an expected reduction in CO2 emissions of 1,979 tons annually (this and subsequent figures are estimates by TANAKA). This is equivalent to 32% of the plant’s CO2 emissions reduction target for 2030.
Participation in Councils for Achieving Carbon Neutrality
TANAKA will continue to expand its use of hydrogen energy even after the introduction of the system. In conjunction with this, hydrogen demand will increase, and TANAKA has high hopes for Kawasaki City*3, an advanced hydrogen city in Kanagawa Prefecture, and seeks to build a hydrogen supply base in the waterfront area. TANAKA joined the Kawasaki Carbon Neutral Industrial Complex Formation Promotion Council and the Kawasaki Carbon Neutral Port Formation Promotion Council, two public-private collaborative bodies made up of companies and other organizations in agreement with the city’s vision and strategies that were established to investigate and promote measures for achieving carbon neutrality. By joining the councils, TANAKA hopes to deepen collaboration with the city and other member companies.

Japan – TANAKA Holdings to Relocate Head Office to New Building in Kayabacho, Site of Group’s Founding
TANAKA Holdings Co., Ltd. (Head office: Chiyoda-ku, Tokyo; Group CEO: Koichiro Tanaka), the sole holding company of TANAKA Precious Metals, announced today that it constructed a new head office building in Nihonbashi Kayabacho, Chuo-ku, the founding site of TANAKA Precious Metals, and will relocate head office functions to the new building on April 1, 2024.
Relationship Between Kayabacho and TANAKA Precious Metals
Founder Umekichi Tanaka trained at a pawn brokerage in Tokyo called Ejimaya and opened Ejimaya Tanaka Shoten, a money exchange firm, in 1885. Later, the company transitioned from money exchange to the bullion trading business and started melting down and refining purchased foreign currency to sell the metal. The techniques acquired during this period led to the development and manufacture of precious metal products and materials used in industrial areas. Subsequently, TANAKA Precious Metals has consistently delivered a diverse range of technologies and services tailored to meet evolving demands while exploring the expansive potential of precious metals.
The founding site, located in Kitajima-cho, Nihonbashi-ku, Tokyo (currently Nihonbashi Kayabacho, Chuo-ku), was the location of TANAKA Kikinzoku Kogyo K.K.’s head office from 1885 to 2006, but the head office functions were relocated to Tokyo’s Marunouchi district in 2006. To remain at the cutting edge as a leading precious metals company and to develop even further while maintaining the founding philosophy, TANAKA Holdings decided to return head office functions to Kayabacho, the Group’s founding site in a community that continues to undergo remarkable evolution, including redevelopment of surrounding areas and establishment of sites that promote interaction among generations.
Concept Incorporated into the New Head Office Building
The new head office building was designed based on the concept of “Connecting with people, the city and the future” and the idea of serving as a site for creating a more promising future while interacting with various people and achieving harmony among diverse values.
The exterior of the new building adopts calm colors, and the limited space is used to create a site that incorporates greenery and effectively evokes a sense of nature to achieve harmony with the tranquil townscape of Kayabacho, which has developed throughout history.
The new building features an open staircase in the center to create a barrier-free atmosphere and promote openness and candid communication among employees. In addition, to encourage Activity Based Working (ABM), a work style that enables flexible selection of working place and time according to the specific details and circumstances of one’s work, the new building adopts a free-address system and has a layout with a variety of different spaces ranging from web-enabled booths that facilitate individual work to meeting spaces that can easily accommodate variable numbers of people.
The building also has DOCK2085, a future concept room that will serve as a site for innovation initiatives by TANAKA Precious Metals. Here, we will envision the global environment in 2085, including climate and resources, as well as the industries that support people’s lives, including food, healthcare, and cities. We will also tackle the challenges of finding solutions to global environmental and social issues and creating a sustainable future through research, development, and collaboration with world-class engineers.
Not only did we take measures to reduce environmental impact during construction, but the new building satisfies the Zero Energy Building (ZEB) Ready standards, based on an assessment that energy consumption will be 51% lower than that required by a conventional building through the adoption of high-efficiency equipment and the active use of natural energy to reduce energy consumption.

Japan – TANAKA Establishes New Method of Recovering Precious Metals Adhering to Vacuum Film Formation Equipment Components
TANAKA Establishes New Method of Recovering Precious Metals Adhering to Vacuum Film Formation Equipment Components
Developing supply systems by 2025, promoting the recycling of limited precious metal resources, and contributing further to the circular economy
TOKYO, Jan 31, 2024 – (JCN Newswire) - TANAKA Kikinzoku Kogyo K.K. (Head office: Chiyoda-ku, Tokyo; Group CEO: Koichiro Tanaka), which develops industrial precious metals products as one of the core companies of TANAKA Precious Metals, announced that it has established a jig cleaning method called TANAKA Green Shield. This cleaning method is characterized by nickel plating on the adhesion-preventing plate[1], a component of vacuum film formation equipment[2] used in semiconductor manufacturing and other processes. When using a nickel-plated adhesion-preventing plate, PGM[3] sputtered films, including platinum and palladium, can be easily detached from the plate.
TANAKA is developing a recycling business for this use case. After detaching sputtered films adhering to components, mainly made from stainless steel, of vacuum film formation equipment such as sputtering and vacuum deposition equipment, the recovered precious metals are refined and returned to the customer with the precision-cleaned components.
This cleaning method takes advantage of a unique TANAKA technology related to base plating. Applying a nickel plating to an adhesion-preventing plate enables PGM sputtered films to be detached through chemical treatment without damaging the base material. This method makes it easier than previous methods to detach PGM sputtered films, so it is expected to reduce the amount of cleaning agent required when cleaning equipment, in turn contributing to reduced environmental impact. With an anticipated reduction in recovery loss of precious metals scattered around during the grinding process, this method is also expected to achieve higher PGM recovery rates with lower costs.
TANAKA aims to develop the TANAKA Green Shield system to support a wide variety of component shapes and sizes and to expand PGM film recovery rates by six times the current level by 2025.
Jig Cleaning Method
There are multiple jig cleaning methods for vacuum film formation equipment components, including physical detachment (blast cleaning) and thermal sprayed aluminum base film formation. Physical detachment, in which an abrasive agent (cleaning agent) is sprayed to remove an adhered film, is currently a commonly used jig cleaning method due to its low cost. Use of an abrasive agent damages the surface of the base material, thereby leading to reduced lifetime of the base material. Another disadvantage of this method is that material is scattered during the process, causing a loss in precious metal recovery.
Another method for detaching an adhered film is the thermal sprayed aluminum base film formation method of jig cleaning. This requires the adhesion-preventing plate to be coated with aluminum in advance using a thermal spraying method, and the aluminum to be then dissolved with chemicals. Drawbacks of this approach include challenges in recovering adhered film from surfaces lacking an aluminum coating, as well as the elevated cost associated with forming the aluminum film.
TANAKA Green Shield is a base preparation method whereby nickel plating is applied to an adhesion-preventing plate prior to use. After using a plate in a sputtering process, for example, only the nickel plate coating between the adhesion-preventing plate and PGM sputtered film is dissolved. This enables not only the PGM sputtered film but also other adhered films with various compositions to be detached from the plate without damaging the base material. This base preparation has a high level of adhesion with adhesion-preventing plates and sputtered films, which can prevent sputtering defects caused by peeling of sputtered film. A wide variety of component shapes can also be nickel-plated with this method. In addition to preventing degradation of the base material, this cleaning method is cheaper than the aluminum film formation method. It also requires lower amounts of cleaning agent, making it an environmentally friendly, next-generation jig cleaning method.
TANAKA and the Circular Economy
Since it was founded in 1885, TANAKA has continuously operated a precious metals recycling business. In addition to its existing precious metals recycling technologies, developed through research into precious metals over these many years, the company is now developing the TANAKA Green Shield, with a range of new precious metals recycling technologies. TANAKA’s precious metals recycling business promotes the recycling of limited precious metal resources and contributes to the realization of a circular economy.
