TOKYO, June 12, 2026 - (JCN Newswire) - NEC Corporation (NEC; TSE: 6701) announced the release of the final report from the Net Carbon Impact project conducted by the European Green Digital Coalition (hereinafter "EGDC")(1), which quantitatively assessed the decarbonization effects of implementing NEC’s smart agriculture solution "CropScope"(2).

The final report is available here: https://www.greendigitalcoalition.eu/case-studies-deployment-phase/#agriculture

The EGDC is a coalition of companies established at the request of the European Council, with the support of the European Parliament and the European Commission, with the aim of reducing greenhouse gas emissions across society through the use of digital technologies.

Under this initiative, the net carbon impact of digital technologies is quantitatively assessed as a measure of emissions reduction by comparing scenarios in which digital technologies are "used" and "not used", based on a scientific methodology developed by the EGDC.

About Net Carbon Impact

Net carbon impact refers to the overall net reduction in greenhouse gas emissions achieved through the adoption of digital technologies, calculated by subtracting the additional emissions generated through the manufacturing, operation, and disposal of the equipment required to implement those technologies from the emissions reductions enabled by the technologies themselves.

Because it also takes into account increase in emissions associated with the use of such equipment, net carbon impact enables an objective assessment of the actual emissions reduction effect that the adoption of a given technology has across society as a whole.

Overview of the Case Study

This case study focused on the variable-rate fertilization function incorporated into NEC’s smart agriculture solution, "CropScope." Variable-rate fertilization is a method in which fertilizer is applied at optimized rates for each area of a field according to crop growth conditions and soil conditions, rather than applying the same amount uniformly across the entire field.

The study compared scenarios in which CropScope’s variable-rate fertilization function was implemented and not implemented at farms in Hokkaido, Japan, and comprehensively evaluated:

• the reduction effect on fertilizer usage achieved through variable-rate fertilization; and
• the net carbon impact resulting from reduced fertilizer usage.

As a result, CropScope’s variable-rate fertilization function was confirmed to have a tangible effect on reducing greenhouse gas emissions in the agricultural sector.

How Variable Rate Fertilization Contributes to Decarbonization

Fertilizers used in agriculture contain nitrogen, which is essential for crop growth. However, when fertilizer is applied in amounts exceeding what crops can absorb, excess nitrogen remains in the soil. This residual nitrogen is transformed through the activity of soil microorganisms, generating nitrous oxide (Nâ‚‚O), a greenhouse gas, in the process.

Nitrous oxide is a greenhouse gas with a global warming potential approximately 270 times greater than that of carbon dioxide. Accordingly, appropriately reducing fertilizer use through variable-rate fertilization helps suppress nitrous oxide emissions and can make a significant contribution to decarbonization across society.

Reduction Effects by Crop (Winter Wheat, Spring Wheat, Corn) (3)

In this report, we examined the effects over the entire growing season for three crop types: winter wheat, spring wheat, and corn. The main findings for each crop are as follows.

For all crops evaluated, the net carbon impact achieved through reduced fertilizer use significantly exceeded the average emissions generated by tractor operations during the cultivation period.

These results quantitatively demonstrate that implementing CropScope’s variable-rate fertilization function can reduce unnecessary fertilizer use while also contributing to lower environmental impact.

Secondary Effects Beyond Greenhouse Gas Reductions

In addition to greenhouse gas reductions, this assessment also identified the following secondary benefits:

• Economic benefits for farmers through reduced fertilizer costs
• Improved water quality and reduced risks of eutrophication and adverse ecological impacts through the suppression of fertilizer runoff
• Improved soil health, such as enhanced soil organic matter retention

These findings indicate that variable-rate fertilization technology utilizing digital technologies can contribute both to agricultural sustainability and to climate change mitigation.

Looking Ahead

NEC will leverage the insights gained from this initiative to promote decarbonization in the agricultural sector and work toward the creation of agriculture-based carbon credits.

NEC will continue to contribute to the simultaneous advancement of both DX (Digital Transformation) and GX (Green Transformation) across society through the use of digital technologies.

HIROSHIMA, Japan, June 8, 2026 - (JCN Newswire) - Mazda Motor Corporation (Mazda) conducted a demonstration test of its under development onboard COâ‚‚ (carbon dioxide) capture system, ‘Mazda Mobile Carbon Capture,’ during Round 3* of the Super Taikyu Series 2026, held from June 5 to 7, 2026. During the test, Mazda successfully demonstrated COâ‚‚ storage during driving, newly added to this round of testing, marking a step forward toward the practical application of the system and the achievement of carbon negativity.Under the theme “The Joy of Driving Fuels a Sustainable Tomorrow,” Mazda announced “Mazda Mobile Carbon Capture” at last year’s JAPAN MOBILITY SHOW 2025, and is aiming to realize mobility that reduces COâ‚‚ the more you drive by 2035.

In this demonstration test, a COâ‚‚ desorption function of the adsorption unit and a COâ‚‚ storage tank were added to the race car “MAZDA SPIRIT RACING 3 Future concept” (No. 55), which was driven using carbon-neutral fuel—hydrotreated vegetable oil (HVO) which is already in practical use in Europe. As in the previous test, zeolite with a porous structure was employed as the adsorbent. Zeolite readily releases COâ‚‚ when heated, enabling the captured COâ‚‚ to be desorbed using the exhaust heat generated during driving. The desorbed COâ‚‚ is then compressed by an electric compressor and stored in a tank. Mazda has successfully demonstrated this integrated process as a complete system for the first time. As a result of repeating this process throughout the 24-hour race, a total of 804 grams of COâ‚‚ was captured, achieving a significant advancement—approximately 9.6 times the previous result of 84 grams.

In addition to the storage experiment, the combined effect of COâ‚‚ reduction achieved through HVO and the amount of COâ‚‚ captured by the system temporarily exceeded the target recovery level assumed for typical use of Mazda production vehicles, confirming the potential for carbon-negative operation in production vehicles, albeit for a limited period. Building on these results, Mazda is embarking on a new phase of challenges aimed at achieving carbon negativity in racing cars, which operate under higher loads and more demanding conditions. Specifically, Mazda aims to achieve short-term carbon negativity in its racing car at Round 7 of the Super Taikyu Series, to be held this November.

Moving forward, Mazda will continue to collaborate with numerous partners to further refine the technology and equipment based on the insights gained to date, contributing to the realization of a sustainable mobility society.

TOKYO, June 8, 2026 - (JCN Newswire) - National Maritime Research Institute (NMRI), National Institute of Maritime, Port and Aviation Technology and Mitsubishi Shipbuilding Co., Ltd., a part of the Mitsubishi Heavy Industries (MHI) Group, have begun integrating the "OCTARVIA" programs developed by NMRI to evaluate and analyze ship performance in actual seas with the "MiPoLin®" power prediction and lines selection system developed by Mitsubishi Shipbuilding.

The OCTARVIA programs (the ship lifecycle fuel efficiency evaluation program "OCTARVIA-web V2.1" and the actual ship monitoring data analysis program "SALVIA-OCT.-web V2.2"), which are released on NMRI cloud on June 5, 2026, allow users to import hull geometry and performance data generated by MiPoLin® into the OCTARVIA programs, enabling seamless execution of ship lifecycle fuel consumption estimates and ship performance evaluations based on ship monitoring data.

Through this collaboration, NMRI and Mitsubishi Shipbuilding will promote dissemination of OCTARVIA programs and MiPoLin® and thereby support efforts to reduce greenhouse gas emissions in the maritime sector.

NMRI is currently working to enhance the functionality of the following programs developed under the Japan Maritime Cluster Collaborative Research Project on Evaluation of Ship Performance in Actual Seas (OCTARVIA) with the aim of social implementation:

Program for estimating ship lifecycle fuel consumption (OCTARVIA-web)Program for onboard monitoring data analysis (SALVIA-OCT.-web)Program for providing ship form and ship performance data from the principal dimensions (EAGLE-OCT.-web)-an input support tool for OCTARVIA-web and SALVIA-OCT.-web-

Mitsubishi Shipbuilding has developed "MiPoLin®" , a user-friendly, highly accurate power prediction and lines selection system that leverages over 1,200 tank test results accumulated over more than 100 years at the Mitsubishi Nagasaki Experimental Tank, as well as data from more than 420 ship designs. The company provides this system to enable Mitsubishi Heavy Industries Group's technologies to be widely utilized in solving problems across the entire maritime industry.

To enhance the input support for OCTARVIA-web and SALVIA-OCT.-web, NMRI added an integration functionality with the MiPoLin® to the previous version of the programs. On June 5, 2026, NMRI is releasing OCTARVIA-web V2.1 and SALVIA-OCT.-web V2.2 on the NMRI cloud.

This functionality enables users not only to estimate hull geometry and performance based on ship principal particulars, as was previously possible, but also to seamlessly integrate ship databases and tank test databases into the OCTARVIA programs. This allows shipping companies and other organizations to perform more accurate estimates of ship lifecycle fuel consumption and analyze onboard monitoring data.

Through these programs, NMRI and Mitsubishi Shipbuilding will promote the reduction of GHG emissions from the maritime sector.

TOKYO, June 8, 2026 - (JCN Newswire) - The Nippon Foundation, in partnership with the Ministry of Foreign Affairs of Japan and the Intergovernmental Oceanographic Commission (IOC) of UNESCO, convened the inaugural Island States Ocean Summit in Tokyo on 3–4 June 2026.

At the Closing Session on 4 June, Yohei Sasakawa, Honorary Chair of The Nippon Foundation, announced the Summit’s principal outcome: the launch of the OCEAN STATES INITIATIVE, a new long-term framework designed to support island states in addressing the growing challenges facing the ocean while advancing sustainable development.

The Initiative builds on more than three decades of The Nippon Foundation’s support for island nations and responds to what Summit participants described as a growing “polycrisis”—a combination of climate change, sea-level rise, biodiversity loss, marine pollution, increasingly severe natural disasters, and a shortage of scientific and policy expertise.

The OCEAN STATES INITIATIVE seeks to strengthen the capacity of island states to protect and sustainably use their ocean resources while building resilient and sustainable ocean economies. The Initiative reflects the Summit’s emphasis on moving beyond discussion and toward practical implementation, supported by science, partnerships, and long-term investment.

Built on a new framework for international cooperation among island states, governments, international organizations, and philanthropic partners, the Initiative aims to support island states on the front lines of climate and ocean challenges while contributing to global efforts to achieve a sustainable ocean future.

Announcing the Initiative, Mr. Sasakawa stated:

“Through the discussions at this Summit, we have gained a clearer understanding of the actions island states seek from the international community. The Nippon Foundation will invest in people, create platforms for collaboration, and advance concrete initiatives that generate innovation and impact. Together with all those gathered here—across countries, sectors, and generations—we will translate this vision into action and ensure that the benefits of our ocean are passed on to future generations.”

In response, H.E. Surangel S. Whipps Jr., President of the Republic of Palau and Summit Co-Chair, stated:

“We leave Tokyo with something tangible, and practical. We believe the platform being shaped at this summit is the exact mechanism needed to help all Island States translate our plans into real action.”

Vidar Helgesen, Executive Secretary of the Intergovernmental Oceanographic Commission (IOC) of UNESCO and Summit Co-Chair, stated: “Island states are not starting from zero. The foundations for Sustainable Ocean Planning and Management already exist in many countries through national ocean policies, marine spatial planning and sustainable blue economy initiatives. Our task now is to connect, strengthen and scale these efforts, creating a coherent framework that maximises impact and reduces fragmentation.”

The Summit brought together approximately 300 participants, including His Majesty the Emperor of Japan, Prime Minister Sanae Takaichi, His Royal Highness Crown Prince Haakon of Norway, Heads of State, ministers and senior officials from 35 countries, representatives of United Nations agencies, research institutions, civil society organizations, and ocean experts.

Participants discussed Sustainable Ocean Planning and Management approaches as a means to address climate-related ocean risks, marine resource management, biodiversity conservation, and pathways for balancing ocean conservation with sustainable economic development. The discussions culminated in the release of the Co-Chairs’ Summary on 4 June.

The OCEAN STATES INITIATIVE

The OCEAN STATES INITIATIVE is The Nippon Foundation’s new action plan to support island states through human resource development, scientific knowledge, and international cooperation, with the goal of balancing ocean conservation and sustainable economic development with a vision to the centuries and millennia to come.

The Initiative is built around three pillars.

Pillar 1: Strengthening Support for Island States through Human Resource Development

The Initiative will develop professionals from island nations who can address today’s challenges while preparing the next generation of leaders to shape the future. It will also cultivate global talent capable of advancing innovative ocean policies that reflect the voices of island states and support practical solutions. The Nippon Foundation’s human capacity development programs have already trained 2,032 fellows from 158 countries, creating a global network that supports ocean governance and policy implementation.

Pillar 2: Establishing OCEAN HUB

As a legacy of the Summit, The Nippon Foundation will establish OCEAN HUB, a Tokyo-based hub that will serve as both a focal point for the global network of experts and a coordinating center for existing and future initiatives. The Initiative will also promote innovative projects through a consortium of world-leading institutions, generating the latest science and evidence needed to support ocean policy and decision-making. Together, these efforts will create a hub linking experts, science, and policy.

Pillar 3: Developing Innovative Projects with States and the United Nations for SOPM

The Nippon Foundation and the IOC of UNESCO will jointly develop a Sustainable Ocean Planning and Management Support Platform to assist island states in implementing Sustainable Ocean Planning and Management (SOPM). To support implementation, The Nippon Foundation will provide seed funding and work with the IOC to establish a dedicated fund that encourages contributions from Member States and partners, helping expand and sustain the Platform over time. The long-term objective is to transform partnerships into projects that drive innovation and deliver measurable impact.

Looking Ahead

The OCEAN STATES INITIATIVE is designed as a ten-year strategy. As a key milestone, The Nippon Foundation intends to convene the Second Island States Ocean Summit in 2030–2031, which will serve as the mid-term review of the Initiative and help shape its second phase.

Summit Outcomes and International Processes

The Summit’s Co-Chairs’ Summary notes that the partnerships, commitments, and knowledge generated through the Summit will contribute to major international policy processes, including:

• COP17 of the Convention on Biological Diversity
• COP31 of the United Nations Framework Convention on Climate Change (UNFCCC)
• The BBNJ process

TOKYO, June 4, 2026 - (JCN Newswire) - INPEX CORPORATION (INPEX), Osaka Gas Co., Ltd. (Osaka Gas), and Mitsubishi Heavy Industries, Ltd. (MHI) today started operations of a system to facilitate the transfer and management of Clean Gas Certificates, part of a demonstration project being jointly conducted by INPEX and Osaka Gas aimed at developing practical technology for the reduction and effective utilization of CO2 emissions by using one of the world's largest-class methanation systems (hereinafter, the "Nagaoka Methanation Demonstration").(1) This system, which is being developed by Osaka Gas and MHI using the CO2NNEX®(2) digital platform, is the first of its kind in the city gas industry for transfer and management of Clean Gas Certificates to certify the environmental value(3) of e-methane.

The Nagaoka Methanation Demonstration is a project to produce e-methane from hydrogen (H2) and carbon dioxide (CO2) recovered from the Koshijihara Plant at the INPEX JAPAN Nagaoka Field Office (Nagaoka City, Niigata Prefecture), for planned delivery to customers through INPEX JAPAN's natural gas pipeline. The e-methane produced at the clean gas production facility, which was certified in January 2026, received clean gas equivalent amount certification on May 29.(4)

Going forward, to build a model for local production and local consumption envisioned as part of the Nagaoka Methanation Demonstration, the partners will convert the environmental value of e-methane into Clean Gas Certificates, and together with Nagaoka City, as well as commercial firms Asahi-Shuzo Sake Brewing Co., Ltd. and Iwatsuka Confectionery Co., Ltd., which are located near the demonstration test facility, will work to transfer and manage clean gas certificates using CO2NNEX. (Fig.1)

Fig. 1: Envisioned Initiatives using CO2NNEX

In addition to providing data, such as the amount of e-methane, the raw material used in its production (CO2 and H2), and the volume of CO2 emissions across the lifecycle, CO2NNEX enables visualization and central management for the acquisition and use of Clean Gas Certificates, allowing for more advanced progress management for the entire demonstration project. (Fig. 2, integrating and managing the input data on the left and the output data on the right using CO2NNEX)

Fig. 2: Progress management for the entire demonstration project (System screen image)

Going forward, Japan's Ministry of Economy, Trade and Industry (METI) plans to conduct a system demonstration project for Environmental Value Certificates for next-generation fuels, including liquid fuels (e-gasoline, SAF) and gaseous fuels (e-methane, biogas).(5) Operations of CO2NNEX in the Nagaoka Methanation Demonstration aim to provide a precedent for the establishment of the certificate system in the future, in the expectation that the experience gained and knowledge obtained will be useful in the consideration of the certificate system.

Through this initiative, INPEX, Osaka Gas, and MHI will contribute to the practical application of e-methane and the realization of a carbon-neutral society.

(1) Nagaoka Methanation Demonstration: Project entitled "Development of CO2 utilization technology for gaseous fuel and Development of practical technology for pipeline injection using large-scale CO2-methanation system", subsidized by Japan's New Energy and Industrial Technology Development Organization (NEDO). Injection of produced e-methane into natural gas pipelines began on February 20, 2026. The test facility was certified as a clean gas production facility under the Clean Gas Certificate System on January 27, 2026.
For details, see the following press release:

(3) Environmental value: Since CO2 emitted into the atmosphere (or CO2 in the atmosphere) is captured and carbon recycled as raw material for e-methane, even when e-methane is used (burned), the amount of CO2 in the atmosphere does not increase in real terms, so CO2 emissions are effectively zero.

(4) Clean gas production facilities, clean gas equivalent: Under the clean gas certificate system, managed in part by the Japan Gas Association (JGA), e-methane and biogas, which carry environmental value (considered not to increase atmospheric CO2 even when burned), are certified as clean gas and issued Clean Gas Certificates through a process that involves certification of the clean gas production facility, and certification of the equivalent amount of clean gas produced at the certified facility. For details, see the Clean Gas Certificate Evaluation Committee website (Japanese): https://www.clean-gas-certificate.com/

TOKYO, June 4, 2026 - (JCN Newswire) - The Nippon Foundation, in partnership with the Ministry of Foreign Affairs of Japan and the Intergovernmental Oceanographic Commission (IOC) of UNESCO, officially opened the Island States Ocean Summit on June 3, 2026 at Hotel New Otani Tokyo. His Majesty the Emperor attended the Opening Ceremony and delivered remarks. Prime Minister Sanae Takaichi also attended the Opening Ceremony and delivered an address, underscoring the Government of Japan’s strong support for the Summit and its outcomes. Approximately 300 participants, including heads of state, ministers, senior officials, and experts from 35 countries across the Pacific, Caribbean, and Indian Ocean regions, are taking part in the Summit.

Building on discussions held throughout the two-day Summit, The Nippon Foundation will announce a new action plan to strengthen support for island states on the evening of June 4.

Remarks by His Majesty the Emperor

At the Opening Ceremony, His Majesty the Emperor delivered remarks. The full text of His Majesty’s remarks is attached as Annex 1.

Opening Ceremony Highlights

Representing the host organization, Yohei Sasakawa, Honorary Chair of The Nippon Foundation, delivered the opening address.

Mr. Sasakawa stated:

“Today, island states face serious threats, including sea-level rise and extreme weather events caused by climate change. These challenges can no longer be solved by any one country or institution alone. Through this Summit, we must bring together our wisdom and determination to inspire global solidarity and action.”

He reaffirmed the Foundation’s commitment to further strengthening its support for island states through the outcomes of the Summit.

His Royal Highness Crown Prince Haakon of Norway emphasized the importance of Sustainable Ocean Planning and Management, stating:

“At the same time, the ocean is not only a victim of climate change. It is a solution, continuing to offer opportunities that can bring benefits to nature and people in island states. Sustainable ocean planning and management can create frameworks for attracting investment in green ocean industries.”

He highlighted the importance of strengthening climate resilience in island states while advancing sustainable ocean economies through science-based ocean management.

Speaking on behalf of island states and serving as Summit Co-Chair, H.E. Surangel S. Whipps Jr., President of the Republic of Palau and Chair of the Alliance of Small Island States (AOSIS), stated:

“The ocean is not a backdrop to our lives. It is our economy. Our food security. Our culture. Our very sovereignty. And it is changing faster than our communities can adapt. As AOSIS Chair, I speak for nations that together contribute less than one percent of global emissions, yet we face the most severe impacts of global warming. International climate and ocean governance is not delivering for the most vulnerable. We need action that matches the urgency.”

Prime Minister Takaichi,
Your Excellencies,  
Dr. Yohei Sasakawa,  
Distinguished Guests and Participants,

It gives me great pleasure to be here today to attend the opening of the Island States Ocean Summit together with all of you.  

Japan, as an island nation, has from ancient times reaped the rich blessings of the ocean. As we witness rising sea levels due to global warming and a series of disasters caused by extreme weather around the world, I am deeply reminded of the importance of maintaining the delicate balance on Earth through the grand water cycle, where water is brought in from the sea and returns to the sea.

I myself have for many years been interested in water issues, including safe drinking water, sanitation, water transport, climate change and water-related natural disasters, which are deeply intertwined with national and global challenges. I have always hoped that discussions on these issues would be deepened further around the world.

It is my understanding that the purpose of this summit is to promote, through collaboration between private organizations, governments, and international organizations, national-level plans in island nations that aim to achieve both marine environment conservation and sustainable use of marine resources.  

I would like to express my sincere respect to all of you gathered here and to the participating nations, as you cooperate in sharing your collective wisdom and experience, and, by building upon the latest science while at the same time preserving traditions, endeavor to address global issues through international cooperation.

To be mindful of the ocean and to work for its sound future is, in essence, nothing less than to safeguard our own future. As we face in our times many challenges, including rising sea levels, it is my earnest hope that a sense of solidarity among us will bring harmony and hope to the world.  

I extend my heartfelt gratitude to you all.

TOKYO, June 3, 2026 - (JCN Newswire) - Mitsubishi Heavy Industries, Ltd. (MHI), to contribute to the realization of a resource-circulating society, is working to develop and commercialize AdBio® (Biomass High-Efficiency Recovery and Recycling System),(1) a system to efficiently sort and recover biomass such as food waste and paper from municipal waste and unsorted food waste, enabling stable recovery of biogas in methane fermentation systems. MHI has recently received a technology verification report from the Japan Environmental Sanitation Center (JESC)(2) verifying that AdBio® is at a level for practical application in terms of technology, conducted as part of JESC's Waste Treatment Technology Verification Project.(3)

Recovered biogas is widely used as a source of green energy for electricity generation, heating, and fuel, so efficient recovery and recycling are required to realize a resource-circulating society. With the JESC report, AdBio® has now been recognized as a technology that enhances the efficiency of biomass sorting and recovery and improves degradation rates in methane fermentation, increasing biogas production and enabling stable operations.

When used for municipal waste, the introduction of AdBio® is expected to increase biomass recovery compared to conventional crushing and sorting methods. In addition, the improved degradability of paper and other waste material is projected to provide an approximately 40% increase in biogas generation. Further, the system will allow a wide range of raw materials, such as agricultural waste, to be utilized for methane fermentation, leading to further growth in biogas production and use.

This system can be installed at existing methane fermentation facilities as well as newly built plants, supporting efficient green energy generation while ensuring steady raw material supply and operational stability. The system can also respond flexibly to changes in societal conditions that result in changes in processing volumes and the properties of the raw material, as well as diversifying raw material needs.

TOKYO, May 13, 2026 - (JCN Newswire) - Akasaka Heating & Cooling Supply Co., Ltd ("Akanetsu", a TBS Group company) held a Group "Hydrogen Heat Source Facility Commissioning Ceremony" on Tuesday, May 12, 2026.

The company supplies heating, cooling, and electricity to various buildings in the Akasaka 5-chome district of Minato-ku, Tokyo. In renewing its heat source facilities, the company has introduced hydrogen utilization equipment designed with safety in mind, while considering the potential of green hydrogen as a next-generation energy source. Full-scale operations commenced in May 2026. This facility marks the first instance in Tokyo where a private heat supply operator, for commercial purposes, accepts and stores green hydrogen, utilizing it for power generation via fuel cells and for heat supply via hydrogen-co-fired boilers.

First, Ryujiro Abe, President & Chief Executive Officer of TBS Holdings, stated: "The full-scale operation of this green hydrogen facility represents a major step towards the decarbonization of urban infrastructure, and demonstrates the potential of a new social infrastructure from Akasaka. Moving forward, we will continue to accumulate knowledge while ensuring safety and a stable supply, and we will continue to communicate our efforts to society through our GX initiatives. I would like to express my sincere gratitude once again for everyone's support."

Following this, Yuriko Koike, Governor of Tokyo, stated: “Hydrogen is one way to address both stable energy supply and decarbonization. Precisely because the supply of fossil fuels is unstable today, hydrogen is attracting more attention than ever as a game changer that can turn a challenge into an opportunity. The Tokyo Metropolitan Government is advancing a range of initiatives toward realizing a hydrogen society under three key concepts: ‘produce,’ ‘transport’ and ‘use.’ This hydrogen heat source facility is the first initiative to make full-scale use of green hydrogen in the very heart of Tokyo, and the Tokyo Metropolitan Government has supported its introduction. The facility is also expected to use green hydrogen procured through market-based trial transactions conducted by the Tokyo Metropolitan Government. I believe this is an extremely important initiative for expanding demand for green hydrogen in Tokyo. Taking today as a starting point, let us work together to further accelerate our progress toward realizing a clean and safe hydrogen society.”

During the ceremony, guests were shown the ‘hydrogen storage alloy’ contained within the plant's hydrogen tanks, enabling the safe storage of hydrogen at low pressure.

Subsequently, a live broadcast link was established with the hydrogen plant in Akasaka 5-chome, where the safety-focused hydrogen utilization facilities generate electricity and steam (thermal energy) from green hydrogen. The pure hydrogen fuel cells generate electricity directly from hydrogen and emit no CO₂ during power generation. The electricity generated is used for lighting and power systems within the plant facility, and in the event of an emergency, they can operate autonomously to secure power for essential power needs within the plant.

The hydrogen released from the hydrogen tanks then passes through piping within the facility to hydrogen-co-fired once-through boilers, where it is used in combination with city gas to produce steam (thermal energy). At the maximum hydrogen cofiring ratio of 50% by volume, each boiler is expected to reduce CO₂ emissions by approximately 21% compared with operation using city gas alone. The reduction effect may vary depending on operating conditions. (*The reduction effect varies depending on operating conditions.) The green hydrogen used in the facility is transported regularly from Yamanashi Prefecture. The introduction of the facility has received a grant from the Tokyo Metropolitan Government.

Morimasa Takagi, Representative Director and President of Akanetsu, reflected on the start of full-scale operations, stating: "I am deeply moved to have reached this milestone. This initiative began several years ago, and we have faced many challenges along the way." He went on to share his passion for further hydrogen utilization in the years ahead. "This year, Akanetsu joined the Council for Study of Hydrogen Supply Systems and Pipelines in Tokyo. It’s a great dream and source of daily inspiration that we’ll see hydrogen pipelines running through the streets of Akasaka, with TBS's GX efforts evolving even further."
