ENTSO E’s Offshore Network Development Plans 2024 report*1 highlights that by 2040, Europe is moving into a massive scale-up phase of offshore renewables, which requires major transmission expansion and early hybrid grids. Grids developed with MTDC systems can boost transmission capacity up to nearly threefold in a 2040 scenario.
*1 Offshore Network Development Plans European offshore network transmission infrastructure needs

Achieving the same capacity and reliability without these solutions would require substantial capital investment. Optimized assets not only translate into fewer converter stations, but also into fewer power cables and lines and a reduced use of land and materials, underpinning a more sustainable energy system for the benefit of both society and the environment.

Marking a significant step toward greater interoperability, the launch of AxoniQ comes as governments and grid operators worldwide accelerate investments in transmission infrastructure toward a fully electrified world to integrate renewable energy at scale, strengthen cross-border interconnections, and improve energy security.

The AxoniQ portfolio combines advanced power electronics and control technologies. It includes:

• AxoniQ Protect: An innovative solution that can interrupt a DC fault in less than three milliseconds, it offers fast and effective protection at up to 525 kilovolts (kV). It enables selective fault isolation by disconnecting only the affected section of the DC grid, while the rest of the system continues operating. This continuous, proactive protection enables extremely low losses and the optimal combination of performance, efficiency, and reliability throughout the entire lifecycle.
• AxoniQ Connect: A modular DC switching station that enables the connection of new terminals and structures the grid into several protection zones, creating manageable subsystems. AxoniQ Connect ensures reliable service continuity, simplifies maintenance, and supports cost-efficient scalability.
• AxoniQ Control: An advanced control system built with interoperability in mind that maintains voltage stability and power balance, optimized power flow, and flexible, market-driven energy exchange. AxoniQ Control addresses congestion and enables quick reconfigurations in the event of disturbances.

Together, the AxoniQ suite of cutting-edge power electronics solutions enables the re-routing of power in real time, rapid fault isolation, and maintaining continuity of power supply while minimizing the impact on the wider grid and avoiding the risk of costly power interruptions. Engineered for interoperability by design, AxoniQ will continue to evolve to enable a sustainable expansion of direct current (DC) grids in the decades ahead.

“Electricity networks are becoming increasingly complex as renewable generation grows and demand patterns evolve. AxoniQ represents a milestone in the evolution of DC grids, enabling the next generation of HVDC systems, helping grid operators integrate renewable power more reliably and affordably while improving grid resilience and transmission efficiency,” said Niklas Persson, CEO, Grid Integration Business Unit at Hitachi Energy. “Hitachi Energy is pioneering the new technology needed today and helping ensure future prosperity.”

The AxoniQ family is part of Hitachi Energy’s Grid-enSure®, a fully integrated solution portfolio to stabilize power systems by strengthening transmission, managing frequency variations and system voltage and addressing capacity constraints. AxoniQ takes its name from axons, the part of a nerve cell (neuron) that carries electrical signals away from the cell body to other neurons, muscles or glands, effectively functioning as the body’s electrical system. Like axons, AxoniQ brings power to life across the grid – intelligently and effectively transmitting electricity between multiple sources and demand points, acting as the vital connection that enables amore responsive, resilient, and interconnected energy system.

AxoniQ has been researched and developed by Hitachi Energy for more than a decade, and its benefits are demonstrated through the company’s work in partnership with TSOs and main industry players with the aim of making future HVDC systems mutually compatible and interoperable by design.

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.

https://www.mhi.com/news/25091101.html

(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, 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."
