Terrensis Invited by Japanese Authorities as Natural Hydrogen Expertise Gains International Recognition
Terrensis has announced that it was invited by Japanese authorities to participate in a series of high-profile events focused on natural hydrogen, highlighting the company's growing international profile within the emerging sector.
The company participated in the first Expert Workshop hosted by JOGMEC (Japan Organization for Metals and Energy Security), where Terrensis executives presented their experience developing natural hydrogen projects and discussed technical, geological, and industrial aspects of the sector. The event brought together government agencies, researchers, and major Japanese industrial groups that are actively evaluating natural hydrogen opportunities.
Terrensis also participated in discussions with representatives of the European Union delegation in Japan regarding the role natural hydrogen could play in strengthening energy security and supporting future industrial cooperation between Europe and Japan.
The company highlighted its exploration achievements across both Africa and Europe. According to Terrensis, its leadership team contributed to the development of a natural hydrogen field in Africa where nearly pure hydrogen was identified through an 18-well drilling campaign. In Europe, the company has secured two natural hydrogen exploration permits in the Pyrenees, including what it describes as the first exclusive exploration permit granted for natural hydrogen in Europe.
Terrensis also presented its technical innovations at the JpGU-AGU Joint Annual Meeting, one of Japan's largest geoscience conferences, where natural hydrogen was featured as a growing area of scientific interest.

Paris – June 8th, 2026 - Terrensis, a pioneer company in the exploration and development of natural hydrogen, after contributing to the work of CIFAR (Canadian Institute for Advanced Research) in 2024 and the Royal Society (UK) report on natural hydrogen in 2025, has been recently invited by the Japanese authorities to participate in several leading international events dedicated to this new energy resource. This mission confirms Terrensis' position among the leading players in an emerging industry called upon to contribute to the growing challenges of energy sovereignty and decarbonization.
On May 28, 2026, Terrensis spoke at the 1st Expert Workshop held at the JOGMEC (Japan Organization for Metals and Energy Security), the Japanese government agency responsible for energy security and the supply of strategic resources.
On this occasion, Vincent Bordmann, CEO, and Jean-Marc Fleury, CSO and SVP Exploration, presented the work carried out by Terrensis on its European projects and shared their feedback on the technical, geological and industrial challenges related to natural hydrogen.
They then participated in a panel discussion with industry leaders, scientists, and representatives of Japanese government agencies, including NEDO (New Energy and Industrial Technology Development), in front of an audience of Japan's major energy and industrial players, some of which (Mitsubishi Heavy Industries, Osaka Gas, Toyota Motor Corporation, ENEOS Xplora, Mitsubishi Gas Chemical) have already started to invest in this emerging natural hydrogen sector.
Terrensis' mission to Japan was also an opportunity to discuss with the Delegation of the European Union to Japan the role that natural hydrogen could play in strengthening energy sovereignty and in developing new industrial cooperation between Europe and Japan.
This invitation is a continuation of the relationship developed by Terrensis with the Japanese ecosystem since its participation at Smart Energy Week Autumn 2025, where Terrensis had been short listed, selected and invited, as part of the EU Business Hub program.
Expertise built on unique achievements.
For several years, Terrensis has been developing its own methodology for exploring natural hydrogen, based on unique know-how, both in intra-cratonic contexts and in mountain ranges, two favorable geological environments to the generation, migration and accumulation of natural hydrogen.
▪ On the African continent, the founders and senior executives of Terrensis are to date the only team to have contributed to the success of an 18-wells drilling campaign where they designed, delineated and validated a field of almost pure natural hydrogen (98%), with hydrogen gas flow rates in all wells.
▪ On the European continent, Terrensis is now focusing on the Pyrenees, one of the most promising geological contexts in Europe. Terrensis has reached two major milestones with the obtaining in 2023 of the 1st Exclusive Exploration Permit granted in Europe for natural hydrogen, followed in 2025 by a 2nd Permit, making Terrensis one of the forerunners in the development of this new energy sector on the continent.
Terrensis' technical innovations were also presented on May 29, 2026, at the JpGU-AGU (Japan Geoscience Union – American Geophysical Union) Joint Annual Meeting, one of Japan's leading international geoscience conferences, once again highlighting Terrensis' leadership role in this emerging sector. Jean-Marc Fleury was the co-convenor of the session on natural hydrogen.
This international recognition comes as Terrensis continues to accelerate its innovation and territorial development programs in France, supported by several institutional partners.
A vision that combines robust geological concepts and territorial anchoring.
In addition to technological innovations, Terrensis applies its know-how integrating social, societal and territorial dimensions in all its exploration projects.
This approach, which is regularly presented at international conferences and institutional events, aims to build projects that create value for the territories, by combining innovation, dialogue with stakeholders and local economic development.
"We are grateful to JOGMEC for inviting us to this event, to share with them our vision on exploration aimed at discovering significant accumulations of natural hydrogen in gaseous form, as well as our technological, social and societal innovations, which are vectors of territorial attractiveness of our projects. This invitation confirms the growing interest of major industrial nations in natural hydrogen and recognizes the expertise developed by Terrensis over several years" says Vincent Bordmann, Chief Executive Officer of Terrensis.
Jean-Marc Fleury, Terrensis' Scientific and Exploration Director, adds: "Exploration is the cornerstone of the development of the natural hydrogen sector. The discussions we had in Japan testify to the extraordinary interest of our Japanese interlocutors in accelerating exploration efforts, particularly in the unique geological context of Japan, and to a common desire to accelerate scientific knowledge and industrial deployment of this resource, based on the feedback of pioneers in this sector."
