HDF Energy Breaks Ground on World’s Largest Green Hydrogen-Power Project
29.9.2021 18:53:00 EEST | Business Wire | Press release
HDF Energy (mnemonic code: HDF) and its equity partners, the infrastructure fund Meridiam and the petroleum operator SARA (Rubis Group) today announced the start of the construction of CEOG Renewstable® Power Plant in French Guiana. CEOG is the world’s first multi-megawatt hydrogen power plant, and the largest green hydrogen storage of intermittent electricity sources (128MWh).
Damien HAVARD, CEO of HDF Energy said: “CEOG demonstrates that HDF Renewstable® solution addresses a very large market being all the grids currently powered by fossil fuel power plants. By supplying non-intermittent renewable energy, CEOG – which we are already replicating across the world – opens a new era for renewable energies. We thank our partners Meridiam and SARA (Rubis Group) that have brought a significant value to the development of CEOG, allowing us to launch today this new model of electricity production. “
The Renewstable® power plant, designed and developed by HDF, will supply a 100% renewable, stable and dispatchable power to 10 000 households at a lower cost than the diesel power plant, but without emitting any greenhouse gas, fine particle, noise or fumes. A Renewstable® power plant produces electricity using local sources of clean energy to fully sustain the local needs, reducing exposure to oil price volatility, supply risks, and saving foreign exchange.
Representing a total investment of US$200 million, CEOG is an optimised combination of a solar park, a hydrogen long-term energy storage and a battery (short-term energy storage) to produce 24/7 baseload power. It is the first time that a renewable energy project supplies a grid through a capacity-based Power Purchase Agreement, usually used for thermal power plants. This type of electricity offtake contract guarantees the availability and stability of the electricity produced by CEOG. This last characteristic is essential for powering isolated grids or reducing congestion on large networks.
CEOG is currently being duplicated in about 20 countries such as Mexico, Caribbean island nations, Southern Africa, Indonesia and Australia. The most mature part of this pipeline represents US$1.5 billion of investment. Competitive with diesel power plants, the Renewstable® power plant addresses a large power generation market. HDF has already identified a pipeline of US$3 billion.

Zuper and Vonage Reimagine Network Connectivity for Skilled Trades with Quality on Demand25.2.2026 10:00:00 EET | Press release
Zuper, the AI operating system for the trades, and Vonage, part of Ericsson, have entered into a Memorandum of Understanding (MoU) to enter into a collaboration to integrate Vonage’s network APIs into the Zuper platform. The collaboration will provide Zuper with early access to Vonage network powered solutions, starting with Quality on Demand (QoD), where mobile network performance can be selectively applied to support critical field workflows, delivering improved latency, reliability, and connected experiences for mobile workforces. This press release features multimedia. View the full release here: https://www.businesswire.com/news/home/20260225852261/en/ QoD is the first advanced network API being integrated¹ and represents one component of a larger vision for mobile networks as a platform that aligns network behaviour with application intent as these capabilities continue to be exposed. The ambition is to provide Zuper with programmable mobile network capabilities, powered by Vonag
AI: The New Insider Threat Facing Organizations25.2.2026 10:00:00 EET | Press release
According to the Thales 2026 Data Threat Report, organizations across various markets including automotive, energy, finance and retail say the rapid pace of AI-driven transformation is now their biggest security challenge. Based on the report’s research, conducted by S&P Global 451 Research, 61% cite AI as their top data security risk. The concern is not only about malicious AI, but about the access it is being granted as it shifts from a tool to a trusted insider. This press release features multimedia. View the full release here: https://www.businesswire.com/news/home/20260225599723/en/ ©Thales As enterprises embed AI into workflows, analytics, customer service, and development pipelines, these systems are being granted broad, automated access to enterprise data, often with fewer controls than those applied to human users in a corporate environment. “Insider risk is no longer just about people. It is also about automated systems that have been trusted too quickly,” says Sebastien Can
Industrial Decarbonization: Calderion, WenCo and Terravent Invest in Graforce to Scale Plasma Pyrolysis Globally25.2.2026 09:07:00 EET | Press release
The investor consortium comprising the Paris-based Next Generation Fuels Industrial & Technological fund Calderion (Audacia), alongside infrastructure developer Terravent and WenCo Family Office, announces the closing of a strategic double-digit million-euro financing round for Berlin-based Graforce GmbH. The investment is dedicated to the industrial scale-up of Graforce’s proprietary plasma pyrolysis technology, addressing the growing global demand for cost-efficient low-carbon hydrogen, syngas, and carbon removal solutions that are compatible with existing industrial infrastructures. Disruptive alternative to conventional processes Graforce’s technology aims at replacing CO₂-intensive legacy routes such as steam reforming and classical gasification. By applying plasma to methane, biogas, flare gas, and landfill gas, the process converts these streams into their valuable molecular components instead of emitting them. The result is a high-efficiency production of clean hydrogen and syn
Mevion Medical Systems Announces CE Marking of the MEVION S250-FIT™ Proton Therapy System, Expanding Global Access to Compact Proton Therapy25.2.2026 09:00:00 EET | Press release
Mevion Medical Systems, the global leader in compact proton therapy, today announced that the MEVION S250-FIT Proton Therapy System has successfully completed the conformity assessment process and has received CE Marking under Regulation (EU) 2017/745 (EU MDR). This regulatory milestone enables the marketing, sale, and clinical use of the MEVION S250-FIT system throughout the European Union, building on the system’s existing U.S. FDA 510(k) clearance granted in September 2025. The MEVION S250-FIT is the first and only proton therapy system designed to fit into a standard radiation therapy vault. By enabling cancer centers to use their existing infrastructure, the MEVION S250-FIT dramatically reduces the cost, complexity, and timeline traditionally associated with proton therapy adoption. This opens a new pathway for hospitals and cancer centers across Europe to bring advanced proton treatment to their patients. “With both FDA clearance and CE Marking now in hand, the MEVION S250-FIT is
