(Haffner Energy/Globe Newswire) ata centers set to become a major contributor to Haffner Energy’s business and results: a modular, standardized offering delivering local, resilient, decarbonized energy, with guaranteed availability that can exceed 99.995%

Vitry-le-François, France – August 28, 2026, 8:00 a.m. CEST -- Haffner Energy announces the launch of a new energy offering dedicated to data centers, now available and already the subject of initial commercial proposals. The Company aims to address three challenges that have become critical to data center development: quickly securing high electrical power at high-efficiency without adding further strain on the grid, decarbonizing their energy supply, and managing their water needs.

This new offering builds on the modular architecture developed under CORE100, and on its new C-iB variant, designed for high-power, multi-module installations.

Haffner Energy is a founding member of the European ÆTHER consortium, a candidate for the “AI Gigafactory” call for tenders launched by the European Commission. The Company draws on its track record in this area, having led the engineering and construction of a trigeneration plant in Luxembourg that supplies electricity, heat, and cooling to Kiowatt, powering LuxConnect, Europe’s first green data center.

Philippe Haffner, Chairman and Chief Executive Officer, said: “Data centers are an especially attractive opportunity for Haffner Energy, precisely because our value proposition is so differentiated. A single project can call for more than 10 modules, with each module integrated into a full-service data center offering generating about €6 million in revenue — nearly three times what a module used solely for syngas production would bring in. That additional revenue doesn’t require a proportional increase in our industrial capacity, since some of the complementary equipment is supplied by specialized partners. Our offering thus addresses the market’s three key requirements: availability, speed of deployment, and decarbonization.”

Energy Is No Longer a Limiting Factor for Data Center Growth

The growth of cloud computing, and especially artificial intelligence, is driving an unprecedented surge in demand for computing capacity — and, in turn, for electricity — even as data centers face growing criticism over their carbon footprint, water consumption, and the strain they place on power grids.

Access to sufficient electrical power has therefore become a decisive factor in siting decisions and deployment timelines for new computing capacity.

Haffner Energy offers a decentralized solution: generating renewable, dispatchable, round-the-clock, and cost-competitive electricity near data centers, from local residual biomass.

The solution can operate alongside the power grid and substantially reduce the power that must be drawn from it, allowing data center growth to proceed without necessarily waiting for grid upgrades sized for its final power requirements.

Small Modules Built to Deliver Very Large Power Capacities

Haffner Energy’s value proposition rests on compact, standardized, cost-effective C-iB modules. Adapted from the C-iC, the C-iB is purpose-built for multi-module installations, making it possible to share certain common functions, significantly increase production capacity per module, reduce costs, and co-produce biochar.

This new offering is leading Haffner Energy to reshape CORE100, setting aside a significant share of it for data centers.

The installations are designed to reach tens of megawatts and beyond, depending on customer needs. Their modularity makes it possible to add energy capacity progressively as computing capacity is built out, while reducing execution risk.

Guaranteed Availability That Can Exceed 99.995%

In a configuration comprising ten modules, two of which are held in redundancy, the architecture is supplemented by a limited, on-demand supply of natural gas that steps in during exceptional periods of unavailability. This combination is designed to guarantee the data center an energy availability above 99.995% — the level required for Tier IV infrastructure.

This partial reliance on natural gas is limited to periods when the capacity available from the C-iC units becomes temporarily insufficient to deliver the full power required. Natural gas is expected to account for less than 0.1% of primary energy.

The multi-module configuration also allows maintenance to be performed sequentially while the other modules remain in production, limiting the impact of any unplanned equipment outage. Standardization, together with the repeated use of identical equipment, further helps reduce lead times and costs.

A Renewable Energy Source That Is Storable, Available on Demand, and Flexible

Unlike intermittent renewable energy sources, biomass is storable and available on demand: several weeks’ worth of supply can be stored on-site or nearby, independent of weather conditions.

Haffner Energy’s technology is also compatible with all types of biomass and can process a range of forestry and agricultural resources. This allows a single project to diversify its local sourcing and strengthen its resilience.

Generating Electricity and Cooling Simultaneously, at High Efficiency

The heat generated during electricity production is recovered through a combined cycle, achieving an overall electrical efficiency of around 55% of the energy contained in the syngas produced.

It also powers lithium bromide absorption chillers, converting heat available at around 90°C into chilled water at approximately 4°C.

All of the data center’s cooling needs are thus met using recovered heat rather than electricity and water.

The partial recovery of water contained in biomass, in the form of condensate, can also help reduce the site’s net water needs.

Haffner Energy Already Involved in Europe’s AI Gigafactories Through ÆTHER

Haffner Energy is a founding member of the European ÆTHER consortium, alongside 2CRSi, the ÉS group, Socomec, and Projex, among others. The consortium brings together European players from the energy, infrastructure, cloud, semiconductor, and high-performance computing sectors, with the ambition of developing sovereign, deeply decarbonized European AI Gigafactories.

ÆTHER is a candidate for the “AI Gigafactory” call-for-tenders launched by the European Commission and is working to develop its first campuses in the Strasbourg region. Haffner Energy contributes its resilient, local renewable energy production solutions to the initiative.

This participation already places Haffner Energy at the heart of an ecosystem that brings together the key skills needed to develop next-generation data centers, providing fertile ground for the rollout of its new offering.

OroCarbo reserves 12 SYNOCA® C-iC units from Haffner Energy, generating up to €30M in potential revenue (Haffner Energy)

Excerpt from Haffner Energy: The units, representing 12% of the CORE100 program, are intended for renewable hydrogen and power projects in the Western United States --

Haffner Energy announces that California-based project developer OroCarbo has confirmed the reservation of 12 SYNOCA® C-iC units under its CORE100 program.

CORE100 is Haffner Energy's industrial program for the deployment of the first 100 standardized C-iC units. Designed to accelerate commercial deployment through standardization and series production, the program enables customers to reserve production slots for modular units that can be deployed individually or combined to serve larger projects.

OroCarbo intends to deploy the units as part of its development of local renewable energy hubs in California, Oregon, and Washington State. The projects will convert locally available residual biomass into renewable syngas, primarily for renewable hydrogen for mobility and local power generation in areas where grid capacity or reliability is constrained.

Marcella Franchi, Chief Commercial Officer and Head of SAF at Haffner Energy, said: “This reservation for 12 C-iC units marks a new step in our partnership with OroCarbo: the roll-out of CORE100 across the Western United States. Our vision is to produce energy close to both resources and demand, transforming local biomass into renewable hydrogen and power. Local, resilient energy that can be replicated at scale: that is the ambition of CORE100.”

From one project to a multi-site deployment

Haffner Energy and OroCarbo began working together in 2025 on a 100 tons/day biomethanol project in California. The first phase, an independent carbon-intensity study, was successfully completed during Haffner Energy's 2025-2026 financial year with results supporting the strong decarbonization potential of the project.

While the biomethanol project has subsequently been put on hold pending sufficient long-term methanol offtake commitments, the work carried out together has opened the way for a broader collaboration between Haffner Energy and OroCarbo across multiple renewable energy applications and sites. OroCarbo has broadened its development strategy towards a portfolio of renewable energy projects addressing different local energy needs. Its reservation of 12 C-iC units reflects this transition from a single project to a multi-project, multi-site approach.

Brian Wong, Founder and Managing Member of OroCarbo, said: “Our ambition is to develop local renewable energy hubs that turn abundant residual biomass into clean energy where it is needed. We see significant opportunities both for renewable hydrogen in mobility and for local power generation in areas where grid capacity or reliability is a constraint. Reserving 12 SYNOCA® C-iC units is an important step towards building that network with Haffner Energy.”

A modular platform for hydrogen and power

Each SYNOCA® C-iC unit is designed to convert residual biomass into renewable syngas using Haffner Energy's proprietary thermolysis technology. Several units can be combined according to the capacity required by each project, while their standardized design supports replication across multiple sites.

For OroCarbo's projects, Haffner Energy's scope of supply will be limited to the SYNOCA® C-iC units, together with the engineering required for their integration into the overall plants. The downstream equipment converting renewable syngas into hydrogen or power will be selected and sourced in the United States. Adaptation and certification of the equipment to applicable US standards are not included in Haffner Energy's scope of supply. This approach is intended to facilitate compliance with US standards, maximize local content and US industrial partnerships, and reduce the impact of import tariffs and transatlantic logistics.

The projects are expected to use locally available residual biomass, including forestry and agricultural residues. In California, the valuation of forestry residues can notably contribute to forest management in areas exposed to wildfire risk.

12% of CORE100 reserved by one customer

OroCarbo's reservation covers 12 SYNOCA® C-iC units for a total reservation fee of €100,000. Based on the current contractual price of €2.5M per unit, the twelve units represent up to €30M in potential future revenue for Haffner Energy.

The CORE100 program continues to progress. While Haffner Energy does not intend to communicate individually on each reservation, the Company will provide a comprehensive update on the program shortly. READ MORE
