Haffner Energy (Designer, manufacturer and supplier of renewable energy solutions) has announced the launch of a new energy offering dedicated to data centers, available immediately and already the subject of initial commercial proposals.

The French company says its solution addresses three challenges it considers critical to data center development: securing high electrical power quickly without placing additional strain on electricity grids, decarbonizing energy supply, and managing water consumption.

A Differentiated Commercial Opportunity

Philippe Haffner, Chairman and Chief Executive Officer, framed the data center market as a particularly attractive segment for the company's growth strategy. "A single project can call for more than 10 modules, with each module integrated into a full-service data center offering generating about USD 6.985 million in revenue, nearly three times what a module used solely for syngas production would bring in," he said.

Haffner added that the additional revenue does not require a proportional increase in industrial capacity because some complementary equipment is supplied by specialized partners.

The company says it intends to reshape its existing CORE100 program as a result, setting aside a significant share of it for data center projects. The new offering builds on the modular architecture developed under CORE100 and on a new variant called the C-iB, designed specifically for high-power, multi-module installations.

Decentralized Power from Local Biomass

The core premise of Haffner Energy's offering is the generation of renewable, dispatchable electricity close to data centers using local residual biomass.

The company describes this as a decentralized solution that can operate alongside the power grid and substantially reduce the electrical load that must be drawn from it. This approach, it says, allows data center growth to proceed without necessarily waiting for grid upgrades sized for a facility's final power requirements.

The C-iB modules are described as compact, standardized, and cost-effective. Adapted from the earlier C-iC module, the C-iB is purpose-built for multi-module installations, enabling the sharing of certain common functions, increasing production capacity per module, reducing costs, and enabling the co-production of biochar.

Installations are designed to reach tens of megawatts and beyond, depending on customer requirements. The modular design also allows energy capacity to be added progressively as computing capacity is built out, which the company says reduces execution risk.

Engineered for Tier IV Availability Standards

One of the central claims in Haffner Energy's offering is its ability to guarantee energy availability above 99.995%, the level associated with Tier IV infrastructure.

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 activates during exceptional periods when the capacity from the biomass units becomes temporarily insufficient to deliver the full power required. The company states that natural gas is expected to account for less than 0.1% of primary energy consumed.

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

Storable Energy Without Weather Dependency

Unlike solar and wind power, biomass is storable and available on demand. Haffner Energy says several weeks' worth of supply can be stored on-site or nearby, independent of weather conditions.

This characteristic is presented as a structural advantage over intermittent renewable sources when it comes to meeting the continuous, high-availability power requirements of data center operations.

The company's technology is described as compatible with all types of biomass, capable of processing a range of forestry and agricultural resources. This flexibility is said to allow a single project to diversify its local sourcing and strengthen the resilience of its supply.

Combined Electricity and Cooling from a Single System

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.

The system also powers lithium bromide absorption chillers, converting heat available at around 90 degrees Celsius into chilled water at approximately 4 degrees Celsius. Haffner Energy states that all of a data center's cooling needs can thereby be met using recovered heat rather than electricity and water.

Track Record and European Consortium Involvement

Haffner Energy points to an existing reference project in support of its credentials in this space. The company led the engineering and construction of a trigeneration plant in Luxembourg that supplies electricity, heat, and cooling to Kiowatt, powering LuxConnect, which it describes as Europe's first green data center.

The company is also a founding member of the European ÆTHER consortium, which is a candidate for the AI Gigafactory call for tenders launched by the European Commission. Haffner Energy states it is drawing on its track record in this area as it pursues the data center market more broadly.

The company is headquartered in Vitry-le-François, France, and made the announcement on August 28, 2026.

Europe's Data Center Pipeline Is Moving Fast. Is Your Intelligence Keeping Up?

Across Europe, the race to build, expand, and future-proof data center infrastructure has never been more competitive. Hyperscalers, colocation providers, and sovereign cloud initiatives are all driving a surge of activity that spans dozens of markets simultaneously, and the window to position yourself ahead of key developments is narrow.

Whether you are an equipment supplier, construction contractor, or investment firm with exposure to the European data center sector, having fragmented or delayed project intelligence is a liability you cannot afford. The Global Project Tracking (GPT) platform by Blackridge Research was built to eliminate that blind spot, consolidating project-level data from pre-planning through to completion into a single, continuously updated environment.

From hyperscale campuses in the Nordics to edge facilities in Southern Europe, the GPT platform gives your team the structured visibility needed to prioritize outreach, benchmark activity, and make decisions with confidence rather than guesswork.
