Over 15 years in the making, Genvia’s disruptive electrolyser technology is built on more than a decade of pioneering R&D work, which has evolved to create an industrial-scale solution.

Committed to continuous improvement

With key sites at strategic locations across France, the Genvia technology network is accelerating the continuous development of electrolyser solutions at scale that are commercial, cost-effective, reliable and sustainable.

And, by enabling customers to produce hydrogen on site, Genvia solutions also safeguard industry by reducing external dependencies and transportation requirements while protecting local jobs.

Genvia’s high-efficiency solid oxide electrolyser technology is a vital part of clean, efficient, high-performance industries of the future.

The technology delivers more electrically-efficient electrolysis performance when compared to existing PEM and alkaline-based systems. Due to the waste heat produced, these technologies cannot achieve the high level of energy efficiency needed to be a viable long-term alternative for industrial applications.

By contrast Genvia technology is being engineered specifically to meet the needs of industrial specifications, systems and solutions at

scale. Genvia solutions represent the culmination of systems engineering design, based on a deep understanding of the challenges faced by our cement, chemical and steel partners in decarbonising their plants.

Genvia is working with different cross-industry groups including as part of a joint industry project with DNV in Norway – a collaboration that will assure technical excellence by helping to create the framework for certification.

Genvia will reduce lifecycle costs for customers by:

  • Increasing the power density of each stack
  • Scaling up manufacturing to reduce cost per stack
  • Scaling projects to optimise balance of plant (BOP) costs

Genvia will extend the lifetime of every electrolyser by:

  • Reducing cell degradation
  • Designing a fault-tolerant system
  • Developing zero-defect manufacturing

Put more of the energy to work

The Genvia approach allows you to make the greatest use of the heat, chemical and electrical energy present within the electrolysis system.

For industrial applications likely to consume high volumes of hydrogen, the economic viability of using an electrolyser for decarbonisation is defined by the costs of electricity.

Genvia’s thermally-charged electrolysis process actively consumes industrial heat so that less additional energy is needed to split the water; reducing the electrical input required to produce each kg of hydrogen.

This approach delivers the most energy-efficient electrolysis performance available at scale, with 28% more hydrogen produced for every kWh of electrical energy input.

Thermally-charged electrolysis accepts heat input via three distinct mechanisms:

Steam generation at 150°C

Feed gas preheating at 150-750°C

Directly into the stack at 750-800°C

Genvia reduces electrical input requirements by:

Optimising reaction conditions

Chasing every joule of loss

Swapping electrical for heat energy

Making a big difference doesn’t always involve the complete reinvention of your process.

The first Genvia high-performance electrolyser module is expected to be available for purchase in 2027. The commercial product will be based on the innovative module at the core of our demonstration projects deployed with steel, cement and chemical demonstration partners in 2026 and 2027.

It will be possible to place pre-orders for the product from 2025.
