Finrenes Advances Biomethane Technology with Successful Pilot Validation

Intro

Finrenes has successfully completed pilot-scale testing of its proprietary biomass pre-treatment technology, marking a significant step toward commercial deployment of renewable biomethane solutions for difficult lignocellulosic feedstocks.

The pilot was carried out with support from the Repsol Foundation, enabling the development and validation of the technology under real operating conditions.

The results confirm the technical feasibility and performance potential of the Finrenes approach, supporting both technology scaling and upcoming commercial applications.

Technology status

Finrenes technology has reached an advanced development stage:

• TRL 8 – Pilot-scale pre-treatment system built and validated
• TRL 6 – Commercial-scale system under development
• BRL 5 – Initial market validation through pilot projects and partner engagement

This positions Finrenes at the transition point from validated technology to early commercial deployment.

Pilot testing and validation

The pilot system has been successfully designed, constructed, and operated with funding support from the Repsol Foundation Innovation Fund. Testing has been conducted in collaboration with industrial partners, including independent validation by a biogas operator.

Key outcomes from pilot testing include:

• Successful pre-treatment of lignocellulosic biomass
• Stable operation of the process concept
• Demonstrated compatibility with anaerobic digestion
• High methane yields from pretreated wood (>200 m³ CH₄/t VS)

The results confirm that Finrenes technology can unlock biomass streams that are typically difficult to process in conventional biogas systems.

Unlocking new feedstock potential

Lignocellulosic biomass such as wood residues, agricultural side streams, and industrial organic waste represent a vast and largely underutilized resource.

Finrenes technology enables:

• Improved digestibility of these materials
• Increased biomethane production
• Utilization of previously unused or low-value biomass

This significantly expands the available feedstock base for renewable gas production.

From pilot to commercial deployment

Following successful pilot validation, Finrenes is now focusing on:

• Scaling the technology toward commercial systems
• Developing first commercial reference projects
• Building partnerships with biogas developers, utilities, and industrial operators
• Expanding applications in both European and Asian markets

The next phase will demonstrate the technology in real-world operational environments and establish the foundation for broader market adoption.

Enabling new energy solutions

Finrenes technology supports emerging energy applications, including:

• Renewable biomethane production for industrial use
• Dispatchable energy for AI data centers
• Waste-to-energy solutions for agro-industrial sectors
• Integration with existing biogas and energy systems

By converting difficult biomass into reliable renewable energy, Finrenes contributes to decarbonization, energy resilience, and circular economy development.
