Electrochaea GmbH

Their core work

Electrochaea is a German technology SME that develops biological methanation — a process using archaea microorganisms to convert renewable hydrogen and CO2 into pipeline-grade synthetic methane (e-methane). Their core technology enables Power-to-Gas energy storage, allowing surplus renewable electricity to be stored in existing natural gas infrastructure. The company has progressed from participating in large-scale energy storage demonstrations (STOREandGO) to leading its own scale-up project (Echaea), positioning biological methanation as a building block of the European Green Deal.

What they specialise in

How they've shifted over time

Electrochaea's H2020 trajectory shows a clear progression from technology participant to technology leader. Their early involvement (2016) in STOREandGO placed them inside a large consortium demonstrating Power-to-Gas concepts, where they contributed their biological methanation know-how as one component of a broader storage portfolio. By 2020, they had secured EUR 2.5M as coordinator of their own SME Instrument project (Echaea), explicitly focused on scaling their proprietary technology — signaling a shift from proving the concept to commercializing it as a Green Deal solution.

Electrochaea is moving from R&D participation toward commercial-scale deployment of biological methanation, making them increasingly relevant for projects requiring near-market Power-to-Gas technology.

How they like to work

Electrochaea operates as both a specialist contributor in large consortia and a project leader for its core technology. With 57 unique partners across 13 countries from just 3 projects, they are comfortable in large, diverse consortia (STOREandGO was a major Innovation Action). Their shift to coordinating the Echaea project under the SME Instrument shows growing confidence in leading focused, technology-specific efforts — a typical trajectory for a deep-tech SME moving toward market.

Despite only 3 projects, Electrochaea has built a broad European network of 57 partners across 13 countries, largely through participation in major energy storage consortia. Their network spans the energy storage and Power-to-Gas ecosystem across Western and Central Europe.

What sets them apart

Electrochaea occupies a rare niche: they are one of very few companies worldwide commercializing biological methanation using archaea-based biocatalysts. Unlike chemical (Sabatier) methanation competitors, their biological process operates at lower temperatures and pressures, with higher tolerance for impurities in CO2 feedstock. For consortium builders, they bring a proprietary, near-market technology that directly converts renewable hydrogen and waste CO2 into grid-injectable methane — a concrete hardware solution, not a consultancy or research group.

Highlights from their portfolio

• Echaea
  Electrochaea's flagship project as coordinator (EUR 2.5M) — an SME Instrument grant to scale their biological methanation technology, signaling commercial readiness.
• STOREandGO
  Major Innovation Action on large-scale Power-to-Gas with EUR 2M to Electrochaea alone — provided real-world demonstration data for their methanation reactor across multiple European sites.
