AKTSIASELTS ELCOGEN

Their core work

Elcogen is an Estonian SME that designs and manufactures solid oxide fuel cells (SOFC) and solid oxide electrolysis cells (SOEC) — the core ceramic components that convert fuel to electricity and vice versa. Their H2020 work focuses on scaling up production from lab to mass manufacturing, improving cell performance, and extending SOFC/SOEC applications into ammonia-based energy storage and hydrogen recycling. They are a technology supplier contributing proprietary cell and stack technology to European clean energy consortia.

What they specialise in

How they've shifted over time

Elcogen's early H2020 projects (2017–2018) focused squarely on manufacturing readiness — automating SOFC stack production (qSOFC) and proving commercial viability (BestinclassSOFCs). From 2020 onward, their work broadened significantly: they moved into reversible solid oxide cells, ammonia-based energy storage, and end-of-life recycling of hydrogen technologies. This shift shows a company maturing from "how do we make cells at scale" to "what new applications and lifecycle solutions can our technology serve."

Elcogen is expanding from pure SOFC manufacturing toward reversible solid oxide systems, green ammonia production, and circular economy — positioning themselves as a full-lifecycle solid oxide technology provider.

How they like to work

Elcogen operates primarily as a specialist partner (5 of 6 projects), contributing their proprietary SOFC/SOEC technology to larger consortia. They coordinated one major project (BestinclassSOFCs, their largest at EUR 1.8M), showing they can lead when the topic is core to their business. With 41 unique partners across 13 countries, they maintain a broad European network rather than relying on a small circle of repeat collaborators.

Elcogen has built a wide network of 41 unique consortium partners spanning 13 European countries — notable breadth for a 6-project SME, indicating they are well-connected in the European fuel cell and hydrogen community.

What sets them apart

Elcogen is one of very few European SMEs that both develops and manufactures solid oxide cells at commercial scale — most SOFC work in H2020 sits in universities or large corporates. Their Estonian base gives them cost-competitive manufacturing within the EU, and their project portfolio demonstrates they can supply cells for fuel cell mode, electrolysis mode, and reversible operation. For consortium builders, they offer a rare combination: an agile SME with real production capability in a field dominated by research labs.

Highlights from their portfolio

• BestinclassSOFCs
  Their only coordinated project and by far the largest (EUR 1.8M) — focused on enabling mass market adoption of SOFC systems, signaling serious commercialization ambitions.
• ARENHA
  Represents a strategic pivot into ammonia energy storage using their SOEC expertise — connecting solid oxide technology to the emerging green ammonia economy.
• BEST4Hy
  Extends their involvement into circular economy by addressing end-of-life recycling of fuel cell components and recovery of critical raw materials.
