SOLIDPOWER GMBH

Their core work

SOLIDPOWER GMBH is a German SME that manufactures and commercializes solid oxide fuel cell (SOFC) systems for combined heat and power applications, primarily targeting residential and small commercial micro-CHP markets. Their core business is turning laboratory-proven SOFC technology into commercially viable products — managing not just hardware development but also the supply chain and support networks needed for large-scale deployment. In both H2020 projects they acted as a third-party technology provider, contributing actual SOFC systems and deployment know-how rather than conducting research. This positions them at the late-stage technology readiness end of the fuel cell sector: building markets, not basic science.

What they specialise in

How they've shifted over time

In their earlier project (PACE, from 2016), SolidPower's contributions revolved around demonstration, large-scale deployment, supply chain readiness, and building support networks — the infrastructure work needed to take a proven fuel cell technology and make it deployable across Europe. By 2018 (ComSos), the focus had sharpened to commercial-scale SOFC systems and formal business planning, suggesting the demonstration phase had delivered results and the company was shifting to replicable commercial operations. The trajectory is a textbook commercialization arc: demonstrate → build supply chain → formalize the business model.

SolidPower is moving past the demonstration phase toward full commercial SOFC deployment, meaning future partnerships would likely center on industrial scale-up, market rollout, or integration with energy service providers rather than technology validation.

How they like to work

SolidPower participated exclusively as a third party in both projects — a role typically taken by organizations that contribute specific technology, products, or IP but do not lead or coordinate the broader research effort. This is characteristic of a focused technology supplier that gets embedded in large consortia as a hardware contributor. Their 28 consortium partners across 9 countries (across just two projects) reflects the pan-European, multi-stakeholder scale typical of Innovation Actions targeting market uptake of energy technology.

Despite only two projects, SolidPower has exposure to 28 unique partners across 9 European countries — a broad network reflecting the full fuel cell value chain from manufacturers and utilities to installers and market developers. Their network is European in scope, consistent with EU-wide fuel cell market development programs.

What sets them apart

SolidPower is one of the few SMEs in Europe that combines SOFC hardware manufacturing with direct involvement in commercial-scale market deployment — rare because most fuel cell companies are either pure technology developers or system integrators, not both. Their third-party role in two major EU Innovation Actions signals they are recognized by large consortia as a credible technology supplier, not merely a research participant. For a consortium builder, SolidPower brings real hardware and real deployment experience, which is precisely what market-uptake projects need to demonstrate to the European Commission.

Highlights from their portfolio

• PACE
  One of the largest EU fuel cell micro-CHP demonstration programs, targeting a competitive European market — SolidPower's inclusion as a technology provider signals their systems were considered market-ready enough for pan-European field trials.
• ComSos
  Focused specifically on commercial-scale SOFC systems with a business plan dimension, making it the most commercially oriented fuel cell project in SolidPower's portfolio and a direct signal of their scale-up ambitions.
