EPIC POWER CONVERTERS SL

Their core work

Epic Power Converters is a Spanish SME based in Zaragoza that designs and manufactures power electronic converters for energy applications. Their work spans power management systems for energy storage (including vanadium redox flow batteries and supercapacitors), PEM electrolyzers for hydrogen production, and energy-efficient power systems for buildings. They bring specialized electronics and control algorithm expertise to EU research consortia, translating laboratory energy concepts into functional hardware and control systems.

What they specialise in

How they've shifted over time

Epic Power started with a small SME Instrument feasibility study (LESS, 2015) on energy recovery in building elevators — a niche but practical application of their power converter technology. They then moved into hydrogen territory with PEM electrolyzers for off-grid renewables (ELY4OFF, 2016-2019), and most recently shifted toward hybrid energy storage combining vanadium redox flow batteries with supercapacitors (HyFlow, 2020-2024). The trajectory shows a clear move from simple energy efficiency applications toward increasingly complex, multi-component energy storage and conversion systems.

Epic Power is moving toward advanced battery-supercapacitor hybrid systems with sophisticated control software — positioning them at the intersection of power electronics hardware and intelligent energy management.

How they like to work

Epic Power operates primarily as a specialist partner in EU consortia, though they have also led one project (LESS) as coordinator using the SME Instrument. With 14 unique partners across 9 countries from just 3 projects, they connect with diverse European teams rather than sticking to repeat collaborators. This suggests they are adaptable and comfortable integrating into new consortia as the power electronics specialist.

Despite only three projects, Epic Power has built connections with 14 different partners across 9 European countries, indicating broad geographic integration rather than reliance on a local or national network.

What sets them apart

Epic Power fills a specific gap that many energy research consortia need: a company that can design and build the actual power conversion hardware connecting energy sources to storage and loads. As an SME, they are more agile and cost-effective than large electronics firms, while their progression from simple energy recovery to complex hybrid storage control shows genuine technical growth. For consortium builders, they offer hands-on power electronics engineering rather than just research — they make things work.

Highlights from their portfolio

• HyFlow
  Their largest funded project (EUR 296,627), working on an ambitious hybrid storage system combining vanadium redox flow batteries with supercapacitors — a technically demanding integration challenge.
• ELY4OFF
  Their highest single funding (EUR 337,862), contributing to PEM electrolyzer development for off-grid renewables under the FCH2 Joint Undertaking — linking them to the hydrogen economy.
• LESS
  Their only coordinator role, won through the competitive SME Instrument Phase 1, demonstrating entrepreneurial initiative in energy-efficient building systems.
