PINFLOW ENERGY STORAGE, S.R.O.

Their core work

Pinflow Energy Storage is a Czech technology SME specialising in electrochemical energy storage systems, with hands-on expertise in redox flow batteries and supercapacitor-based hybrid storage. They contribute to EU research projects as a technology partner, bringing practical knowledge of battery chemistry, system integration, and performance modelling. Their work spans the full stack from electrode materials and membrane evaluation through to lifecycle cost analysis (LCOS/LCA) and the advanced control algorithms that make hybrid storage systems viable in real grid applications. The company sits at the intersection of materials science and applied energy engineering — making them a useful bridge between laboratory research and deployable storage solutions.

What they specialise in

How they've shifted over time

Pinflow's earliest H2020 work (HIGREEW, 2019) was grounded in electrochemistry fundamentals — aqueous organic electrolytes, electrode and membrane materials, and the economic case for green flow batteries via LCA and LCOS analysis. By the time HyFlow started in 2020, the focus had shifted notably toward systems-level engineering: vanadium redox flow batteries operating at high power, hybridisation with supercapacitors, and the control algorithms and dynamic simulations needed to manage a combined storage system. The trajectory is clear — from chemistry and cost justification toward integration, system control, and real-world deployment readiness.

Pinflow is moving up the value chain from materials and cost modelling toward complete hybrid storage system design and intelligent energy management — positioning for industrial and grid-scale application projects.

How they like to work

Pinflow has participated exclusively as a consortium partner across both projects and has never taken a coordinator role, consistent with a specialist SME that contributes targeted technical expertise rather than project management capacity. Both projects are Research and Innovation Actions with medium-to-large consortia, suggesting they are comfortable operating within structured multi-partner research programmes. With 19 unique partners across 10 countries from just two projects, they appear to work with diverse teams rather than a fixed core network.

Pinflow has built a network of 19 consortium partners spanning 10 countries through only two projects, indicating broad European reach for a small company. No geographic concentration is evident from the available data, suggesting their partnerships are driven by technical fit rather than national proximity.

What sets them apart

Pinflow is one of the few Czech SMEs active in both organic aqueous flow battery chemistry and vanadium-supercapacitor hybrid storage within the same EU research portfolio — a rare combination that covers both emerging green chemistries and high-power established systems. Their dual exposure to component-level electrochemistry and system-level control engineering makes them a versatile technical partner for projects that need to bridge the gap between lab materials and grid-connected prototypes. For consortium builders in the energy storage space, they offer a cost-effective specialist alternative to larger institutes without sacrificing depth of technical knowledge.

Highlights from their portfolio

• HyFlow
  The largest funding award Pinflow has received (EUR 405,937) and the most systems-integrated project in their portfolio, combining vanadium redox flow batteries, supercapacitors, advanced control algorithms, and dynamic simulations in a single hybrid storage platform.
• HIGREEW
  Focuses on affordable green flow batteries using aqueous organic electrolytes — a next-generation chemistry that avoids vanadium's cost and supply-chain risks — demonstrating Pinflow's reach beyond conventional flow battery materials.
