What microfluidics can bring to electrolysis

  • High‑throughput screening of electrocatalysts (PEM/AEM/SOEC) in micro‑cells with precise control of mass transport and local pH.
  • Bubble dynamics control and two-phase flow management to reduce ohmic losses and improve gas removal from porous electrodes.
  • Rapid durability and accelerated‑stress testing (AST) under well-defined gradients of temperature, humidity, and current density.
  • Micro-patterned flow‑fields and channel architectures to optimize pressure drop, water management, and reactant utilization.
  • In‑situ diagnostic sensors (pressure, impedance, optical) embedded in micro‑reactors for real-time degradation mapping.
  • Membrane and ionomer screening (conductivity, crossover, swelling) using chip-based diffusion/permeation rigs.
  • Lab‑on‑chip electrosynthesis for CO₂RR/N₂RR product quantification and selectivity maps at low reagent volumes.
  • Scale‑down replicas of full cells/stacks for fast design‑of‑experiments (DoE) and ML-ready datasets.
  • Thermal management studies (micro‑calorimetry) to quantify heat generation and SOEC thermal transients.
  • Micro‑structured electrodes (e.g., templated foams, nano‑channels) to raise ECSA and sustain higher current densities.

FAQ – Horizon Europe 2026-2027: Best Topics for Electrolysis

Which types of electrolyser topics are prevalent in the 2026-2027 Work Programme?

A relatively consistent triumvirate (i) materials and stack breakthrough (catalysts with drastically reduced Ir/Ru/Pt loading; resilient AEM/PEM membranes; robust SOEC cells), (ii) manufacturing and quality (automated stack assembly, on-line metrology, yield and throughput on gigawatt paths), (iii) system integration and operations (dynamic operation with high-renewables grids, pressurized operation, water management, safety). These are divided into RIA for high-novelty science and IA for pilot-scale demonstrations using industry assets.

Yes. PEM and alkaline are the workhorses for near-term capacity; AEM is appealing for low-critical-metal routes; and SOEC offers high-efficiency hydrogen with industrial waste heat or high-temperature steam. Cross-learning (e.g., PEM/AEM coating processes applied to SOEC electrodes, or alkaline BOP simplification borrowed from PEM) is generally well received by evaluators.

In the case of RIA: measured progress such as ≥50% reduction in noble-metal loading, ≥2000 hours of durability at target current densities with <2%/1,000 h performance degradation, documented cost and LCA baseline, and reproduced protocols.

In case of IA: bankable evidence, MW-class stacks or multi-stack pilots, availability (>95%), start/stop cycling compatible with wind/solar, specific improvements in energy consumption (e.g. towards 50-54 kWh/kg H2 at system level in the case of PEM/alkaline under realistic conditions), therefore, full safety case, and clarity of certification/readiness to offtake.

Reviewers and programme text prioritise four spaces again and again:

  • Critical-metal lean PEM (Ir consumption reduced through gradient electrodes, ultra-thin layers of anode or non-noble bifunctional supports).
  • Industrialised AEM (lasting membranes, control of carbonate, free operation of the process, and independence of caustic).
  • SOEC to hard-to-abate industries (co-electrolysis, dynamic thermal management, stack lifetime in response to frequent load swings).
  • Ready to manufacture gigafactories (inline control of coating/thickness, defect mapping, accelerated stress testing control between materials-stack-system).

Projects are pushed to operate outside ultrapure deionised water; they can tolerate realistic water conditions, can be pretreated with low-energy methods, and can operate safely around offshore or industrial locations. Pretreatment-free seawater electrolysis is not recommended; rather, any calls tend to focus on demineralisation + electrolysis where foulings, scaling, and corrosion have been quantified.

One request is recurring, quick, efficient turndown rate and ramp rates that would go hand in hand with variable RES. Anticipate KPIs of minimum loading (less than 10-20%), start-up (seconds to minutes), and degradation during cycling and participation in ancillary services. Projects that add digital twins, predictive maintenance, and energy scheduling are more likely to deliver better impact.

Full LCA sustainability with a worker-safety plan.

  • Data architecture and traceability: process data, stack genealogy, and a harmonised test book to ensure results are consistent.
  • Recycling and circularity: membrane, catalyst, and BOP recycling and reuse- preferably at pilot scale.
  • Standardised testing: common duty cycles are used in dynamic operation, and the comparisons are useful.

For electrolysis in 2026-2027, envelope costs are expected to be in the €20-80M per topic and €4-20M per project ranges, depending on whether it is an RIA or an IA with large pilots. Several of these IA demonstrations with MW-scale stacks are priced at 8-15M, while materials-intensive RIAs are priced at 4-8M.

Microfluidics is useful where the traditional ones are slow or blind:

  • Catalyst ink screening at scale (dozens–hundreds of compositions/day), mapping viscosity, dispersion, porosity, and resulting overpotentials.
  • To minimise mass transfer loss and ohmic drop at high current densities, bubble management is studied using on-chip visualisation.
  • Gradient electrodes and gradient membranes through micro-patterned coating, which allows ultra-low utilisation of Ir or Ru without a collapse in performance.
  • Early delamination, crossover, and hot spot detection Operando diagnostics (optical/IR/pressure microsensors).
  • Pre-pilot derisking of brine/pretreatment by corrosion and fouling micro-reactors.
  • ICQ modules of thickness, porosity, and defect mapping, which fit on roll-to-roll lines.

These are easily mapped to RIAs (methods/materials) and IAs (yield, uptime, safety), and the iteration cycles are reduced by an order of magnitude.

Opportunities and deadlines are concentrated in December-June, with spring/autumn bankruptcies in 2026 and 2027. The two-stage calls usually exhibit a pattern of opening in December – March/April, followed by a September/October full proposal. Single-stage IA lines are opened in late spring and closed early in the fall. You need to build your internal drafting so that you can be finished 6-8 weeks before the EC deadline, allowing consortium iteration and compliance checks.

A small team, with a fully developed value-chain:

  • Industrial anchors (Stack OEMs, EPCs, offtakers) that administer sites and assets.
  • Experts in the method (membranes, coatings, safety, grid codes, digital twins, LCA /SSbD, recycling).
  • A microfluidics SME, which is in charge of high-throughput screening, inline metrology, and process intensification.
  • Test and certification bodies to seal compliance at an early stage.

Based on practice within Horizon proposals, the addition of a specialised SME that combines engineering with proposal architecture is likely to increase the official success probability by about twice as much, primarily because risks, KPIs, and validation tracks become tangible rather than hypothetical.
