LIQTECH INTERNATIONAL A/S

Their core work

LiqTech International is a Danish SME specializing in advanced ceramic membrane technology for filtration and separation applications. Their core business revolves around silicon carbide (SiC) membranes used in industrial processes ranging from water purification to catalytic reactors and concentrated solar power. Across their H2020 portfolio, they contribute membrane expertise to projects tackling automotive emissions, water contaminant removal, process intensification, and next-generation manufacturing. They serve as a technology supplier bringing proprietary membrane products into diverse industrial applications.

What they specialise in

How they've shifted over time

LiqTech's early H2020 projects (2015–2017) applied their membrane technology across diverse sectors — reactor optimization (ROMEO), automotive aftertreatment (PARTIAL-PGMs), and concentrated solar power (NEXTOWER) — suggesting they were testing where their ceramic membranes could create the most value. From 2017 onward, the focus sharpened toward water treatment membranes (AQUAlity), catalytic membrane reactors (MACBETH), and membrane manufacturing scale-up (INNOMEM). The trajectory shows a company moving from broad application exploration toward deeper specialization in membrane manufacturing and environmental applications.

LiqTech is converging on scalable membrane manufacturing and environmental filtration — expect them to pursue projects around industrial water reuse, PFAS removal, and membrane production automation.

How they like to work

LiqTech operates exclusively as a participant — they have never coordinated an H2020 project, which is typical for a technology-supplying SME that brings a specific product into larger research consortia. With 104 unique partners across 18 countries in just 6 projects, they consistently join large, multi-partner consortia (averaging ~17 partners per project). This makes them an experienced consortium member who knows how to deliver a defined work package without needing to drive the overall project.

LiqTech has built a broad European network of 104 partners across 18 countries through 6 projects, indicating they are well-connected across multiple research and industrial communities. Their partnerships span universities, research institutes, and industrial players across Western and Southern Europe.

What sets them apart

LiqTech brings something rare to EU consortia: they are a commercial membrane manufacturer, not a lab. While many partners contribute research expertise, LiqTech can supply actual products and pilot-scale manufacturing capability, bridging the gap between laboratory membranes and industrial deployment. Their INNOMEM involvement in open innovation test beds confirms they are positioning as a go-to partner for anyone needing to move membrane technology from TRL 4-5 toward market-ready production.

Highlights from their portfolio

• ROMEO
  Largest single EC contribution (EUR 373,952) and their first H2020 project, establishing their membrane-reactor expertise in the programme.
• MACBETH
  Longest-running project (2019–2025) focused on catalytic membrane reactors and process intensification — represents their deepening specialization.
• INNOMEM
  Positions LiqTech in the membrane manufacturing scale-up ecosystem through an open innovation test bed, signaling a shift toward production-focused collaboration.
