LIMMAT SCIENTIFIC AG

Their core work

Limmat Scientific AG is a Swiss private company specializing in advanced energy systems and electrified propulsion engineering. Their work spans two distinct but related domains: energy accumulation and thermal management technologies (PUMP-HEAT), and the conceptual design of hybrid-electric aircraft (HECARRUS). They operate as a specialist technical partner in research consortia, likely contributing simulation, systems engineering, or component-level design expertise. Based in Zug, Switzerland, they bring precision engineering capability to complex multi-disciplinary R&D programs funded under EU Horizon 2020.

What they specialise in

How they've shifted over time

Limmat's early H2020 work (PUMP-HEAT, starting 2017) focused on stationary or industrial energy systems — power and heat accumulation technologies with no aviation dimension. By 2019 their participation shifted entirely toward hybrid-electric aviation with HECARRUS, integrating gas turbines, electric motors, and airframe-level design. The trajectory suggests a deliberate move from general energy storage toward propulsion electrification, with aerospace as the application vector.

Limmat appears to be positioning itself at the intersection of electrification and aerospace propulsion — a high-growth area given Clean Aviation JTI priorities — making them a plausible partner for future hybrid propulsion or urban air mobility projects.

How they like to work

Limmat has participated exclusively as a non-leading partner in both projects, suggesting they engage as a specialist contributor rather than a consortium organiser. Their 18 unique partners across just 2 projects indicates they join mid-to-large consortia where their technical niche complements broader teams. There is no evidence of repeated partnerships, which is consistent with sector-hopping between energy and aviation.

Limmat has built connections with 18 distinct organisations across 7 countries through only 2 projects, reflecting participation in substantial multi-partner consortia. No dominant geographic cluster is identifiable from available data, though Swiss private companies in JTI programmes often work alongside German, French, and Italian aerospace partners.

What sets them apart

Limmat occupies an unusual position as a small Swiss private company (non-SME designation suggests it may be a subsidiary or holding structure) active in both stationary energy systems and aviation propulsion — a combination rare among European research partners. Their Clean Aviation JTI participation (HECARRUS) signals access to a tightly vetted, industrially-oriented consortium network that many academic or SME partners cannot easily enter. For consortium builders needing a Swiss industrial node with cross-domain energy and propulsion expertise, Limmat offers both technical depth and geographic eligibility for Swiss-associated programme participation.

Highlights from their portfolio

• PUMP-HEAT
  Largest funding share (EUR 412,500) and the foundational project establishing Limmat's energy accumulation credentials across both energy and environmental sectors.
• HECARRUS
  Joint Technology Initiative project targeting hybrid-electric commuter aircraft — a highly competitive and industrially significant programme — demonstrating Limmat's capacity to enter top-tier aerospace consortia.
