Their core work

PSYCTOTHERM is a Greek SME based in Piraeus specializing in thermal energy systems — particularly heat pumps, thermal storage, and heat-to-power conversion technologies. They develop and integrate heating/cooling solutions for buildings and agricultural facilities, working on both component-level innovation (thermochemical and phase-change storage materials) and system-level energy management. Their work spans from residential energy storage installations to livestock farming energy systems, consistently focused on reducing fossil fuel dependency through smart thermal technologies.

What they specialise in

How they've shifted over time

PSYCTOTHERM started in 2016 with a focused SME Phase 1 project on low-temperature heat-to-power conversion (IE-E), signaling early-stage R&D ambitions. From 2019 onward, they expanded significantly into integrated renewable energy systems for buildings (RES4BUILD, MiniStor) and then into agricultural energy applications (RES4LIVE). The shift from a single heat recovery concept to multi-technology thermal storage, PV-thermal hybrids, and biomethane systems shows a clear broadening from component-level innovation toward full system integration across multiple application domains.

Moving toward cross-sector thermal energy integration — expect future work combining building and agricultural energy systems with advanced storage technologies.

How they like to work

PSYCTOTHERM primarily operates as a participant in larger consortia (3 of 4 projects), contributing specialized thermal engineering expertise rather than leading projects. Their single coordination was an SME Phase 1 feasibility study, typical for small companies testing a concept before scaling. With 52 unique partners across 15 countries, they are well-networked for their size and comfortable working in large international teams.

Despite being a small company, PSYCTOTHERM has collaborated with 52 different partners across 15 countries, indicating broad European reach built through participation in sizable Innovation Action and Research consortia.

What sets them apart

PSYCTOTHERM occupies a niche at the intersection of thermal storage materials, heat pump systems, and real-world energy management — a combination few SMEs can offer end-to-end. Their ability to apply thermal expertise across both buildings and agricultural settings makes them versatile partners for energy efficiency projects. For consortium builders, they bring hands-on SME engineering capacity to complement university research, with proven experience in pilot testing and system integration.

Highlights from their portfolio

• MiniStor
  Largest funding (EUR 579K) — develops compact residential thermal and electrical storage using thermochemical and phase-change materials, their core technical showcase.
• RES4LIVE
  Unusual cross-sector application — brings thermal energy expertise into livestock farming, including biomethane tractors and animal thermal comfort systems.
• IE-E
  Their only coordinated project (SME Phase 1) — marks the origin of their heat recovery focus and entrepreneurial ambition.
